BACKGROUND OF THE INVENTION
[0002] 1. Field of the Invention
[0003] This invention relates to novel inhibitors of type I
receptor tyrosine kinases and related kinases, pharmaceutical
compositions containing the inhibitors, and methods for preparing
these inhibitors. The inhibitors are useful for the treatment of
hyperproliferative diseases, such as cancer and inflammation, in
mammals and especially in humans.
[0004] 2. Description of the State of the Art
[0005] The type I receptor tyrosine kinase family consists of four
closely related receptors: EGFR (ErbB1 or HER1), ErbB2 (HER2),
ErbB3 (HER), and ErbB4 (HER4) (Reviewed in Riese and Stern,
Bioessays (1998) 20:41-48; Olayioye et al., EMBO Journal (2000)
19:3159-3167; and Schlessinger, Cell (2002) 110:669-672). These are
single pass transmembrane glycoprotein receptors containing an
extracellular ligand binding region and an intracellular signaling
domain. In addition, all receptors contain an intracellular active
tyrosine kinase domain with the exception of ErbB3, whose kinase
domain does not exhibit enzymatic activity. These receptors
transmit extracellular signals through the cytosol to the nucleus
upon activation. The activation process is initiated by ligand
binding to the extracellular domain of the receptor by one of a
number of different hormones. Upon ligand binding, homo- or
heterodimerization is induced, which results in the activation of
the tyrosine kinase domains and phosphorylation of tyrosines on the
intracellular signaling domains. Since no known ligand for ErbB2
has been described and ErbB3 lacks an active kinase domain, these
receptors must heterodimerize to elicit a response. The
phosphotyrosines then recruit the necessary cofactors to initiate
several different signaling cascades including the ras/raf/MEK/MAPK
and PI3K/AKT pathways. The precise signal elicited will depend on
what ligands are present, since the intracellular signaling domains
differ as to what pathways are activated. These signaling pathways
lead to both cell proliferation and cell survival through
inhibition of apoptosis.
[0006] Several investigators have demonstrated the role of EGFR and
ErbB2 in development of cancer (reviewed in Salomon, et al., Crit.
Rev. Oncol. Hematol. (1995) 19:183-232; Klapper, et al., Adv.
Cancer Res. (2000) 77:25-79; and Hynes and Stern, Biochim. Biophys.
Acta (1994) 1198:165-184). Squamous carcinomas of the head, neck
and lung express high levels of EGFR. Also, constitutively active
EGFR has been found in gliomas, breast cancer and lung cancer.
ErbB2 overexpression occurs in approximately 30% of all breast
cancer. It has also been implicated in other human cancers
including colon, ovary, bladder, stomach, esophagus, lung, uterus
and prostate. ErbB2 overexpression has also been correlated with
poor prognosis in human cancer, including metastasis and early
relapse.
[0007] The type I tyrosine kinase receptor family has been an
active area of anti-cancer research (Reviewed in Mendelsohn and
Baselga, Oncogene (2000) 19:6550-6565; and Normanno et al.,
Endocrine-Related Cancer (2003) 10:1-21). For example, U.S. Pat.
No. 6,828,320 discloses certain substituted quinolines and
quinazolines as protein tyrosine kinase inhibitors.
[0008] Several inhibitors of the EGFR and the ErbB2 signaling
pathway have demonstrated clinical efficacy in cancer treatment.
HERCEPTIN.RTM., a humanized version of anti-ErbB2 monoclonal
antibody, was approved for use in breast cancer in the United
States in 1998. IRESSA.RTM. and TARCEVA.RTM. are small molecule
inhibitors of EGFR that are commercially available. In addition,
several other antibodies and small molecules that target the
interruption of the type I tyrosine kinase receptor signaling
pathways are in clinical and preclinical development. For example,
ERBITUX.RTM., a human-murine chimeric monoclonal antibody against
EGFR, is available for the treatment of irinotecan-refractory
colorectal cancer.

compounds belonging to this subgroup have been found to be highly
potent inhibitors of ErbB2 and are highly selective for ErbB2 over
EGFR. As used herein, the term "highly selective" refers to a
compound wherein the IC.sub.50 for EGFR is at least 20 fold higher
than the IC.sub.50 for ErbB2 as determined by the cellular ErbB2
and EGFR phosphorylation assays described in Examples B and C
Particular compounds of this invention were found to have an
IC.sub.50 for EGFR that is at least 50 fold higher than the
IC.sub.50 for ErbB2. As a further example, particular compounds of
this invention were found to have an IC.sub.50 for EGFR that is at
least 100 fold higher than the IC.sub.50 for ErbB2.
[0179] Accordingly, this invention provides compounds of Formula I
which are highly potent ErbB2 inhibitors and are highly selective
for ErbB2 relative to EGFR. Such compounds would allow treatment of
cancers which can be treated by inhibiting ErbB2, for example
cancers which express or overexpress ErbB2, in a relatively
selective manner, thereby minimizing potential side effects
associated with the inhibition of other kinases such as EGFR.

--NR.sup.15C(.dbd.O)(CH.dbd.CH)R.sup.16a and R.sup.16a represents H
or a substituted or unsubstituted C.sub.2-C.sub.6 alkyl were found
to be inhibitors of both ErbB2 and EGFR. In addition, such
compounds are believed to bind irreversibly to ErbB2 and EGFR.

so specified and defined.
[0261] In addition to compounds of Formula I, the invention also
includes solvates, pharmaceutically acceptable prodrugs, and
pharmaceutically acceptable salts of such compounds.
[0262] The phrase "pharmaceutically acceptable" indicates that the
substance or composition is compatible chemically and/or
toxicologically, with the other ingredients comprising a
formulation, and/or the mammal being treated therewith.
[0263] A "solvate" refers to an association or complex of one or
more solvent molecules and a compound of the invention. Examples of
solvents that form solvates include, but are not limited to, water,
isopropanol, ethanol, methanol, DMSO, ethyl acetate, acetic acid,
and ethanolamine. The term "hydrate" refers to the complex where
the solvent molecule is water.
[0264] A "pharmaceutically acceptable prodrug" is a compound that
may be converted under physiological conditions or by solvolysis to
the specified compound or to a pharmaceutically acceptable salt of
such compound. Prodrugs include compounds wherein an amino acid
residue, or a polypeptide chain of two or more (e.g., two, three or
four) amino acid residues, is covalently joined through an amide or
ester bond to a free amino, hydroxy or carboxylic acid group of a
compound of the present invention. The amino acid residues include
but are not limited to the 20 naturally occurring amino acids
commonly designated by three letter symbols and also includes
phosphoserine, phosphothreonine, phosphotyrosine, 4-hydroxyproline,
hydroxylysine, demosine, isodemosine, gamma-carboxyglutamate,
hippuric acid, octahydroindole-2-carboxylic acid, statine,
1,2,3,4-tetrahydroisoquinoline-3-carboxylic acid, penicillamine,
ornithine, 3-methylhistidine, norvaline, beta-alanine,
gamma-aminobutyric acid, cirtulline, homocysteine, homoserine,
methyl-alanine, para-benzoylphenylalanine, phenylglycine,
propargylglycine, sarcosine, methionine sulfone and
tert-butylglycine. Particular examples of prodrugs of this
invention include compounds of Formula I covalently joined to a
phosphate residue or a valine residue.
[0265] Additional types of prodrugs are also encompassed. For
instance, a free carboxyl group of a compound of Formula I can be
derivatized as an amide or alkyl ester. As another example,
compounds of this invention comprising free hydroxy groups may be
derivatized as prodrugs by converting the hydroxy group into groups
such as, but not limited to, phosphate ester, hemisuccinate,
dimethylaminoacetate, or phosphoryloxymethyloxycarbonyl groups, as
outlined in Advanced Drug Delivery Reviews, 1996, 19, 115.
Carbamate prodrugs of hydroxy and amino groups are also included,
as are carbonate prodrugs, sulfonate esters and sulfate esters of
hydroxy groups. Derivatization of hydroxy groups as (acyloxy)methyl
and (acyloxy)ethyl ethers wherein the acyl group may be an alkyl
ester, optionally substituted with groups including, but not
limited to, ether, amine and carboxylic acid functionalities, or
where the acyl group is an amino acid ester as described above, are
also encompassed. Prodrugs of this type are described in J. Med.
Chem., 1996, 39, 10. More specific examples include replacement of
the hydrogen atom of the alcohol group with a group such as
(C.sub.1-C.sub.6)alkanoyloxymethyl,
1-((C.sub.1-C.sub.6)alkanoyloxy)ethyl,
1-methyl-1-((C.sub.1-C.sub.6)alkanoyloxy)ethyl,
(C.sub.1-C.sub.6)alkoxycarbonyloxymethyl,
N--(C.sub.1-C.sub.6)alkoxycarbonylaminomethyl, succinoyl,
(C.sub.1-C.sub.6)alkanoyl, .alpha.-amino(C.sub.1-C.sub.4)alkanoyl,
arylacyl and .alpha.-aminoacyl, or
.alpha.-aminoacyl-.alpha.-aminoacyl, where each .alpha.-aminoacyl
group is independently selected from the naturally occurring
L-amino acids, P(O)(OH).sub.2,
--P(O)(O(C.sub.1-C.sub.6)alkyl).sub.2 or glycosyl (the radical
resulting from the removal of a hydroxyl group of the hemiacetal
form of a carbohydrate).
[0266] Free amines of compounds of Formula I can also be
derivatized as amides, sulfonamides or phosphonamides. All of these
prodrug moieties may incorporate groups including, but not limited
to, ether, amine and carboxylic acid functionalities. For example,
a prodrug can be formed by the replacement of a hydrogen atom in
the amine group with a group such as R-carbonyl, RO-carbonyl,
NRR'-carbonyl where R and R' are each independently
(C.sub.1-C.sub.10)alkyl, (C.sub.3-C.sub.7)cycloalkyl, benzyl, or
R-carbonyl is a natural .alpha.-aminoacyl or natural
.alpha.-aminoacyl-natural .alpha.-aminoacyl, --C(OH)C(O)OY wherein
Y is H, (C.sub.1-C.sub.6)alkyl or benzyl, --C(OY.sub.0)Y.sub.1
wherein Y.sub.0 is (C.sub.1-C.sub.4) alkyl and Y.sub.1 is
(C.sub.1-C.sub.6)alkyl, carboxy(C.sub.1-C.sub.6)alkyl,
amino(C.sub.1-C.sub.4)alkyl or mono-N- or
di-N,N--(C.sub.1-C.sub.6)alkylaminoalkyl, --C(Y.sub.2)Y.sub.3
wherein Y.sub.2 is H or methyl and Y.sub.3 is mono-N- or
di-N,N--(C.sub.1-C.sub.6)alkylamino, morpholino, piperidin-1-yl or
pyrrolidin-1-yl.

[0268] A "pharmaceutically acceptable salt," unless otherwise
indicated, includes salts that retain the biological effectiveness
of the free acids and bases of the specified compound and that are
not biologically or otherwise undesirable. A compound of the
invention may possess a sufficiently acidic, a sufficiently basic,
or both functional groups, and accordingly react with any of a
number of inorganic or organic bases or acids to form a
pharmaceutically acceptable salt. Examples of pharmaceutically
acceptable salts include those salts prepared by reaction of the
compounds of the present invention with a mineral or organic acid
or an inorganic base, such salts including sulfates, pyrosulfates,
bisulfates, sulfites, bisulfites, phosphates,
monohydrogenphosphates, dihydrogenphosphates, metaphosphates,
pyrophosphates, chlorides, bromides, iodides, acetates,
propionates, decanoates, caprylates, acrylates, formates,
isobutyrates, caproates, heptanoates, propiolates, oxalates,
malonates, succinates, suberates, sebacates, fumarates, maleates,
butyn-1,4-dioates, hexyne-1,6-dioates, benzoates, chlorobenzoates,
methylbenzoates, dinitrobenzoates, hydroxybenzoates,
methoxybenzoates, phthalates, sulfonates, xylenesulfonates,
phenylacetates, phenylpropionates, phenylbutyrates, citrates,
lactates, .gamma.-hydroxybutyrates, glycollates, tartrates,
methanesulfonates, propanesulfonates, naphthalene-1-sulfonates,
naphthalene-2-sulfonates, and mandelates. Since a single compound
of the present invention may include more than one acidic or basic
moiety, the compounds of the present invention may include mono, di
or tri-salts in a single compound.
[0269] If the inventive compound is a base, the desired
pharmaceutically acceptable salt may be prepared by any suitable
method available in the art, for example, treatment of the free
base with an acidic compound, for example an inorganic acid such as
hydrochloric acid, hydrobromic acid, sulfuric acid, nitric acid,
phosphoric acid and the like, or with an organic acid, such as
acetic acid, maleic acid, succinic acid, mandelic acid, fumaric
acid, malonic acid, pyruvic acid, oxalic acid, glycolic acid,
salicylic acid, a pyranosidyl acid such as glucuronic acid or
galacturonic acid, an alpha hydroxy acid such as citric acid or
tartaric acid, an amino acid such as aspartic acid or glutamic
acid, an aromatic acid such as benzoic acid or cinnamic acid, a
sulfonic acid such as p-toluenesulfonic acid or ethanesulfonic
acid, or the like.
[0270] If the inventive compound is an acid, the desired
pharmaceutically acceptable salt may be prepared by any suitable
method, for example, treatment of the free acid with an inorganic
or organic base. Examples of suitable inorganic salts include those
formed with alkali and alkaline earth metals such as lithium,
sodium, potassium, barium and calcium. Examples of suitable organic
base salts include, for example, ammonium, dibenzylammonium,
benzylammonium, 2-hydroxyethylammonium,
bis(2-hydroxyethyl)ammonium, phenylethylbenzylamine,
dibenzylethylenediamine, and the like salts. Other salts of acidic
moieties may include, for example, those salts formed with
procaine, quinine and N-methylglucosamine, plus salts formed with
basic amino acids such as glycine, ornithine, histidine,
phenylglycine, lysine and arginine.
[0271] The compounds of Formula I also include other salts of such
compounds which are not necessarily pharmaceutically acceptable
salts, and which may be useful as intermediates for preparing
and/or purifying compounds of Formula I and/or for separating
enantiomers of compounds of Formula I.
[0272] The present invention also embraces isotopically-labeled
compounds of the present invention which are identical to those
recited herein, but for the fact that one or more atoms are
replaced by an atom having an atomic mass or mass number different
from the atomic mass or mass number usually found in nature. All
isotopes of any particular atom or element as specified is
contemplated within the scope of the compounds of the invention,
and their uses. Exemplary isotopes that can be incorporated into
compounds of the invention include isotopes of hydrogen, carbon,
nitrogen, oxygen, phosphorus, sulfur, fluorine, chlorine and
iodine, such as .sup.2H, .sup.3H, .sup.11C, .sup.13C, .sup.14C,
.sup.13N, .sup.15N, .sup.15O, .sup.17O, .sup.18O, .sup.32P,
.sup.33P, .sup.35S, .sup.18F, .sup.36Cl, .sup.123I and .sup.125I.
Certain isotopically-labeled compounds of the present invention
(e.g., those labeled with .sup.3H and .sup.14C) are useful in
compound and/or substrate tissue distribution assays. Tritiated
(i.e., .sup.3H) and carbon-14 (i.e., .sup.14C) isotopes are useful
for their ease of preparation and detectability. Further,
substitution with heavier isotopes such as deuterium (i.e.,
.sup.2H) may afford certain therapeutic advantages resulting from
greater metabolic stability (e.g., increased in vivo half-life or
reduced dosage requirements) and hence may be preferred in some
circumstances. Positron emitting isotopes such as .sup.15O,
.sup.13N, .sup.11C and .sup.18F are useful for positron emission
tomography (PET) studies to examine substrate receptor occupancy.
Isotopically labeled compounds of the present invention can
generally be prepared by following procedures analogous to those
disclosed in the Schemes and/or in the Examples herein below, by
substituting an isotopically labeled reagent for a non-isotopically
labeled reagent.
[0273] Metabolites of Compounds of Formula I
[0274] Also falling within the scope of this invention are the in
vivo metabolic products of compounds of Formula I described herein.
A "metabolite" is a pharmacologically active product produced
through metabolism in the body of a specified compound or salt
thereof. Such products may result, for example, from the oxidation,
reduction, hydrolysis, amidation, deamidation, esterification,
deesterification, glucoronidation, enzymatic cleavage, and the
like, of the administered compound. Accordingly, the invention
includes metabolites of compounds of Formula I, including compounds
produced by a process comprising contacting a compound of this
invention with a mammal for a period of time sufficient to yield a
metabolic product thereof.
[0275] Metabolite products typically are identified by preparing a
radiolabelled (e.g., .sup.14C or .sup.3H) isotope of a compound of
the invention, administering it parenterally in a detectable dose
(e.g., greater than about 0.5 mg/kg) to an animal such as rat,
mouse, guinea pig, monkey, or to a human, allowing sufficient time
for metabolism to occur (typically about 30 seconds to 30 hours)
and isolating its conversion products from the urine, blood or
other biological samples. These products are easily isolated since
they are labeled (others are isolated by the use of antibodies
capable of binding epitopes surviving in the metabolite). The
metabolite structures are determined in conventional fashion, e.g.,
by MS, LC/MS or NMR analysis. In general, analysis of metabolites
is done in the same way as conventional drug metabolism studies
well known to those skilled in the art. The metabolite products, so
long as they are not otherwise found in vivo, are useful in
diagnostic assays for therapeutic dosing of the compounds of the
invention.
[0276] Synthesis of Compounds of Formula I
[0277] Compounds of Formula I may be synthesized by synthetic
routes that include processes analogous to those well known in the
chemical arts, particularly in light of the description contained
herein. The starting materials are generally available from
commercial sources such as Aldrich Chemicals (Milwaukee, Wis.) or
are readily prepared using methods well known to those skilled in
the art (e.g., prepared by methods generally described in Louis F.
Fieser and Mary Fieser, Reagents for Organic Synthesis, v. 1-19,
Wiley, N.Y. (1967-1999 ed.), or Beilsteins Handbuch der organischen
Chemie, 4, Aufl. ed. Springer-Verlag, Berlin, including supplements
(also available via the Beilstein online database).
[0278] Compounds of Formula I may be prepared singly or as compound
libraries comprising at least 2, for example 5 to 1.000 compounds,
or 10 to 100 compounds. Libraries of compounds of Formula I may be
prepared by a combinatorial `split and mix` approach or by multiple
parallel syntheses using either solution phase or solid phase
chemistry, by procedures known to those skilled in the art. Thus
according to a further aspect of the invention there is provided a
compound library comprising at least 2 compounds, or
pharmaceutically acceptable salts thereof.
[0279] For illustrative purposes, Schemes 1-7 show general method
for preparing the compounds of the present invention as well as key
intermediates. For a more detailed description of the individual
reaction steps, see the Examples section below. Those skilled in
the art will appreciate that other synthetic routes may be used to
synthesize the inventive compounds. Although specific starting
materials and reagents are depicted in the Schemes and discussed
below, other starting materials and reagents can be easily
substituted to provide a variety of derivatives and/or reaction
conditions. In addition, many of the compounds prepared by the
methods described below can be further modified in light of this
disclosure using conventional chemistry well known to those skilled
in the art.
##STR00047##
[0280] Scheme 1 illustrates synthesis of "N-linked" quinazoline
compounds (4) of the present invention wherein A and E are as
defined herein. According to Scheme 1,
4-anilino-6-nitro-quinazoline (3) can be prepared by reacting an
appropriate aniline (2) with a quinazoline (1) substituted in the 4
position with a suitable leaving group, for example a chloride,
under standard coupling conditions. The coupling reaction can be
performed in a variety of solvents, such as tBuOH, IPA or DCE and
may require elevated temperatures and may require a mild base, such
as EtN(iPr).sub.2. In one example, the reaction is achieved in a
mixture of IPA and DCE heated to 80.degree. C. Reduction of the
nitro group of compound (3) can be accomplished by a variety of
standard reduction protocols known in the art, such as Pd/C and
H.sub.2, Pd/C and hydrazine, Pt/C with NaOH and H.sub.2, Zn/AcOH,
Zn/NH.sub.4Cl or Fe/HOAc. In one example, the reduction is
accomplished with Pd/C and H.sub.2. When R.sup.2 is a halogen, the
reduction can be accomplished Pt/C with NaOH and H.sub.2 or
Zn/NH.sub.4Cl. The resulting aniline can be coupled with halides,
or reacted with other suitable electrophiles such as aldehydes,
acid chlorides, etc. to provide compound (4). These reactions may
require a suitable base and/or elevated temperatures.
##STR00048##
[0281] Scheme 2 illustrates an alternative route towards "N-linked"
quinazoline compounds (4) wherein A and E are as defined herein.
According to Scheme 2, 4-chloro-6-iodoquinazoline (5) can be used
in place of 4-chloro-6-nitroquinazoline (1) in Scheme 1 to prepare
4-anilino-6-iodoquinazoline (6). The palladium mediated
cross-coupling reaction of the resulting iodoquinazoline (6) with a
suitable amine R.sup.15NH.sub.2 to give compound 4 can be
accomplished by treatment with a palladium catalyst, for example
Pd(OAc).sub.2, Pd(PPh.sub.3).sub.4, PdCl.sub.2(dppf).sub.2,
Pd.sub.2(dba).sub.3, a phosphine ligand and a base in a suitable
organic solvent such as THF, DME or toluene. In one example, the
coupling reaction is accomplished using Pd.sub.2(dba).sub.3, X-PHOS
and Cs.sub.2CO.sub.3 in THF and heating to 65.degree. C. Scheme 2
also demonstrates the preparation of C-linked compounds (7). These
analogs can be prepared from compound (6) by palladium mediated
cross-coupling reactions with boronic acids or organo tin compounds
using standard Suzuki or Stille reaction conditions well known in
the art.
##STR00049##
[0282] Scheme 3 illustrates a route towards "N-linked"
oxazoline-quinazoline compounds wherein A and E are as defined
herein. According to Scheme 3, amidine (8) can be condensed with
suitable aniline (2) in the presence of an acid such as HOAc in a
suitable organic solvent such as isopropyl acetate (IPAc) to
provide the thiourea (9). The oxazoline (10) can be prepared by
cyclizing the thiourea (9) under a variety of conditions, for
example, by treating the thiourea (9) with TsCI and aqueous NaOH in
THF.
##STR00050##
[0283] Scheme 4 illustrates the synthesis of an ether linked
quinazoline (13) of the present invention wherein A and E are as
defined herein. According to Scheme 4, 4-chloro-6-oxy-quinazoline
(11) can be reacted with suitable aniline (2) under standard
coupling conditions as described in Scheme 1 to provide compound
(12). The oxygen moiety of compound (11) can be substituted with
various R.sup.a groups, wherein R.sup.a is H, R.sup.15 or a
suitable alcohol protecting group, such as an acyl group. After
reaction with the aniline, the optional protection group can be
removed under suitable conditions, such as ammonia in MeOH in case
of an acetate protecting group. The hydroxyl group of compound (12)
can be coupled with a suitable alkyl halide R.sup.15-X and an
appropriate base, such as K.sub.2CO.sub.3, Cs.sub.2CO.sub.3 or
Cs(OH).sub.2 in an organic solvent such as DMF or acetone to
provide compound 13. In one example, the alkylation is achieved
with R.sup.15--Br using Cs.sub.2CO.sub.3 as a base in DMF.
Alternatively, R.sup.15--OH can be used in place of R.sup.15--X if
the alcohol has been converted to an activated leaving group, such
as a tosylate. In yet another method, the hydroxyl group of 12 can
be coupled with an alcohol R.sup.15--OH under standard Mitsunobu
conditions, such as DIAD/PPh.sub.3 in THF, to provide compound
13.
##STR00051##
[0284] Scheme 5 illustrates a method of preparing aniline
intermediates (2a) and (2b) suitable for use in Schemes 1-4, from
phenols (14) and (15), respectively. Phenols (14) and (15) are
commercially available or known in the literature, or can be
prepared by those skilled in the art by standard procedures. Phenol
(14) can be reacted with an optionally substituted
4-fluoronitrobenzene (16) and a suitable base, for example
K.sub.2CO.sub.3, NaH, or Cs.sub.2CO.sub.3 in a polar organic
solvent such as DMF at elevated temperatures to provide the coupled
product (17). In one example, phenol (14) is reacted with an
optionally substituted 4-fluoronitrobenzene (16) in the presence of
Cs.sub.2CO.sub.3 in DMF at 80.degree. C. The nitro group of
compound (17) can be reduced to the desired aniline compound (2a)
using standard reduction methods such as Pd/C and H.sub.2, Pd/C and
hydrazine, Pt/C with NaOH and H.sub.2, Zn/AcOH, Zn/NH.sub.4Cl or
Fe/HOAc. In one example, the reduction is accomplished with Pd/C
and H.sub.2 (40 psi). When R.sub.2 is a halogen, the reduction can
be accomplished using Pt/C with NaOH and H.sub.2 or Zn/NH.sub.4Cl.
In a similar manner, compound (2b) can be prepared from phenol
(15).
##STR00052##
[0285] Scheme 6 illustrates a method of preparing phenol
intermediate (14a) suitable for use in Scheme 5. Chloro-pyridine
(18) can be reacted with hydrazine, for example in pyridine at
80.degree. C. The resulting compound can then be reacted with a
carboxylic acid equivalent, such as triethyl orthoformate or
trimethoxy methane and acid, such as HCl, HOAc or
4-methylbenzenesulfonic acid. In one example, the cyclization is
achieved with trimethoxy methane and 4-methylbenzenesulfonic acid
to furnish the triazole. The benzyl group can be removed under
standard conditions, for example, Pd/C and H.sub.2, to give
(14a).
##STR00053##
[0286] Scheme 7 illustrates a method of preparing phenol
intermediate (14b) suitable for use in Scheme 5. A suitably
substituted acetal can reacted with DMF and POCl.sub.3 to provide a
dimethylamino-acrylaldehyde intermediate. Conversion of this
intermediate to a pyrazolo-pyrimidine can be accomplished by
treatment with an optionally substituted 1H-pyrazol-3-amine in base
at elevated temperatures, for example NaOMe in MeOH at 60.degree.
C. The benzyl group can be removed to give (14b) under standard
conditions, such as Pd/C and H.sub.2.
##STR00054##
[0287] Scheme 8 illustrates the preparation of aniline
intermediates (2c) and (2d) suitable for use in Schemes 1-4.
According to Scheme 8, the palladium mediated cross-coupling
reaction of 2-chloro-4-benzyloxy-pyridine (18) with a suitable
amine to give compound (19) can be accomplished by treatment with a
palladium catalyst, for example Pd(OAc).sub.2, Pd(PPh.sub.3).sub.4,
PdCl.sub.2(dppf).sub.2, Pd.sub.2(dba).sub.3, a phosphine ligand and
a base in a suitable organic solvent such as THF, DME or toluene.
In one example, the coupling is accomplished using LHMDS with
Pd.sub.2(dba).sub.3, X-PHOS and Cs.sub.2CO.sub.3 in THF and heating
to 65.degree. C. The resulting 2-aminopyridine can be optionally
protected as the Boc-carbamate under standard conditions, for
example Boc.sub.2O in tBuOH. The benzyl group of compound (19) can
be removed under standard conditions, such as Pd/C and H.sub.2. The
resulting phenol is then reacted with an optionally substituted
4-fluoro-nitrobenzene (16) as described in Scheme 5 to provide the
coupled product (20). The Boc group of compound (20) can be removed
with acid, for example TFA in DCM. The deprotected 2-aminopyridine
(21) can be converted to an imidazopyridine derivative by reaction
with a suitably substituted 2-halo-carbonyl compound. For example,
compound (21) can be reacted with either chloroacetaldehyde,
chloroacetone, or 2-chloropropanal in THF heated to reflux.
Conversion of compound (21) into triazolopyridines can be achieved
by two-step procedure that includes condensation of (21) with
dimethylforamide dimethylacetal to provide a
N,N-dimethyl-formimidamide derivative, which is then reacted with
hydroxylamine sulfonic acid to provide the triazolopyridine.
Reduction of the corresponding nitro group can be accomplished as
described in Scheme 5 to provide compounds (2c) and (2d).
##STR00055##
[0288] Scheme 9 illustrates an alternative synthesis of
intermediate aniline compound (2e) and (2f) suitable for use in
Schemes 1-4. According to Scheme 9, 2-chloro-5-hydroxypyridine is
reacted with an optionally substituted 4-fluoronitrobenzene (16) as
described in Scheme 5. The chloro derivative (22) can be converted
to the amino derivative (23) under palladium mediated cross
coupling conditions as described in Scheme 8. Conversion of
compound (23) to provide imidazopyridines or triazolopyridines can
be accomplished under suitable conditions as described in Scheme 8.
Reduction of the corresponding nitro groups can be accomplished as
described in Scheme 5 to provide compounds (2e) and (2f).
##STR00056##
[0289] Scheme 10 illustrates an alternative synthesis of
intermediate aniline compound (2g) suitable for use in Schemes 1-4.
According to Scheme 10, phenol substituted benzofused-heterocycles
(14) and (25) can be reacted with dimethyl thiocarbamoyl chloride
and a base, for example, NaH in THF, with heating to reflux.
Rearrangement of the resulting thiocarbonyl carbamate is
accomplished by heating to elevated temperatures, for example
200.degree. C., in diphenyl ether. The product is then hydrolyzed
under basic conditions, such as KOH in MeOH heated to reflux. The
thiol (24) can then be reacted with an optionally substituted
4-fluoronitrobenzene (16) as described in Scheme 5. Reduction of
the nitro group can be accomplished as described in Scheme 5, for
example with Fe/HOAc or Zn/NH.sub.4Cl, to provide compound (2g). An
alternative synthesis of aniline (2g) includes reacting a
halo-substituted fused heterocyclic compound (25), where X=Br, with
(iPr).sub.3SiSH and a palladium catalyst, for example
Pd(PPh.sub.3).sub.4 in THF, and heating to reflux. The resulting
protected thiol (26) can be de-silated and reacted with an
optionally substituted 4-fluoronitrobenzene (16) in situ with a
fluoride source, such as CsF in DMF. Reduction of the nitro group
to yield (2 g) is accomplished under standard reaction
conditions.
##STR00057##
[0290] Scheme 11 illustrates a method of preparing aniline (2h)
suitable for use in Schemes 1-4. According to Scheme 11, acid
chloride (27) is reacted with 2-pyridone and a base to yield ester
(28), for example with Et.sub.3N in DCM. Boronic acid (29) is
prepared from the halo substituted fused heterocycle (25) by
standard conditions, for example by treatment with nBuLi at low
temperatures followed by B(OMe).sub.3. Compound (28) is then
coupled with boronic acid (29) under palladium mediated
cross-coupling conditions, for example Pd(OAc).sub.2, PPh.sub.3 and
dioxane, and heating to 50.degree. C. (Tatamidani, H.; Kakiuchi,
F.; Chatani, N. Org. Lett. 2004, 6, 3597). The resulting nitro
compound can be reduced under standard conditions as described in
Scheme 5, such as Fe/HOAc or Zn/NH.sub.4Cl, to provide compound
(2h).

[0317] wherein R.sup.1, R.sup.2, A, E and n are as defined for
Formula I. Compounds of Formula (F1) are useful for preparing
pharmaceutical compounds such as the ErbB inhibitors of Formula
I.
[0318] In preparing compounds of Formula I, protection of remote
functionalities (e.g., primary or secondary amines, alcohols, etc.)
of intermediates may be necessary. The need for such protection
will vary depending on the nature of the remote functionality and
the conditions of the preparation methods. Suitable
amino-protecting groups (NH-Pg) include acetyl, trifluoroacetyl,
t-butoxycarbonyl (BOC), benzyloxycarbonyl (CBz) and
9-fluorenylmethyleneoxycarbonyl (Fmoc). The need for such
protection is readily determined by one skilled in the art. For a
general description of protecting groups and their use, see T. W.
Greene, Protective Groups in Organic Synthesis, John Wiley &
Sons, New York, 1991.
[0319] Methods of Separation
[0320] In any of the synthetic methods for preparing compounds of
Formula I, it may be advantageous to separate reaction products
from one another and/or from starting materials. The desired
products of each step or series of steps is separated and/or
purified to the desired degree of homogeneity by the techniques
common in the art. Such separations involve, for example,
multiphase extraction, crystallization from a solvent or solvent
mixture, distillation, sublimation, or chromatography.
Chromatography can involve any number of methods including, for
example: reverse-phase and normal phase; size exclusion; ion
exchange; high, medium and low pressure liquid chromatography
methods and apparatus; small scale analytical; simulated moving bed
(SMB) and preparative thin or thick layer chromatography, as well
as techniques of small scale thin layer and flash
chromatography.
[0321] Another class of separation methods involves treatment of a
reaction mixture with a reagent selected to bind to or render
otherwise separable a desired product, unreacted starting material,
reaction by-product, or the like. Such reagents include adsorbents
such as activated carbon, molecular sieves, ion exchange media, or
the like. Alternatively, the reagents can be acids in the case of a
basic material, bases in the case of an acidic material, binding
reagents such as antibodies, binding proteins, selective chelators
such as crown ethers, liquid/liquid ion extraction reagents (LIX),
or the like.
[0322] Selection of appropriate method(s) of separation depends on
the nature of the materials involved. For example, boiling point
and molecular weight in distillation and sublimation, presence or
absence of polar functional groups in chromatography, stability of
materials in acidic and basic media in multiphase extraction, and
the like. One skilled in the art will apply techniques most likely
to achieve the desired separation.
[0323] Diastereomeric mixtures can be separated into their
individual diastereomers on the basis of their physical chemical
differences by methods well known to those skilled in the art, such
as by chromatography and/or fractional crystallization. Enantiomers
can be separated by converting the enantiomeric mixture into a
diastereomeric mixture by reaction with an appropriate optically
active compound (e.g., chiral auxiliary such as a chiral alcohol or
Mosher's acid chloride), separating the diastereomers and
converting (e.g., hydrolyzing) the individual diastereoisomers to
the corresponding pure enantiomers. Also, some of the compounds of
the present invention may be atropisomers (e.g., substituted
biaryls) and are considered as part of this invention. Enantiomers
can also be separated by use of a chiral HPLC column.
[0324] A single stereoisomer, e.g., an enantiomer, substantially
free of its stereoisomer may be obtained by resolution of the
racemic mixture using a method such as formation of diastereomers
using optically active resolving agents (Eliel, E. and Wilen, S.
"Stereochemistry of Organic Compounds," John Wiley & Sons,
Inc., New York, 1994; Lochmuller, C. H., J. Chromatogr., (1975)
113(3):283-302). Racemic mixtures of chiral compounds of the
invention can be separated and isolated by any suitable method,
including: (1) formation of ionic, diastereomeric salts with chiral
compounds and separation by fractional crystallization or other
methods, (2) formation of diastereomeric compounds with chiral
derivatizing reagents, separation of the diastereomers, and
conversion to the pure stereoisomers, and (3) separation of the
substantially pure or enriched stereoisomers directly under chiral
conditions. See: "Drug Stereochemistry, Analytical Methods and
Pharmacology," Irving W. Wainer, Ed., Marcel Dekker, Inc., New York
(1993).
[0325] Under method (1), diastereomeric salts can be formed by
reaction of enantiomerically pure chiral bases such as brucine,
quinine, ephedrine, strychnine,
.alpha.-methyl-.beta.-phenylethylamine (amphetamine), and the like
with asymmetric compounds bearing acidic functionality, such as
carboxylic acid and sulfonic acid. The diastereomeric salts may be
induced to separate by fractional crystallization or ionic
chromatography. For separation of the optical isomers of amino
compounds, addition of chiral carboxylic or sulfonic acids, such as
camphorsulfonic acid, tartaric acid, mandelic acid, or lactic acid
can result in formation of the diastereomeric salts.
[0326] Alternatively, by method (2), the substrate to be resolved
is reacted with one enantiomer of a chiral compound to form a
diastereomeric pair (E. and Wilen, S. "Stereochemistry of Organic
Compounds", John Wiley & Sons, Inc., 1994, p. 322).
Diastereomeric compounds can be formed by reacting asymmetric
compounds with enantiomerically pure chiral derivatizing reagents,
such as menthyl derivatives, followed by separation of the
diastereomers and hydrolysis to yield the pure or enriched
enantiomer. A method of determining optical purity involves making
chiral esters, such as a menthyl ester, e.g., (-)menthyl
chloroformate in the presence of base, or Mosher ester,
.alpha.-methoxy-.alpha.-(trifluoromethyl)phenyl acetate (Jacob III.
J. Org. Chem., (1982) 47:4165), of the racemic mixture, and
analyzing the .sup.1H NMR spectrum for the presence of the two
atropisomeric enantiomers or diastereomers. Stable diastereomers of
atropisomeric compounds can be separated and isolated by normal-
and reverse-phase chromatography following methods for separation
of atropisomeric naphthyl-isoquinolines (WO 96/15111). By method
(3), a racemic mixture of two enantiomers can be separated by
chromatography using a chiral stationary phase ("Chiral Liquid
Chromatography" (1989) W. J. Lough, Ed., Chapman and Hall, New
York; Okamoto, J. of Chromatogr., (1990) 513:375-378). Enriched or
purified enantiomers can be distinguished by methods used to
distinguish other chiral molecules with asymmetric carbon atoms,
such as optical rotation and circular dichroism.
[0327] Methods of Treatment with Compounds of Formula I
[0328] The compounds of the present invention can be used as
prophylactics or therapeutic agents for treating diseases mediated
by modulation or regulation of type I receptor tyrosine kinases
and/or serine, threonine, and/or dual specificity kinases. An
"effective amount" is intended to mean that amount of compound
that, when administered to a mammal in need of such treatment, is
sufficient to effect treatment for a disease mediated by the
activity of one or more type I receptor tyrosine kinases and/or
serine, threonine, and/or dual specificity kinases. Thus, for
example, a therapeutically effective amount of a compound selected
from Formula I or a solvate, metabolite, or pharmaceutically
acceptable salt or prodrug thereof, is a quantity sufficient to
modulate, regulate, or inhibit the activity of one or more type I
receptor tyrosine kinases and/or serine, threonine, and/or dual
specificity kinases such that a disease condition which is mediated
by that activity is reduced or alleviated.
[0329] The terms "treat" or "treatment" refer to both therapeutic
treatment and prophylactic or preventative measures, wherein the
object is to prevent or slow down (lessen) an undesired
physiological change or disorder. For purposes of this invention,
beneficial or desired clinical results include, but are not limited
to, alleviation of symptoms, diminishment of extent of disease,
stabilized (i.e., not worsening) state of disease, delay or slowing
of disease progression, amelioration or palliation of the disease
state, and remission (whether partial or total), whether detectable
or undetectable. "Treatment" can also mean prolonging survival as
compared to expected survival if not receiving treatment. Those in
need of treatment include those already with the condition or
disorder as well as those prone to have the condition or disorder
or those in which the condition or disorder is to be prevented. The
terms "treating," "treat," and "treatment" embrace both
preventative, i.e., prophylactic, and palliative treatment.
[0330] The compounds of the present invention possess
anti-cell-proliferation properties, which are believed to arise
from their Class I receptor tyrosine kinase inhibitory activity.
Accordingly the compounds of the present invention are expected to
be useful in the treatment of diseases or medical conditions
mediated alone or in part by Class I receptor tyrosine kinase
enzymes, i.e. the compounds may be used to produce a Class I
receptor tyrosine kinase inhibitory effect in a warm-blooded animal
in need of such treatment. Thus the compounds of the present
invention provide a method for treating the proliferation of
malignant cells characterized by inhibition of Class I receptor
tyrosine kinase enzymes, i.e., the compounds may be used to produce
an anti-proliferative effect mediated alone or in part by the
inhibition of Class I receptor tyrosine kinase. Accordingly, the
compounds of the present invention are expected to be useful in the
treatment of cancer by providing an anti-proliferative effect,
particularly in the treatment of Class I receptor tyrosine kinase
sensitive cancers such as cancers of the breast, lung, colon,
rectum, stomach, prostate, bladder, pancreas and ovary. The
compounds of the present invention are also expected to be useful
in the treatment of other cell-proliferation diseases such as
psoriasis.
[0331] Accordingly, one aspect of this invention relates to a
pharmaceutical composition for the treatment of a
hyperproliferative disorder or an abnormal cell growth in a mammal,
which comprises a therapeutically effective amount of a compound of
the present invention, or a solvate, metabolite, or
pharmaceutically acceptable salt or prodrug thereof, and a
pharmaceutically acceptable carrier.
[0332] The terms "abnormal cell growth" and "hyperproliferative
disorder" are used interchangeably in this application.
[0333] "Abnormal cell growth," as used herein, unless otherwise
indicated, refers to cell growth that is independent of normal
regulatory mechanisms (e.g., loss of contact inhibition). This
includes, for example, the abnormal growth of: (1) tumor cells
(tumors) that proliferate by expressing a mutated tyrosine kinase
or over-expression of a receptor tyrosine kinase; (2) benign and
malignant cells of other proliferative diseases in which aberrant
tyrosine kinase activation occurs; (3) any tumors that proliferate
by receptor tyrosine kinases; (4) any tumors that proliferate by
aberrant serine/threonine kinase activation; and (5) benign and
malignant cells of other proliferative diseases in which aberrant
serine/theroine kinase activation occurs.

[0345] Combination Therapy
[0346] The compounds of the present invention can be used in
combination with one or more additional drugs such as described
below. The dose of the second drug can be appropriately selected
based on a clinically employed dose. The proportion of the compound
of the present invention and the second drug can be appropriately

[0359] In one embodiment the second compound of the pharmaceutical
combination formulation or dosing regimen has complementary
activities to the compound of Formula I such that they do not
adversely affect each other. Such drugs are suitably present in
combination in amounts that are effective for the purpose intended.
Accordingly, another aspect of the present invention provides a
composition comprising a compound of Formula I, or a solvate,
metabolite, or pharmaceutically acceptable salt or prodrug thereof,
in combination with a second drug, such as described herein.
[0360] The compound(s) of Formula I and the additional
pharmaceutically active agent(s) may be administered together in a
unitary pharmaceutical composition or separately and, when
administered separately this may occur simultaneously or
sequentially in any order. Such sequential administration may be
close in time or remote in time. The amounts of the compound(s) of
Formula I and the second agent(s) and the relative timings of
administration will be selected in order to achieve the desired
combined therapeutic effect.
[0361] Suitable dosages for any of the above coadministered agents
are those presently used and may be lowered due to the combined
action (synergy) of the newly identified agent and other
chemotherapeutic agents or treatments.
[0362] The combination therapy may provide "synergy" and prove
"synergistic", i.e., the effect achieved when the active
ingredients used together is greater than the sum of the effects
that results from using the compounds separately. A synergistic
effect may be attained when the active ingredients are: (1)
co-formulated and administered or delivered simultaneously in a
combined, unit dosage formulation; (2) delivered by alternation or
in parallel as separate formulations; or (3) by some other regimen.
When delivered in alternation therapy, a synergistic effect may be
attained when the compounds are administered or delivered
sequentially, e.g., by different injections in separate syringes.
In general, during alternation therapy, an effective dosage of each
active ingredient is administered sequentially, i.e., serially,
whereas in combination therapy, effective dosages of two or more
active ingredients are administered together.
[0363] The compounds of the present invention can be used, for
example in combination with additional drug(s) such as a
therapeutic agent for
[0364] Administration of Compounds of Formula I
[0365] The compounds of the invention may be administered by any
route appropriate to the condition to be treated. Suitable routes
include oral, parenteral (including subcutaneous, intramuscular,
intravenous, intraarterial, intradermal, intrathecal and epidural),
transdermal, rectal, nasal, topical (including buccal and
sublingual), vaginal, intraperitoneal, intrapulmonary and
intranasal. It will be appreciated that the preferred route may
vary with for example the condition of the recipient. Where the
compound is administered orally, it may be formulated as a pill,
capsule, tablet, etc. with a pharmaceutically acceptable carrier or
excipient. Where the compound is administered parenterally, it may
be formulated with a pharmaceutically acceptable parenteral vehicle
and in a unit dosage injectable form, as detailed below.
[0366] Pharmaceutical Formulations
[0367] In order to use a compound of Formula I or a
pharmaceutically acceptable salt, solvate, metabolite or prodrug
thereof for the therapeutic treatment (including prophylactic
treatment) of mammals including humans, it is normally formulated
in accordance with standard pharmaceutical practice as a
pharmaceutical composition. According to this aspect of the
invention there is provided a pharmaceutical composition that
comprises a compound of the Formula I, or a pharmaceutically
acceptable salt, solvate, metabolite or prodrug thereof, in
association with a pharmaceutically acceptable diluent or
carrier.
[0368] The pharmaceutical compositions of the invention are
formulated, dosed and administered in a fashion, i.e., amounts,
concentrations, schedules, course, vehicles and route of
administration, consistent with good medical practice. Factors for
consideration in this context include the particular disorder being
treated, the particular mammal being treated, the clinical
condition of the individual patient, the cause of the disorder, the
site of delivery of the agent, the method of administration, the
scheduling of administration, and other factors known to medical
practitioners. The therapeutically effective amount of the compound
to be administered will be governed by such considerations, and is
the minimum amount necessary to prevent, ameliorate, or treat the
disorder. The compound of the present invention is typically
formulated into pharmaceutical dosage forms to provide an easily
controllable dosage of the drug and to enable patient compliance
with the prescribed regimen.
[0369] The composition for use herein is preferably sterile. In
particular, formulations to be used for in vivo administration must
be sterile. Such sterilization is readily accomplished, for
example, by filtration through sterile filtration membranes. The
compound ordinarily can be stored as a solid composition, a
lyophilized formulation or as an aqueous solution.
[0370] Pharmaceutical formulations of the compounds of the present
invention may be prepared for various routes and types of
administration. For example, a compound of Formula I having the
desired degree of purity may optionally be mixed with
pharmaceutically acceptable diluents, carriers, excipients or
stabilizers (Remington's Pharmaceutical Sciences (1980) 16th
edition, Osol, A. Ed.), in the form of a lyophilized formulation, a
milled powder, or an aqueous solution. Formulation may be conducted
by mixing at ambient temperature at the appropriate pH, and at the
desired degree of purity, with physiologically acceptable carriers,
i.e., carriers that are non-toxic to recipients at the dosages and
concentrations employed. The pH of the formulation depends mainly
on the particular use and the concentration of compound, but may
range from about 3 to about 8. Formulation in an acetate buffer at
pH 5 is a suitable embodiment. The formulations may be prepared
using conventional dissolution and mixing procedures. For example,
the bulk drug substance (i.e., compound of the present invention or
stabilized form of the compound (e.g., complex with a cyclodextrin
derivative or other known complexation agent) is dissolved in a
suitable solvent in the presence of one or more excipients.
[0371] The particular carrier, diluent or excipient used will
depend upon the means and purpose for which the compound of the
present invention is being applied. Solvents are generally selected
based on solvents recognized by persons skilled in the art as safe
(GRAS) to be administered to a mammal. In general, safe solvents
are non-toxic aqueous solvents such as water and other non-toxic
solvents that are soluble or miscible in water. Suitable aqueous
solvents include water, ethanol, propylene glycol, polyethylene
glycols (e.g., PEG 400, PEG 300), etc. and mixtures thereof.
Acceptable diluents, carriers, excipients and stabilizers are
nontoxic to recipients at the dosages and concentrations employed,
and include buffers such as phosphate, citrate and other organic
acids; antioxidants including ascorbic acid and methionine;
preservatives (such as octadecyldimethylbenzyl ammonium chloride;
hexamethonium chloride; benzalkonium chloride, benzethonium
chloride; phenol, butyl or benzyl alcohol; alkyl parabens such as
methyl or propyl paraben; catechol; resorcinol; cyclohexanol;
3-pentanol; and m-cresol); low molecular weight (less than about 10
residues) polypeptides; proteins, such as serum albumin, gelatin,
or immunoglobulins; hydrophilic polymers such as
polyvinylpyrrolidone; amino acids such as glycine, glutamine,
asparagine, histidine, arginine, or lysine; monosaccharides,
disaccharides and other carbohydrates including glucose, mannose,
or dextrins; chelating agents such as EDTA; sugars such as sucrose,
mannitol, trehalose or sorbitol; salt-forming counter-ions such as
sodium; metal complexes (e.g., Zn-protein complexes); and/or
non-ionic surfactants such as TWEEN.TM., PLURONICS.TM. or
polyethylene glycol (PEG). The formulations may also include one or
more stabilizing agents, surfactants, wetting agents, lubricating
agents, emulsifiers, suspending agents, preservatives,
antioxidants, opaquing agents, glidants, processing aids,
colorants, sweeteners, perfuming agents, flavoring agents and other
known additives to provide an elegant presentation of the drug
(i.e., a compound of the present invention or pharmaceutical
composition thereof) or aid in the manufacturing of the
pharmaceutical product (i.e., medicament). The active
pharmaceutical ingredients may also be entrapped in microcapsules
prepared, for example, by coacervation techniques or by interfacial
polymerization, for example, hydroxymethylcellulose or
gelatin-microcapsules and poly-(methylmethacylate) microcapsules,
respectively, in colloidal drug delivery systems (for example,
liposomes, albumin microspheres, microemulsions, nano-particles and
nanocapsules) or in macroemulsions. Such techniques are disclosed
in Remington's Pharmaceutical Sciences 16th edition, Osol, A. Ed.
(1980). A "liposome" is a small vesicle composed of various types
of lipids, phospholipids and/or surfactant which is useful for
delivery of a drug (such as the compounds disclosed herein and,
optionally, a chemotherapeutic agent) to a mammal. The components
of the liposome are commonly arranged in a bilayer formation,
similar to the lipid arrangement of biological membranes.
[0372] Sustained-release preparations of compounds of Formula I may
be prepared. Suitable examples of sustained-release preparations
include semipermeable matrices of solid hydrophobic polymers
containing a compound of Formula I, which matrices are in the form
of shaped articles, e.g., films, or microcapsules. Examples of
sustained-release matrices include polyesters, hydrogels (for
example, poly(2-hydroxyethyl-methacrylate), or poly(vinylalcohol)),
polylactides (U.S. Pat. No. 3,773,919), copolymers of L-glutamic
acid and gamma-ethyl-L-glutamate, non-degradable ethylene-vinyl
acetate, degradable lactic acid-glycolic acid copolymers such as
the LUPRON DEPOT.TM. (injectable microspheres composed of lactic
acid-glycolic acid copolymer and leuprolide acetate) and
poly-D-(-)-3-hydroxybutyric acid.
[0373] The pharmaceutical compositions of compounds of Formula I
may be in the form of a sterile injectable preparation, such as a
sterile injectable aqueous or oleaginous suspension. This
suspension may be formulated according to the known art using those
suitable dispersing or wetting agents and suspending agents which
have been mentioned above. The sterile injectable preparation may
also be a sterile injectable solution or suspension in a non-toxic
parenterally acceptable diluent or solvent, such as a solution in
1,3-butanediol or prepared as a lyophilized powder. Among the
acceptable vehicles and solvents that may be employed are water,
Ringer's solution and isotonic sodium chloride solution. In
addition, sterile fixed oils may conventionally be employed as a
solvent or suspending medium. For this purpose any bland fixed oil
may be employed including synthetic mono- or diglycerides. In
addition, fatty acids such as oleic acid may likewise be used in
the preparation of injectables.
[0374] Formulations suitable for parenteral administration include
aqueous and non-aqueous sterile injection solutions which may
contain anti-oxidants, buffers, bacteriostats and solutes which
render the formulation isotonic with the blood of the intended
recipient; and aqueous and non-aqueous sterile suspensions which
may include suspending agents and thickening agents.
[0375] The compositions of the invention may also be in a form
suitable for oral use (for example as tablets, lozenges, hard or
soft capsules, aqueous or oily suspensions, emulsions, dispersible
powders or granules, syrups or elixirs), for topical use (for
example as creams, ointments, gels, or aqueous or oily solutions or
suspensions), for administration by inhalation (for example as a
finely divided powder or a liquid aerosol), for administration by
insufflation (for example as a finely divided powder)
[0376] Suitable pharmaceutically-acceptable excipients for a tablet
formulation include, for example, inert diluents such as lactose,
sodium carbonate, calcium phosphate or calcium carbonate,
granulating and disintegrating agents such as corn starch or
algenic acid; binding agents such as starch; lubricating agents
such as magnesium stearate, stearic acid or talc; preservative
agents such as ethyl or propyl p-hydroxybenzoate, and
anti-oxidants, such as ascorbic acid. Tablet formulations may be
uncoated or coated either to modify their disintegration and the
subsequent absorption of the active ingredient within the
gastrointestinal tract, or to improve their stability and/or
appearance, in either case using conventional coating agents and
procedures well known in the art.
[0377] Compositions for oral use may be in the form of hard gelatin
capsules in which the active ingredient is mixed with an inert
solid diluent, for example, calcium carbonate, calcium phosphate or
kaolin, or as soft gelatin capsules in which the active ingredient
is mixed with water or an oil such as peanut oil, liquid paraffin,
or olive oil.
[0378] Aqueous suspensions generally contain the active ingredient
in finely powdered form together with one or more suspending
agents, such as sodium carboxymethylcellulose, methylcellulose,
hydroxypropylmethylcellulose, sodium alginate,
polyvinyl-pyrrolidone, gum tragacanth and gum acacia; dispersing or
wetting agents such as lecithin or condensation products of an
alkylene oxide with fatty acids (for example polyoxethylene
stearate), or condensation products of ethylene oxide with long
chain aliphatic alcohols, for example heptadecaethyleneoxycetanol,
or condensation products of ethylene oxide with partial esters
derived from fatty acids and a hexitol such as polyoxyethylene
sorbitol monooleate, or condensation products of ethylene oxide
with partial esters derived from fatty acids and hexitol
anhydrides, for example polyethylene sorbitan monooleate. The
aqueous suspensions may also contain one or more preservatives
(such as ethyl or propyl p-hydroxybenzoate, anti-oxidants (such as
ascorbic acid), coloring agents, flavoring agents, and/or
sweetening agents (such as sucrose, saccharine or aspartame).
[0379] Oily suspensions may be formulated by suspending the active
ingredient in a vegetable oil (such as arachis oil, olive oil,
sesame oil or coconut oil) or in a mineral oil (such as liquid
paraffin). The oily suspensions may also contain a thickening agent
such as beeswax, hard paraffin or cetyl alcohol. Sweetening agents
such as those set out above, and flavoring agents may be added to
provide a palatable oral preparation. These compositions may be
preserved by the addition of an anti-oxidant such as ascorbic
acid.
[0380] Dispersible powders and granules suitable for preparation of
an aqueous suspension by the addition of water generally contain
the active ingredient together with a dispersing or wetting agent,
suspending agent and one or more preservatives. Suitable dispersing
or wetting agents and suspending agents are exemplified by those
already mentioned above. Additional excipients such as sweetening,
flavoring and coloring agents, may also be present.
[0381] The pharmaceutical compositions of the invention may also be
in the form of oil-in-water emulsions. The oily phase may be a
vegetable oil, such as olive oil or arachis oil, or a mineral oil,
such as for example liquid paraffin or a mixture of any of these.
Suitable emulsifying agents may be, for example,
naturally-occurring gums such as gum acacia or gum tragacanth,
naturally-occurring phosphatides such as soya bean, lecithin,
esters or partial esters derived from fatty acids and hexitol
anhydrides (for example sorbitan monooleate) and condensation
products of the said partial esters with ethylene oxide such as
polyoxyethylene sorbitan monooleate. The emulsions may also contain
sweetening, flavoring and preservative agents.
[0382] Syrups and elixirs may be formulated with sweetening agents
such as glycerol, propylene glycol, sorbitol, aspartame or sucrose,
and may also contain a demulcent, preservative, flavoring and/or
coloring agent.
[0383] Suppository formulations may be prepared by mixing the
active ingredient with a suitable non-irritating excipient that is
solid at ordinary temperatures but liquid at the rectal temperature
and will therefore melt in the rectum to release the drug. Suitable
excipients include, for example, cocoa butter and polyethylene
glycols. Formulations suitable for vaginal administration may be
presented as pessaries, tampons, creams, gels, pastes, foams or
spray formulations containing in addition to the active ingredient
such carriers as are known in the art to be appropriate.
[0384] Topical formulations, such as creams, ointments, gels and
aqueous or oily solutions or suspensions, may generally be obtained
by formulating an active ingredient with a conventional, topically
acceptable, vehicle or diluent using conventional procedures well
known in the art.
[0385] Compositions for transdermal administration may be in the
form of those transdermal skin patches that are well known to those
of ordinary skill in the art.
[0386] Formulations suitable for intrapulmonary or nasal
administration have a particle size for example in the range of 0.1
to 500 microns (including particle sizes in a range between 0.1 and
500 microns in increments microns such as 0.5, 1, 30 microns, 35
microns, etc.), which is administered by rapid inhalation through
the nasal passage or by inhalation through the mouth so as to reach
the alveolar sacs. Suitable formulations include aqueous or oily
solutions of the active ingredient. Formulations suitable for
aerosol or dry powder administration may be prepared according to
conventional methods and may be delivered with other therapeutic
agents such as compounds heretofore used in the treatment or
prophylaxis disorders as described below.
[0387] The pharmaceutical composition (or formulation) for
application may be packaged in a variety of ways depending upon the
method used for administering the drug. For example, an article for
distribution can include a container having deposited therein the
pharmaceutical formulation in an appropriate form. Suitable
containers are well known to those skilled in the art and include
materials such as bottles (plastic and glass), sachets, ampoules,
plastic bags, metal cylinders, and the like. The container may also
include a tamper-proof assemblage to prevent indiscreet access to
the contents of the package. In addition, the container has
deposited thereon a label that describes the contents of the
container. The label may also include appropriate warnings. The
formulations may also be packaged in unit-dose or multi-dose
containers, for example sealed ampoules and vials, and may be
stored in a freeze-dried (lyophilized) condition requiring only the
addition of the sterile liquid carrier, for example water, for
injection immediately prior to use. Extemporaneous injection
solutions and suspensions are prepared from sterile powders,
granules and tablets of the kind previously described. Preferred
unit dosage formulations are those containing a daily dose or unit
daily sub-dose, as herein above recited, or an appropriate fraction
thereof, of the active ingredient.
[0388] The invention further provides veterinary compositions
comprising a compound of Formula I together with a veterinary
carrier therefore. Veterinary carriers are materials useful for the
purpose of administering the composition and may be solid, liquid
or gaseous materials which are otherwise inert or acceptable in the
veterinary art and are compatible with the active ingredient. These
veterinary compositions may be administered parenterally, orally or
by any other desired route.
[0389] The amount of a compound of this invention that is combined
with one or more excipients to produce a single dosage form will
necessarily vary depending upon the subject treated, the severity
of the disorder or condition, the rate of administration, the
disposition of the compound and the discretion of the prescribing
physician. In one embodiment, a suitable amount of a compound of
Formula I is administered to a mammal in need thereof.
Administration in one embodiment occurs in an amount between about
0.001 mg/kg of body weight to about 60 mg/kg of body weight per
day. In another embodiment, administration occurs in an amount
between 0.5 mg/kg of body weight to about 40 mg/kg of body weight
per day. In some instances, dosage levels below the lower limit of
the aforesaid range may be more than adequate, while in other cases
still larger doses may be employed without causing any harmful side
effect, provided that such larger doses are first divided into
several small doses for administration throughout the day. For
further information on routes of administration and dosage regimes,
see Chapter 25.3 in Volume 5 of Comprehensive Medicinal Chemistry
(Corwin Hansch; Chairman of Editorial Board), Pergamon Press 1990,
which is specifically incorporated herein by reference.
[0390] The invention further provides veterinary compositions
comprising at least one active ingredient as above defined together
with a veterinary carrier therefore. Veterinary carriers are
materials useful for the purpose of administering the composition
and may be solid, liquid or gaseous materials which are otherwise
inert or acceptable in the veterinary art and are compatible with
the active ingredient. These veterinary compositions may be
administered parenterally, orally or by any other desired
route.
[0391] The amount of a compound of this invention that is combined
with one or more excipients to produce a single dosage form will
necessarily vary depending upon the subject treated, the severity
of the disorder or condition, the rate of administration, the
disposition of the compound and the discretion of the prescribing
physician. In one embodiment, a suitable amount of a compound of
Formula I is administered to a mammal in need thereof.
Administration in one embodiment occurs in an amount between about
0.001 mg/kg of body weight to about 60 mg/kg of body weight per
day. In another embodiment, administration occurs in an amount
between 0.5 mg/kg of body weight to about 40 mg/kg of body weight
per day. In some instances, dosage levels below the lower limit of
the aforesaid range may be more than adequate, while in other cases
still larger doses may be employed without causing any harmful side
effect, provided that such larger doses are first divided into
several small doses for administration throughout the day. For

which is specifically incorporated herein by reference.
[0392] Articles of Manufacture
[0393] In another embodiment of the invention, an article of
manufacture, or "kit", containing materials useful for the
treatment of the disorders described above is provided. In one
embodiment, the kit comprises a container comprising a compound of
Formula I, or a solvate, metabolite, or pharmaceutically acceptable
salt or prodrug thereof. The kit may further comprise a label or
package insert on or associated with the container. The term
"package insert" is used to refer to instructions customarily
included in commercial packages of therapeutic products, that
contain information about the indications, usage, dosage,
administration, contraindications and/or warnings concerning the
use of such therapeutic products. In one embodiment, the label or
package inserts indicates that the composition comprising a
compound of Formula I can be used to treat one or more of the
diseases or disorders disclosed herein.
[0394] In one embodiment, the kit further comprises a container.
Suitable containers include, for example, bottles, vials, syringes,
blister pack, etc. The container may be formed from a variety of
materials such as glass or plastic. The container may hold a
compound of Formula I or a formulation thereof which is effective
for treating one or more diseases or disorders disclosed herein and
may have a sterile access port (for example, the container may be
an intravenous solution bag or a vial having a stopper pierceable
by a hypodermic injection needle).
[0395] The kit may further comprise directions for the
administration of the compound of Formula I and, if present, the
second pharmaceutical formulation. For example, when the kit
comprises a first composition comprising a compound of Formula I
and a second pharmaceutical formulation, the kit may further
comprise directions for the simultaneous, sequential or separate
administration of the first and second pharmaceutical compositions
to a patient in need thereof.
[0396] In another embodiment, the kits are suitable for the
delivery of solid oral forms of a compound of Formula I, such as
tablets or capsules. Such a kit can include a number of unit
dosages. Such kits can include a card having the dosages oriented
in the order of their intended use. An example of such a kit is a
"blister pack". Blister packs are well known in the packaging
industry and are widely used for packaging pharmaceutical unit
dosage forms. If desired, a memory aid can be provided, for example
in the form of numbers, letters, or other markings or with a
calendar insert, designating the days in the treatment schedule in
which the dosages can be administered.
[0397] According to one embodiment, an article of manufacture may
comprise (a) a first container with a compound of Formula I
contained therein; and optionally (b) a second container with a
second pharmaceutical formulation contained therein, wherein the
second pharmaceutical formulation comprises a second compound
having, for example, antihyperproliferative activity.
Alternatively, or additionally, the article of manufacture may
further comprise a third container comprising a
pharmaceutically-acceptable buffer, such as bacteriostatic water
for injection (BWFI), phosphate-buffered saline, Ringer's solution
and dextrose solution. It may further include other materials
desirable from a commercial and user standpoint, including other
buffers, diluents, filters, needles, and syringes.
[0398] In certain other embodiments wherein the kit comprises a
composition of Formula I and a second therapeutic agent, the kit
may comprise a container for containing the separate compositions
such as a divided bottle or a divided foil packet, however, the
separate compositions may also be contained within a single,
undivided container. Typically, the kit comprises directions for
the administration of the separate components. The kit form is
particularly advantageous when the separate components are
preferably administered in different dosage forms (e.g., oral and
parenteral), are administered at different dosage intervals, or
when titration of the individual components of the combination is
desired by the prescribing physician.
BIOLOGICAL EXAMPLES
Example A
EGFR/ErbB2 Enzymatic Assays
[0399] Thermo LabSystems Immulon 4HBX 96-well plates are coated by
incubation overnight at room temperature with 100 .mu.L per well of
0.25 mg/mL Poly (Glu, Tyr) 4:1 (PGT) (Sigma Chemical Co., St.
Louis, Mo.) in PBS (phosphate buffered saline). Excess PGT is
removed by aspiration, and the plate is washed three times with
wash buffer (0.1% Tween 20 in PBS). The kinase reaction is
performed in 100 .mu.L of 50 mM HEPES (pH 7.3) containing 125 mM
sodium chloride, 24 mM magnesium chloride, 0.1 mM sodium
orthovanadate, 15 .mu.M ATP (adenosine triphosphate) and 0.3
units/mL EGFR (epidermal growth factor receptor) (BIOMOL Research
Laboratories, Inc., Plymouth Meeting, Pa.). The compound in DMSO
(dimethylsulfoxide) is added to give a final DMSO concentration of
about 1%. Phosporylation is initiated by the addition of ATP and
incubated for 30 minutes at room temperature. The kinase reaction
is terminated by aspiration of the reaction mixture and subsequent
washing with wash buffer (see above). Phosphorylated PGT is
detected by 30 incubation with 100 .mu.L per well HRP conjugated
PY20 antiphosphotyrosine antibody (Zymed Laboratories, Inc., South
San Francisco, Calif.) diluted to 0.2 .mu.g/mL in 3% BSA and 0.05%
Tween 20 in PBS. Antibody is removed by aspiration, and the plate
is washed with wash buffer. The colorimetric signal is developed by
the addition of 100 .mu.L per well TMB Microwell Peroxidase
Substrate (Kirkegaard and Perry, Gaithersburg, Md.), and stopped by
the addition of 100 .mu.L per well 1M phosphoric acid.
Phosphotyrosine in measured by absorbance at 450 nm.
[0400] The ErbB2 kinase is as above using 250 ng/mL erbB2
intracellular domain in place of EGFR. The intracellular domain of
the ErbB2 tyrosine kinase (amino acids 691-1255) is expressed as a
his-tagged protein in Baculovirus and purified by nickel chelating,
ion exchange and size exclusion chromatography.
[0401] Compounds of the present invention have IC.sub.50's from
less than 1 nM to 50 mM.
Example B
Cellular ErbB2 Phosphorylation Assay
[0402] The cellular potency of compounds is measured by the
inhibition of phosphorylated erbB2 (p-erbB2) in the BT474 cell line
which overexpresses erbB2 and consequently, has high basal levels
of p-erbB2. BT474 cells are plated in 96 well plates and incubated
overnight at 37.degree. C./5% CO.sub.2. The next day, the medium is
replaced with serum-free medium, followed by the addition of
compounds for 2 hours. Cells are lysed by the addition of lysis
buffer and freezing at -80.degree. C. Thawed and clarified lysates
are then added to 96-well plates that are coated with an anti-erbB2
antibody. Phosphorylated erbB2 is detected with a phospho-tyrosine
antibody using an ELISA format. Compounds of the present invention
have IC.sub.50's of less than 1 .mu.M in this assay.
Example C
Cellular EGFR Phosphorylation Assay
[0403] This assay measures the inhibition of EGF-induced
phosphorylated EGFR (pEGFR) in the A431 cell line which
overexpresses EGFR. Cells are plated in 96 well plates and
incubated for 6-8 hrs at 37.degree. C./5% CO.sub.2 before being
serum-starved overnight. The next day, compounds are added for 1
hour before a 10 minute induction with EGF. Cells are lysed by the
addition of lysis buffer and freezing at -80.degree. C. Thawed and
clarified lysates are then added to 96-well plates that are coated
with an anti-EGFR antibody; p-EGFR is then detected by a
phospho-tyrosine antibody using an ELISA format.

oxazol-5-yloxy)phenyl)quinazoline-4,6-diamine
Step A: Preparation of
N'-(2-cyano-4-nitrophenyl)-N,N-dimethylformamidine
[0409] A mixture of 2-amino-5-nitrobenzonitrile (30.0 g, 184 mmol)
and dimethoxy-N,N-dimethylmethanamine (29.6 mL, 223 mmol) was
heated to 100.degree. C. for 2 hours. The reaction mixture was
concentrated under reduced pressure and dissolved in
dichloromethane. The solution was run through a silica plug washing
the plug with ethyl acetate. The filtrate was concentrated under
reduced pressure, stirred with ether and filtered to provide the
