BACKGROUND OF THE INVENTION
[0002] Epigenetic regulation of gene expression is an important
biological determinant of protein production and cellular
differentiation and plays a significant pathogenic role in a number
of human diseases.
[0003] Epigenetic regulation involves heritable modification of
genetic material without changing its nucleotide sequence.
Typically, epigenetic regulation is mediated by selective and
reversible modification (e.g., methylation) of DNA and proteins
(e.g., histones) that control the conformational transition between
transcriptionally active and inactive states of chromatin. These
covalent modifications can be controlled by enzymes such as
methyltransferases (e.g., PRMT5), many of which are associated with
specific genetic alterations that can cause human disease.
[0004] Disease-associated chromatin-modifying enzymes (e.g., PRMT5)
play a role in diseases such as proliferative disorders, metabolic
disorders, and blood disorders. Thus, there is a need for the
development of small molecules that are capable of inhibiting the
activity of PRMT5.
DETAILED DESCRIPTION OF CERTAIN EMBODIMENTS
[0005] Protein arginine methyltransferase 5 (PRMT5) catalyzes the
addition of two methyl groups to the two .omega.-guanidino nitrogen
atoms of arginine, resulting in .omega.-NG, N'G symmetric
dimethylation of arginine (sDMA) of the target protein. PRMT5
functions in the nucleus as well as in the cytoplasm, and its
substrates include histones, spliceosomal proteins, transcription
factors (See e.g., Sun et al., PNAS (2011), 108: 20538-20543).
PRMT5 generally functions as part of a molecule weight protein
complex. While the protein complexes of PRMT5 can have a variety of
components, they generally include the protein MEP50 (methylosome
protein 50). In addition, PRMT5 acts in conjunction with cofactor
SAM (S-adenosyl methionine).
[0006] PRMT5 is an attractive target for modulation given its role
in the regulation of diverse biological processes. It has now been
found that compounds described herein, and pharmaceutically
acceptable salts and compositions thereof, are effective as
inhibitors of PRMT5.
[0007] Such compounds have the general Formula (A):
##STR00002##
or a pharmaceutically acceptable salt thereof, wherein R.sup.1,
R.sup.5, R.sup.6, R.sup.7, R.sup.8, R.sup.x, R.sup.12, R.sup.13, n,
L, and Ar are as defined herein.
[0008] In some embodiments, the inhibitors of PRMT5 have the
general Formula (I):
##STR00003##
or a pharmaceutically acceptable salt thereof, wherein R.sup.1,
R.sup.5, R.sup.6, R.sup.7, R.sup.8, R.sup.x, n, L, and Ar are as
defined herein.
[0009] In some embodiments, pharmaceutical compositions are
provided which comprise a compound described herein (e.g, a
compound of Formula (A), e.g., Formula (I)), or a pharmaceutically
acceptable salt thereof, and optionally a pharmaceutically
acceptable excipient.
[0010] In certain embodiments, compounds described herein inhibit

one ring does not contain a heteroatom (e.g., indolyl, quinolinyl,
carbazolyl, and the like) the point of attachment can be on either
ring, e.g., either the ring bearing a heteroatom (e.g., 2-indolyl)
or the ring that does not contain a heteroatom (e.g.,
5-indolyl).
[0033] In some embodiments, a heteroaryl group is a 5-14 membered
aromatic ring system having ring carbon atoms and 1-4 ring
heteroatoms provided in the aromatic ring system, wherein each
heteroatom is independently selected from nitrogen, oxygen, and
sulfur ("5-14 membered heteroaryl"). In some embodiments, a
heteroaryl group is a 5-10 membered aromatic ring system having
ring carbon atoms and 1-4 ring heteroatoms provided in the aromatic
ring system, wherein each heteroatom is independently selected from
nitrogen, oxygen, and sulfur ("5-10 membered heteroaryl"). In some
embodiments, a heteroaryl group is a 5-8 membered aromatic ring
system having ring carbon atoms and 1-4 ring heteroatoms provided
in the aromatic ring system, wherein each heteroatom is
independently selected from nitrogen, oxygen, and sulfur ("5-8
membered heteroaryl"). In some embodiments, a heteroaryl group is a
5-6 membered aromatic ring system having ring carbon atoms and 1-4
ring heteroatoms provided in the aromatic ring system, wherein each
heteroatom is independently selected from nitrogen, oxygen, and
sulfur ("5-6 membered heteroaryl"). In some embodiments, the 5-6
membered heteroaryl has 1-3 ring heteroatoms independently selected
from nitrogen, oxygen, and sulfur. In some embodiments, the 5-6
membered heteroaryl has 1-2 ring heteroatoms independently selected
from nitrogen, oxygen, and sulfur. In some embodiments, the 5-6
membered heteroaryl has 1 ring heteroatom selected from nitrogen,
oxygen, and sulfur. In certain embodiments, each instance of a
heteroaryl group is independently optionally substituted, e.g.,
unsubstituted ("unsubstituted heteroaryl") or substituted
("substituted heteroaryl") with one or more substituents. In
certain embodiments, the heteroaryl group is unsubstituted 5-14
membered heteroaryl. In certain embodiments, the heteroaryl group
is substituted 5-14 membered heteroaryl.
[0034] Exemplary 5-membered heteroaryl groups containing one
heteroatom include, without limitation, pyrrolyl, furanyl and
thiophenyl. Exemplary 5-membered heteroaryl groups containing two
heteroatoms include, without limitation, imidazolyl, pyrazolyl,
oxazolyl, isoxazolyl, thiazolyl, and isothiazolyl. Exemplary
5-membered heteroaryl groups containing three heteroatoms include,
without limitation, triazolyl, oxadiazolyl, and thiadiazolyl.
Exemplary 5-membered heteroaryl groups containing four heteroatoms
include, without limitation, tetrazolyl. Exemplary 6-membered
heteroaryl groups containing one heteroatom include, without
limitation, pyridinyl. Exemplary 6-membered heteroaryl groups
containing two heteroatoms include, without limitation,

limitation, indolyl, isoindolyl, indazolyl, benzotriazolyl,
benzothiophenyl, isobenzothiophenyl, benzofuranyl, benzoisofuranyl,
benzimidazolyl, benzoxazolyl, benzisoxazolyl, benzoxadiazolyl,
benzthiazolyl, benzisothiazolyl, benzthiadiazolyl, indolizinyl, and
purinyl. Exemplary 6,6-bicyclic heteroaryl groups include, without
limitation, naphthyridinyl, pteridinyl, quinolinyl, isoquinolinyl,
cinnolinyl, quinoxalinyl, phthalazinyl, and quinazolinyl.
[0035] "Fused" or "ortho-fused" are used interchangeably herein,
and refer to two rings that have two atoms and one bond in common,
e.g.,
##STR00005##
[0036] "Bridged" refers to a ring system containing (1) a
bridgehead atom or group of atoms which connect two or more
non-adjacent positions of the same ring; or (2) a bridgehead atom
or group of atoms which connect two or more positions of different
rings of a ring system and does not thereby form an ortho-fused
ring, e.g,
##STR00006##
[0037] "Spiro" or "Spiro-fused" refers to a group of atoms which
connect to the same atom of a carbocyclic or heterocyclic ring
system (geminal attachment), thereby forming a ring, e.g,
##STR00007##
Spiro-fusion at a bridgehead atom is also contemplated.
[0038] "Partially unsaturated" refers to a group that includes at
least one double or triple bond. The term "partially unsaturated"
is intended to encompass rings having multiple sites of
unsaturation, but is not intended to include aromatic groups (e.g.,
aryl or heteroaryl groups) as herein defined. Likewise, "saturated"
refers to a group that does not contain a double or triple bond,
i.e., contains all single bonds.
[0039] In some embodiments, aliphatic, alkyl, alkenyl, alkynyl,
carbocyclyl, heterocyclyl, aryl, and heteroaryl groups, as defined
herein, are optionally substituted (e.g., "substituted" or
"unsubstituted" aliphatic, "substituted" or "unsubstituted" alkyl,
"substituted" or "unsubstituted" alkenyl, "substituted" or
"unsubstituted" alkynyl, "substituted" or "unsubstituted"
carbocyclyl, "substituted" or "unsubstituted" heterocyclyl,
"substituted" or "unsubstituted" aryl or "substituted" or
"unsubstituted" heteroaryl group). In general, the term
"substituted", whether preceded by the term "optionally" or not,
means that at least one hydrogen present on a group (e.g., a carbon
or nitrogen atom) 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, including any of the substituents described herein that
results in the formation of a stable compound. The present
disclosure contemplates any and all such combinations in order to
arrive at a stable compound. For purposes of this disclosure,
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.

Wuts, 3.sup.rd edition, John Wiley & Sons, 1999, incorporated
herein by reference.
[0059] As used herein, a "leaving group", or "LG", is a term
understood in the art to refere to a molecular fragment that
departs with a pair of electrons upon heterolytic bond cleavage,
wherein the molecular fragment is an anion or neutral molecule.
See, for example, Smith, March Advanced Organic Chemistry 6th ed.
(501-502). Examples of suitable leaving groups include, but are not
limited to, halides (such as chloride, bromide, or iodide),
alkoxycarbonyloxy, aryloxycarbonyloxy, alkanesulfonyloxy,
arenesulfonyloxy, alkyl-carbonyloxy (e.g., acetoxy),
arylcarbonyloxy, aryloxy, methoxy, N,O-dimethylhydroxylamino,
pixyl, haloformates, --NO.sub.2, trialkylammonium, and aryliodonium
salts. In some embodiments, the leaving group is a sulfonic acid
ester. In some embodiments, the sulfonic acid ester comprises the
formula --OSO.sub.2RL.sup.G1 wherein R.sup.LG1 is selected from the
group consisting alkyl optionally, alkenyl optionally substituted,
heteroalkyl optionally substituted, aryl optionally substituted,
heteroaryl optionally substituted, arylalkyl optionally
substituted, and heterarylalkyl optionally substituted. In some
embodiments, R.sup.LG1 is substituted or unsubstituted
C.sub.1-C.sub.6 alkyl. In some embodiments, R.sup.LG1 is methyl. In
some embodiments, R.sup.LG1 is --CF.sub.3. In some embodiments,
R.sup.LG1 is substituted or unsubstituted aryl. In some

##STR00008##
[0060] In some cases, the leaving group is toluenesulfonate
(tosylate, Ts), methanesulfonate (mesylate, Ms),
p-bromobenzenesulfonyl (brosylate, Bs), or
trifluoromethanesulfonate (triflate, Tf). In some cases, the
leaving group is a brosylate (p-bromobenzenesulfonyl). In some
cases, the leaving group is a nosylate (2-nitrobenzenesulfonyl). In
some embodiments, the leaving group is a sulfonate-containing
group. In some embodiments, the leaving group is a tosylate group.
The leaving group may also be a phosphineoxide (e.g., formed during
a Mitsunobu reaction) or an internal leaving group such as an
epoxide or cyclic sulfate.
[0061] These and other exemplary substituents are described in more
detail in the Detailed Description, Examples, and claims. The
present disclosure is not intended to be limited in any manner by
the above exemplary listing of substituents.
[0062] "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 other 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.
Pharmaceutically acceptable salts of the compounds describe herein
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 used 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+(C.sub.1-4alkyl).sub.4 salts.
Representative alkali or alkaline earth metal salts include sodium,
lithium, potassium, calcium, magnesium, and the like. Further
pharmaceutically acceptable salts include, when appropriate,
quaternary salts.
[0063] A "subject" to which administration is contemplated
includes, but is not limited to, humans (e.g., a male or female of
any age group, e.g., a pediatric subject (e.g, infant, child,
adolescent) or adult subject (e.g., young adult, middle-aged adult
or senior adult)) and/or other non-human animals, for example,
non-human mammals (e.g., primates (e.g., cynomolgus monkeys, rhesus
monkeys); commercially relevant mammals such as cattle, pigs,
horses, sheep, goats, cats, and/or dogs), birds (e.g., commercially
relevant birds such as chickens, ducks, geese, and/or turkeys),
rodents (e.g., rats and/or mice), reptiles, amphibians, and fish.
In certain embodiments, the non-human animal is a mammal. The
non-human animal may be a male or female at any stage of
development. A non-human animal may be a transgenic animal.
[0064] "Condition," "disease," and "disorder" are used
interchangeably herein.
[0065] "Treat," "treating" and "treatment" encompasses an action
that occurs while a subject is suffering from a condition which
reduces the severity of the condition or retards or slows the
progression of the condition ("therapeutic treatment"). "Treat,"
"treating" and "treatment" also encompasses an action that occurs
before a subject begins to suffer from the condition and which
inhibits or reduces the severity of the condition ("prophylactic
treatment").
[0066] An "effective amount" of a compound refers to an amount
sufficient to elicit the desired biological response, e.g., treat
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.
[0067] A "therapeutically effective amount" of a compound 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 or causes of
the condition, or enhances the therapeutic efficacy of another
therapeutic agent.
[0068] A "prophylactically effective amount" of a compound 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.
[0069] As used herein, the term "methyltransferase" represents
transferase class enzymes that are able to transfer a methyl group
from a donor molecule to an acceptor molecule, e.g., an amino acid
residue of a protein or a nucleic base of a DNA molecule.
Methytransferases typically use a reactive methyl group bound to
sulfur in S-adenosyl methionine (SAM) as the methyl donor. In some
embodiments, a methyltransferase described herein is a protein
methyltransferase. In some embodiments, a methyltransferase
described herein is a histone methyltransferase. Histone
methyltransferases (HMT) are histone-modifying enzymes, (including
histone-lysine N-methyltransferase and histone-arginine
N-methyltransferase), that catalyze the transfer of one or more
methyl groups to lysine and arginine residues of histone proteins.
In certain embodiments, a methyltransferase described herein is a
histone-arginine N-methyltransferase.
[0070] As generally described above, provided herein are compounds
useful as PRMT5 inhibitors. In some embodiments, the present
disclosure provides a compound of Formula (A):

nitrogen containing ring, wherein the point of attachment to the
parent moiety is on the nitrogen, and wherein the fused bicyclic

General considerations in formulation and/or manufacture of
pharmaceutical compositions agents can be found, for example, in
Remington's Pharmaceutical Sciences, Sixteenth Edition, E. W.
Martin (Mack Publishing Co., Easton, Pa., 1980), and Remington: The
Science and Practice of Pharmacy, 21st Edition (Lippincott Williams
& Wilkins, 2005).
[0294] Pharmaceutical compositions described herein can be prepared
by any method known in the art of pharmacology. In general, such
preparatory methods include the steps of bringing a compound
described herein (the "active ingredient") into association with a
carrier and/or one or more other accessory ingredients, and then,
if necessary and/or desirable, shaping and/or packaging the product
into a desired single- or multi-dose unit.
[0295] Pharmaceutical compositions can be prepared, packaged,
and/or sold in bulk, as a single unit dose, and/or as a plurality
of single unit doses. As used herein, a "unit dose" is discrete
amount of the pharmaceutical composition comprising a predetermined
amount of the active ingredient. The amount of the active
ingredient is generally equal to the dosage of the active
ingredient which would be administered to a subject and/or a
convenient fraction of such a dosage such as, for example, one-half
or one-third of such a dosage.
[0296] Relative amounts of the active ingredient, the
pharmaceutically acceptable excipient, and/or any additional
ingredients in a pharmaceutical composition of the present
disclosure will vary, depending upon the identity, size, and/or
condition of the subject treated and further depending upon the
route by which the composition is to be administered. By way of
example, the composition may comprise between 0.1% and 100% (w/w)
active ingredient.

[0311] 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
alcohol, benzyl benzoate, propylene glycol, 1,3-butylene glycol,
dimethylformamide, oils (e.g., cottonseed, groundnut, corn, germ,
olive, castor, and sesame oils), glycerol, tetrahydrofurfuryl
alcohol, polyethylene glycols and fatty acid esters of sorbitan,
and mixtures thereof. Besides inert diluents, the oral compositions
can include adjuvants such as wetting agents, emulsifying and
suspending agents, sweetening, flavoring, and perfuming agents. In
certain embodiments for parenteral administration, the compounds
described herein are mixed with solubilizing agents such as
Cremophor.TM., alcohols, oils, modified oils, glycols,
polysorbates, cyclodextrins, polymers, and mixtures thereof.
[0312] 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 diglycerides. In addition, fatty acids such as
oleic acid are used in the preparation of injectables.
[0313] 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.
[0314] 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 is accomplished
by dissolving or suspending the drug in an oil vehicle.
[0315] Compositions for rectal or vaginal administration are
typically suppositories which can be prepared by mixing the
compounds 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.
[0316] 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 comprise buffering agents.
[0317] 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 pharmaceutical formulating art. 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 embedding 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.
[0318] The active ingredient can be in 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
embedding compositions which can be used include polymeric
substances and waxes.
[0319] Dosage forms for topical and/or transdermal administration
of a provided compound 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 and/or any
desired preservatives and/or buffers as can be required.
Additionally, the present disclosure encompasses 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.
[0320] Suitable devices for use in delivering intradermal
pharmaceutical compositions described herein include short needle
devices such as those described in U.S. Pat. Nos. 4,886,499;
5,190,521; 5,328,483; 5,527,288; 4,270,537; 5,015,235; 5,141,496;
and 5,417,662. Intradermal compositions can be administered by
devices which limit the effective penetration length of a needle
into the skin, such as those described in PCT publication WO
99/34850 and functional equivalents thereof. Jet injection devices
which deliver liquid vaccines 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. Jet injection
devices are described, for example, in U.S. Pat. Nos. 5,480,381;
5,599,302; 5,334,144; 5,993,412; 5,649,912; 5,569,189; 5,704,911;
5,383,851; 5,893,397; 5,466,220; 5,339,163; 5,312,335; 5,503,627;
5,064,413; 5,520,639; 4,596,556; 4,790,824; 4,941,880; 4,940,460;
and PCT publications WO 97/37705 and WO 97/13537. Ballistic
powder/particle delivery devices which use compressed gas to
accelerate vaccine in powder form through the outer layers of the
skin to the dermis are suitable. Alternatively or additionally,
conventional syringes can be used in the classical mantoux method
of intradermal administration.
[0321] 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.
[0322] A provided pharmaceutical composition 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.
[0323] 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).
[0324] Pharmaceutical compositions 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.
[0325] Formulations described herein as being useful for pulmonary
delivery are useful for intranasal delivery of a pharmaceutical
composition. 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.
[0326] Formulations for nasal administration may, for example,
comprise from about as little as 0.1% (w/w) and as much as 100%
(w/w) of the active ingredient, and may comprise one or more of the
additional ingredients described herein. A provided pharmaceutical
composition can be prepared, packaged, and/or sold in a formulation
for buccal administration. Such formulations may, for example, be
in the form of tablets and/or lozenges made using conventional
methods, and may contain, for example, 0.1 to 20% (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.
[0327] A provided pharmaceutical composition 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, a 0.1/1.0% (w/w) solution
and/or suspension of the active ingredient in an aqueous or oily
liquid carrier. 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 contemplated as being within the scope
of this disclosure.
[0328] Although the descriptions of pharmaceutical compositions
provided herein are principally directed to pharmaceutical
compositions which are suitable for administration to humans, it
will be understood by the skilled artisan that such compositions
are generally suitable for administration to animals of all sorts.
Modification of pharmaceutical compositions suitable for
administration to humans in order to render the compositions
suitable for administration to various animals is well understood,
and the ordinarily skilled veterinary pharmacologist can design
and/or perform such modification with ordinary experimentation.
[0329] Compounds provided herein are typically formulated in dosage
unit form for ease of administration and uniformity of dosage. It
will be understood, however, that the total daily usage of provided
compositions will be decided by the attending physician within the
scope of sound medical judgment. The specific therapeutically
effective dose level for any particular subject or organism will
depend upon a variety of factors including the disease, disorder,
or condition being treated and the severity of the disorder; the
activity of the specific active ingredient employed; the specific
composition employed; the age, body weight, general health, sex and
diet of the subject; the time of administration, route of
administration, and rate of excretion of the specific active
ingredient employed; the duration of the treatment; drugs used in
combination or coincidental with the specific active ingredient
employed; and like factors well known in the medical arts.
[0330] The compounds and compositions provided herein can be
administered by any route, including enteral (e.g., oral),
parenteral, intravenous, intramuscular, intra-arterial,
intramedullary, intrathecal, subcutaneous, intraventricular,
transdermal, interdermal, rectal, intravaginal, intraperitoneal,
topical (as by powders, ointments, creams, and/or drops), mucosal,
nasal, bucal, sublingual; by intratracheal instillation, bronchial
instillation, and/or inhalation; and/or as an oral spray, nasal
spray, and/or aerosol. Specifically contemplated routes are oral
administration, intravenous administration (e.g., systemic
intravenous injection), regional administration via blood and/or
lymph supply, and/or direct administration to an affected site. In
general the most appropriate route of administration will depend
upon a variety of factors including the nature of the agent (e.g.,
its stability in the environment of the gastrointestinal tract),
and/or the condition of the subject (e.g., whether the subject is
able to tolerate oral administration).
[0331] The exact amount of a compound required to achieve an
effective amount will vary from subject to subject, depending, for
example, on species, age, and general condition of a subject,
severity of the side effects or disorder, identity of the
particular compound(s), mode of administration, and the like. The
desired dosage can be delivered three times a day, two times a day,
once a day, every other day, every third day, every week, every two
weeks, every three weeks, or every four weeks. In certain
embodiments, the desired dosage can be delivered using multiple
administrations (e.g., two, three, four, five, six, seven, eight,
nine, ten, eleven, twelve, thirteen, fourteen, or more
administrations).
[0332] In certain embodiments, an effective amount of a compound
for administration one or more times a day to a 70 kg adult human
may comprise about 0.0001 mg to about 3000 mg, about 0.0001 mg to
about 2000 mg, about 0.0001 mg to about 1000 mg, about 0.001 mg to

[0340] Compounds and compositions described herein are generally
useful for the inhibition of PRMT5. In some embodiments, methods of
treating PRMT5-mediated disorder in a subject are provided which
comprise administering an effective amount of a compound described
herein (e.g., a compound of Formula (A), e.g., Formula (I)), or a
pharmaceutically acceptable salt thereof), to a subject in need of
treatment. In certain embodiments, the effective amount is a
therapeutically effective amount. In certain embodiments, the
effective amount is a prophylactically effective amount. In certain
embodiments, the subject is suffering from a PRMT5-mediated
disorder. In certain embodiments, the subject is susceptible to a
PRMT5-mediated disorder.
[0341] As used herein, the term "PRMT5-mediated disorder" means any
disease, disorder, or other pathological condition in which PRMT5
is known to play a role. Accordingly, in some embodiments, the
present disclosure relates to treating or lessening the severity of
one or more diseases in which PRMT5 is known to play a role.
[0342] In some embodiments, the present disclosure provides a
method of inhibiting PRMT5 comprising contacting PRMT5 with an
effective amount of a compound described herein (e.g., a compound
of Formula (A), e.g., Formula (I)), or a pharmaceutically
acceptable salt thereof. The PRMT5 may be purified or crude, and
may be present in a cell, tissue, or subject. Thus, such methods
encompass both inhibition of in vitro and in vivo PRMT5 activity.
In certain embodiments, the method is an in vitro method, e.g.,
such as an assay method. It will be understood by one of ordinary
skill in the art that inhibition of PRMT5 does not necessarily
require that all of the PRMT5 be occupied by an inhibitor at once.
Exemplary levels of inhibition of PRMT5 include at least 10%
inhibition, about 10% to about 25% inhibition, about 25% to about
50% inhibition, about 50% to about 75% inhibition, at least 50%
inhibition, at least 75% inhibition, about 80% inhibition, about
90% inhibition, and greater than 90% inhibition.
[0343] In some embodiments, provided is a method of inhibiting
PRMT5 activity in a subject in need thereof comprising
administering to the subject an effective amount of a compound
described herein (e.g., a compound of Formula (A), e.g., Formula
(I)), or a pharmaceutically acceptable salt thereof, or a
pharmaceutical composition thereof.
[0344] In certain embodiments, provided is a method of altering
gene expression in a cell which comprises contacting a cell with an
effective amount of a compound of Formula (A), e.g., Formula (I),
or a pharmaceutically acceptable salt thereof. In certain
embodiments, the cell in culture in vitro. In certain embodiments,
the cell is in an animal, e.g., a human. In certain embodiments,
the cell is in a subject in need of treatment.
[0345] In certain embodiments, provided is a method of altering
transcription in a cell which comprises contacting a cell with an
effective amount of a compound of Formula (A), e.g., Formula (I),
or a pharmaceutically acceptable salt thereof. In certain
embodiments, the cell in culture in vitro. In certain embodiments,
the cell is in an animal, e.g., a human. In certain embodiments,
the cell is in a subject in need of treatment.
[0346] In certain embodiments, a method is provided of selecting a
therapy for a subject having a disease associated with
PRMT5-mediated disorder or mutation comprising the steps of
determining the presence of PRMT5-mediated disorder or gene
mutation in the PRMT5 gene or and selecting, based on the presence
of PRMT5-mediated disorder a gene mutation in the PRMT5 gene a
therapy that includes the administration of a provided compound. In
certain embodiments, the disease is cancer.
[0347] In certain embodiments, a method of treatment is provided
for a subject in need thereof comprising the steps of determining
the presence of PRMT5-mediated disorder or a gene mutation in the
PRMT5 gene and treating the subject in need thereof, based on the
presence of a PRMT5-mediated disorder or gene mutation in the PRMT5
gene with a therapy that includes the administration of a provided
compound. In certain embodiments, the subject is a cancer
patient.
[0348] In some embodiments, a provided compound is useful in
treating a proliferative disorder, such as cancer, a benign
neoplasm, an autoimmune disease, or an inflammatory disease. For
example, while not being bound to any particular mechanism, PRMT5
has been shown to be involved in cyclin D1 dysregulated cancers.
Increased PRMT5 activity mediates key events associated with cyclin
D1-dependent neoplastic growth including CUL4 repression, CDT1
overexpression, and DNA re-replication. Further, human cancers
harboring mutations in Fbx4, the cyclin D1 E3 ligase, exhibit
nuclear cyclin D1 accumulation and increased PRMT5 activity. See,
e.g., Aggarwal et al., Cancer Cell. (2010) 18(4):329-40.
Additionally, PRMT5 has also been implicated in accelerating cell
cycle progression through G1 phase and modulating regulators of G1;
for example, PRMT5 may upregulate cyclin-dependent kinase (CDK) 4,
CDK6, and cyclins D1, D2 and E1. Moreover, PRMT5 may activate
phosphoinositide 3-kinase (PI3K)/AKT signaling. See, e.g., Wei et
al., Cancer Sci. (2012) 103(9): 1640-50. PRMT5 has been reported to
play a role in apoptosis through methylation of E2F-1. See, e.g.,
Cho et al., EMBO J. (2012) 31:1785-1797; Zheng et al., Mol. Cell.
(2013) 52:37-51. PRMT5 has been reported to be an essential
regulator of splicing and affect the alternative splicing of
`sensor` mRNAs that can then lead to defects in downstream events
such as apoptosis. See, e.g., Bezzi et al., Genes Dev. (2013)
27:1903-1916. PRMT5 has been reported to play a role in the RAS-ERK
pathway. See, e.g., Andrew-Perez et al., Sci Signal. (2011) Sep.
13; 4(190)ra58 doi: 10.1126/scisignal.2001936. PRMT5 has been
reported to affect C/EBPb target genes through interaction with the
Mediator complex and hence affect cellular differentiation and
inflammatory response. See, e.g., Tsutsui et al., J. Biol. Chem.
(2013) 288:20955-20965. PRMT5 has been shown to methylate HOXA9
essential for ELAM expression during the EC inflammatory response.
See, e.g., Bandyopadhyay et al., Mol. Cell. Biol. (2012)
32:1202-1203. Thus in some embodiments, the inhibition of PRMT5 by
a provided compound is useful in treating the following

[0351] In some embodiments, a provided compound is useful in
treating a metabolic disorder, such as diabetes or obesity. For
example, while not being bound to any particular mechanism, a role
for PRMT5 has been recognized in adipogenesis. Inhibition of PRMT5
expression in multiple cell culture models for adipogenesis
prevented the activation of adipogenic genes, while overexpression
of PRMT5 enhanced adipogenic gene expression and differentiation.
See, e.g., LeBlanc et al., Mol Endocrinol. (2012) 26:583-597.
Additionally, it has been shown that adipogenesis plays a pivotal
role in the etiology and progression of diabetes and obesity. See,

[0353] In some embodiments, a provided compound is useful in
treating a blood disorder, e.g., a hemoglobinopathy, such as sickle

in adulthood are associated with symptomatic amelioration in sickle
cell disease and .beta.-thalassemia. See, e.g., Xu et al.,
Haematologica. (2012) 97:1632-1640; Rank et al. Blood. (2010)

or under Staudinger condition in the presence of PPh.sub.3 (azide)
or hydrazine (Phthalimide)). The target amine analog can be
obtained via reductive amination using S2 conditions similar to
those described in Scheme 4. Additional modification of the Ar

[0711] General Procedure for PRMT5/MEP50 Enzyme Assays on Peptide
Substrates. The assays were all performed in a buffer consisting of
20 mM Bicine (pH=7.6), 1 mM TCEP, 0.005% BSG, and 0.002% Tween20,
prepared on the day of use. Compounds in 100% DMSO (1 ul) were
spotted into a polypropylene 384-well V-bottom plates (Greiner)
using a Platemate Plus outfitted with a 384-channel head (Thermo
Scientific). DMSO (1 ul) was added to Columns 11, 12, 23, 24, rows
A-H for the maximum signal control and 1 ul of SAH, a known product
and inhibitor of PRMT5/MEP50, was added to columns 11, 12, 23, 24,
rows I-P for the minimum signal control. A cocktail (40 ul)
containing the PRMT5/MEP50 enzyme and the peptide was added by
Multidrop Combi (Thermo-Fisher). The compounds were allowed to
incubate with PRMT5/MEP50 for 30 min at 25 degrees Celsius, then a
cocktail (10 ul) containing .sup.3H-SAM was added to initiate the
reaction (final volume=51 ul). The final concentrations of the
components were as follows: PRMT5/MEP50 was 4 nM, .sup.3H-SAM was
75 nM, peptide was 40 nM, SAH in the minimum signal control wells
was 100 uM, and the DMSO concentration was 1%. The assays were
stopped by the addition of non-radioactive SAM (10 ul) to a final
concentration of 600 uM, which dilutes the .sup.3H-SAM to a level
where its incorporation into the peptide substrate is no longer
detectable. 50 ul of the reaction in the 384-well polypropylene
plate was then transferred to a 384-well Flashplate and the
biotinylated peptides were allowed to bind to the streptavidin
surface for at least 1 hour before being washed three times with
0.1% Tween20 in a Biotek ELx405 plate washer. The plates were then
read in a PerkinElmer TopCount plate reader to measure the quantity
of .sup.3H-labeled peptide bound to the Flashplate surface,
measured as disintegrations per minute (dpm) or alternatively,
referred to as counts per minute (cpm).

control type was calculated and used to determine the percent
inhibition for each test well in the plate. Reference compound was
serially diluted three-fold in DMSO for a total of nine test
concentrations, beginning at 3 .mu.M. Percent inhibition was
determined and IC.sub.50 curves were generated using triplicate
wells per concentration of compound.

Z-138 Proliferation Assay
[0717] Z-138 suspension cells were purchased from ATCC (American
Type Culture Collection, Manassas, Va.). RPMI/Glutamax medium,
penicillin-streptomycin, heat inactivated fetal bovine serum were
purchased from Life Technologies, Grand Island, N.Y., USA. V-bottom
polypropylene 384-well plates were purchased from Greiner Bio-One,
Monroe, N.C., USA. Cell culture 384-well white opaque plates were
purchased from Perkin Elmer, Waltham, Mass., USA. Cell-Titer
Glo.RTM. was purchased from Promega Corporation, Madison, Wis.,
USA. SpectraMax M5 plate reader was purchased from Molecular
Devices LLC, Sunnyvale, Calif., USA.
[0718] Z-138 suspension cells were maintained in growth medium
(RPMI 1640 supplemented with 10% v/v heat inactivated fetal bovine
serum and cultured at 37.degree. C. under 5% CO.sub.2. Under assay
conditions, cells were incubated in assay medium (RPMI 1640
supplemented with 10% v/v heat inactivated fetal bovine serum and
100 units/mL penicillin-streptomycin) at 37.degree. C. under 5%
CO.sub.2.
[0719] For the assessment of the effect of compounds on the
proliferation of the Z-138 cell line, exponentially growing cells
were plated in 384-well white opaque plates at a density of 10,000
cells/ml in a final volume of 50 .mu.l of assay medium. A compound
source plate was prepared by performing triplicate nine-point
3-fold serial dilutions in DMSO, beginning at 10 mM (final top
concentration of compound in the assay was 20 .mu.M and the DMSO
was 0.2%). A 100 nL aliquot from the compound stock plate was added
to its respective well in the cell plate. The 100% inhibition
control consisted of cells treated with 200 nM final concentration
of staurosporine and the 0% inhibition control consisted of DMSO
treated cells. After addition of compounds, assay plates were
incubated for 5 days at 37.degree. C., 5% CO.sub.2, relative
humidity >90%.
[0720] Cell viability was measured by quantitation of ATP present
in the cell cultures, adding 35 .mu.l of Cell Titer Glo.RTM.
reagent to the cell plates. Luminescence was read in the SpectraMax
M5 microplate reader. The concentration of compound inhibiting cell
viability by 50% was determined using a 4-parametric fit of the
normalized dose response curves.
