2. FIELD
[0002] The present invention relates to 2,4 pyrimidinediamine
compounds that exhibit antiproliferative activity, prodrugs of the
compounds, intermediates and methods of synthesis for making the
compounds and/or prodrugs, pharmaceutical compositions comprising
the compounds and the use of the compounds in a variety of
contexts, including for the treatment of proliferative disorders,
such as, for example, tumors and cancers.
3. BACKGROUND
[0003] Cancer is a group of varied diseases characterized by
uncontrolled growth and spread of abornmal cells. Generally, all
types of cancers involve some abnormality in the control of cell
growth and division. The pathways regulating cell division and/or
cellular communication become altered in cancer cells such that the
effects of these regulatory mechanisms in controlling and limiting
cell growth fails or is bypassed. Through successive rounds of
mutation and natural selection, a group of abnormal cells,
generally originating from a single mutant cell, accumulates
additional mutations that provide selective growth advantage over
other cells, and thus evolves into a cell type that predominates in
the cell mass. This process of mutation and natural selection is
enhanced by genetic instability displayed by many types of cancer
cells, an instability which is gained either from somatic mutations
or by inheritance from the germ line. The enhanced mutability of
cancerous cells increases the probability of their progression
towards formation of malignant cells. As the cancer cells further
evolve, some become locally invasive and then metastasize to
colonize tissues other than the cancer cell's tissue of origin.
This property along with the heterogeneity of the tumor cell
population makes cancer a particularly difficult disease to treat
and eradicate.
[0004] Traditional cancer treatments take advantage of the higher
proliferative capacity of cancer cells and their increased
sensitivity to DNA damage. Ionizing radiation, including
.gamma.-rays and x-rays, and cytotoxic agents, such as bleomycin,
cis-platin, vinblastine, cyclophosphamide, 5'-fluorouracil, and
methotrexate rely upon a generalized damage to DNA and
destabilization of chromosomal structure which eventually lead to
destruction of cancer cells. These treatments are particularly
effective for those types of cancers that have defects in cell
cycle checkpoint, which limits the ability of these cells to repair
damaged DNA before undergoing cell division. The non-selective
nature of these treatments, however, often results in severe and
debilitating side effects. The systemic use of these drugs may
result in damage to normally healthy organs and tissues, and
compromise the long term health of the patient.
[0005] Although more selective chemotherapeutic treatments have
been developed based on knowledge of how cancer cells develop, for
example, the anti-estrogen compound tamoxifen, the effectiveness of
all chemotherapeutic treatments are subject to development of
resistance to the drugs. In particular, the increased expression of
cell membrane bound transporters, such as MdrI, produces a
multidrug resistance phenotype characterized by increased efflux of
drugs from the cell. These types of adaptation by cancer cells
severely limit the effectiveness of certain classes of
chemotherapeutic agents. Consequently, identification of other
chemotherapeutic agents is critical for establishing therapies
effective for attacking the heterogeneous nature of proliferative
disease and for overcoming any resistance that may develop over the
course of therapy with other compounds. Moreover, use of
combinations of chemotherapeutic agents with differing properties
and cellular targets increases the effectiveness of chemotherapy
and limits the generation of drug resistance.

[0037] In another aspect, the present invention provides prodrugs
of the 2,4-pyrimidinediamine compounds. Such prodrugs may be active
in their prodrug form, or may be inactive until converted under
physiological or other conditions of use to an active drug form. In
the prodrugs, one or more functional groups of the
2,4-pyrimidinediamine compounds are included in promoieties that
cleave from the molecule under the conditions of use, typically by
way of hydrolysis, enzymatic cleavage or some other cleavage
mechanism, to yield the functional groups. For example, primary or
secondary amino groups may be included in an amide promoiety that
cleaves under conditions of use to generate the primary or
secondary amino group. Thus, the prodrugs include special types of
protecting groups, termed "progroups," masking one or more
functional groups of the 2,4-pyrimidinediamine compounds that
cleave under the conditions of use to yield an active
2,4-pyrimidinediamine drug compound. Functional groups within the
2,4-pyrimidinediamine compounds that may be masked with progroups
for inclusion in a promoiety include, but are not limited to,
amines (primary and secondary), hydroxyls, sulfanyls (thiols),
carboxyls, carbonyls, phenols, catechols, diols, alkynes,
phosphates, etc. Myriad progroups suitable for masking such
functional groups to yield promoieties that are cleavable under the
desired conditions of use are known in the art. All of these
progroups, alone or in combinations, may be included in the
prodrugs. Specific examples of promoieties that yield primary or
secondary amine groups that can be included in the prodrugs
include, but are not limited to amides, carbamates, imines, ureas,
phosphenyls, phosphoryls and sulfenyls. Specific examples of
promoieties that yield sulfanyl groups that can be included in the
prodrugs include, but are not limited to, thioethers, for example
S-methyl derivatives (monothio, dithio, oxythio, aminothio
acetals), silyl thioethers, thioesters, thiocarbonates,
thiocarbamates, asymmetrical disulfides, etc. Specific examples of
promoieties that cleave to yield hydroxyl groups that can be
included in the prodrugs include, but are not limited to,
sulfonates, esters and carbonates. Specific examples of promoieties
that yield carboxyl groups that can be included in the prodrugs
include, but are not limited to, esters (including silyl esters,
oxamic acid esters and thioesters), amides and hydrazides.
[0038] In another aspect, the present invention provides
compositions comprising one or more 2,4-pyrimidinediamine compounds
and/or prodrugs and an appropriate carrier, excipient and/or
diluent. The exact nature of the carrier, excipient and/or diluent
will depend on the desired use for the composition, and may range
from being suitable or acceptable for veterinary uses to being
suitable or acceptable for human use.
[0039] The 2,4-pyrimidinediamine compounds are potent inhibitors of
proliferation abnormal cells, such as tumor cell proliferation, in
in vitro assays. Thus, in still another aspect, the present
invention provides methods of inhibiting proliferation of abnormal
cells, in particular tumor cells. The method generally involves
contacting an abnormal cell such as a tumor cells with an amount of
a 2,4-pyrimidinediamine compound or prodrug, or an acceptable salt,
hydrate, solvate, N-oxide and/or composition thereof, effective to
inhibit its proliferation. The method may be practiced in in vitro
contexts or in in vivo contexts as a therapeutic approach towards
the treatment or prevention of proliferative disorders, such as
tumorigenic cancers.
[0040] In still another aspect, the present invention provides
methods of treating proliferative disorders. The methods may be
practiced in animals in veterinary contexts or in humans. The
methods generally involve administering to an animal or human
subject an amount of a 2,4-pyrimidinediamine compound or prodrug,
or an acceptable salt, hydrate, solvate, N-oxide and/or composition
thereof, effective to treat the disorder. Proliferative disorders
that can be treated according to the methods include, but are not
limited to, tumorigenic cancers.
[0041] Other aspects of the present invention include, but are not
limited to, intermediates and methods useful for synthesizing the
compound and prodrugs, as will be described in more detail herein
below.

is replaced with a heteroatom, for example, a heteroatom selected
from O, S and N. In heteroalkyl groups including more than one
heteroatom, the heteroatoms may be the same or they may be

[0060] "Aryl" by itself or as part of another substituent refers to
a monovalent aromatic hydrocarbon group having the stated number of
carbon atoms (i.e., C5-C15 means from 5 to 15 carbon atoms) derived
by the removal of one hydrogen atom from a single carbon atom of a
parent aromatic ring system. Typical aryl groups include, but are
not limited to, groups derived from aceanthrylene, acenaphthylene,

with (C5-C10) being even more preferred. Particularly preferred
aryls are phenyl and naphthyl.
[0061] "Halogen" or "Halo" by themselves or as part of another
substituent, unless otherwise stated, refer to fluoro, chloro,
bromo and iodo.
[0062] "Haloalkyl" by itself or as part of another substituent
refers to an alkyl group in which one or more of the hydrogen atoms
is replaced with a halogen. Thus, the term "haloalkyl" is meant to
include monohaloalkyls, dihaloalkyls, trihaloalkyls, etc. up to
perhaloalkyls. For example, the expression "(C1-C2) haloalkyl"
includes fluoromethyl, difluoromethyl, trifluoromethyl,
1-fluoroethyl, 1,1-difluoroethyl, 1,2-difluoroethyl,
1,1,1-trifluoroethyl, perfluoroethyl, etc.
[0063] The above-defined groups may include prefixes and/or
suffixes that are commonly used in the art to create additional
well-recognized substituent groups. As non-limiting examples,
"alkyloxy" or "alkoxy" refers to a group of the formula --OR,
"alkylamine" refers to a group of the formula --NHR and
"dialkylamine" refers to a group of the formula --NRR, where each R
is independently an alkyl. As another non-limiting example,
"haloalkoxy" or "haloalkyloxy" refers to a group of the formula
--OR', where R' is a haloalkyl.
[0064] "Prodrug" refers to a derivative of an active
2,4-pyrimidinediamine compound (drug) that may require a
transformation under the conditions of use, such as within the
body, to release the active 2,4-pyrimidinediamine drug. Prodrugs
are frequently, but not necessarily, pharmacologically inactive
until converted into the active drug. Prodrugs are typically
obtained by masking a functional group in the 2,4-pyrimidinediamine
drug believed to be in part required for activity with a progroup
(defined below) to form a promoiety which undergoes a
transformation, such as cleavage, under the specified conditions of
use to release the functional group, and hence the active
2,4-pyrimidinediamine drug. The cleavage of the promoiety may
proceed spontaneously, such as by way of a hydrolysis reaction, or
it may be catalyzed or induced by another agent, such as by an
enzyme, by light, by acid or base, or by a change of or exposure to
a physical or environmental parameter, such as a change of
temperature. The agent may be endogenous to the conditions of use,
such as an enzyme present in the cells to which the prodrug is
administered or the acidic conditions of the stomach, or it may be
supplied exogenously.
[0065] A wide variety of progroups, as well as the resultant
promoieties, suitable for masking functional groups in the active
2,4-pyrimidinediamines compounds to yield prodrugs are well-known
in the art. For example, a hydroxyl functional group may be masked
as a sulfonate, ester or carbonate promoiety, which may be
hydrolyzed in vivo to provide the hydroxyl group. An amino
functional group may be masked as an amide, carbamate, imine, urea,
phosphenyl, phosphoryl or sulfenyl promoiety, which may be
hydrolyzed in vivo to provide the amino group. A carboxyl group may
be masked as an ester (including silyl esters and thioesters),
amide or hydrazide promoiety, which may be hydrolyzed in vivo to
provide the carboxyl group. Other specific examples of suitable
progroups and their respective promoieties will be apparent to
those of skill in the art.
[0066] "Progroup" refers to a type of protecting group that, when
used to mask a functional group within an active
2,4-pyrimidinediamine drug to form a promoiety, converts the drug
into a prodrug. Progroups are typically attached to the functional
group of the drug via bonds that are cleavable under specified
conditions of use. Thus, a progroup is that portion of a promoiety
that cleaves to release the functional group under the specified
conditions of use. As a specific example, an amide promoiety of the
formula --NH--C(O)CH.sub.3 comprises the progroup
--C(O)CH.sub.3.
[0067] "Proliferative disorder" refers to a disease or disorder
characterized by aberrant cell proliferation, for example where
cells divide more than their counterpart normal cells. The aberrant
proliferation may be caused by any mechanism of action or
combination of mechanisms of action. For example, the cell cycle of
one or more cells may be affected such that cell(s) divide more
frequently than their counterpart normal cells, or alternatively,
one or more cells may bypass inhibitory signals which would
normally limit their number of divisions. Proliferative diseases
include, but are not limited to, slow or fast growing tumors and
cancers.
[0068] "Antiproliferative compound" refers to a compound that
inhibits the proliferation of a cell as compared to an untreated
control cell of a similar type. The inhibition can be brought about
by any mechanism or combination of mechanisms, and may operate to
inhibit proliferation cytostatically or cytotoxically. As a
specific example, inhibition as used herein includes, but is not
limited to, arrest of cell division, a reduction in the rate of
cell division, proliferation and/or growth and/or induction of cell
death.
[0069] "Pharmaceutically effective amount" or "therapeutically
effective amount" refers to an amount of a compound sufficient to
treat a specified disorder or disease or one or more of its
symptoms and/or to prevent the occurrence of the disease or
disorder. In reference to tumorigenic proliferative disorders, a
pharmaceutically or therapeutically effective amount comprises an
amount sufficient to, among other things, cause the tumor to shrink
or to decrease the growth rate of the tumor.

[0215] Those of skill in the art will appreciate that the
2,4-pyrimidinediamine compounds described herein may include
functional groups that can be masked with progroups to create
prodrugs. Such prodrugs are usually, but need not be,
pharmacologically inactive until converted into their active drug
form. For example, ester groups commonly undergo acid-catalyzed
hydrolysis to yield the parent carboxylic acid when exposed to the
acidic conditions of the stomach, or base-catalyzed hydrolysis when
exposed to the basic conditions of the intestine or blood. Thus,
when administered to a subject orally, 2,4-pyrimidinediamines that
include ester moieties may be considered prodrugs of their
corresponding carboxylic acid, regardless of whether the ester form
is pharmacologically active.
[0216] In the prodrugs of the invention, any available functional
moiety may be masked with a progroup to yield a prodrug. Functional
groups within the 2,4-pyrimidinediamine compounds that may be
masked with progroups for inclusion in a promoiety include, but are
not limited to, amines (primary and secondary), hydroxyls,
sulfanyls (thiols), carboxyls, etc. Myriad progroups suitable for
masking such functional groups to yield promoieties that are
cleavable under the desired conditions of use are known in the art.
All of these progroups, alone or in combinations, may be included
in the prodrugs of the invention.
[0217] In one illustrative embodiment, the prodrugs are compounds
according to structural formulae (I)-(VI) in which R.sup.a, R.sup.b
and R.sup.c may be, in addition to their previously-defined
alternatives, a progroup.
[0218] In another illustrative embodiment, the prodrugs are
compounds according to structural formulae (I)-(VI) in which
R.sup.2' and R.sup.4' are each, independently of one another, a
progroup. Specific examples of progroups according to this
embodiment of the invention include, but are not limited to,
--C(O)CH.sub.3, --C(O)NHR.sup.h and --S(O).sub.2R.sup.h, where
R.sup.h is selected from the group consisting of lower alkyl,
(C5-C15) aryl and (C3-C8) cycloalkyl.
[0219] Those of skill in the art will appreciate that many of the
compounds and prodrugs described herein, as well as the various
compound species specifically described and/or illustrated herein,
may exhibit the phenomena of tautomerism, conformational isomerism,
geometric isomerism and/or optical isomerism. For example, the
compounds and prodrugs may include one or more chiral centers
and/or double bonds and as a consequence may exist as
stereoisomers, such as double-bond isomers (i.e., geometric
isomers), enantiomers and diasteromers and mixtures thereof, such
as racemic mixtures. As another example, the compounds and prodrugs
may exist in several tautomeric forms, including the enol form, the
keto form and mixtures thereof. As the various compound names,
formulae and compound drawings within the specification and claims
can represent only one of the possible tautomeric, conformational
isomeric, optical isomeric or geometric isomeric forms, it should
be understood that the invention encompasses any tautomeric,
conformational isomeric, optical isomeric and/or geometric isomeric
forms of the compounds or prodrugs having one or more of the
utilities described herein, as well as mixtures of these various
different isomeric forms. In cases of limited rotation around the
2,4-pryimidinediamine core structure, atrop isomers are also
possible and are also specifically included in the compounds and/or
prodrugs of the invention.
[0220] Depending upon the nature of the various substituents, the
2,4-pyrimidinediamine compounds and prodrugs may be in the form of
salts. Such salts include salts suitable for pharmaceutical uses
("pharmaceutically-acceptable salts"), salts suitable for
veterinary uses, etc. Such salts may be derived from acids or
bases, as is well-known in the art.
[0221] In some embodiments, the salt is a pharmaceutically
acceptable salt. Generally, pharmaceutically acceptable salts are
those salts that retain substantially one or more of the desired
pharmacological activities of the parent compound and which are
suitable for administration to humans. Pharmaceutically acceptable
salts include acid addition salts formed with inorganic acids or
organic acids. Inorganic acids suitable for forming
pharmaceutically acceptable acid addition salts include, by way of
example and not limitation, hydrohalide acids (e.g., hydrochloric
acid, hydrobromic acid, hydriodic, etc.), sulfuric acid, nitric
acid, phosphoric acid, and the like. Organic acids suitable for
forming pharmaceutically acceptable acid addition salts include, by
way of example and not limitation, acetic acid, trifluoroacetic
acid, propionic acid, hexanoic acid, cyclopentanepropionic acid,
glycolic acid, oxalic acid, pyruvic acid, lactic acid, malonic
acid, succinic acid, malic acid, maleic acid, fumaric acid,
tartaric acid, citric acid, palmitic acid, benzoic acid,
3-(4-hydroxybenzoyl)benzoic acid, cinnamic acid, mandelic acid,
alkylsulfonic acids (e.g., methanesulfonic acid, ethanesulfonic
acid, 1,2-ethane-disulfonic acid, 2-hydroxyethanesulfonic acid,
etc.), arylsulfonic acids (e.g., benzenesulfonic acid,
4-chlorobenzenesulfonic acid, 2-naphthalenesulfonic acid,
4-toluenesulfonic acid, camphorsulfonic acid, etc.),
4-methylbicyclo[2.2.2]-oct-2-ene-1-carboxylic acid, glucoheptonic
acid, 3-phenylpropionic acid, trimethylacetic acid, tertiary
butylacetic acid, lauryl sulfuric acid, gluconic acid, glutamic
acid, hydroxynaphthoic acid, salicylic acid, stearic acid, muconic
acid, and the like.
[0222] Pharmaceutically acceptable salts also include salts formed
when an acidic proton present in the parent compound is either
replaced by a metal ion (e.g., an alkali metal ion, an alkaline
earth metal ion or an aluminum ion) or coordinates with an organic
base (e.g., ethanolamine, diethanolamine, triethanolamine,
N-methylglucamine, morpholine, piperidine, dimethylamine,
diethylamine, etc.).
[0223] The 2,4-pyrimidinediamine compounds and prodrugs, as well as
the salts thereof, may also be in the form of hydrates, solvates
and N-oxides, as are well-known in the art.
[0224] 5.3 Methods of Synthesis
[0225] The 2,4-pyrimidinediamine compounds and prodrugs may be
synthesized via a variety of different synthetic routes using
commercially available starting materials and/or starting materials
prepared by conventional synthetic methods. Suitable exemplary
methods that may be routinely adapted to synthesize the
2,4-pyrimidinediamine compounds and prodrugs are found in U.S. Pat.
No. 5,958,935, the disclosure of which is incorporated herein by
reference. Specific examples describing the synthesis of numerous
2,4-pyrimidinediamine compounds and prodrugs, as well as
intermediates therefor, are described in copending U.S. application
Ser. No. 10/355,543, filed Jan. 31, 2003 (U.S. 2004-0029902
published Feb. 12, 2004), WO 03/63794, copending U.S. application
Ser. No. 10/631,029, filed Jul. 29, 2003, WO 2004/014312, copending
application Ser. No. ______ filed Jul. 30, 2004 (identified by
attorney docket no. 28575/US/US/US) and international application
no. ______, filed Jul. 30, 2004 (identified by attorney docket no.
28575/US/US/PCT), the contents of which are incorporated herein by
reference. All of the compounds described herein (including
prodrugs) can be prepared according to, or by routine adaptation
of, these various methods.
[0226] A variety of exemplary synthetic routes that can be used to
synthesize the 2,4-pyrimidinediamine compounds and prodrugs are
described in Schemes (I)-(XI), below. In Schemes (I)-(XI),
like-numbered compounds have similar structures. These methods may
be routinely adapted to synthesize the corresponding N2- and/or
N4-alkylated compounds and prodrugs, as illustrated in Scheme
(XII).
[0227] In one exemplary embodiment, the compounds can be
synthesized from substituted or unsubstituted uracils or
thiouracils as illustrated in Scheme (I), below: 736
[0228] In Scheme (I), R.sup.2, R.sup.4, R.sup.5, R.sup.6, L.sup.1
and L.sup.2 are as previously defined for structural formulae (I),
X is a halogen (e.g., F, Cl, Br or I) and G and G' are each,
independently of one another, selected from the group consisting of
O and S. Referring to Scheme (I), uracil or thiouracil 2 is
dihalogenated at the 2- and 4-positions using standard halogenating
agent POX.sub.3 (or other standard halogenating agent) under
standard conditions to yield 2,4-bishalo pyrimidine 4. Depending
upon the R.sup.5 substituent, in pyrimidine 4, the halide at the C4
position is more reactive towards nucleophiles than the halide at
the C2 position. This differential reactivity can be exploited to
synthesize 2,4-pyrimidinediamines according structural formulae (I)
by first reacting 2,4-bishalopyrimidine 4 with one equivalent of
amine 10, yielding 4N-substituted-2-halo-4-pyrim- idineamine 8,
followed by amine 6 to yield a 2,4-pyrimidinediamine according
structural formulae (I). 2N,4N-bis(substituted)-2,4-pyrimidined-
iamines 12 and 14 can be obtained by reacting 2,4-bishalopyrimidine
4 with excess 6 or 10, respectively.
[0229] In most situations, the C4 halide is more reactive towards
nucleophiles, as illustrated in the Scheme. However, as will be
recognized by skilled artisans, the identity of the R.sup.5
substituent may alter this reactivity. For example, when R.sup.5 is
trifluoromethyl, a 50:50 mixture of
4N-substituted-4-pyrimidineamine 8 and the corresponding
2N-substituted-2-pyrimidineamine is obtained. Regardless of the
identity of the R.sup.5 substituent, the regioselectivity of the
reaction can be controlled by adjusting the solvent and other
synthetic conditions (such as temperature), as is well-known in the
art.
[0230] The reactions depicted in Scheme (I) may proceed more
quickly when the reaction mixtures are heated via microwave. When
heating in this fashion, the following conditions may be used: heat
to 175.degree. C. in ethanol for 5-20 min. in a Smith Reactor
(Personal Chemistry) in a sealed tube (at 20 bar pressure).
[0231] The uracil or thiouracil 2 starting materials may be
purchased from commercial sources or prepared using standard
techniques of organic chemistry. Commercially available uracils and
thiouracils that can be used as starting materials in Scheme (I)
include, by way of example and not limitation, uracil (Aldrich
#13,078-8; CAS Registry 66-22-8); 2-thio-uracil (Aldrich #11,558-4;
CAS Registry 141-90-2); 2,4-dithiouracil (Aldrich #15,846-1; CAS
Registry 2001-93-6); 5-bromouracil (Aldrich #85,247-3; CAS Registry
51-20-7; 5-fluorouracil (Aldrich #85,847-1; CAS Registry 51-21-8);
5-iodouracil (Aldrich #85,785-8; CAS Registry 696-07-1);
5-nitrouracil (Aldrich #85,276-7; CAS Registry 611-08-5);
5-(trifluoromethyl)-uracil (Aldrich #22,327-1; CAS Registry
54-20-6). Additional 5-substituted uracils and/or thiouracils are
available from General Intermediates of Canada, Inc., Edmonton,
Calif. (www.generalintermediates.com) and/or Interchim, Cedex,
France (www.interchim.com), or may be prepared using standard
techniques. Myriad textbook references teaching suitable synthetic
methods are provided infra.
[0232] Amines 6 and 10 may be purchased from commercial sources or,
alternatively, may be synthesized utilizing standard techniques.
For example, suitable amines may be synthesized from nitro
precursors using standard chemistry. Specific exemplary reactions
are provided in the Examples section. See also Vogel, 1989,
Practical Organic Chemistry, Addison Wesley Longman, Ltd. and John
Wiley & Sons, Inc.
[0233] Skilled artisans will recognize that in some instances,
amines 6 and 10 and/or substituents R.sup.5 and/or R.sup.6 on
uracil or thiouracil 2 may include functional groups that require
protection during synthesis. The exact identity of any protecting
group(s) used will depend upon the identity of the functional group
being protected, and will be apparent to these of skill in the art.
Guidance for selecting appropriate protecting groups, as well as
synthetic strategies for their attachment and removal, may be
found, for example, in Greene & Wuts, Protective Groups in
Organic Synthesis, 3d Edition, John Wiley & Sons, Inc., New
York (1999) and the references cited therein (hereinafter "Greene
& Wuts").
[0234] A specific embodiment of Scheme (I) utilizing 5-fluorouracil
(Aldrich #32,937-1) as a starting material is illustrated in Scheme
(II), below: 737
[0235] In Scheme (II), R.sup.2, R.sup.4, L.sup.1 and L.sup.2 are as
previously defined for Scheme (I). According to Scheme (II),
5-fluorouracil 3 is halogenated with POCl.sub.3 to yield
2,4-dichloro-5-fluoropyrimidine 5, which is then reacted with
excess amine 6 or 10 to yield N2,N4-bis substituted
5-fluoro-2,4-pyrimidinediami- ne 11 or 13, respectively.
Alternatively, non-bis-2N,4N-disubstituted-5-fl-
uoro-2,4-pyrimidinediamine 9 may be obtained by reacting
2,4-dichloro-5-fluoropyrimidine 5 with one equivalent of amine 10
(to yield 2-chloro-N-4-substituted-5-fluoro-4-pyrimidineamine 7)
followed by one or more equivalents of amine 6.
[0236] In another exemplary embodiment, the 2,4-pyrimidinediamine
compounds of the invention may be synthesized from substituted or
unsubstituted cytosines as illustrated in Schemes (IIa) and (IIb),
below: 738 739
[0237] In Schemes (IIa) and (IIb), R.sup.2, R.sup.4, R.sup.5,
R.sup.6, L.sup.1, L.sup.2 and X are as previously defined for
Scheme (I) and PG represents a protecting group. Referring to
Scheme (IIa), the C4 exocyclic amine of cytosine 20 is first
protected with a suitable protecting group PG to yield N4-protected
cytosine 22. For specific guidance regarding protecting groups
useful in this context, see Vorbruggen and Ruh-Pohlenz, 2001,
Handbook of Nucleoside Synthesis, John Wiley & Sons, NY, pp.
1-631 ("Vorbruggen"). Protected cytosine 22 is halogenated at the
C2 position using a standard halogenation reagent under standard
conditions to yield 2-chloro-4N-protected-4-pyrimidineamin- e 24.
Reaction with amine 6 followed by deprotection of the C4 exocyclic
amine and reaction with amine 10 yields a 2,4-pyrimidinediamine
according to structural formulae (I).
[0238] Alternatively, referring to Scheme (IIb), cytosine 20 may be
reacted with amine 10 or protected amine 21 to yield N4-substituted
cytosine 23 or 27, respectively. These substituted cytosines may
then be halogenated as previously described, deprotected (in the
case of N4-substituted cytosine 27) and reacted with amine 6 to
yield a 2,4-pyrimidinediamine according to structural formulae
(I).
[0239] Commercially-available cytosines that may be used as
starting materials in Schemes (IIa) and (IIb) include, but are not
limited to, cytosine (Aldrich #14,201-8; CAS Registry 71-30-7);
N4-acetylcytosine (Aldrich #37,791-0; CAS Registry 14631-20-0);
5-fluorocytosine (Aldrich #27,159-4; CAS Registry 2022-85-7); and
5-(trifluoromethyl)-cytosine. Other suitable cytosines useful as
starting materials in Schemes (IIa) are available from General
Intermediates of Canada, Inc., Edmonton, Calif.
(www.generalintermediates.com) and/or Interchim, Cedex, France
(www.interchim.com), or may be prepared using standard techniques.
Myriad textbook references teaching suitable synthetic methods are
provided infra.
[0240] In still another exemplary embodiment, the
2,4-pyrimidinediamine compounds may be synthesized from substituted
or unsubstituted 2-amino-4-pyrimidinols as illustrated in Scheme
(III), below: 740
[0241] In Scheme (III), R.sup.2, R.sup.4, R.sup.5, R.sup.6,
L.sup.1, L.sup.2 and X are as previously defined for Scheme (I) and
Z is a leaving group as discussed in more detail in connection with
Scheme IV, infra. Referring to Scheme (III), 2-amino-4-pyrimidinol
30 is reacted with amine 6 (or optionally protected amine 21) to
yield N2-substituted-4-pyrimidino- l 32, which is then halogenated
as previously described to yield
N2-substituted-4-halo-2-pyrimidineamine 34. Optional deprotection
(for example if protected amine 21 was used in the first step)
followed by reaction with amine 10 affords a 2,4-pyrimidinediamine
according to structural formulae (I). Alternatively, pyrimidinol 30
can be reacted with acylating agent 31.
[0242] Suitable commercially-available 2-amino-4-pyrimidinols 30
that can be used as starting materials in Scheme (III) are
available from General Intermediates of Canada, Inc., Edmonton,
Calif. (www.generalintermediates- .com) and/or Interchim, Cedex,
France (www.interchim.com), or may be prepared using standard
techniques. Myriad textbook references teaching suitable synthetic
methods are provided infra.
[0243] Alternatively, the 2,4-pyrimidinediamine compounds may be
prepared from substituted or unsubstituted 4-amino-2-pyrimidinols
as illustrated in Scheme (IV), below: 741
[0244] In Scheme (IV), R.sup.2, R.sup.4, R.sup.5, R.sup.6, L.sup.1
and L.sup.2 are as previously defined for Scheme (I) and Z
represents a leaving group. Referring to Scheme (IV), the
C2-hydroxyl of 4-amino-2-pyrimidinol 40 is more reactive towards
nucleophiles than the C4-amino such that reaction with amine 6
yields N2-substituted-2,4-pyrimi- dinediamine 42. Subsequent
reaction with compound 44, which includes a good leaving group Z,
or amine 10 yields a 2,4-pyrimidinediamine according to structural
formulae (I). Compound 44 may include virtually any leaving group
that can be displaced by the C4-amino of
N2-substituted-2,4-pyrimidinediamine 42. Suitable leaving groups Z
include, but are not limited to, halogens, methanesulfonyloxy
(mesyloxy; "OMs"), trifluoromethanesulfonyloxy ("OTf") and
p-toluenesulfonyloxy (tosyloxy; "OTs"), benzene sulfonyloxy
("besylate") and metanitro benzene sulfonyloxy ("nosylate"). Other
suitable leaving groups will be apparent to those of skill in the
art.
[0245] Substituted 4-amino-2-pyrimidinol starting materials may be
obtained commercially or synthesized using standard techniques.
Myriad textbook references teaching suitable synthetic methods are
provided infra.
[0246] In still another exemplary embodiment, the
2,4-pyrimidinediamine compounds can be prepared from
2-chloro-4-aminopyrimidines or 2-amino-4-chloropyrimidines as
illustrated in Scheme (V), below: 742
[0247] In Scheme (V), R.sup.2, R.sup.4, R.sup.5, R.sup.6, L.sup.1,
L.sup.2 and X are as defined for Scheme (I) and Z is as defined for
Scheme (IV). Referring to Scheme (V), 2-amino-4-chloropyrimidine 50
is reacted with amino 10 to yield 4N-substituted-2-pyrimidineamine
52 which, following reaction with compound 31 or amine 6, yields a
2,4-pyrimidinediamine according to structural formulae (I).
Alternatively, 2-chloro-4-amino-pyrimidine 54 may be reacted with
compound 44 followed by amine 6 to yield a compound according to
structural formulae (I).
[0248] A variety of pyrimidines 50 and 54 suitable for use as
starting materials in Scheme (V) are commercially available from
General Intermediates of Canada, Inc., Edmonton, Calif.
(www.generalintermediates- .com) and/or Interchim, Cedex, France
(www.interchim.com), or may be prepared using standard techniques.
Myriad textbook references teaching suitable synthetic methods are
provided infra.
[0249] Alternatively, 4-chloro-2-pyrimidineamines 50 may be
prepared as illustrated in Scheme (Va): 743
[0250] In Scheme (Va), R.sup.5 and R.sup.6 are as previously
defined for structural formulae (I). In Scheme (Va), dicarbonyl 53
is reacted with guanidine to yield 2-pyrimidineamine 51. Reaction
with peracids like m-chloroperbenzoic acid, trifluoroperacetic acid
or urea hydrogen peroxide complex yields N-oxide 55, which is then
halogenated to give 4-chloro-2-pyrimidineamine 50. The
corresponding 4-halo-2-pyrimidineamine- s may be obtained by using
suitable halogenation reagents.
[0251] In yet another exemplary embodiment, the
2,4-pyrimidinediamine compounds can be prepared from substituted or
unsubstituted uridines as illustrated in Scheme (VI), below:
744
[0252] In Scheme (VI), R.sup.2, R.sup.4, R.sup.5, R.sup.6, L.sup.1,
L.sup.2 and X are as previously defined for Scheme (I) and the
superscript PG represents a protecting group, as discussed in
connection with Scheme (IIb). According to Scheme (VI), uridine 60
has a C4 reactive center such that reaction with amine 10 or
protected amine 21 yields N4-substituted cytidine 62 or 64,
respectively. Acid-catalyzed deprotection of N4-substituted 62 or
64 (when "PG" represents an acid-labile protecting group) yields
N4-substituted cytosine 28, which may be subsequently halogenated
at the C2-position and reacted with amine 6 to yield a
2,4-pyrimidinediamine according to structural formulae (I).
[0253] Cytidines may also be used as starting materials in an
analogous manner, as illustrated in Scheme (VII), below: 745
[0254] In Scheme (VI), R.sup.2, R.sup.4, R.sup.5, R.sup.6, L.sup.1,
L.sup.2 and X are as previously defined in Scheme (I) and the
superscript PG represents a protecting group as discussed above.
Referring to Scheme (VII), like uridine 60, cytidine 70 has a C4
reactive center such that reaction with amine 10 or protected amine
21 yields N4-substituted cytidine 62 or 64, respectively. These
cytidines 62 and 64 are then treated as previously described for
Scheme (VI) to yield a 2,4-pyrimidinediamine according to
structural formulae (I).
[0255] Although Schemes (VI) and (VII) are exemplified with
ribosylnucleosides, skilled artisans will appreciate that the
corresponding 2'-deoxyribo and 2',3'-dideoxyribo nucleosides, as
well as nucleosides including sugars or sugar analogs other than
ribose, would also work.
[0256] Numerous uridines and cytidines useful as starting materials
in Schemes (VI) and (VII) are known in the art, and include, by way
of example and not limitation, 5-trifluoromethyl-2'-deoxycytidine
(Chem. Sources #ABCR F07669; CAS Registry 66,384-66-5);
5-bromouridine (Chem. Sources Int'l 2000; CAS Registry 957-75-5);
5-iodo-2'-deoxyuridine (Aldrich #1-775-6; CAS Registry 54-42-2);
5-fluorouridine (Aldrich #32,937-1; CAS Registry 316-46-1);
5-iodouridine (Aldrich #85,259-7; CAS Registry 1024-99-3);
5-(trifluoromethyl)uridine (Chem. Sources Int'l 2000; CAS Registry
70-00-8); 5-trifluoromethyl-2'-deoxyuridine (Chem. Sources Int'l
2000; CAS Registry 70-00-8). Additional uridines and cytidines that
can be used as starting materials in Schemes (VI) and (VII) are
available from General Intermediates of Canada, Inc., Edmonton,
Calif. (www.generalintermediates.com) and/or Interchim, Cedex,
France (www.interchim.com), or may be prepared using standard
techniques. Myriad textbook references teaching suitable synthetic
methods are provided infra.
[0257] As will be recognized by skilled artisans, certain
2,4-pyrimidinediamines compounds synthesized via the exemplary
methods described above, or by other well-known means, may also be
utilized as starting materials and/or intermediates to synthesize
additional 2,4-pyrimidinediamine compounds. A specific example is
illustrated in Scheme (VIII), below: 746
[0258] In Scheme (VIII), R.sup.4, R.sup.5, R.sup.6, L.sup.2, Y,
R.sup.a and R.sup.c are as previously defined for structural
formulae (I). Each R.sup.a' is independently an R.sup.a, and may be
the same or different from the illustrated R.sup.a. Referring to
Scheme (VIII), carboxylic acid or ester 100 may be converted to
amide 104 by reaction with amine 102. In amine 102, R.sup.a' may be
the same or different than R.sup.a of acid or ester 100. Similarly,
carbonate ester 106 may be converted to carbamate 108.
[0259] A second specific example is illustrated in Scheme (IX),
below: 747
[0260] In Scheme (IX) R.sup.4, R.sup.5, R.sup.6, L.sup.2, Y and
R.sup.c are as previously defined for structural formulae (I).
Referring to Scheme (IX), amide 110 or 116 may be converted to
amine 114 or 118, respectively, by borane reduction with borane
methylsulfide complex 112. Other suitable reactions for
synthesizing 2,4-pyrimidinediamine compounds from
2,4-pyrimidinediamine starting materials will be apparent to those
of skill in the art.
[0261] Compounds including alkyl groups at the amine groups at the
2- and/or 4-position of the 2,4-pyrimidinediamine ring can be
prepared using routine alkylation procedures. An exemplary scheme
for selectively methylating the amine group at the 4-position of
the 2,4-pyrimidinediamine is illustrated in Scheme (XII): 748
[0262] In Scheme (XII), L.sup.1, L.sup.2, R.sup.2, R.sup.4, R.sup.5
and R.sup.6 are as previously defined for structural formula (I).
The above Scheme can be routinely adapted to synthesize other
N-alkylated compounds.
[0263] Compounds that are entiomerically or diasteriomerically pure
can be synthesized via chiral-specific syntheses utilizing
enantiomerically or diasteriomerically pure starting reagents as is
known in the art. Alternatively, specified enatiomers,
diastereomers and/or mixtures thereof can be isolated utilizing
conventional chiral separation techniques.
[0264] Although many of the synthetic schemes discussed above do
not illustrate the use of protecting groups, skilled artisans will
recognize that in some instances certain substituents, such as, for
example, R.sup.2 and/or R.sup.4, may include functional groups
requiring protection. The exact identity of the protecting group
used will depend upon, among other things, the identity of the
functional group being protected and the reaction conditions used
in the particular synthetic scheme, and will be apparent to those
of skill in the art. Guidance for selecting protecting groups and
chemistries for their attachment and removal suitable for a
particular application can be found, for example, in Greene &
Wuts, supra.
[0265] Prodrugs as described herein may be prepared by routine
modification of the above-described methods. Alternatively, such
prodrugs may be prepared by reacting a suitably protected
2,4-pyrimidinediamine of structural formula (I), (II), (III), (IV)
and/or (V) with a suitable progroup. Conditions for carrying out
such reactions and for deprotecting the product to yield a prodrugs
as described herein are well-known.

[0267] 5.4 Activity of the Antiproliferative Compounds
[0268] Active 2,4-pyrimidinediamine compounds typically inhibit
proliferation of desired cells, such as tumor cells, with an
IC.sub.50 in the range of about 1 mM or less, as measured in a
standard in vitro cellular proliferation assay. Of course, skilled
artisans will appreciate that compounds which exhibit lower
IC.sub.50s, for example on the order of 100 .mu.M, 20 .mu.M, 10
.mu.M, 1 .mu.M, 100 nM, 10 nM, 1 nM, or even lower, may be
particularly useful in therapeutic applications. The
antiprolierative activity may be cytostatic or it may be cytotoxic.
In instances where antiproliferative activity specific to a
particular cell type is desired, the compound may be assayed for
activity with the desired cell type and counter-screened for a lack
of activity against other cell types. The desired degree of
"inactivity" in such counter screens, or the desired ratio of
activity vs. inactivity may vary for different situations, and may
be selected by the user.
[0269] 5.5 Uses of the Antiproliferative Compounds
[0270] The antiproliferative 2,4-pyrimidinediamine compounds,
including the various salts, prodrugs, hydrates and N-oxide forms
thereof, may be used to inhibit cell proliferation in a variety of
contexts. According to some embodiments of the method, a cell or
population of cells is contacted with an amount of such a compound
effective to inhibit proliferation of the cell or cell population.
The compound may act cytotoxically to kill the cell, or
cytostatically to inhibit proliferation without killing the
cell.
[0271] In some embodiments, the methods may be practiced as a
therapeutic approach towards the treatment of proliferative
disorders. Thus, in a specific embodiment, the
2,4-pyrimidinediamine compounds (and the various forms described
herein) may be used to treat proliferative disorders in animal
subjects, including humans. The method generally comprises
administering to the subject an amount of a compound of the
invention, or a salt, prodrug, hydrate or N-oxide thereof,
effective to treat the disorder. In one embodiment, the subject is
a mammal, including, but not limited to, bovine, horse, feline,
canine, rodent, or primate. In another embodiment, the subject is a
human.
[0272] A variety of cellular proliferative disorders may be treated
with the compounds of the present invention. In one embodiment, the
compounds are used to treat various cancers in afflicted subjects.
Cancers are traditionally classified based on the tissue and cell
type from which the cancer cells originate. Carcinomas are
considered cancers arising from epithelial cells while sarcomas are
considered cancers arising from connective tissues or muscle. Other
cancer types include leukemias, which arise from hematopoietic
cells, and cancers of nervous system cells, which arise from neural
tissue. For non-invasive tumors, adenomas are considered benign
epithelial tumors with glandular organization while chondomas are
benign tumor arising from cartilage. In the present invention, the
described compounds may be used to treat proliferative disorders
encompassed by carcinomas, sarcomas, leukemias, neural cell tumors,
and non-invasive tumors.
[0273] In a specific embodiment, the compounds are used to treat
solid tumors arising from various tissue types, including, but not
limited to, cancers of the bone, breast, respiratory tract (e.g.,
bladder), brain reproductive organs, digestive tract, urinary
tract, eye, liver, skin, head, neck, thyroid, parathyroid, and
mestastatic forms thereof.
[0274] Specific proliferative disorders include the following: a)
proliferative disorders of the breast include, but are not limited
to, invasive ductal carcinoma, invasive lobular carcinoma, ductal
carcinoma, lobular carcinoma in situ, and metastatic breast cancer;
b) proliferative disorders of the skin include, but are not limited
to, basal cell carcinoma, squamous cell carcinoma, malignant
melanoma, and Karposi's sarcoma; c) proliferative disorders of the
respiratory tract include, but are not limited to, small cell and

[0275] It is to be understood that the descriptions of
proliferative disorders is not limited to the conditions described
above, but encompasses other disorders characterized by
uncontrolled growth and malignancy. It is further understood that
proliferative disorders include various metastatic forms of the
tumor and cancer types described herein. The compounds of the
present invention may be tested for effectiveness against the
disorders described herein, and a therapeutically effective regimen
established. Effectiveness, as further described below, includes
reduction or remission of the tumor, decreases in the rate of cell
proliferation, or cytostatic or cytotoxic effect on cell
growth.
[0276] 5.6 Combination Therapies
[0277] The compounds of the present invention may be used alone, in
combination with one another, or as an adjunct to, or in
conjunction with, other established antiproliferative therapies.
Thus, the compounds of the present invention may be used with
traditional cancer therapies, such as ionization radiation in the
form of .gamma.-rays and x-rays, delivered externally or internally
by implantation of radioactive compounds, and as a follow-up to
surgical removal of tumors.
[0278] In another aspect, the compounds of the present invention
may be used with other chemotherapeutic agents useful for the
disorder or condition being treated. These compounds may be
administered simultaneously, sequentially, by the same route of
administration, or by a different route.
[0279] In one embodiment, the present compounds may be used with
other anti-cancer or cytotoxic agents. Various classes of
anti-cancer and anti-neoplastic compounds include, but are not
limited to, alkylating agents, antimetabolites, vinca alkyloids,
taxanes, antibiotics, enzymes, cytokines, platinum coordination
complexes, substituted ureas, tyrosine kinase inhibitors, hormones
and hormone antagonists. Exemplary alkylating agents include, by
way of example and not limitation, mechlorothamine,
cyclophosphamide, ifosfamide, melphalan, chlorambucil,
ethyleneimines, methylmelamines, alkyl sulfonates (e.g., busulfan),
and carmustine. Exemplary antimetabolites include, by way of
example and not limitation, folic acid analog methotrexate;
pyrmidine analog fluorouracil, cytosine arbinoside; purine analogs
mecaptopurine, thioguanine, and azathioprine. Exemplary vinca
alkyloids include, by way of example and not limitation,
vinblastine, vincristine, paclitaxel, and colchicine. Exemplary
antibiotics include, by way of example and not limitation,
actinomycin D, daunorubicin, and bleomycin. An exemplary enzyme
effective as anti-neoplastic agents include L-asparaginase.
Exemplary coordination compounds include, by way of example and not
limitation, cisplatin and carboplatin. Exemplary hormones and
hormone related compounds include, by way of example and not
limitation, adrenocorticosteroids prednisone and dexamethasone;
aromatase inhibitors amino glutethimide, formestane, and
anastrozole; progestin compounds hydroxyprogesteron caproate,
medroxyprogesterone; and anti-estrogen compound tamoxifen.
[0280] These and other useful anti-cancer compounds are described
in Merck Index, 13th Ed. (O'Neil M. J. et al., ed) Merck Publishing
Group (2001) and Goodman and Gilmans The Pharmacological Basis of
Therapeutics, 10th Edition, Hardman, J. G. and Limbird, L. E. eds.,
pg. 1381-1287, McGraw Hill, (1996), both of which are incorporated
by reference herein.
[0281] Addtional anti-proliferative compounds useful in combination
with the compounds of the present invention include, by way of
example and not limitation, antibodies directed against growth
factor receptors (e.g., anti-Her2); antibodies for activating T
cells (e.g., anti-CTLA-4 antibodies); and cytokines such as
interferon-.alpha. and interferon-.gamma., interleukin-2, and
GM-CSF.
[0282] 5.7 Formulations and Administration
[0283] When used to treat or prevent such diseases, the active
compounds may be administered singly, as mixtures of one or more
active compounds or in mixture or combination with other agents
useful for treating such diseases and/or the symptoms associated
with such diseases. The active compounds may also be administered
in mixture or in combination with agents useful to treat other
disorders or maladies, such as steroids, membrane stablizers. The
active compounds or prodrugs may be administered per se, or as
pharmaceutical compositions, comprising an active compound or
prodrug.
[0284] Pharmaceutical compositions comprising the active compounds
of the invention (or prodrugs thereof) may be manufactured by means
of conventional mixing, dissolving, granulating, dragee-making
levigating, emulsifying, encapsulating, entrapping or
lyophilization processes. The compositions may be formulated in
conventional manner using one or more physiologically acceptable
carriers, diluents, excipients or auxiliaries which facilitate
processing of the active compounds into preparations which can be
used pharmaceutically (see Remingtons's Pharmaceutical Sciences,
15.sup.th Ed., Hoover, J. E. ed., Mack Publishing Co. (2003)
[0285] The active compound or prodrug may be formulated in the
pharmaceutical compositions per se, or in the form of a hydrate,
solvate, N-oxide or pharmaceutically acceptable salt, as previously
described. Typically, such salts are more soluble in aqueous
solutions than the corresponding free acids and bases, but salts
having lower solubility than the corresponding free acids and bases
may also be formed.
[0286] Pharmaceutical compositions of the invention may take a form
suitable for virtually any mode of administration, including, for
example, topical, ocular, oral, buccal, systemic, nasal, injection,
transdermal, rectal, vaginal, etc., or a form suitable for
administration by inhalation or insufflation.
[0287] For topical administration, the active compound(s) or
prodrug(s) may be formulated as solutions, gels, ointments, creams,
suspensions, etc. as are well-known in the art.
[0288] Systemic formulations include those designed for
administration by injection, e.g., subcutaneous, intravenous,
intramuscular, intrathecal or intraperitoneal injection, as well as
those designed for transdermal, transmucosal oral or pulmonary
administration.
[0289] Useful injectable preparations include sterile suspensions,
solutions or emulsions of the active compound(s) in aqueous or oily
vehicles. The compositions may also contain formulating agents,
such as suspending, stabilizing and/or dispersing agent. The
formulations for injection may be presented in unit dosage form,
e.g., in ampules or in multidose containers, and may contain added
preservatives.
[0290] Alternatively, the injectable formulation may be provided in
powder form for reconstitution with a suitable vehicle, including
but not limited to sterile pyrogen free water, buffer, dextrose
solution, etc., before use. To this end, the active compound(s) may
be dried by any art-known technique, such as lyophilization, and
reconstituted prior to use.
[0291] For transmucosal administration, penetrants appropriate to
the barrier to be permeated are used in the formulation. Such
penetrants are known in the art.
[0292] For oral administration, the pharmaceutical compositions may
take the form of, for example, lozenges, tablets or capsules
prepared by conventional means with pharmaceutically acceptable
excipients such as binding agents (e.g., pregelatinised maize
starch, polyvinylpyrrolidone or hydroxypropyl methylcellulose);
fillers (e.g., lactose, microcrystalline cellulose or calcium
hydrogen phosphate); lubricants (e.g., magnesium stearate, talc or
silica); disintegrants (e.g., potato starch or sodium starch
glycolate); or wetting agents (e.g., sodium lauryl sulfate,
lecithin). The tablets may be coated by methods well known in the
art with, for example, sugars, films or enteric coatings.
[0293] Liquid preparations for oral administration may take the
form of, for example, elixirs, solutions, syrups or suspensions, or
they may be presented as a dry product for constitution with water
or other suitable vehicle before use. Such liquid preparations may
be prepared by conventional means with pharmaceutically acceptable
additives such as suspending agents (e.g., sorbitol syrup,
cellulose derivatives or hydrogenated edible fats); emulsifying
agents (e.g., lecithin or acacia); non-aqueous vehicles (e.g.,
almond oil, oily esters, ethyl alcohol, cremophore.TM. or
fractionated vegetable oils); and preservatives (e.g., methyl or
propyl-p-hydroxybenzoates or sorbic acid). The preparations may
also contain buffer salts, preservatives, flavoring, coloring and
sweetening agents as appropriate.
[0294] Preparations for oral administration may be suitably
formulated to give controlled release of the active compound or
prodrug, as is well known.
[0295] For buccal administration, the compositions may take the
form of tablets or lozenges formulated in conventional manner.
[0296] For rectal and vaginal routes of administration, the active
compound(s) may be formulated as solutions (for retention enemas)
suppositories or ointments containing conventional suppository
bases such as cocoa butter or other glycerides.
[0297] For nasal administration or administration by inhalation or
insufflation, the active compound(s) or prodrug(s) can be
conveniently delivered in the form of an aerosol spray from
pressurized packs or a nebulizer with the use of a suitable
propellant, e.g., dichlorodifluoromethane, trichlorofluoromethane,
dichlorotetrafluoroethan- e, fluorocarbons, carbon dioxide or other
suitable gas. In the case of a pressurized aerosol, the dosage unit
may be determined by providing a valve to deliver a metered amount.
Capsules and cartridges for use in an inhaler or insufflator (for
example capsules and cartridges comprised of gelatin) may be
formulated containing a powder mix of the compound and a suitable
powder base such as lactose or starch.
[0298] For ocular administration, the active compound(s) or
prodrug(s) may be formulated as a solution, emulsion, suspension,
etc. suitable for administration to the eye. A variety of vehicles
suitable for administering compounds to the eye are known in the
art. Specific non-limiting examples are described in U.S. Pat. No.
6,261,547; U.S. Pat. No. 6,197,934; U.S. Pat. No. 6,056,950; U.S.
Pat. No. 5,800,807; U.S. Pat. No. 5,776,445; U.S. Pat. No.
5,698,219; U.S. Pat. No. 5,521,222; U.S. Pat. No. 5,403,841; U.S.
Pat. No. 5,077,033; U.S. Pat. No. 4,882,150; and U.S. Pat. No.
4,738,851.
[0299] For prolonged delivery, the active compound(s) or prodrug(s)
can be formulated as a depot preparation for administration by
implantation or intramuscular injection. The active ingredient may
be formulated with suitable polymeric or hydrophobic materials
(e.g., as an emulsion in an acceptable oil) or ion exchange resins,
or as sparingly soluble derivatives, e.g., as a sparingly soluble
salt. Alternatively, transdermal delivery systems manufactured as
an adhesive disc or patch which slowly releases the active
compound(s) for percutaneous absorption may be used. To this end,
permeation enhancers may be used to facilitate transdermal
penetration of the active compound(s). Suitable transdermal patches
are described in for example, U.S. Pat. No. 5,407,713; U.S. Pat.
No. 5,352,456; U.S. Pat. No. 5,332,213; U.S. Pat. No. 5,336,168;
U.S. Pat. No. 5,290,561; U.S. Pat. No. 5,254,346; U.S. Pat. No.
5,164,189; U.S. Pat. No. 5,163,899; U.S. Pat. No. 5,088,977; U.S.
Pat. No. 5,087,240; U.S. Pat. No. 5,008,110; and U.S. Pat. No.
4,921,475.
[0300] Alternatively, other pharmaceutical delivery systems may be
employed. Liposomes and emulsions are well-known examples of
delivery vehicles that may be used to deliver active compound(s) or
prodrug(s). Certain organic solvents such as dimethylsulfoxide
(DMSO) may also be employed, although usually at the cost of
greater toxicity.
[0301] The pharmaceutical compositions may, if desired, be
presented in a pack or dispenser device which may contain one or
more unit dosage forms containing the active compound(s). The pack
may, for example, comprise metal or plastic foil, such as a blister
pack. The pack or dispenser device may be accompanied by
instructions for administration.
[0302] 5.8 Effective Dosages
[0303] The active compound(s) or prodrug(s) of the invention, or
compositions thereof, will generally be used in an amount effective
to achieve the intended result, for example in an amount effective
to treat or prevent the particular disease being treated. The
compound(s) may be administered therapeutically to achieve
therapeutic benefit. By therapeutic benefit is meant eradication or
amelioration of the underlying disorder being treated and/or
eradication or amelioration of one or more of the symptoms
associated with the underlying disorder such that the patient
reports an improvement in feeling or condition, notwithstanding
that the patient may still be afflicted with the underlying
disorder. Therapeutic benefit also includes halting or slowing the
progression of the disease, regardless of whether improvement is
realized.
[0304] The amount of compound administered will depend upon a
variety of factors, including, for example, the particular
indication being treated, the mode of administration, the severity
of the indication being treated and the age and weight of the
patient, the bioavailability of the particular active compound,
etc. Determination of an effective dosage is well within the
capabilities of those skilled in the art.
[0305] Effective dosages may be estimated initially from in vitro
assays. For example, an initial dosage for use in animals may be
formulated to achieve a circulating blood or serum concentration of
active compound that is at or above an IC.sub.50 of the particular
compound as measured in an in vitro assay, such as the in vitro
assays described in the Examples section. Calculating dosages to
achieve such circulating blood or serum concentrations taking into
account the bioavailability of the particular compound is well
within the capabilities of skilled artisans. For guidance, the
reader is referred to Fingl & Woodbury, "General Principles,"
In: Goodman and Gilman's The Pharmaceutical Basis of Therapeutics,
Chapter 1, pp. 1-46, latest edition, Pagamonon Press, and the
references cited therein.
[0306] Initial dosages may also be estimated from in vivo data,
such as animal models. Animal models useful for testing the
efficacy of compounds to treat or prevent the various diseases
described above are well-known in the art. Dosage amounts will
typically be in the range of from about 0.0001 or 0.001 or 0.01
mg/kg/day to about 100 mg/kg/day, but may be higher or lower,
depending upon, among other factors, the activity of the compound,
its bioavailability, the mode of administration and various factors
discussed above. Dosage amount and interval may be adjusted
individually to provide plasma levels of the compound(s) which are
sufficient to maintain therapeutic or prophylactic effect. For
example, the compounds may be administered once per week, several
times per week (e.g., every other day), once per day or multiple
times per day, depending upon, among other things, the mode of
administration, the specific indication being treated and the
judgment of the prescribing physician. In cases of local
administration or selective uptake, such as local topical
administration, the effective local concentration of active
compound(s) may not be related to plasma concentration. Skilled
artisans will be able to optimize effective local dosages without
undue experimentation.
[0307] Preferably, the compound(s) will provide therapeutic or
prophylactic benefit without causing substantial toxicity. Toxicity
of the compound(s) may be determined using standard pharmaceutical
procedures. The dose ratio between toxic and therapeutic (or
prophylactic) LD.sub.50/ED.sub.50 effect is the therapeutic index
(LD.sub.50 is the dose lethal to 50% of the population and
ED.sub.50 is the dose therapeutically effective in 50% of the
population). Compounds(s) that exhibit high therapeutic indices are
preferred.
[0308] 5.9 Kits
[0309] The compounds and/or prodrugs described herein may be
assembled in the form of kits. In some embodiments, the kit
provides the compound(s) and reagents to prepare a composition for
administration. The composition may be in a dry or lyophilized
form, or in a solution, particularly a sterile solution. When the
composition is in a dry form, the reagent may comprise a
pharmaceutically acceptable diluent for preparing a liquid
formulation. The kit may contain a device for administration or for
dispensing the compositions, including, but not limited to syringe,
pipette, transdermal patch, or inhalant.
[0310] The kits may include other therapeutic compounds for use in
conjunction with the compounds described herein. In some
embodiments, the therapeutic agents are other anti-cancer and
anti-neoplastic compounds. These compounds may be provided in a
separate form, or mixed with the compounds of the present
invention.
[0311] The kits will include appropriate instructions for
preparation and administration of the composition, side effects of
the compositions, and any other relevant information. The
instructions may be in any suitable format, including, but not
limited to, printed matter, videotape, computer readable disk, or
optical disc.
6. EXAMPLES
[0312] 6.1 In Vitro Cellular Experiments
[0313] The compounds illustrated in TABLES 1-14, supra, were
synthesized using the methods described herein. Salts of the
compounds were prepared using standard techniques.
[0314] The IC.sub.50 values of various compounds against a various
different tumor cell lines were determined using standard in vitro
antiproliferation assays. The tumor cell lines tested were as
follows: A549 (lung); H1299 (lung), ACHN (kidney/p53 wt), CAKI
(renal cell carcinoma), NCI-H460 (lung); HCT116 (colon/p53 wt);
HELA (cervix/p53 wt), HUH7 (liver/p53 wt), HUVEC (primary
endothelial), LNCAP (prostate), HT-29 (colon); MCF-7 (breast);
MCF-7 (breast/ER positive), MDA MB435S (breast); MDA MB231
(breast/ER negative), DU145 (prostate); BxPC-3 (pancreatic); SKOV-3
(ovarian); HepG2 (hepatic), NDHF primary normal human dermal
fibroblast), SKMEL28 (breast/p53mut), SKMEL5 (breast/p53 wt), U2OS
(bone) and PC3 (prostate). The activity of the compounds against
A549 cells and H1299 cells is reported in TABLES 1-14, supra. In
the tables, a "+" indicates an IC.sub.50 of 20 .mu.M or less, a "-"
indicates an IC.sub.50 of >20 .mu.M. A value of "-/+" indicates
that the specific compound exhibited an IC.sub.50 of >20 .mu.M
in a 3-point assay, but exhibited an IC.sub.50 of <20 .mu.M in a
higher-point (e.g., 6-point) assay. A value of "+/-" indicates that
the specific compound exhibited an IC.sub.50 of <20 .mu.M in a
3-point assay, but exhibited an IC.sub.50 of >20 .mu.M in a
higher-point (e.g., 6-point) assay. A blank indicates the specified
compound was not tested against the specified cell line. Many of
the compounds tested exhibited IC50s against A549 and/or H1299
cells in the nanomolar range.

[0316] 6.2 In Vivo Xenograft Experiments
[0317] Compounds 107, 858, 164, 211 and 156 were tested for their
ability to shrink tumors generated from A549 cells in standard
xenograft experiments. Compounds 141 and 211 were tested against
H1299 tumors. When palpable tumors appeared and were of a
preselected volume (approximately 40-150 mm.sup.3), the mice were
administered test compounds as specified in TABLE 16, below.
Preliminary results are reported in TABLE 16.
