BIVALENT BROMODOMAIN INHIBITORS AND USES THEREOF
Abstract
The present invention provides bivalent inhibitors of BET
bromodomains, such as compounds of Formulae (I), (II), (III), (IV),
(V), and (VI). Some bromodomain-containing proteins (e.g., BRD4)
have a tandem bromodomain primary structure comprising more than
one bromodomain binding site (e.g., BRD4 comprises BD1 and BD2).
Bivalent inhibitors of BET bromodomains provided herein can target
bromodomains through advantageous multivalent interactions, and can
therefore can be to treat diseases or conditions associated with
bromodomain-containing proteins. The present also provides
pharmaceutical compositions and kits comprising the inventive
compounds, as well as methods of using the inventive compounds.

BACKGROUND OF THE INVENTION
[0003] Cell-cell interactions and signal transduction often depend
on multivalent interactions between receptors and their
corresponding ligands (see, e.g., Mammen et al. Angewandte Chemie
International Edition 1998, 37, 2754-2794). As is often the case in
binding of carbohydrates (e.g., glycoproteins, glycolipids,
polysaccharides, or proteoglycans) to lectins that have several
binding sites, individual weak interactions can be enhanced more
than 1,000-fold through multivalent interactions, a phenomenon
known as the avidity effect (see, e.g., Monsigny et al.
Carbohydrate letters 2000, 4, 35-52). Multivalent ligands that have
either homo- or hetero-binding motifs show avidity by several
mechanisms, such as interactions with oligomeric receptors,
oligomerization of monomeric receptors, or increasing effective
molarity of binding ligands (see, e.g., Kiessling et al. Current
opinion in chemical biology 2000, 4, 696-703). Further, multivalent
ligands can exhibit a prolonged residence time (see, e.g.,
Illendula et al. Science 2015, 347, 779-784). These historical
observations from the natural world establish a strong rationale
for multivalent ligand discovery (see, e.g., Profit, et al. Journal
of the American Chemical Society 1999, 121, 280-283).
[0004] Molecular recognition of chromatin by transcriptional or
epigenetic complexes is often mediated by proteins with single or
multiple "reader" domains, which bind histone proteins, DNA, or
transcription factors in specific post-translational modification
states. In the context of transcriptional activation, recruitment
of histone acetyltransferases leads to N-acetylation (Kac) of
lysine residues on histone proteins and transcription factors.
Local hyperacetylation leads to subsequent recruitment of
co-activator proteins with acetyl-lysine recognition domains, or
bromodomains. A bromodomain is an antiparallel bundle of alpha
helices that recognizes mono- or di-acetylated peptides via a
hydrophobic pocket with an adjacent, conserved asparagine residue
(see, e.g., Filippakopoulos, P. & Knapp, S. Nature reviews.
Drug discovery 2014, 13, 337-356). The BET (bromodomain and
extra-terminal domain) family of human bromodomains are
transcriptional co-activators involved in cell cycle progression,
transcriptional activation and elongation (see, e.g., Zeng, L.

& Zhou, M. M. ACS Chem Biol 2015,
doi:10.1021/acschembio.5b00831). BET bromodomains (BRD2, BRD3, BRD4
and BRDT) are critical mediators of chromatin-dependent signal
transduction from master regulatory transcription factors to RNA
Polymerase II. BRD4, in particular, has emerged as a therapeutic
target in cancer, as a co-activator protein for the prevalent
oncoprotein, MYC (see, e.g., Zuber, J. et al. Nature 2011, 478,
524-528; Delmore, J. E. et al. Cell 2011, 146, 904-917). Further,
BRD4 facilitates transcriptional elongation via recruitment or
activation of the positive transcription elongation factor (P-TEFb)
and displacement of negative regulators (HEXIM1 and 7SK snRNA)
(see, e.g., Yang, Z. et al. Molecular cell 2005, 19, 535-545;
Krueger et al. PloS one 2010, 5, e12335).
[0005] Recently, compounds have been reported to be bromodomain
binding agents, e.g., international PCT publications WO
2015/013635, WO 2015/117083, WO 2015/117055, WO 2015/117053, WO
2015/117087, WO 2014/159392, WO 2014/195951, WO 2012/075383, WO
2011/054553, WO 2011/054841, WO 2011/054844, WO 2011/054845, WO
2011/054846, WO 2011/054848, WO 2011/143669, and WO 2011/161031,
each of which is incorporated herein by reference. Moreover,
Japanese patent application publication JP 2008/156311,
incorporated herein by reference, discloses a benzimidazole
derivative that is a BRD2 bromodomain binding agent and has been
found useful in treating viral infections and inhibiting viral
replication. International PCT publication WO 2009/084693,
incorporated herein by reference, discloses a series of
thienotriazolodiazepine derivatives that inhibit the binding
between an acetylated histone and a bromodomain-containing protein
which are useful as anti-cancer agents. International PCT
publication WO 2011/054843, incorporated herein by reference,
suggests compounds which inhibit the binding of a bromodomain with
its cognate acetylated proteins may be useful in the treatment of
autoimmune and inflammatory diseases.
[0006] The first direct-acting bromodomain antagonist, JQ1, was
reported in 2010 (FIG. 1a) (see, e.g., Filippakopoulos et al.
Nature 2010, 468, 1067-1073; WO 2011/143669). JQ1 is a potent and
BET-selective thieno-1,4-diazepine which binds the critical
asparagine via a methyl-triazolo moiety. JQ1 has proven a valuable
chemical probe for mechanistic and translational research,
providing pharmacologic target validation in predictive models of
solid tumors and hematological diseases. The structure of JQ1 is as
follows:
##STR00002##
[0007] More recently, isoxazole BET inhibitor, I-BET151, was
reported (see, e.g., Dawson, M. A. et al. Nature 2011, 478,
529-533). I-BET151 exhibits comparable performance to JQ1 in
biochemical and cellular assays (see, e.g., FIG. 6). The structure
of I-BET151 is as follows:
##STR00003##
[0008] Already, more than eight BRD4 antagonists have advanced to
human clinical investigation as cancer therapies (see, e.g.,
Tanaka, M. et al. Pharmaceutical patent analyst 2015, 4, 261-284).
To date, all validated BRD4 antagonists are monovalent inhibitors
that interact with either bromodomain 1 (BD1) or bromodomain 2
(BD2) in a selective or non-selective fashion. The significance of
the tandem BET bromodomains is not mechanistically resolved (see,
e.g., Schroder et al. The Journal of biological chemistry 2012,
287, 1090-1099). Chromatin binding is principally influenced by BD1
(see, e.g., Baud, M. G. et al. Science 2014, 346, 638-641), but
genetic and chemical genetic studies identify a role for both
domains in transcriptional activation (see, e.g., Picaud et al.
Proc Natl Acad Sci USA 2013, 110, 19754-19759,
doi:10.1073/pnas.1310658110). Despite progress in this area, there
remains a need for additional potent and safe bromodomain binders.
Given that bromodomain-containing proteins comprise more than one
ligand binding site of interest, multivalent ligands targeting
bromodomain-containing proteins have the potential to be of great
therapeutic value.
SUMMARY OF THE INVENTION
[0009] Gene regulation is fundamentally governed by a reversible,
non-covalent assembly of macromolecules. Signal transduction to RNA
polymerase requires higher-ordered protein complexes, spatially
regulated by assembly factors capable of interpreting the
post-translational modification states of chromatin. Epigenetic
readers are structurally diverse proteins, and each of the
epigenetic readers possesses one or more evolutionarily conserved
effector modules, which recognize covalent modifications of
proteins (e.g., histones) or DNA. The .epsilon.-N-acetylation of
lysine residues (Kac) on histone tails is associated with an open
chromatin architecture and transcriptional activation.
Context-specific molecular recognition of acetyl-lysine is
principally mediated by bromodomains.
[0010] Bromodomain-containing proteins are of substantial
biological interest, as components of transcription factor
complexes (e.g., TBP (TATA box binding protein)-associated factor 1
(TAF1), CREB-binding protein (CBP or CREBBP), P300/CBP-associated
factor (PCAF), and Gcn5), and determinants of epigenetic memory.
There are 41 human proteins containing a total of 57 diverse
bromodomains. Despite large sequence variations, all bromodomains
share a conserved fold comprising a left-handed bundle of four
alpha helices (.alpha..sub.Z, .alpha..sub.A, .alpha..sub.B, and
.alpha..sub.C), linked by diverse loop regions (ZA and BC loops)
that determine substrate specificity. Co-crystal structures with
peptidic substrates showed that the acetyl-lysine is recognized by
a central hydrophobic cavity and is anchored by a hydrogen bond
with an asparagine residue present in most bromodomains. The bromo
and extra-terminal (BET) family (e.g., BRD2, BRD3, BRD4 and BRDT)
shares a common domain architecture comprising two N-terminal
bromodomains that exhibit a high degree of sequence conservation,
and a more divergent C-terminal recruitment domain.
[0011] Recent research has established a compelling rationale for
targeting BRD4 in cancer. BRD4 functions to facilitate cell cycle
progression, and knock-down in cultured cancer cell lines prompts
G1 arrest. BRD4 is an important mediator of transcriptional
elongation, functioning to recruit the positive transcription
elongation factor complex (P-TEFb). Cyclin dependent kinase-9, a
core component of P-TEFb, is a validated target in chronic
lymphocytic leukemia, and has recently been linked to c-Myc
dependent transcription. Bromodomains present in BRD4 recruit
P-TEFb to mitotic chromosomes resulting in increased expression of
growth promoting genes. BRD4 remains bound to transcriptional start
sites of genes expressed during M/G1 but has not been found present
at start sites that are expressed later in the cell cycle.
Knockdown of BRD4 in proliferating cells has been shown to lead to
G1 arrest and apoptosis by decreasing expression levels of genes
important for mitotic progression and survival.
[0012] Importantly, BRD4 has recently been identified as a
component of a recurrent t(15;19) chromosomal translocation in an
aggressive form of human squamous cell carcinoma. Such
translocations express the tandem N-terminal bromodomains of BRD4
as an in-frame chimera with the nuclear protein in testis (NUT)
protein, genetically defining the NUT midline carcinoma (NMC).
Functional studies in patient-derived NMC cell lines have validated
the essential role of the BRD4-NUT oncoprotein in maintaining the
characteristic proliferation advantage and differentiation block of
this malignancy. Notably, RNA silencing of BRD4-NUT gene expression
arrests proliferation and prompts squamous differentiation with a
marked increase in cytokeratin expression. A bromodomain may also
down-regulates Myc and other transcriptional factors, such as
interleukin 7 receptor (IL7R). These observations underscore the
utility and therapeutic potential of a binder or inhibitor of
bromodomain-containing proteins.
[0013] Some bromodomain-containing proteins (e.g., BRD4) have a
tandem bromodomain primary structure including more than one
bromodomain (e.g., BRD4 comprises BD1 and BD2). The present
invention relates in part to bivalent inhibitors of BET
bromodomains, which target bromodomain-containing proteins through
multivalent interactions. The bivalent inhibitors provided herein
are especially potent inhibitors of BET bromodomains and therefore
can be used to treat diseases or conditions associated with
bromodomain-containing proteins.

systems can include one or more heteroatoms in one or both rings.
"Heteroaryl" includes ring systems wherein the heteroaryl ring, as
defined above, is fused with one or more carbocyclyl or
heterocyclyl groups wherein the point of attachment is on the
heteroaryl ring, and in such instances, the number of ring members
continue to designate the number of ring members in the heteroaryl
ring system. "Heteroaryl" also includes ring systems wherein the
heteroaryl ring, as defined above, is fused with one or more aryl
groups wherein the point of attachment is either on the aryl or
heteroaryl ring, and in such instances, the number of ring members
designates the number of ring members in the fused polycyclic
(aryl/heteroaryl) ring system. Polycyclic heteroaryl groups wherein
one ring does not contain a heteroatom (e.g., indolyl, quinolinyl,
carbazolyl, and the like) the point of attachment can be on either
ring, i.e., either the ring bearing a heteroatom (e.g., 2-indolyl)
or the ring that does not contain a heteroatom (e.g.,
5-indolyl).

the term "substituted" means that at least one hydrogen present on
a group is replaced with a permissible substituent, e.g., a
substituent which upon substitution results in a stable compound,
e.g., a compound which does not spontaneously undergo
transformation such as by rearrangement, cyclization, elimination,
or other reaction. Unless otherwise indicated, a "substituted"
group has a substituent at one or more substitutable positions of
the group, and when more than one position in any given structure
is substituted, the substituent is either the same or different at
each position. The term "substituted" is contemplated to include
substitution with all permissible substituents of organic
compounds, and includes any of the substituents described herein
that results in the formation of a stable compound. The present
invention contemplates any and all such combinations in order to
arrive at a stable compound. For purposes of this invention,
heteroatoms such as nitrogen may have hydrogen substituents and/or
any suitable substituent as described herein which satisfy the
valencies of the heteroatoms and results in the formation of a
stable moiety. The invention is not intended to be limited in any
manner by the exemplary substituents described herein.

[0099] A "counterion" or "anionic counterion" is a negatively
charged group associated with a positively charged group in order
to maintain electronic neutrality. An anionic counterion may be
monovalent (i.e., including one formal negative charge). An anionic
counterion may also be multivalent (i.e., including more than one
formal negative charge), such as divalent or trivalent. Exemplary
counterions include halide ions (e.g., F.sup.-, Cl.sup.-, Br.sup.-,
I.sup.-), NO.sub.3.sup.-, ClO.sub.4.sup.-, OH.sup.-,
H.sub.2PO.sub.4.sup.-, HCO.sub.3.sup.-, HSO.sub.4.sup.-, sulfonate

malate, malonate, gluconate, succinate, glutarate, adipate,
pimelate, suberate, azelate, sebacate, salicylate, phthalates,
aspartate, glutamate, and the like), and carboranes.
[0100] As used herein, a "leaving group" (LG) is an art-understood
term referring to a molecular fragment that departs with a pair of
electrons in heterolytic bond cleavage, wherein the molecular
fragment is an anion or neutral molecule. As used herein, a leaving
group can be an atom or a group capable of being displaced by a
nucleophile. See, for example, Smith, March Advanced Organic
Chemistry 6th ed. (501-502). Exemplary leaving groups include, but
are not limited to, halo (e.g., chloro, bromo, iodo) and activated
substituted hydroxyl groups (e.g., --OC(.dbd.O)SR.sup.aa,
--OC(.dbd.O)R.sup.aa, --OCO.sub.2R.sup.aa,
--OC(.dbd.O)N(R.sup.bb).sub.2, --OC(.dbd.NR.sup.bb)R.sup.aa,

R.sup.cc are as defined herein). e.g.e.g.
[0101] As used herein, use of the phrase "at least one instance"
refers to 1, 2, 3, 4, or more instances, but also encompasses a
range, e.g., for example, from 1 to 4, from 1 to 3, from 1 to 2,
from 2 to 4, from 2 to 3, or from 3 to 4 instances, inclusive.
[0102] A "non-hydrogen group" refers to any group that is defined
for a particular variable that is not hydrogen.
[0103] A "non-hydrogen atom" refers to any atom other than
hydrogen.
[0104] These and other exemplary substituents are described in more
detail in the Detailed Description, Examples, and Claims. The
invention is not intended to be limited in any manner by the above
exemplary listing of substituents.
Other Definitions
[0105] The following definitions are more general terms used
throughout the present application.
[0106] As used herein, the term "salt" refers to any and all salts,
and encompasses pharmaceutically acceptable salts.
[0107] The term "pharmaceutically acceptable salt" refers to those
salts which are, within the scope of sound medical judgment,
suitable for use in contact with the tissues of humans and lower
animals without undue toxicity, irritation, allergic response, and
the like, and are commensurate with a reasonable benefit/risk
ratio. Pharmaceutically acceptable salts are well known in the art.
For example, Berge et al. describe pharmaceutically acceptable
salts in detail in J. Pharmaceutical Sciences, 1977, 66, 1-19,
incorporated herein by reference. Pharmaceutically acceptable salts
of the compounds of this invention include those derived from
suitable inorganic and organic acids and bases. Examples of
pharmaceutically acceptable, nontoxic acid addition salts are salts
of an amino group formed with inorganic acids, such as hydrochloric
acid, hydrobromic acid, phosphoric acid, sulfuric acid, and
perchloric acid or with organic acids, such as acetic acid, oxalic
acid, maleic acid, tartaric acid, citric acid, succinic acid, or
malonic acid or by using other methods known in the art such as ion
exchange. Other pharmaceutically acceptable salts include adipate,
alginate, ascorbate, aspartate, benzenesulfonate, benzoate,
bisulfate, borate, butyrate, camphorate, camphorsulfonate, citrate,
cyclopentanepropionate, digluconate, dodecylsulfate,
ethanesulfonate, formate, fumarate, glucoheptonate,
glycerophosphate, gluconate, hemisulfate, heptanoate, hexanoate,
hydroiodide, 2-hydroxy-ethanesulfonate, lactobionate, lactate,
laurate, lauryl sulfate, malate, maleate, malonate,
methanesulfonate, 2-naphthalenesulfonate, nicotinate, nitrate,
oleate, oxalate, palmitate, pamoate, pectinate, persulfate,
3-phenylpropionate, phosphate, picrate, pivalate, propionate,
stearate, succinate, sulfate, tartrate, thiocyanate,
p-toluenesulfonate, undecanoate, valerate salts, and the like.
Salts derived from appropriate bases include alkali metal, alkaline
earth metal, ammonium, and N.sup.+(C.sub.1-4 alkyl).sub.4.sup.-
salts. Representative alkali or alkaline earth metal salts include
sodium, lithium, potassium, calcium, magnesium, and the like.
Further pharmaceutically acceptable salts include, when
appropriate, nontoxic ammonium, quaternary ammonium, and amine
cations formed using counterions such as halide, hydroxide,
carboxylate, sulfate, phosphate, nitrate, lower alkyl sulfonate,
and aryl sulfonate.
[0108] The term "solvate" refers to forms of the compound, or a
salt thereof, that are associated with a solvent, usually by a
solvolysis reaction. This physical association may include hydrogen
bonding. Conventional solvents include water, methanol, ethanol,
acetic acid, DMSO, THF, diethyl ether, and the like. The compounds
described herein may be prepared, e.g., in crystalline form, and
may be solvated. Suitable solvates include pharmaceutically
acceptable solvates and further include both stoichiometric
solvates and non-stoichiometric solvates. In certain instances, the
solvate will be capable of isolation, for example, when one or more
solvent molecules are incorporated in the crystal lattice of a
crystalline solid. "Solvate" encompasses both solution-phase and
isolatable solvates. Representative solvates include hydrates,
ethanolates, and methanolates.
[0109] The term "hydrate" refers to a compound that is associated
with water. Typically, the number of the water molecules contained
in a hydrate of a compound is in a definite ratio to the number of
the compound molecules in the hydrate. Therefore, a hydrate of a
compound may be represented, for example, by the general formula
R.xH.sub.2O, wherein R is the compound, and x is a number greater
than 0. A given compound may form more than one type of hydrate,
including, e.g., monohydrates (x is 1), lower hydrates (x is a
number greater than 0 and smaller than 1, e.g., hemihydrates (R.0.5
H.sub.2O)), and polyhydrates (x is a number greater than 1, e.g.,
dihydrates (R.2 H.sub.2O) and hexahydrates (R.6 H.sub.2O)).
[0110] The term "tautomers" or "tautomeric" refers to two or more
interconvertible compounds resulting from at least one formal
migration of a hydrogen atom and at least one change in valency
(e.g., a single bond to a double bond, a triple bond to a single
bond, or vice versa). The exact ratio of the tautomers depends on
several factors, including temperature, solvent, and pH.
Tautomerizations (i.e., the reaction providing a tautomeric pair)
may catalyzed by acid or base. Exemplary tautomerizations include
keto-to-enol, amide-to-imide, lactam-to-lactim, enamine-to-imine,
and enamine-to-(a different enamine) tautomerizations.
[0111] It is also to be understood that compounds that have the
same molecular formula but differ in the nature or sequence of
bonding of their atoms or the arrangement of their atoms in space
are termed "isomers". Isomers that differ in the arrangement of
their atoms in space are termed "stereoisomers".
[0112] Stereoisomers that are not mirror images of one another are
termed "diastereomers" and those that are non-superimposable mirror
images of each other are termed "enantiomers". When a compound has
an asymmetric center, for example, it is bonded to four different
groups, a pair of enantiomers is possible. An enantiomer can be
characterized by the absolute configuration of its asymmetric
center and is described by the R- and S-sequencing rules of Cahn
and Prelog, or by the manner in which the molecule rotates the
plane of polarized light and designated as dextrorotatory or
levorotatory (i.e., as (+) or (-)-isomers respectively). A chiral
compound can exist as either individual enantiomer or as a mixture
thereof. A mixture containing equal proportions of the enantiomers
is called a "racemic mixture".
[0113] The term "polymorph" refers to a crystalline form of a
compound (or a salt, hydrate, or solvate thereof). All polymorphs
have the same elemental composition. Different crystalline forms
usually have different X-ray diffraction patterns, infrared
spectra, melting points, density, hardness, crystal shape, optical
and electrical properties, stability, and solubility.
Recrystallization solvent, rate of crystallization, storage
temperature, and other factors may cause one crystal form to
dominate. Various polymorphs of a compound can be prepared by
crystallization under different conditions.
[0114] The term "prodrugs" refers to compounds that have cleavable
groups and become by solvolysis or under physiological conditions
the compounds described herein, which are pharmaceutically active
in vivo. Such examples include, but are not limited to, choline
ester derivatives and the like, N-alkylmorpholine esters and the
like. Other derivatives of the compounds described herein have
activity in both their acid and acid derivative forms, but in the
acid sensitive form often offer advantages of solubility, tissue
compatibility, or delayed release in the mammalian organism (see,
e.g., Bundgard, H., Design of Prodrugs, pp. 7-9, 21-24, Elsevier,
Amsterdam 1985). Prodrugs include acid derivatives well known to
practitioners of the art, such as, for example, esters prepared by
reaction of the parent acid with a suitable alcohol, or amides
prepared by reaction of the parent acid compound with a substituted
or unsubstituted amine, or acid anhydrides, or mixed anhydrides.
Simple aliphatic or aromatic esters, amides, and anhydrides derived
from acidic groups pendant on the compounds described herein are
particular prodrugs. In some cases it is desirable to prepare
double ester type prodrugs such as (acyloxy)alkyl esters or
((alkoxycarbonyl)oxy)alkylesters. C.sub.1-C.sub.8 alkyl,
C.sub.2-C.sub.8 alkenyl, C.sub.2-C.sub.8 alkynyl, aryl,
C.sub.7-C.sub.12 substituted aryl, and C.sub.7-C.sub.12 arylalkyl
esters of the compounds described herein may be preferred.
[0115] The terms "composition" and "formulation" are used
interchangeably.
[0116] The term "gene" refers to a nucleic acid fragment that
expresses a specific protein, including regulatory sequences
preceding (5'non-coding sequences) and following (3'non-coding
sequences) the coding sequence. "Native gene" refers to a gene as
found in nature with its own regulatory sequences. "Chimeric gene"
or "chimeric construct" refers to any gene or a construct, not a
native gene, comprising regulatory and coding sequences that are
not found together in nature. Accordingly, a chimeric gene or
chimeric construct may comprise regulatory sequences and coding
sequences that are derived from different sources, or regulatory
sequences and coding sequences derived from the same source, but
arranged in a manner different than that found in nature.
"Endogenous gene" refers to a native gene in its natural location
in the genome of an organism. A "foreign" gene refers to a gene not
normally found in the host organism, but which is introduced into
the host organism by gene transfer. Foreign genes can comprise
native genes inserted into a non-native organism, or chimeric
genes. A "transgene" is a gene that has been introduced into the
genome by a transformation procedure.
[0117] The term "histone" refers to highly alkaline proteins found
in eukaryotic cell nuclei that package and order the DNA into
structural units called nucleosomes. They are the chief protein
components of chromatin, acting as spools around which DNA winds,
and play a role in gene regulation. In certain embodiments, the
histone is histone H1 (e.g., histone H1F, histone HIH). In certain
embodiments, the histone is histone H2A (e.g., histone H2AF,
histone H2A1, histone H2A2). In certain embodiments, the histone is
histone H2B (e.g., histone H2BF, histone H2B1, histone H2B2). In
certain embodiments, the histone is histone H3 (e.g., histone H3A1,
histone H3A2, histone H3A3). In certain embodiments, the histone is
histone H4 (e.g., histone H41, histone H44).
[0118] The term "bromodomain" refers to a protein domain that
recognizes acetylated lysine residues such as those on the
N-terminal tails of histones. In certain embodiments, a bromodomain
of a BET protein comprises about 110 amino acids and shares a
conserved fold comprising a left-handed bundle of four
alpha-helices linked by diverse loop regions that interact with
chromatin. In certain embodiments, the bromodomain is ASH1L
(GenBank ID: gi|8922081), ATAD2 (GenBank ID: gi|24497618), BAZ2B
(GenBank ID: gi7304923), BRD1 (GenBank ID: gi|11321642), BRD2(1)

gi|148612882), CREBBP (GenBank ID: gi|14758056), EP300 (GenBank ID:
gi|150345997), FALZ (GenBank ID: gi|38788274), GCN5L2 (GenBank ID:
gi|10835101), KIAA1240 (GenBank ID: gi|51460532), LOC93349 (GenBank
ID: gi|134133279), PB1(1) (GenBank ID: gi|130794372), PB1(2)
(GenBank ID: gi|30794372), PB1(3) (GenBank ID: gi|30794372), PB1(5)
(GenBank ID: gi|30794372), PB1(6) (GenBank ID: gi|30794372), PCAF
(GenBank ID: gi|40805843), PHIP(2) (GenBank ID: gi|34996489),
SMARCA2 (GenBank ID: gi|48255900), SMARCA4 (GenBank ID:
gi|21071056), SP140 (GenBank ID: gi|52487219), TAF1(1) (GenBank ID:
gi|20357585), TAF1(2) (GenBank ID: gi|20357585), TAF1L(1) (GenBank
ID: gi|24429572), TAF1L(2) (GenBank ID: gi|124429572), TIF1
(GenBank ID: gi|14971415), TRIM28 (GenBank ID: gi|5032179), or
WDR9(2) (GenBank ID: gi16445436).
[0119] The term "bromodomain-containing protein" or "bromodomain
protein" refers to a protein, whether wild-type or mutant, natural
or synthetic, truncated or complete, or a variant thereof, that
possesses the minimum amino acid sequence sufficient for a
functional bromodomain capable of mediating molecular recognition
of acetyl-lysine of acetylated lysine residues on a second protein
(e.g., a histone), such as on the tails of histones.
Bromodomain-containing proteins include, for example, fusion
proteins comprising a bromodomain and an additional portion having
a desired functionality (e.g., a reporter portion).
[0120] A "kinase" is a type of enzyme that transfers phosphate
groups from high energy donor molecules, such as ATP, to specific
substrates, referred to as phosphorylation. Kinases are part of the
larger family of phosphotransferases. One of the largest groups of
kinases are protein kinases, which act on and modify the activity
of specific proteins. Kinases are used extensively to transmit
signals and control complex processes in cells. Various other
kinases act on small molecules such as lipids, carbohydrates, amino
acids, and nucleotides, either for signaling or to prime them for
metabolic pathways. Kinases are often named after their substrates.
More than 500 different protein kinases have been identified in
humans. These exemplary human protein kinases include, but are not
limited to, AAK1, ABL, ACK, ACTR2, ACTR2B, AKT1, AKT2, AKT3, ALK,

[0121] The terms "composition" and "formulation" are used
interchangeably.
[0122] A "subject" to which administration is contemplated refers
to a human (i.e., male or female of any age group, e.g., pediatric
subject (e.g., infant, child, or adolescent) or adult subject
(e.g., young adult, middle-aged adult, or senior adult)) or
non-human animal. In certain embodiments, the non-human animal is a
mammal (e.g., primate (e.g., cynomolgus monkey or rhesus monkey),
commercially relevant mammal (e.g., cattle, pig, horse, sheep,
goat, cat, or dog), or bird (e.g., commercially relevant bird, such
as chicken, duck, goose, or turkey)). In certain embodiments, the

buccal swabs), or any material containing biomolecules that is
derived from a first biological sample.
[0125] The term "administer," "administering," or "administration"
refers to implanting, absorbing, ingesting, injecting, inhaling, or
otherwise introducing a compound described herein, or a composition
thereof, in or on a subject.
[0126] The terms "condition," "disease," and "disorder" are used
interchangeably.
[0127] The terms "treatment," "treat," and "treating" refer to
reversing, alleviating, delaying the onset of, or inhibiting the
progress of a disease described herein. In some embodiments,
treatment may be administered after one or more signs or symptoms
of the disease have developed or have been observed. In other
embodiments, treatment may be administered in the absence of signs
or symptoms of the disease. For example, treatment may be
administered to a susceptible subject prior to the onset of
symptoms (e.g., in light of a history of symptoms and/or in light
of exposure to a pathogen). Treatment may also be continued after
symptoms have resolved, for example, to delay or prevent
recurrence.
[0128] An "effective amount" of a compound described herein refers
to an amount sufficient to elicit the desired biological response,
i.e., treating the condition. As will be appreciated by those of
ordinary skill in this art, the effective amount of a compound
described herein may vary depending on such factors as the desired
biological endpoint, the pharmacokinetics of the compound, the
condition being treated, the mode of administration, and the age
and health of the subject. An effective amount encompasses
therapeutic and prophylactic treatment.
[0129] A "therapeutically effective amount" of a compound described
herein is an amount sufficient to provide a therapeutic benefit in
the treatment of a condition or to delay or minimize one or more
symptoms associated with the condition. A therapeutically effective
amount of a compound means an amount of therapeutic agent, alone or
in combination with other therapies, which provides a therapeutic
benefit in the treatment of the condition. The term
"therapeutically effective amount" can encompass an amount that
improves overall therapy, reduces or avoids symptoms, signs, or
causes of the condition, and/or enhances the therapeutic efficacy
of another therapeutic agent. In certain embodiments, a
therapeutically effective amount is effective for inhibiting the
activity of a bromodomain-containing protein. In certain
embodiments, a therapeutically effective amount is effective for
treating a disease described herein. In certain embodiments, a
therapeutically effective amount is effective for inhibiting the
activity of a bromodomain-containing protein and for treating a
disease described herein.
[0130] A "prophylactically effective amount" of a compound
described herein is an amount sufficient to prevent a condition, or
one or more symptoms associated with the condition or prevent its
recurrence. A prophylactically effective amount of a compound means
an amount of a therapeutic agent, alone or in combination with
other agents, which provides a prophylactic benefit in the
prevention of the condition. The term "prophylactically effective
amount" can encompass an amount that improves overall prophylaxis
or enhances the prophylactic efficacy of another prophylactic
agent. In certain embodiments, a prophylactically effective amount
is effective for inhibiting the activity of a
bromodomain-containing protein. In certain embodiments, a
prophylactically effective amount is effective for preventing a
disease described herein. In certain embodiments, a
prophylactically effective amount is effective for inhibiting the
activity of a bromodomain-containing protein and for preventing a
disease described herein.
[0131] The term "synergistic" or "synergy" refers to the phenomenon
when two or more different agents working together produce enhanced
results as compared with the effects of any one of the agents
working alone. For example, "synergistic" effects are achieved when
the co-administration of two compounds results in enhanced
biological effects as compared with the biological effects observed
for each individual compound administered in the absence of the
other.
[0132] The term "inhibition," "inhibiting," "inhibit," or
"inhibitor" refer to the ability of a compound to reduce, slow,
halt or prevent activity of a particular biological process (e.g.,
activity of a bromodomain and/or a bromodomain-containing protein)
in a cell relative to vehicle. In some embodiments, the term refers
to a reduction of the level of enzyme activity, e.g., (bromodomain,
bromodomain-containing protein activity), to a level that is
statistically significantly lower than an initial level, which may,
for example, be a baseline level of enzyme activity. In some
embodiments, the term refers to a reduction of the level of enzyme
activity, e.g., (bromodomain, bromodomain-containing protein)
activity, to a level that is less than 75%, less than 50%, less
than 40%, less than 30%, less than 25%, less than 20%, less than
10%, less than 9%, less than 8%, less than 7%, less than 6%, less
than 5%, less than 4%, less than 3%, less than 2%, less than 1%,
less than 0.5%, less than 0.1%, less than 0.01%, less than 0.001%,
or less than 0.0001% of an initial level, which may, for example,
be a baseline level of enzyme activity.
[0133] When a compound, pharmaceutical composition, method, use, or
kit is referred to as "selectively," "specifically," or
"competitively" binding a first protein or a first chromatin, the
compound, pharmaceutical composition, method, use, or kit binds the
first protein or the first chromatin with a higher binding affinity
(e.g., not less than about 2-fold, not less than about 5-fold, not
less than about 10-fold, not less than about 30-fold, not less than
about 100-fold, not less than about 1,000-fold, or not less than
about 10,000-fold) than binding a second protein or second
chromatin that is different from the first protein and the first
chromatin. When a compound, pharmaceutical composition, method,
use, or kit is referred to as "selectively," "specifically," or
"competitively" modulating (e.g., increasing or inhibiting) the
activity of a bromodomain-containing protein, the compound,
pharmaceutical composition, method, use, or kit modulates the
activity of the bromodomain-containing protein to a greater extent
(e.g., not less than about 2-fold, not less than about 5-fold, not
less than about 10-fold, not less than about 30-fold, not less than
about 100-fold, not less than about 1,000-fold, or not less than
about 10,000-fold) than the activity of at least one protein that
is different from the bromodomain-containing protein.
[0134] The term "aberrant activity" refers to activity deviating
from normal activity. The term "increased activity" refers to
activity higher than normal activity.
[0135] A "proliferative disease" refers to a disease that occurs
due to abnormal growth or extension by the multiplication of cells
(Walker, Cambridge Dictionary of Biology; Cambridge University
Press: Cambridge, UK, 1990). A proliferative disease may be
associated with: 1) the pathological proliferation of normally
quiescent cells; 2) the pathological migration of cells from their
normal location (e.g., metastasis of neoplastic cells); 3) the
pathological expression of proteolytic enzymes such as the matrix
metalloproteinases (e.g., collagenases, gelatinases, and
elastases); or 4) the pathological angiogenesis as in proliferative
retinopathy and tumor metastasis. Exemplary proliferative diseases
include cancers (i.e., "malignant neoplasms"), benign neoplasms,
diseases associated with angiogenesis, inflammatory diseases, and
autoimmune diseases.
[0136] The term "angiogenesis" refers to the physiological process
through which new blood vessels form from pre-existing vessels.
Angiogenesis is distinct from vasculogenesis, which is the de novo
formation of endothelial cells from mesoderm cell precursors. The
first vessels in a developing embryo form through vasculogenesis,
after which angiogenesis is responsible for most blood vessel
growth during normal or abnormal development. Angiogenesis is a
vital process in growth and development, as well as in wound
healing and in the formation of granulation tissue. However,
angiogenesis is also a fundamental step in the transition of tumors
from a benign state to a malignant one, leading to the use of
angiogenesis inhibitors in the treatment of cancer. Angiogenesis
may be chemically stimulated by angiogenic proteins, such as growth
factors (e.g., VEGF). "Pathological angiogenesis" refers to
abnormal (e.g., excessive or insufficient) angiogenesis that
amounts to and/or is associated with a disease.
[0137] The terms "neoplasm" and "tumor" are used interchangeably
and refer to an abnormal mass of tissue wherein the growth of the
mass surpasses and is not coordinated with the growth of a normal
tissue. A neoplasm or tumor may be "benign" or "malignant,"
depending on the following characteristics: degree of cellular
differentiation (including morphology and functionality), rate of
growth, local invasion, and metastasis. A "benign neoplasm" is
generally well differentiated, has characteristically slower growth
than a malignant neoplasm, and remains localized to the site of
origin. In addition, a benign neoplasm does not have the capacity
to infiltrate, invade, or metastasize to distant sites. Exemplary
benign neoplasms include, but are not limited to, lipoma,
chondroma, adenomas, acrochordon, senile angiomas, seborrheic
keratoses, lentigos, and sebaceous hyperplasias. In some cases,
certain "benign" tumors may later give rise to malignant neoplasms,
which may result from additional genetic changes in a subpopulation
of the tumor's neoplastic cells, and these tumors are referred to
as "pre-malignant neoplasms." An exemplary pre-malignant neoplasm
is a teratoma. In contrast, a "malignant neoplasm" is generally
poorly differentiated (anaplasia) and has characteristically rapid
growth accompanied by progressive infiltration, invasion, and
destruction of the surrounding tissue. Furthermore, a malignant
neoplasm generally has the capacity to metastasize to distant
sites. The term "metastasis," "metastatic," or "metastasize" refers
to the spread or migration of cancerous cells from a primary or
original tumor to another organ or tissue and is typically
identifiable by the presence of a "secondary tumor" or "secondary
cell mass" of the tissue type of the primary or original tumor and
not of that of the organ or tissue in which the secondary
(metastatic) tumor is located. For example, a prostate cancer that
has migrated to bone is said to be metastasized prostate cancer and
includes cancerous prostate cancer cells growing in bone
tissue.
[0138] The term "cancer" refers to a malignant neoplasm (Stedman's
Medical Dictionary, 25th ed.; Hensyl ed.; Williams & Wilkins:
Philadelphia, 1990). Exemplary cancers include, but are not limited
to, acoustic neuroma; adenocarcinoma; adrenal gland cancer; anal

[0139] The term "inflammatory disease" refers to a disease caused
by, resulting from, or resulting in inflammation. The term
"inflammatory disease" may also refer to a dysregulated
inflammatory reaction that causes an exaggerated response by
macrophages, granulocytes, and/or T-lymphocytes leading to abnormal

[0140] An "autoimmune disease" refers to a disease arising from an
inappropriate immune response of the body of a subject against
substances and tissues normally present in the body. In other
words, the immune system mistakes some part of the body as a
pathogen and attacks its own cells. This may be restricted to
certain organs (e.g., in autoimmune thyroiditis) or involve a
particular tissue in different places (e.g., Goodpasture's disease
which may affect the basement membrane in both the lung and
kidney). The treatment of autoimmune diseases is typically with
immunosuppression, e.g., medications which decrease the immune
response. Exemplary autoimmune diseases include, but are not
limited to, glomerulonephritis, Goodpasture's syndrome, necrotizing
vasculitis, lymphadenitis, peri-arteritis nodosa, systemic lupus

[0142] The term "metabolic disorder" refers to any disorder that
involves an alteration in the normal metabolism of carbohydrates,
lipids, proteins, nucleic acids, or a combination thereof. A
metabolic disorder is associated with either a deficiency or excess
in a metabolic pathway resulting in an imbalance in metabolism of
nucleic acids, proteins, lipids, and/or carbohydrates. Factors
affecting metabolism include, and are not limited to, the endocrine
(hormonal) control system (e.g., the insulin pathway, the
enteroendocrine hormones including GLP-1, PYY or the like), the
neural control system (e.g., GLP-1 in the brain), or the like.
Examples of metabolic disorders include, but are not limited to,
diabetes (e.g., Type I diabetes, Type II diabetes, gestational
diabetes), hyperglycemia, hyperinsulinemia, insulin resistance, and
obesity.
BRIEF DESCRIPTION OF THE DRAWINGS
[0143] The accompanying drawings, which constitute a part of this
specification, illustrate several embodiments of the invention and
together with the description, serve to explain the principles of
the invention.
[0144] FIGS. 1a-1d. Rational design of bivalent BET family
bromodomain inhibitors. FIG. 1a shows the structure and activity of
the prototype BET family bromodomain inhibitor JQ1. FIG. 1b shows a
crystal structure of BRD4(1) with JQ1 (pdb 3MXF). JQ1 binds to
BRD4(1) via its acetyl-lysine mimetic triazole moiety and has
solvent exposed regions at the 2 position of the thiophene and the
6 position of the diazepine, which are amenable to chemical
modification (indicated by arrows). FIG. 1c shows the primary
structure of human BRD4. The domain structure illustrates the
potential of dimeric JQ1 analogs linked through the C6 and C2
positions to bridge the two bromodomains in an intra- and/or
intermolecular fashion. FIG. 1d shows the general chemical
structure and design of dimeric JQ1 molecules. Linkage sites at the
6 position of the diazepine and the 2 position of the thiophene are
indicated.
[0145] FIGS. 2a-2b. Homodimeric bivalent inhibitors. FIG. 2a shows
that the (6+6) homodimer did not increase biochemical or cellular
activity. FIG. 2b shows that the (2+2) homodimer showed a 20-fold
improved inhibitory activity for BRD4(1), but this did not
translate into cellular activity. AlphaScreen.TM. and cellular data
points represent at least 2 or 4 replicates respectively
.+-.SD.
[0146] FIGS. 3a-3e. Heterodimeric bivalent inhibitors and activity
optimization. FIGS. 3a and 3b show the general chemical structure
of heterodimeric bivalent inhibitors with changes in both (a)
linker length and (b) stereochemistry. FIG. 3c shows a heat-map of

construct, and full length BRD4. Biochemical and cellular data
points represent at least 2 or 4 replicates respectively
.+-.SD.
[0147] FIGS. 4a-4d. Biochemical and physicochemical properties of
bivalent inhibitors. FIG. 4a shows that size-exclusion
chromatography showed that heterodimeric compound (6S+2S)-PEG1
completely shifted BRD4(1) to a dimeric state when added in a 1:2
ratio whereas excess (6R+2R)-PEG1 or JQ1 failed to shift the
monomer peak. FIG. 4b shows isothermal titration calorimetry data
showing that (6S+2S)-PEG1 bound to BRD4(1) in a 1:2 ratio,
indicating dimerization whereas JQ1 bound in a 1:1 ratio. FIG. 4c

bromodomain inhibition. FIG. 5a shows the chemical structure of
MT1. FIG. 5b shows BRD4(1) biochemical and MV4;11 and NMC797
cellular activity of MT1. Biochemical and cellular data points
represent at least 2 or 4 replicates respectively .+-.SD. FIG. 5c
shows that MT1 induced dimerization of recombinant BRD4(1) by
AlphaScreen.TM.; triplicate means.+-.SD; normalized to dimethyl
sulfoxide vehicle. FIG. 5d shows the cocrystal structure of MT1

[0418] Liquid dosage forms for oral and parenteral administration
include pharmaceutically acceptable emulsions, microemulsions,
solutions, suspensions, syrups and elixirs. In addition to the
active ingredients, the liquid dosage forms may comprise inert
diluents commonly used in the art such as, for example, water or
other solvents, solubilizing agents and emulsifiers such as ethyl
alcohol, isopropyl alcohol, ethyl carbonate, ethyl acetate, benzyl

certain embodiments for parenteral administration, the conjugates
described herein are mixed with solubilizing agents such as
Cremophor.RTM., alcohols, oils, modified oils, glycols,
polysorbates, cyclodextrins, polymers, and mixtures thereof.
[0419] Injectable preparations, for example, sterile injectable
aqueous or oleaginous suspensions can be formulated according to
the known art using suitable dispersing or wetting agents and
suspending agents. The sterile injectable preparation can be a
sterile injectable solution, suspension, or emulsion in a nontoxic
parenterally acceptable diluent or solvent, for example, as a
solution in 1,3-butanediol. Among the acceptable vehicles and
solvents that can be employed are water, Ringer's solution, U.S.P.,
and isotonic sodium chloride solution. In addition, sterile, fixed
oils are conventionally employed as a solvent or suspending medium.
For this purpose any bland fixed oil can be employed including
synthetic mono- or di-glycerides. In addition, fatty acids such as
oleic acid are used in the preparation of injectables.
[0420] The injectable formulations can be sterilized, for example,
by filtration through a bacterial-retaining filter, or by
incorporating sterilizing agents in the form of sterile solid
compositions which can be dissolved or dispersed in sterile water
or other sterile injectable medium prior to use.
[0421] In order to prolong the effect of a drug, it is often
desirable to slow the absorption of the drug from subcutaneous or
intramuscular injection. This can be accomplished by the use of a
liquid suspension of crystalline or amorphous material with poor
water solubility. The rate of absorption of the drug then depends
upon its rate of dissolution, which, in turn, may depend upon
crystal size and crystalline form. Alternatively, delayed
absorption of a parenterally administered drug form may be
accomplished by dissolving or suspending the drug in an oil
vehicle.
[0422] Compositions for rectal or vaginal administration are
typically suppositories which can be prepared by mixing the
conjugates described herein with suitable non-irritating excipients
or carriers such as cocoa butter, polyethylene glycol, or a
suppository wax which are solid at ambient temperature but liquid
at body temperature and therefore melt in the rectum or vaginal
cavity and release the active ingredient.
[0423] Solid dosage forms for oral administration include capsules,
tablets, pills, powders, and granules. In such solid dosage forms,
the active ingredient is mixed with at least one inert,
pharmaceutically acceptable excipient or carrier such as sodium
citrate or dicalcium phosphate and/or (a) fillers or extenders such
as starches, lactose, sucrose, glucose, mannitol, and silicic acid,
(b) binders such as, for example, carboxymethylcellulose,
alginates, gelatin, polyvinylpyrrolidinone, sucrose, and acacia,
(c) humectants such as glycerol, (d) disintegrating agents such as
agar, calcium carbonate, potato or tapioca starch, alginic acid,
certain silicates, and sodium carbonate, (e) solution retarding
agents such as paraffin, (f) absorption accelerators such as
quaternary ammonium compounds, (g) wetting agents such as, for
example, cetyl alcohol and glycerol monostearate, (h) absorbents
such as kaolin and bentonite clay, and (i) lubricants such as talc,
calcium stearate, magnesium stearate, solid polyethylene glycols,
sodium lauryl sulfate, and mixtures thereof. In the case of
capsules, tablets, and pills, the dosage form may include a
buffering agent.
[0424] Solid compositions of a similar type can be employed as
fillers in soft and hard-filled gelatin capsules using such
excipients as lactose or milk sugar as well as high molecular
weight polyethylene glycols and the like. The solid dosage forms of
tablets, dragees, capsules, pills, and granules can be prepared
with coatings and shells such as enteric coatings and other
coatings well known in the art of pharmacology. They may optionally
comprise opacifying agents and can be of a composition that they
release the active ingredient(s) only, or preferentially, in a
certain part of the intestinal tract, optionally, in a delayed
manner. Examples of encapsulating compositions which can be used
include polymeric substances and waxes. Solid compositions of a
similar type can be employed as fillers in soft and hard-filled
gelatin capsules using such excipients as lactose or milk sugar as
well as high molecular weight polyethylene glycols and the
like.
[0425] The active ingredient can be in a micro-encapsulated form
with one or more excipients as noted above. The solid dosage forms
of tablets, dragees, capsules, pills, and granules can be prepared
with coatings and shells such as enteric coatings, release
controlling coatings, and other coatings well known in the
pharmaceutical formulating art. In such solid dosage forms the
active ingredient can be admixed with at least one inert diluent
such as sucrose, lactose, or starch. Such dosage forms may
comprise, as is normal practice, additional substances other than
inert diluents, e.g., tableting lubricants and other tableting aids
such a magnesium stearate and microcrystalline cellulose. In the
case of capsules, tablets and pills, the dosage forms may comprise
buffering agents. They may optionally comprise opacifying agents
and can be of a composition that they release the active
ingredient(s) only, or preferentially, in a certain part of the
intestinal tract, optionally, in a delayed manner. Examples of
encapsulating agents which can be used include polymeric substances
and waxes.
[0426] Dosage forms for topical and/or transdermal administration
of a compound described herein may include ointments, pastes,
creams, lotions, gels, powders, solutions, sprays, inhalants,
and/or patches. Generally, the active ingredient is admixed under
sterile conditions with a pharmaceutically acceptable carrier or
excipient and/or any needed preservatives and/or buffers as can be
required. Additionally, the present disclosure contemplates the use
of transdermal patches, which often have the added advantage of
providing controlled delivery of an active ingredient to the body.
Such dosage forms can be prepared, for example, by dissolving
and/or dispensing the active ingredient in the proper medium.
Alternatively or additionally, the rate can be controlled by either
providing a rate controlling membrane and/or by dispersing the
active ingredient in a polymer matrix and/or gel.
[0427] Intradermal compositions can be administered by devices
which limit the effective penetration length of a needle into the
skin. Alternatively or additionally, conventional syringes can be
used in the classical mantoux method of intradermal administration.
Jet injection devices which deliver liquid formulations to the
dermis via a liquid jet injector and/or via a needle which pierces
the stratum corneum and produces a jet which reaches the dermis are
suitable. Ballistic powder/particle delivery devices which use
compressed gas to accelerate the compound in powder form through
the outer layers of the skin to the dermis are suitable.
[0428] Formulations suitable for topical administration include,
but are not limited to, liquid and/or semi-liquid preparations such
as liniments, lotions, oil-in-water and/or water-in-oil emulsions
such as creams, ointments, and/or pastes, and/or solutions and/or
suspensions. Topically administrable formulations may, for example,
comprise from about 1% to about 10% (w/w) active ingredient,
although the concentration of the active ingredient can be as high
as the solubility limit of the active ingredient in the solvent.
Formulations for topical administration may further comprise one or
more of the additional ingredients described herein.
[0429] A pharmaceutical composition described herein can be
prepared, packaged, and/or sold in a formulation suitable for
pulmonary administration via the buccal cavity. Such a formulation
may comprise dry particles which comprise the active ingredient and
which have a diameter in the range from about 0.5 to about 7
nanometers, or from about 1 to about 6 nanometers. Such
compositions are conveniently in the form of dry powders for
administration using a device comprising a dry powder reservoir to
which a stream of propellant can be directed to disperse the powder
and/or using a self-propelling solvent/powder dispensing container
such as a device comprising the active ingredient dissolved and/or
suspended in a low-boiling propellant in a sealed container. Such
powders comprise particles wherein at least 98% of the particles by
weight have a diameter greater than 0.5 nanometers and at least 95%
of the particles by number have a diameter less than 7 nanometers.
Alternatively, at least 95% of the particles by weight have a
diameter greater than 1 nanometer and at least 90% of the particles
by number have a diameter less than 6 nanometers. Dry powder
compositions may include a solid fine powder diluent such as sugar
and are conveniently provided in a unit dose form.
[0430] Low boiling propellants generally include liquid propellants
having a boiling point of below 65.degree. F. at atmospheric
pressure. Generally the propellant may constitute 50 to 99.9% (w/w)
of the composition, and the active ingredient may constitute 0.1 to
20% (w/w) of the composition. The propellant may further comprise
additional ingredients such as a liquid non-ionic and/or solid
anionic surfactant and/or a solid diluent (which may have a
particle size of the same order as particles comprising the active
ingredient).
[0431] Pharmaceutical compositions described herein formulated for
pulmonary delivery may provide the active ingredient in the form of
droplets of a solution and/or suspension. Such formulations can be
prepared, packaged, and/or sold as aqueous and/or dilute alcoholic
solutions and/or suspensions, optionally sterile, comprising the
active ingredient, and may conveniently be administered using any
nebulization and/or atomization device. Such formulations may
further comprise one or more additional ingredients including, but
not limited to, a flavoring agent such as saccharin sodium, a
volatile oil, a buffering agent, a surface active agent, and/or a
preservative such as methylhydroxybenzoate. The droplets provided
by this route of administration may have an average diameter in the
range from about 0.1 to about 200 nanometers.
[0432] Formulations described herein as being useful for pulmonary
delivery are useful for intranasal delivery of a pharmaceutical
composition described herein. Another formulation suitable for
intranasal administration is a coarse powder comprising the active
ingredient and having an average particle from about 0.2 to 500
micrometers. Such a formulation is administered by rapid inhalation
through the nasal passage from a container of the powder held close
to the nares.
[0433] Formulations for nasal administration may, for example,
comprise from about as little as 0.1% (w/w) to as much as 100%
(w/w) of the active ingredient, and may comprise one or more of the
additional ingredients described herein. A pharmaceutical
composition described herein can be prepared, packaged, and/or sold
in a formulation for buccal administration. Such formulations may,

(w/w) active ingredient, the balance comprising an orally
dissolvable and/or degradable composition and, optionally, one or
more of the additional ingredients described herein. Alternately,
formulations for buccal administration may comprise a powder and/or
an aerosolized and/or atomized solution and/or suspension
comprising the active ingredient. Such powdered, aerosolized,
and/or aerosolized formulations, when dispersed, may have an
average particle and/or droplet size in the range from about 0.1 to
about 200 nanometers, and may further comprise one or more of the
additional ingredients described herein.
[0434] A pharmaceutical composition described herein can be
prepared, packaged, and/or sold in a formulation for ophthalmic
administration. Such formulations may, for example, be in the form
of eye drops including, for example, be in the form of eye drops
including, for example, a 0.1-a 0.1/1.0% (w/w) solution and/or
suspension of the active ingredient in an aqueous or oily liquid
carrier or excipient. Such drops may further comprise buffering
agents, salts, and/or one or more other of the additional
ingredients described herein. Other opthalmically-administrable
formulations which are useful include those which comprise the
active ingredient in microcrystalline form and/or in a liposomal
preparation. Ear drops and/or eye drops are also contemplated as
being within the scope of this disclosure.

Methods of Treatment and Use
[0450] Compounds described herein (e.g., compounds of Formula (I),
(II), (III), (IV), (V), and (VI)) have been found to bind
bromodomain-containing proteins. In certain embodiments, the
compounds described herein bind to a bromodomain-containing
protein. Without wishing to be bound by any particular theory, the
compounds described herein are thought to bind in a pocket of a
bromodomain of a bromodomain-containing protein. In certain
embodiments, the compounds described herein are thought to
simultaneously bind in pockets of two different bromodomains of a
bromodomain-containing protein. In certain embodiments, the
compounds described herein bind in the binding pocket of the
bromodomain by mimicking an acetyl-lysine residue of a second
protein (e.g., a histone).
[0451] In certain embodiments, the compounds described herein
non-covalently bind to the bromodomain-containing protein. In
certain embodiments, the compounds described herein reversibly bind
to the bromodomain-containing protein. In certain embodiments, the
compounds described herein inhibit the activity (e.g., aberrant
activity, increased activity) of a bromodomain-containing protein.
In certain embodiments, the compounds described herein inhibit the
activity (e.g., aberrant activity, increased activity) of a
bromodomain. In certain embodiments, the activity of a bromodomain
is the ability of the bromodomain to bind an acetylated lysine
residue (e.g., an acetylated lysine residue on the N-terminal tails
of histones), which may be part of another protein or peptide
(e.g., histone). In certain embodiments, the compounds described
herein specifically bind to a bromodomain-containing protein (e.g.,
bind to a bromodomain-containing protein with a higher binding
affinity than to a different bromodomain-containing protein and/or
to a protein that is not a bromodomain-containing protein). In
certain embodiments, the compounds described herein specifically
bind to a bromodomain of a bromodomain-containing protein (e.g.,
bind to a bromodomain of a bromodomain-containing protein with a
higher binding affinity than to a non-bromodomain of the
bromodomain-containing protein). In certain embodiments, the
compounds described herein non-specifically bind to a
bromodomain-containing protein (e.g., bind to a bromodomain of the
bromodomain-containing protein). In certain embodiments, the
compounds described herein reduce transcriptional elongation. In
certain embodiments, the compounds described herein disrupt the
subcellular localization of a bromodomain-containing protein. In
certain embodiments, the compounds described herein reduce
chromatin binding. In certain embodiments, the compounds described
herein inhibit the formation of chromatin by reducing the binding
of a protein (e.g., histone) to a DNA. In certain embodiments, the
compounds described herein inhibit the binding of Histone H4 Kac
peptide to a bromodomain of a bromodomain-containing protein. In
certain embodiments, the compounds described herein form one or
more hydrogen bonds with an evolutionarily conserved asparagine in
a bromodomain of a bromodomain-containing protein. In certain
embodiments, the asparagine is Asn140 in BRD4(1) and Asn429 in
BRD2(2). In certain embodiments, the bromodomain-containing protein
is BRD4 or BRD2; and the asparagine is Asn140 in BRD4(1) and Asn429
in BRD2(2). In certain embodiments, the compounds described herein
bind competitively with chromatin to a bromodomain in a cellular
environment. It is thus expected that the compounds described
herein may be useful in the treatment of a disease associated with
the activity a bromodomain-containing protein (e.g., a
proliferative disease).

EXAMPLES
[0495] These and other aspects of the present invention will be
further appreciated upon consideration of the following Examples,
which are intended to illustrate certain particular embodiments of
the invention but are not intended to limit its scope, as defined
by the claims.
Potent and Selective Bivalent Inhibitors of BET Family
Bromodomains
[0496] Bivalent inhibitors of BRD4 were designed, prepared, and
evaluated. The prior high-resolution structure of JQ1 bound to BD1
and BD2 (see, e.g., Filippakopoulos, P. et al. Nature 2010, 468,
1067-1073), and internal structure-activity relationship (SAR)
guidance, supports chemical substitution of the bulky t-butyl ester
functional group at C6 on the diazepine ring and substitution of
the methyl moiety at C2 on the thiophene ring, as both are
positioned toward solvent (FIG. 1b). As the BD1 and BD2
bromodomains are separated by a 280 residue linker region (FIG.
1c), and as binding may be intramolecular or intermolecular, the
chemical spacer between monomeric ligands was considered as a
variable for focused library synthesis. As limited biochemical data
are available on full-length BRD4, owing to challenges in active
protein preparation, the mode of linker attachment to monomeric
ligands was further considered in index library design. Three
series of dimeric molecules were first prepared, defined by
conjugation of a variably spaced polyethylene glycol (PEG) linker
to either the C6 or C2 positions, hereafter referred to as (6+6),
(2+2), and (6+2) (FIG. 1d).
[0497] First synthesized were (6+6) and (2+2) homodimers with a
minimal PEG spacer (FIGS. 2a and 2b). These compounds were compared
to control ligands in biochemical and cell-based assays of direct
BRD4 inhibition. To assess competitive binding with JQ1 to the BET
bromodomains, a luminescence homogeneous, nanomaterial-based
proximity assay was adapted (AlphaScreen.TM.) for BRD4(1) as the
primary screening method (see, e.g., McKeown, M. R. et al. Journal
of Medicinal Chemistry 2014, 57, 9019-9027; Roberts, J. M. &
Bradner, J. E. Current protocols in chemical biology 2015, 7,
263-278). For the synthesis of (2+2) homodimers, the methyl ester
analog of JQ1 (MS417, FIG. 1a) was adopted as an alternative
scaffold. In this assay system, the active (S)-enantiomer of JQ1
exhibited an IC.sub.50 of 21 nM (FIG. 6). In contrast, the
IC.sub.50 for the inactive (R)-enantiomer was >5 .TM.. Growth
effects of BRD4 inhibition were evaluated using BRD4-rearranged
carcinoma cells (so-called NUT midline carcinoma; NMC797) and acute
myeloid leukemia (AML) cell lines (MV4;11). (S)-JQ1 attenuates
proliferation of each cell line with IC.sub.50 values of 69 and 72
nM, respectively. MS417 showed similar levels of inhibition in both
AlphaScreen.TM. andin cells (FIG. 1a).
[0498] The (6+6) homodimer which has a PEG1 linker (hereafter
referred to as (6+6)-PEG1) did not show improved activity in either
the biochemical or cellular assays (FIG. 2a). Interestingly, the
(2+2) homodimer, (2+2)-PEG1 had a 20-fold increase in biochemical
potency (IC.sub.50=1.17 nM) (FIG. 2b). However, this effect was not
properly reflected in cellular activity, perhaps because of
decreased permeability arising from two appending ester moieties.
In order to overcome these challenges, focus was turned to (6+2)
heterodimers with various PEG linker lengths. These molecules
feature a single C6 position ester (FIG. 3a). Notably, all of the
(6+2) heterodimers we synthesized showed profound improvements in
potency (single-digit to sub-nanomolar IC.sub.50 values) in
biochemical assays (FIG. 7). Similar results were obtained for
another BET family protein BRDT(1) (FIG. 3c). Importantly, the
increased biochemical potency was maintained in cellular assays
(IC.sub.50s=0.22-2.6 nM). To rule out non-specific assay
interference from the compounds (e.g., aggregation), all of the
(6+2)-PEG1 diastereomers were synthesized (FIG. 3b-3d) (see, e.g.,
Dahlin, J. L. et al. Journal of medicinal chemistry 2015, 58,
2091-2113). Only the homo-combination of active (S)-enantiomers of
JQ1 ((6S+2S)-PEG1) retained single-digit to sub-nanomolar activity
in both the biochemical and cellular assays, while the homodimer of
inactive (R)-JQ1 ((6R+2R)-PEG1) showed much weaker activity
(IC.sub.50=5,956 nM by AlphaScreen.TM.). The hetero-combinations of
(S)- and (R)-JQ1 ((6S+2R)-PEG1 and (6R+2S)-PEG1) retained almost
the same level of activity as JQ1 in biochemical assays
(IC.sub.50=59 and 103 nM, respectively), suggesting a capacity for
linker conjugation at either the C2 or C6 positions. Together,
these data support dramatic enhancement of BRD4 binding by bivalent
inhibitors, in biochemical and cellular assays.
[0499] To further profile bivalent inhibitors, fluorescent
polarization (FP) and phage-based, multiplexed bromodomain
displacement assays (BROMOscan.TM., DiscoveRx) were utilized. All
analogs showed a similar tendency in the FP assay (FIG. 3c), with
somewhat increased sensitivity of the BROMOscan.TM. assay to JQ1
compared to AlphaScreen.TM. (BROMOscan.TM., K.sub.d=8.0 nM;
AlphaScreen.TM., IC.sub.50=20.9 nM for BRD4(1)). This tendency was
more pronounced for (6S+2S)-PEG1 (FIG. 3d). The compound exhibited
picomolar displacement of phage expressing BRD4(1), BRD4(2), a
tandem bromodomain construct (BRD4(1,2)), and full length protein
(BRD4(full)). These dramatic increases in activities were confirmed
to be selective for the BET family using a panel of 32
phage-displayed bromodomains (Table Si). The (6S+2S)-PEG1 compound
did not show significant binding to non-BET family bromodomains at
higher concentrations (K.sub.d=2.5 M for CBP, 5.0 M for EP300, 9.9
.mu.M for WDR9(2), >10 M for others). The relative selectivity
of the JQ1 scaffold is reflected in this JQ1 dimer.
[0500] To validate bivalent BET inhibition using an orthogonal
chemical scaffold, the more recently reported isoxazole BET
inhibitor, IBET-151, was adapted to a homodimeric strategy (see,
e.g., Dawson, M. A. et al. Nature 2011, 478, 529-533). IBET-151
exhibits comparable performance to JQ1 in biochemical and cellular
assays (FIG. 6). Guided by the reported co-crystal structure of
IBET-151 bound to BRD4(1) (PDB: 3ZYU), the isoxazole ring binds to
the conserved asparagine, while an amino moiety within the cyclic
urea is faced toward a solvent exposed region. Hetero- and
homodimeric combinations of I-BET151 and JQ1 were synthesized again
using a series of PEG linkers (FIG. 8). Impressively, a 5-fold
increase in biochemical inhibition was observed for some
combinations.
Bivalent Inhibitors Bind to the Two Kac Binding Sites of BET Family
Bromodomains
[0501] To determine whether the observed increase in potency is
mediated by bivalent interaction with two discrete bromodomains,
size-exclusion chromatography (SEC) and isothermal titration
calorimetry (ITC) was employed. SEC showed that the active
(6S+2S)-PEG1 molecule completely shifted the BRD4(1) monomeric peak
to a more slowly migrating dimeric peak when added in a 1:2 ratio
to the protein, whereas excess JQ1 and the inactive (6R+2R)-PEG1
molecule failed to shift the monomer peak (FIG. 4a).
Experimentally, overt signs of protein aggregation were not
observed. ITC experiments revealed that JQ1 and (6S+2S)-PEG1 bound
with a similar range of K.sub.d values (40 and 17 nM, respectively)
to isolated BRD4(1), as expected. However, the stoichiometry of
binding was divergent. JQ1 bound to BRD4(1) in a 1:1 ratio, whereas
(6S+2S)-PEG1 bound to BRD4(1) in a 1:2 ratio (FIG. 4b). Together,
these findings support the possibility of an avidity effect via
dimerization of individual BET bromodomains.
Bivalent Inhibitors Induce Growth Arrest in AML Cells Associated
with MYC Downregulation and HEXIM1 Upregulation
[0502] Next was assessed the cellular consequences of bivalent BET
inhibitors in a series of cancer cell assays, previously
credentialed for BRD4-specific biology using JQ1. To assess if cell
growth inhibition by (2S+6S)-PEG1 is mediated through
downregulation of MYC transcription as observed with JQ1,
expression levels of MYC and HEXIM1 after compound treatment were
measured by immunoblot. Within two hours of treatment with
(2S+6S)-PEG1 in MV4;11 cells, MYC was downregulated in a
concentration-dependent manner at concentrations as low as 10 nM
(FIG. 4c). This effect was time-dependent and reversible (FIG. 4d),
with a maximum effect achieved at 2 hours. Consistent with an
inhibitory effect on transcriptional elongation, upregulation of
the compensatory negative elongation factor HEXIM1 was observed at
later time points (4-24 hours). Together, these data support
on-target BRD4 activity in cells (see, e.g., Chaidos, A. et al.
Blood 2014, 123, 697-705; Bartholomeeusen, K et al. The Journal of
biological chemistry 2012, 287, 36609-36616). Recently reported
were highly potent compounds capable of degrading BET bromodomain
proteins, via chemical conjugation of E3 ligase-recruiting
phthalimides. To rule out enhanced potency via BET degradation,
immunoblots following compound treatment were performed (see, e.g.,
Winter, G. E. et al. Science (New York, N.Y.) 2015, 348, 1376-1381,
doi:10.1126/science.aab1433). No effect on protein stability was
observed, suggesting that this effect is not likely due to
oligomerization and subsequent degradation of BRD4 in cells. These
findings support that the cell growth inhibition by (2S+6S)-PEG1
was associated with specific BRD4 engagement.
MT1: A Bivalent Chemical Probe of BET Bromodomains
[0503] Although JQ1 has acceptable pharmacokinetic (PK) properties
for animal studies, the in vivo plasma half-life of the heterodimer
(2S+6S) was short, perhaps suggesting extensive metabolization of
the newly introduced linker section (FIG. 9a and FIG. 9b) (see,
e.g., Matzuk, M. M. et al. Cell 2012, 150, 673-684). Therefore, a
biostable derivative was sought to support use as a chemical probe
in vivo. During linker optimization, it was clear that the
homodimer (6S+6S) derivative with a long PEG7 linker (hereafter
referred to as MT1) has comparable activity (IC.sub.50=3.09 nM for
BRD4(1)) to the heterodimer molecules explored earlier, but
improved PK properties (FIG. 5a and FIG. 10a). MT1 does not possess
ester moieties, which are prone to metabolization. Also note that
the heterodimer (6S+2S) with a short "PEG0" (ethylene diamine)
linker has comparable PK properties to MT1 (FIG. 10b). The
biochemical activity of MT1 was translated well in cellular
activities (FIG. 5e), encouraging us to further profile the
molecule. MT1 exhibits few off-target effects on cellular receptors
and ion channels, among more than 50 tested. As with the parent
scaffold JQ1, only partial inhibition of binding of a [Nleu-10]-NKA
radioligand agonist for the neurokinin NK2 receptor was observed
(FIG. 15 and FIG. 21) (see, e.g., Filippakopoulos, P. et al. Nature
2010, 468, 1067-1073). These data led to further profiling of
MT1.
[0504] To assess whether MT1 dimerizes monomeric BET bromodomains,
an AlphaScreen.TM. assay was adapted to estimate ligand-induced
proximity of two differentially tagged BRD4(1) constructs.
Luminescence transfer was observed between GSH-donor beads and
nickel-acceptor beads when GST-BRD4(1) and His-BRD4(1) constructs
were introduced with MT1. Increase in signal over baseline levels
was observed in the sub-micromolar range (FIG. 5b). The luminescent
signal deteriorated at higher concentrations, characteristic of the
Hook effect seen with multivalent inhibitors (see, e.g., Dutta Roy,
R. & Stefan, M. I. bioRxiv 2015).
[0505] To establish the binding mode of MT1, co-crystal structures
of the ligand in complex with purified, recombinant BRD4(1) and
BRD4(2) were solved. A cocrystal structure of BRD4(2) was
successfully obtained when excess MT1 was added (FIG. 5c, FIG. 5d,
and FIG. 17). For data collection and refinement statistics see
FIG. 22. A similarly high concentration of MT1 was not compatible
with BRD4(1) crystallization. The determined high-resolution
structure clearly revealed one molecule of MT1 simultaneously
recognizing two bromodomains of BRD4(2) (FIG. 5c). MT1 binding
established a newly created hydrophobic pocket between the two
bromodomain monomers (FIG. 5d). Overall, the binding mode of each
warhead is very close to that of JQ1 in BRD4(1) (see, e.g.,
Filippakopoulos, P. et al. Nature 2010, 468, 1067-1073). Each
triazole ring formed a hydrogen bond with the evolutionarily
conserved asparagine and exhibited great shape complementarity with
the Kac binding site, occupying the entire binding pocket. Again,
these findings support a bromodomain dimerization-based avidity
effect for MT1 efficacy.
[0506] To address whether MT1 binds to BRD4 in an intramolecular or
intermolecular fashion SEC was employed once again, this time using
tandem bromodomain constructs that are either wild-type or have a
point mutation at one of the key conserved asparagine residues in
each bromodomain binding pocket (N.sub.140A in BRD4(1) and
N.sub.433A in BRD4(2)), rendering them unable to bind JQ1. Complete
dimerization was observed for the second bromodomain mutant
(BRD4(1,2.sup.MUT)) when half an equivalence of MT1 was added in
contrast to the absence of dimerization when the wild-type
BRD4(1,2) protein was used. Likewise partial dimerization was
observed for the BRD4(1.sup.MUT,2) construct (FIG. 5h). These
results support a model whereby MT1 binds to tandem bromodomains in
an intramolecular fashion and that both BRD4(1) and BRD4(2) are
directly involved in this binding event.
[0507] To establish target engagement of MT1 in a cellular context
we performed a cellular thermal shift assay (CETSA) (see, e.g.,
Martinez Molina, D. et al. Science 2013, 341, 84-87,
doi:10.1126/science.1233606). In the CETSA assay cells are treated
with vehicle or drug, heated to denature and precipitate proteins,
and lysed. Cellular debris and aggregates are separated from the
soluble protein fraction by centrifugation. Whereas unbound
proteins denature and precipitate at elevated temperatures,
ligand-bound proteins remain in solution. Stabilized protein in the
supernatant was measured by quantitative immunoblotting. Both JQ1
and MT1 stabilized BRD2, 3 and 4 in a concentration dependent
manner although MT1 was able to bind and stabilize BET proteins at
lower concentrations (FIG. 5i and FIG. 18). These results
effectively demonstrate MT1 cellular target engagement of BET
family proteins.
[0508] Finally, the effect of MT1 on cancer cell viability was
assessed. Significant apoptosis was observed by caspase-3 and PARP
cleavage after treatment with MT1 (FIG. 5f). These cellular events
followed after HEXIM1 upregulation and MYC downregulation. Early
and late apoptosis were assessed with annexin-V and propidium
iodide staining to compare apoptosis induction between MT1 and JQ1
(FIG. 5g and FIG. 11). Importantly, MT1 induced a greater degree of
apoptosis at 10-fold lower concentrations than JQ1.
[0509] MT1 possesses all desirable qualities of a chemical probe
and/or therapeutic agent, such as high target potency in
homogeneous and cellular assays, a well-characterized profile of
selectivity, and synthetic accessibility (for synthetic schemes of
MT1 see FIG. 23) (see, e.g., Arrowsmith, C. H. et al. Nature
chemical biology 2015, 11, 536-541, doi:10.1038/nchembio.1867).
[0510] Antitumor Efficacy of MT1 in Xenograft Models of
Leukemia
[0511] To determine whether MT1 could attenuate the growth of
BRD4-dependent leukemia as a single agent in vivo, an aggressive
disseminated leukemia model was selected (mCherry.sup.+,
Luciferase.sup.+, MV4;11) and treated animals with established
disease using equimolar (44.2 .mu.mol/kg) and half an equivalence
(22.1 .mu.mol/kg) of MT1 compared to JQ1 for 14 days. During the
study, leukemic burden was monitored by non-invasive
bioluminescence imaging. Even half an equivalence of MT1
significantly reduced leukemic burden over the course of the study
compared to either vehicle or JQ1 (FIG. 13a). Post-mortem analysis
of leukemic burden in bone marrow by FACS also revealed
significantly decreased mCherry.sup.+ disease with MT1
administration at 22.1 .mu.g/kg (FIG. 13b).
[0512] We performed a second study to assess the survival advantage
endowed by MT1 over JQ1 or vehicle using a similar xenograft model
where mice were treated with equimolar concentrations of JQ1 and
MT1 for 12 days (44.2 .mu.mol/kg). After a two-day drug holiday we
continued treatment for another 5 days. At this high dose of drug,
two mice (of 11) in the MT1 group needed to be sacrificed due to
emaciation from drug toxicity. Drug administration was stopped
after this point and survival of the remaining mice was monitored.
It is notable that those mice that had lost weight on MT1 recovered
body weight after drug was withdrawn (FIG. 19). As previously,
disease monitored by bioluminescence was significantly reduced with
MT1 treatment compared to JQ1 (FIG. 13c, FIG. 13d). Importantly MT1
significantly increased overall survival compared to vehicle or JQ1
treated mice (FIG. 13e).
[0513] A need exists for the development of qualified probes of
transcriptional and epigenomic proteins. Among these compelling
targets are epigenetic reader proteins, which function through
protein-protein interactions with post-translationally modified
chromatin and transcription factors. Inhibitors of individual
protein-protein interactions are historically difficult to realize,
but the epigenetic reader proteins commonly possess multivalent
recognition modules.
[0514] A structural hypothesis was tested regarding multivalent
recognition of BET family bromodomain proteins by bivalent organic
ligands. Heterodimeric derivatives showed greatly improved activity
both biochemically and in cells with little linker length
dependence. Improved activity of heterodimeric compounds is likely
due to their ability to dimerize bromodomains as evidenced by SEC,
ITC, and nanomaterial-based proximity assays. These bivalent
inhibitors have pronounced efficacy and rapid kinetic
downregulation of MYC in cultivated human cancer cells,
establishing a rationale for drug-like derivatives to be advanced
to human clinical investigation. Indeed, the best optimized
bivalent inhibitor MT1 exhibits a 400-fold improvement in activity
in AML compared to JQ1, and highly prolonged exposure in vivo. It
is noteworthy that improvements of metabolic stability and PK
properties are accomplished by varying the linker length and the
attachment points although MT1 is rather large as a canonical small
molecule inhibitor (molecular weight 1134 Da). This chemical
modification has led to a selective and highly potent chemical
probe that out-performs JQ1 in an in vivo leukemia model.
General Methods
Cell Culture
[0515] MV4;11 cells were purchased from ATCC, and NMC 797 cells
were a kind gift from Dr. Christopher French (Brigham and Women's
Hospital), described previously (see, e.g., French, C. A. et al. J
Clin Oncol 2004, 22, 4135-4139, doi:10.1200/JCO.2004.02.107). Cells
were cultured at 37.degree. C. with 5% CO.sub.2 in either DMEM
(NMC797) or RPMI1640 (MV4;11) supplemented with 10% FBS (Sigma),
100 U/mL penicillin, 100 .mu.g/mL streptomycin, and 2 mM glutamine
(Gibco). Cells tested negative for mycoplasma using the
MycoAlert.TM. kit (Lonza). None of the utilized cell lines are
among those that are commonly misidentified as listed by ICLAC.
BRD4(1) and BRDT(1) AlphaScreen.TM.
[0516] Assays were performed with minimal modifications from the
manufacturer's protocol (PerkinElmer, USA). All reagents were
diluted in AlphaScreen.TM. buffer (50 mM HEPES, 150 mM NaCl, 0.1%
w/v BSA, 0.01% w/v Tween20, pH 7.5) and allowed to equilibrate to
room temperature prior to addition to plates. After addition of
Alpha beads to master solutions all subsequent steps were performed
under low light conditions. A 2.times. solution of components with
final concentrations of His-BRD4(1) or His-BRDT(1) (see protein
expression section) at 40 nM, Ni-coated Acceptor Bead at 10
.mu.g/ml, and 20 nM biotinylated-JQ1 was added in 10 .mu.L to
384-well plates (AlphaPlate-384, PerkinElmer) (see, e.g., Anders,
L. et al. Nature biotechnology 2014, 32, 92-96). Plates were spun
down at 150.times.g, 100 nL of compound in DMSO from stock plates
were added by pin transfer using a Janus Workstation (PerkinElmer).
The streptavidin-coated donor beads (10 .mu.g/ml final) were added
as with previous in a 2.times., 10 .mu.L volume. Following this
addition, plates were sealed with foil to prevent light exposure
and evaporation. The plates were spun down again at 150.times.g.
Plates were incubated at room temperature for 1 hour and then read
on an Envision 2104 (PerkinElmer) using the manufacturer's
protocol.
BRD4(1) dimerization AlphaScreen.TM.
[0517] Assays were performed with minimal modifications from the
manufacturer's protocol (PerkinElmer, USA). All reagents were
diluted in AlphaScreen.TM. buffer (50 mM HEPES, 150 mM NaCl, 0.1%
w/v BSA, 0.01% w/v Tween20, pH 7.5) and allowed to equilibrate to
room temperature prior to addition to plates. After addition of
Alpha beads to master solutions all subsequent steps were performed
under low light conditions. A 2.times. solution of components with
final concentrations of His-BRD4(1) (see protein expression) and
GST-BRD4(1) (BPS Biosciences) at 40 nM was added in 10 .mu.L to
384-well plates (AlphaPlate-384, PerkinElmer). Plates were spun
down at 150.times.g, 100 nL of compound in DMSO from stock plates
were added by pin transfer using a Janus Workstation (PerkinElmer).
Plates were allowed to incubate for 30 minutes before addition of
Ni-coated Acceptor and GSH-coated Donor Beads as with previous in a
2.times., 10 .mu.L volume. Following this addition, plates were
sealed with foil to prevent light exposure and evaporation. The
plates were spun down again at 150.times.g. Plates were incubated
at room temperature for 30 minutes and then read on an Envision
2104 (PerkinElmer) using the manufacturer's protocol. Data was
analyzed using GraphPad PRISM v6 and IC.sub.50 values were
determined using the `log(inhibitor) vs normalized
response-variable slope` analysis module.
BRD4(1) Fluorescence Polarization Assay
[0518] In 384-well black plates (Nunc), 250 nM His-BRD4(1) (see
protein expression section) and 20 nM JQ1-FITC were diluted in 20
uL assay buffer (50 mM HEPES, 150 mM NaCl, 0.01% w/v Tween20, pH
7.5) containing competitor compound or DMSO. Following 30 min
incubation at RT, fluorescence polarization (mP) was measured using
Envision 2104 Multilabel Reader (FP FITC dual optical module;
Excitation: 480 nm, Emission: 535 nm for both S- and P-channels).
Normalized mP values were calculated by setting the average
background (no enzyme wells) to 0% the average DMSO wells to 100%
activity. Standard deviations were determined from four replicate
measurements for each compound concentration. Data were analyzed
and plotted using GraphPad PRISM v6 and IC.sub.50 values were
determined using the `log(inhibitor) vs normalized
response-variable slope` analysis module.
Analysis of Cell Viability by ATPLite
[0519] Cells were plated at 1000 cells/well in 50 .mu.L/well of
media in 384 well white culture plates (Thermo). NMC797 cells were
allowed to adhere overnight before adding 100 .mu.L of compound in
DMSO from compound stock plates using a Janus Workstation pin tool
(PerkinElmer, USA). After addition of compound, plates were
incubated for 72 hours at 37.degree. C. Cell viability was read out
using the ATPlite kit (PerkinElmer). Plates were brought to room
temperature prior to reagent addition. Lyophilized powder was
resuspended in lysis buffer and diluted 1:2 with DI water. 20 .mu.L
of this solution was added to each well and plates were incubated
for 15 min at room temperature before signal was read on an
Envision 2104 plate reader (Perkin Elmer).
Cellular Thermal Shift Assay (CETSA)
[0520] Compound or DMSO was incubated with 4.times.10.sup.6 MV411
cells for 1 hr at 37.degree. C. Cells were put on ice and washed
with PBS and transferred to PCR tubes. Supernatant was aspirated to
leave .about.5 .mu.l in each tube and then cells were heat shocked
in a thermocycler at 48.5.degree. C. for 3 min to denature
proteins. Cells were then allowed to cool at RT for 3 min and then
resuspended in 35 .mu.l lysis buffer (50 mM Tris-HCl pH 7.5, 5%
glycerol, 100 mM NaCl, 1.5 mM MgCl, 0.2% NP-40+protease inhibitor
cocktail (Halt)) and freeze-thawed 3 times with liquid nitrogen to
lyse cells. Lysates were then spun at 20,000.times.g for 20 min to
clarify and pellet aggregated protein. Supernatant was boiled with
LDS and split into three samples for immunoblotting. Bands were
quantified using Image Studio.TM. software and plotted using
GraphPad PRISM v6 as triplicate means.+-.SEM.
Xenograft Experiments
[0521] MV4;11 human leukemia cells (mCherry+ and Luciferase+) were
tail-vein injected into immunocompromised (NOD.Cg-Prkdc.sup.scid
Il2rg.sup.tm1Wjl/SzJ, NSG) 8 week old female mice (2.times.10e6
cells/animal) purchased from The Jackson Laboratory (005557). Cells
tested negative for mycoplasma and rodent infectious agents at
Charles River Laboratories (Mouse Comprehensive Panel).
Luminescence was utilized to monitor engraftment (evident 7 days
after injection), at which point mice were randomly assigned into
four cohorts that received MT1 at 44.2 .mu.mol/kg (n=8), MT1 at
22.1 .mu.mol/kg (n=9), JQ1 at 44.2 .mu.mol/kg (n=8) or vehicle
(n=8) formulated in a 10% captisol, 10% DMSO solution in water.
Mice that failed to engraft were excluded from the study. Each
group was dosed once daily for 14 days (day 7-21) and
bioluminescence was monitored weekly at 7, 14 and 21 days post
injection. At day 21, mice were sacrificed, bone marrow was
extracted from both femurs of each mouse and leukemic burden was
determined by measuring % mcherry.sup.+ cells with an LSRFortessa
X-20 flow cytometer (FIG. 6b).
[0522] A second experiment was performed as above using 12 week old
mice with engraftment evident at 17 days after injection, at which
point mice were randomly assigned into three cohorts that received
MT1 (n=11), JQ1 (n=11) or vehicle (n=11) treatment once daily for
12 subsequent days. A drug holiday was given for 2 days (day
29-30), Treatment resumed for 5 more days (31-35) and then ended.
Mice were monitored and sacrificed when hind-limb paralysis was
evident or body weight dropped by 15%. Both agents were dosed at
equimolar concentrations of 44.2 .mu.mol/kg (50 mg/kg and 20.2
mg/kg for MT1 and JQ1, respectively).
Flow Cytometry
[0523] For analysis of apoptotic cells, cells were washed with
Annexin V binding buffer (140 mM NaCl, 10 mM HEPES, 2.5 mM
CaCl.sub.2), pH 7.4) and then stained with 250 ng/mL FITC-Annexin V
and 500 ng/mL propidium iodide in Annexin V binding buffer. All
centrifugation steps were performed at 400.times.g at 4.degree. C.
for 5 minutes. Flow cytometry analyses were performed on an
LSRFortessa X-20 flow cytometer (BD Biosciences) and all data
analyzed with FlowJo software (v0, Tree Star).
Immunoblotting
[0524] Cells were lysed with RIPA buffer supplemented with protease
inhibitor cocktail (Roche) and 0.1% benzonase (Novagen) on ice for
20 minutes. The lysates were spun at 20,000.times.g for 15 minutes
at 4.degree. C. and protein concentration was determined by a BCA
assay (Pierce). The following antibodies were used in this study:
BRD4 (Bethyl labs), c-MYC and actin (both Santa Cruz), HEXIM1,
PARP, cleaved caspase 3 (all Cell Signaling Technology). Blots were
imaged using fluorescence-labeled secondary antibodies (LI-COR) on
the OdysseyCLxImager (LI-COR).
Protein Expression and Purification
[0525] A construct of human BRD4 covering residues 44-168
(His-BRD4(1)) or 333-460 (His-BRD4(2)) in the pNIC28Bsa4 vector
(Addgene) was overexpressed in E. coli BL21 (DE3) in LB medium in
the presence of 50 mg/ml of kanamycin. Cells were grown at
37.degree. C. to an OD of 0.8, cooled to 17.degree. C., induced
with 500 M isopropyl-1-thio-D-galactopyranoside, incubated
overnight at 17.degree. C., collected by centrifugation, and stored
at -80.degree. C. For His-BRD4(1) cell pellets were sonicated in
buffer A (50 mM HEPES pH 7.4, 400 nM NaCl, 1 mM BME, 10 mM
imidazole) and for His-BRD4(2) cell pellets were sonicated in
buffer B (50 mM HEPES pH 7.5, 300 mM NaCl, 10% glycerol, 10 mM
imidazole, 3 mM BME) and the resulting lysate was centrifuged at
30,000.times.g for 30 min. Ni-NTA beads (Qiagen) were mixed with
lysate supernatant for 30 min and washed with buffer A or B. Beads
were transferred to an FPLC-compatible column and the bound protein
was washed with 15% buffer C (50 mM hepes pH 7.4, 400 nM NaCl, 1 mM
BME, 500 mM imidazole) or buffer D (50 mM HEPES pH 7.5, 300 mM
NaCl, 10% glycerol, 300 mM imidazole, and 3 mM BME) and eluted with
100% buffer C or D. His-BRD4(1) were dialyzed against 20 mM HEPES
pH 7.5, 150 mM NaCl, 1 mM BME and frozen at -80.degree. C. for use
in AlphaSceen.TM. and FP assays. For crystallography studies of
BRD4(2) TEV was added to the eluted protein and incubated at
4.degree. C. overnight. The sample was then passed through a
desalting column (26/10 column) pre-equilibrated with buffer B
without imidazole, and the eluted protein was subjected to a second
Ni-NTA step to remove the His-tag and TEV site. The eluent was
concentrated and passed through a Superdex 200 10/300 column (GE
healthcare) in a buffer containing 20 mM HEPES 7.5, 150 mM NaCl,
and 1 mM DTT. Fractions were pooled, concentrated to 14 mg/ml (BD1)
or 48 mg/ml (BD2), and frozen at -80.degree. C.
[0526] For BRD4(1) dimerization AlphaSceen.TM. assays a construct
of human BRD4 covering residues 2-170 (GST-BRD4(1)) in a gateway
compatible pgex-6p-1 vector (Amersham) was overexpressed in E. coli
BL21 (DE3) in LB medium in the presence of 50 mg/ml of
carbenicillin. Cells were grown at 37.degree. C. to an OD of 0.6,
induced with 500 .mu.M isopropyl-1-thio-D-galactopyranoside (IPTG),
incubated for 4 hr at 37.degree. C., collected by centrifugation,
and stored at -80.degree. C. Cell pellets were resuspended in
buffer E (50 mM HEPES pH 8.0, 300 mM NaCl, 10% glycerol) and then
lysozyme was added to a concentration of 0.33 mg/mL, and the pellet
incubated at RT for 30 minutes and then sonicated. The resulting
lysate was centrifuged at 30,000.times.g for 30 min. Supernatant
was added to 2 mL of packed Glutathione Sepharose.RTM. 4B (GE
Healthcare, 17-0756-01) beads and incubated overnight at 4.degree.
C. and then purified in batch mode with buffer E+16 mM glutathione.
Batches were pooled and then dialyzed against buffer E to get rid
of contaminating glutathione and frozen at -80.degree. C. at a
concentration of 3.23 mg/ml.
[0527] His-BRDT(1) was obtained as described previously (see, e.g.,
Filippakopoulos, P. et al. Selective inhibition of BET
bromodomains. Nature 2010, 468, 1067-1073). An SDS page gel showing
the purity of each recombinant protein can be found in FIG. 20.
Crystallization, Data Collection and Structure Determination
[0528] A half equivalence of MT1 (10 mM in DMSO) was mixed with 500
.mu.M protein and crystallized by sitting-drop vapor diffusion at
20.degree. C. in the following crystallization buffer: 2 M NH4SO4
and 0.1 M BisTris pH 5.5. Crystals were transferred briefly into
crystallization buffer containing 25% glycerol prior to
flash-freezing in liquid nitrogen. Diffraction data from complex
crystals were collected at beamline 24ID-E of the NE-CAT at the
Advanced Photon Source (Argonne National Laboratory). Data sets
were integrated and scaled using XDS (see, e.g., Kabsch, W. Acta
crystallographica. Section D, Biological crystallography 2010, 66,
133-144). Structures were solved by molecular replacement using the
program Phaser (see, e.g., McCoy, A. J. et al. Phaser
crystallographic software. J Appl Crystallogr 2007, 40, 658-674,
doi:10.1107/50021889807021206). The ligand was positioned and
preliminarily refined using Buster and Rhofit (see, e.g., Smart, O.
S. et al. Acta Crystallogr D Biol Crystallogr 2012, 68, 368-380,
doi:10.1107/50907444911056058). Iterative manual model building and
refinement using Phenix and Coot led to a model with excellent
statistics (see, e.g., Adams, P. D. et al. Acta Crystallogr D Biol
Crystallogr 2010, 66, 213-221, doi:10.1107/S0907444909052925;
Emsley, P. & Cowtan, K. Acta Crystallogr D Biol Crystallogr
2004, 60, 2126-2132, doi:10.1107/S0907444904019158). The solved
structure has been submitted to the PDB as 5JWM.
Size-Exclusion Chromatography
[0529] The oligomeric state of the BRD4(1) in solution was analyzed
by gel filtration in a buffer containing 20 mM Hepes pH 7.5, 150 mM
NaCl using a Superdex 200 10/300GL column (GE Healthcare)
calibrated with globular proteins of known molecular weight (GE
Healthcare, 28-4038-41/42). Protein (50 .mu.M) and ligands
(6S+2S)-PEG1 (25 .mu.M), (6R+2R)-PEG1 (100 .mu.M), JQ1 (100 M) or
DMSO were mixed and incubated at 20.degree. C. for 20 min before
injection. Eluting peaks were monitored using ultraviolet
absorbance at 280 nm. BRD4(1,2) and domain mutants
BRD4(1.sup.MUT,2) and BRD4(1,2.sup.MUT) Corresponding to the
N.sub.140A and N.sub.433A mutants respectively were analyzed using
the same method but 42 .mu.M of protein was used with a half
equivalence of MT1.
Isothermal Titration Calorimetry
[0530] Experiments were carried out on an Auto-ITC200 titration
microcalorimeter (Malvern Instruments). All experiments were
carried out at 25.degree. C. while stirring at 1000 rpm, in ITC
buffer (50 mM HEPES pH 7.4 at 25.degree. C., 150 mM NaCl). The
microsyringe was loaded with a solution of the ligand sample. All
titrations were conducted using an initial injection of 0.4 .mu.l
followed by 19 identical injections of 2.0 .mu.l with a duration of
4 sec (per injection) and a spacing of 120 sec between injections.
The heat of dilution was determined by independent titrations
(ligand into buffer) and was subtracted from the experimental data.
The collected data were analyzed in the MicroCal.TM. Origin
software supplied with the instrument to yield enthalpies of
binding (AH) and binding constants (KB) as previously described by
Wiseman and coworkers (see, e.g., Wiseman et al. Analytical
biochemistry 1989, 179, 131-137). Thermodynamic parameters were
calculated (.DELTA.G=.DELTA.H-T.DELTA.S=-RTlnKB, where .DELTA.G,
.DELTA.H and .DELTA.S are the changes in free energy, enthalpy and
entropy of binding respectively). In all cases a single binding
site model was employed.
Receptor Profiling Studies
[0531] Selectivity profiling (ExpresSProfile) was performed on MT1
at 1 .mu.M against 55 ligand receptors, ion channels, and transport
proteins by CEREP (Eurofins, Paris, France) using manufacturer's
protocols.
Statistics and Animal-Model Statements
[0532] For all experiments, number of replicates (n), center
values, error bars, and p-value cutoffs are described in the
respective Figure legends. Error bars are shown for all data points
with replicates as a measure of variation within each data group.
All t-tests performed were Welch's t-tests that allows for unequal
variance and distributions assumed to follow a Student's t
distribution. These assumptions are not contradicted by the data.
All t-tests were two-sided. No statistical methods were used to
predetermine sample size. The experiments were not randomized, and
the investigators were not blinded to allocation during experiments
and outcome assessment. Animal experiments were conducted following
protocol 13-053 approved by the Dana-Farber Cancer Institute Animal
Care and Use Committee and adherent to DFCI institutional
standards.
Synthetic Methods
General Procedure for the Synthesis of (6S+2S)-PEG Derivatives
[0533]
(S)-2-(4-(4-chlorophenyl)-2,3,9-trimethyl-6H-thieno[3,2-f][1,2,4]tr-
iazolo[4,3-a][1,4]diazepin-6-yl)acetic acid (CAS #202592-23-2) (40
mg, 0.1 mmol), corresponding mono-Boc-amino-PEG-amine (1.5 eq),
HATU (1.5 eq), and N,N-diisopropylethylamine (1.5 eq) were added to
DMF (0.1 M). The mixture was stirred for 4 hours at room
temperature. The mixture was diluted with EtOAc, washed with 1N
NaOH and brine, dried over Na.sub.2SO.sub.4, filtrated and
concentrated under reduced pressure. The residue was purified by
flash chromatography to give mono-amides (49 to 99%). The
mono-amide was dissolved into dichloromethane (0.5 M).
Trifluoroacetic acid (0.5 M) was added to the solution. The mixture
was stirred for 1 hour at room temperature. The mixture was diluted
with dichloromethane, washed with 1N NaOH, dried over
Na.sub.2SO.sub.4, filtrated and concentrated under reduced
pressure. The free amine was used for the next step without
purification. The free amine,
(S)-4-(4-chlorophenyl)-6-(2-methoxy-2-oxoethyl)-3,9-dimethyl-6H-thieno[3,-
2-f][1,2,4]triazolo[4,3-a][1,4]diazepine-2-carboxylic acid (CAS
#916493-82-8) (1.1 eq), HATU (1.5 eq), and
N,N-diisopropylethylamine (1.5 eq) were added to DMF (0.1 M). The
mixture was stirred for 4 hours at room temperature. The mixture
was diluted with ethyl acetate, washed with 1N NaOH and brine,
dried over Na.sub.2SO.sub.4, filtrated and concentrated under
reduced pressure. The residue was purified by flash chromatography
to give the titled compounds (50 to 81%, for 2 steps).

General Procedure for the Synthesis of 6S+IBET Derivatives
[0552] 1 I-BET151 (CAS #1300031-49-5) (42 mg, 0.1 mmol) was
dissolved to DMF (0.5 M). Sodium hydride (1.2 eq) was added to the
solution. The mixture was stirred for 30 minutes at room
temperature. Methyl bromoacetate (1.3 eq) was added to the mixture.
The mixture was stirred for 4 hours at room temperature. The
mixture was diluted with EtOAc, washed with water and brine, dried
over Na.sub.2SO.sub.4, filtrated and concentrated under reduced
pressure. The methyl ester was used for the next step without
purification. The methyl ester was dissolved to THF (0.5 M) and
methanol (0.5 M). 1N NaOH (4 eq) was added to the mixture. The
mixture was stirred for 1 hour at room temperature. The mixture was
diluted with EtOAc, washed with 1N HCl and brine, dried over
Na.sub.2SO.sub.4, filtrated and concentrated under reduced
pressure. The carboxylic acid was used for the next step without
purification. The carboxylic acid, corresponding
mono-Boc-amino-PEG-amine (1.5 eq), HATU (1.5 eq), and
N,N-diisopropylethylamine (1.5 eq) were added to DMF (0.1 M). The
mixture was stirred for 4 hours at room temperature. The mixture
was diluted with EtOAc, washed with 1N NaOH and brine, dried over
Na.sub.2SO.sub.4, filtrated and concentrated under reduced
pressure. The residue was purified by flash chromatography to give
mono-amide (54 to 88%, for 3 steps). The mono-amide was dissolved
into dichloromethane (0.5 M). Trifluoroacetic acid (0.5 M) was
added to the solution. The mixture was stirred for 1 hour at room
temperature. The mixture was diluted with dichloromethane, washed
with 1N NaOH, dried over Na.sub.2SO.sub.4, filtrated and
concentrated under reduced pressure. The amine was used for the
next step without purification. The amine,
(S)-4-(4-chlorophenyl)-6-(2-methoxy-2-oxoethyl)-3,9-dimethyl-6H-thieno[3,-
2-f][1,2,4]triazolo[4,3-a][1,4]diazepine-2-carboxylic acid (CAS
#916493-82-8) (1.1 eq), HATU (1.5 eq), and
N,N-diisopropylethylamine (1.5 eq) were added to DMF (0.1 M). The
mixture was stirred for 4 hours at room temperature. The mixture
was diluted with EtOAc, washed with 1N NaOH and brine, dried over
Na.sub.2SO.sub.4, filtrated and concentrated under reduced
pressure. The residue was purified by flash chromatography to give
the titled compounds (38 to 64%, for 2 steps).

EQUIVALENTS AND SCOPE
[0566] In the claims articles such as "a," "an," and "the" may mean
one or more than one unless indicated to the contrary or otherwise
evident from the context. Claims or descriptions that include "or"
between one or more members of a group are considered satisfied if
one, more than one, or all of the group members are present in,
employed in, or otherwise relevant to a given product or process
unless indicated to the contrary or otherwise evident from the
context. The invention includes embodiments in which exactly one
member of the group is present in, employed in, or otherwise
relevant to a given product or process. The invention includes
embodiments in which more than one, or all of the group members are
present in, employed in, or otherwise relevant to a given product
or process.
[0567] Furthermore, the invention encompasses all variations,
combinations, and permutations in which one or more limitations,
elements, clauses, and descriptive terms from one or more of the
listed claims is introduced into another claim. For example, any
claim that is dependent on another claim can be modified to include
one or more limitations found in any other claim that is dependent
on the same base claim. Where elements are presented as lists,
e.g., in Markush group format, each subgroup of the elements is
also disclosed, and any element(s) can be removed from the group.
It should it be understood that, in general, where the invention,
or aspects of the invention, is/are referred to as comprising
particular elements and/or features, certain embodiments of the
invention or aspects of the invention consist, or consist
essentially of, such elements and/or features. For purposes of
simplicity, those embodiments have not been specifically set forth
in haec verba herein. It is also noted that the terms "comprising"
and "containing" are intended to be open and permits the inclusion
of additional elements or steps. Where ranges are given, endpoints
are included. Furthermore, unless otherwise indicated or otherwise
evident from the context and understanding of one of ordinary skill
in the art, values that are expressed as ranges can assume any
specific value or sub-range within the stated ranges in different
embodiments of the invention, to the tenth of the unit of the lower
limit of the range, unless the context clearly dictates
otherwise.
