PYRAZOLO[1,5-a]PYRIMIDINES USEFUL AS INHIBITORS OF PROTEIN
KINASES
TECHNICAL FIELD OF THE INVENTION
[0100] The present invention relates to compounds useful as inhibitors of protein
kinases, particularly Tec family kinases, Aurora ldnases and c-Met. The invention also
provides pharmaceutically acceptable compositions comprising the compounds of the
invention and methods of using the compositions in the treatment of various disorders.
The invention also provides processes for preparing the compounds of the invention.
BACKGROUND OF THE INVENTION
[0101] The Tec family of non-receptor tyrosine kinases plays a central role in
signalling through antigen-receptors such as the TCR, BCR and Fce receptors and are
essential for T cell activation. Deletion of Itk in mice results in reduced T cell receptor
(TCR)-induced proliferation and secretion of the cytokines IL-2, IL-4, IL-5, DL-10 and
EFN-γ. Itk has been implicated in allergic asthma and atopic dermatitis.
[0102] Tec family ldnases are also essential for B cell development and activation.
Patients with mutations in Btk have a profound block in B cell development, resulting in
the almost complete absence of B lymphocytes and plasma cells, severely reduced Ig
levels and a profound inhibition of humoral response to recall antigens. Btk deletion in
mice has a profound effect on B cell proliferation induced by anti-IgM, and inhibits
immune responses to thymus-independent type II antigens.
[0103] Tec kinases also play a role in mast cell activation through the high-affinity
IgE receptor (FCERI). Itk and Btk are expressed in mast cells and are activated by FceRI
cross-linking. Btk deficient murine mast cells have reduced degranulation and decreased

WO 2006/052913 PCT/US2005/040344
-2-
production of proinflammatory cytokines following FceRI cross-linking. Btk deficiency
also results in a decrease of macrophage effector functions.
[0104] The Aurora proteins are a family of three highly related serine/threonine
kinases (termed Aurora-A, -B and -C) that are essential for a cell's progression through
the mitotic phase of the cell cycle. Specifically Aurora-A plays a crucial role in
centrosome maturation and segregation, formation of the mitotic spindle, and faithful
segregation of chromosomes. Aurora-B is a chromosomal passenger protein that plays a
central role in regulating the alignment of chromosomes on the meta-phase plate, in the
spindle assembly checkpoint, and also in the correct completion of cytokinesis.
[0105] Overexpression of Aurora-A (Aurora-2), Aurora-B (Aurora-1) or Aurora-C
has been observed in a range of human cancers including colorectal, ovarian, gastric, and
invasive duct adenocarcinomas.
[0106] A number of studies have now demonstrated that depletion or inhibition of
Aurora-A or -B in human cancer cell lines by siRNA, dominant negative or neutralizing
antibodies, disrupts progression through mitosis with accumulation of cells with 4N
DNA. In some cases, this is followed by endoreduplication and cell death.
[0107] The c-Met receptor tyrosine kinase is overexpressed in a significant
percentage of human cancers and is amplified during the transition between primary
tumors and metastasis. The various cancers in which c-Met is implicated include, but are
not limited to, gastric adenocarcinoma, renal cancer, small cell lung carcinoma,
colorectal cancer, colon cancer, prostate cancer, brain cancer, liver cancer, pancreatic
cancer, and breast cancer. c-Met is also implicated in atherosclerosis, lung fibrosis,
allergic disorders, autoimmune disorders, and conditions associated with organ
transplantation.
[0108] Accordingly, there is a great need to develop compounds useful as inhibitors
of protein kinases. In particular, it would be desirable to develop compounds that are
useful as inhibitors of Tec family (e.g.,Tec, Btk, Itk/Emt/Tsk, Bmx, Txk/Rlk) and Aurora
family protein kinases, as well as c-Met, particularly given the inadequate treatments
currently available for the majority of the disorders implicated in their activation.

morpholin-4-yl group; and b) two independent occurrences of R° (or R+, or any other
variable similarly defined herein) that are bound to different atoms and are taken together
with both of those atoms to form a ring, for example where a phenyl group is substituted

substituent only represents substitution on the ring to which it is attached. For example,
in Figure d, Y is an optionally substituent for ring A only, and X is an optional
substituent for ring B only.

[0181] Unless otherwise stated, structures depicted herein are also meant to include
all isomeric (e.g., enantiomeric, diastereomeric, and geometric (or conformational))
forms of the structure; for example, the R and S configurations for each asymmetric
center, (Z) and (E) double bond isomers, and (Z) and (E) conformational isomers.
Therefore, single stereochemical isomers as well as enantiomeric, diastereomeric, and
geometric (or conformational) mixtures of the present compounds are within the scope of
the invention. Unless otherwise stated, all tautomeric forms of the compounds of the
invention are within the scope of the invention. Additionally, unless otherwise stated,
structures depicted herein are also meant to include compounds that differ only in the
presence of one or more isotopically enriched atoms. For example, compounds having
the present structures except for the replacement of hydrogen by deuterium or tritium, or
the replacement of a carbon by a 13C- or 14C-enriched carbon are within the scope of this
invention. Such compounds are useful, for example, as analytical tools or probes in
biological assays.

[0210] As discussed above, the present invention provides compounds that are
inhibitors of protein kinases, and thus the present compounds are useful for the treatment
of diseases, disorders, and conditions including, but not limited to an autoimmune,
inflammatory, proliferative, or hyperproliferative disease or an immunologically-
mediated disease. Accordingly, in another aspect of the present invention,
pharmaceutically acceptable compositions are provided, wherein these compositions
comprise any of the compounds as described herein, and optionally comprise a
pharmaceutically acceptable carrier, adjuvant or vehicle. In certain embodiments, these
compositions optionally further comprise one or more additional therapeutic agents.
[0211] It will also be appreciated that certain of the compounds of present invention
can exist in free form for treatment, or where appropriate, as a pharmaceutically
acceptable derivative thereof. According to the present invention, a pharmaceutically
acceptable derivative includes, but is not limited to, pharmaceutically acceptable salts,
esters, salts of such esters, or any other adduct or derivative which upon administration
to a patient in need is capable of providing, directly or indirectly, a compound as
otherwise described herein, or a metabolite or residue thereof.
[0212] As used herein, the term "pharmaceutically acceptable salt" refers to those
salts which are, within the scope of sound medical judgment, suitable for use in contact

WO 2006/052913 PCT/US2005/040344
-212-
with the tissues of humans and lower animals without undue toxicity, irritation, allergic
response and the like, and are commensurate with a reasonable benefit/risk ratio. A
"pharmaceutically acceptable salt" means any non-toxic salt or salt of an ester of a
compound of this invention that, upon administration to a recipient, is capable of
providing, either directly or indirectly, a compound of this invention or an inhibitorily
active metabolite or residue thereof. As used herein, the term "inhibitorily active
metabolite or residue thereof" means that a metabolite or residue thereof is also an
inhibitor of a Tec family (e.g.,Tec, Btk, Itk/Emt/Tsk, Bmx, Txk/Rlk) protein kinase, an
Aurora family kinase or c-Met.
[0213] Pharmaceutically acceptable salts are well known in the art. For example, S.
M. Berge et al., describe pharmaceutically acceptable salts in detail in J. Pharmaceutical
Sciences, 1977, 66,1-19, incorporated herein by reference. Pharmaceutically acceptable
salts of the compounds of this invention include those derived from suitable inorganic
and organic acids and bases. Examples of pharmaceutically acceptable, nontoxic acid
addition salts are salts of an amino group formed with inorganic acids such as
hydrochloric acid, hydrobromic acid, phosphoric acid, sulfuric acid and perchloric acid
or with organic acids such as acetic acid, oxalic acid, maleic acid, tartaric acid, citric
acid, succinic acid or malonic acid or by using other methods used in the art such as ion
exchange. Other pharmaceutically acceptable salts include adipate, alginate, ascorbate,
aspartate, benzenesulfonate, benzoate, bisulfate, borate, butyrate, camphorate,
camphorsulfonate, citrate, cyclopentanepropionate, digluconate, dodecylsulfate,
ethanesulfonate, formate, fumarate, glucoheptonate, glycerophosphate, gluconate,
hemisulfate, heptanoate, hexanoate, hydroiodide, 2-hydroxy-ethanesulfonate,
lactobionate, lactate, laurate, lauryl sulfate, malate, maleate, malonate, methanesulfonate,
2-naphthalenesulfonate, nicotinate, nitrate, oleate, oxalate, palmitate, pamoate, pectinate,
persulfate, 3-phenylpropionate, phosphate, picrate, pivalate, propionate, stearate,
succinate, sulfate, tartrate, thiocyanate, p-toluenesulfonate, undecanoate, valerate salts,
and the like. Salts derived from appropriate bases include alkali metal, alkaline earth
metal, ammonium and N+(Ci.4alkyl)4 salts. This invention also envisions the
quaternization of any basic nitrogen-containing groups of the compounds disclosed
herein. Water or oil-soluble or dispersible products may be obtained by such
quaternization. Representative alkali or alkaline earth metal salts include sodium,

WO 2006/052913 PCT/US2005/040344
-213-
lithium, potassium, calcium, magnesium, and the like. Further pharmaceutically
acceptable salts include, when appropriate, nontoxic ammonium, quaternary ammonium,
and amine cations formed using counterfoils such as halide, hydroxide, carboxylate,
sulfate, phosphate, nitrate, loweralkyl sulfonate and aryl sulfonate.
[0214] As described above, the pharmaceutically acceptable compositions of the
present invention additionally comprise a pharmaceutically acceptable carrier, adjuvant,
or vehicle, which, as used herein, includes any and all solvents, diluents, or other liquid
vehicle, dispersion or suspension aids, surface active agents, isotonic agents, thickening
or emulsifying agents, preservatives, solid binders, lubricants and the like, as suited to
the particular dosage form desired. Remington's Pharmaceutical Sciences, Sixteenth
Edition, E. W. Martin (Mack Publishing Co., Easton, Pa., 1980) discloses various
carriers used in formulating pharmaceutically acceptable compositions and known
techniques for the preparation thereof. Except insofar as any conventional canier
medium is incompatible with the compounds of the invention, such as by producing any
undesirable biological effect or otherwise interacting in a deleterious manner with any
other component(s) of the pharmaceutically acceptable composition, its use is
contemplated to be within the scope of this invention. Some examples of materials which
can serve as pharmaceutically acceptable carriers include, but are not limited to, ion
exchangers, alumina, aluminum stearate, lecithin, serum proteins, such as human serum
albumin, buffer substances such as phosphates, glycine, sorbic acid, or potassium
sorbate, partial glyceride mixtures of saturated vegetable fatty acids, water, salts or
electrolytes, such as protamine sulfate, disodium hydrogen phosphate, potassium
hydrogen phosphate, sodium chloride, zinc salts, colloidal silica, magnesium trisilicate,
polyvinyl pyrrolidone, polyacrylates, waxes, polyethylene-polyoxypropylene-block
polymers, wool fat, sugars such as lactose, glucose and sucrose; starches such as corn
starch and potato starch; cellulose and its derivatives such as sodium carboxymethyl
cellulose, ethyl cellulose and cellulose acetate; powdered tragacanth; malt; gelatin; talc;
excipients such as cocoa butter and suppository waxes; oils such as peanut oil,
cottonseed oil; safflower oil; sesame oil; olive oil; corn oil and soybean oil; glycols; such
a propylene glycol or polyethylene glycol; esters such as ethyl oleate and ethyl laurate;
agar; buffering agents such as magnesium hydroxide and aluminum hydroxide; alginic
acid; pyrogen-free water; isotonic saline; Ringer's solution; ethyl alcohol, and phosphate

WO 2006/052913 PCT/US2005/040344
-214-
buffer solutions, as well as other non-toxic compatible lubricants such as sodium lauryl
sulfate and magnesium stearate, as well as coloring agents, releasing agents, coating
agents, sweetening, flavoring and perfuming agents, preservatives and antioxidants can
also be present in the composition, according to the judgment of the formulator.
[0215] In yet another aspect, a method for the treatment or lessening the severity
of a Tec family (e.g.,Tec, Btk, Itk/Emt/Tsk, Bmx, Txk/Rlk)-mediated disease, an Aurora
family-mediated disease or a c-Met-mediated disease, is provided comprising
administering an effective amount of a compound, or a pharmaceutically acceptable
composition comprising a compound to a subject in need thereof. In certain
embodiments of the present invention an "effective amount" of the compound or
pharmaceutically acceptable composition is that amount effective for a Tec family
(e.g.,Tec, Btk, Itk/Emt/Tsk, Bmx, Txk/Rlk)-mediated disease, an Aurora family-
mediated disease or a c-Met-mediated disease. The compounds and compositions,
according to the method of the present invention, may be administered using any amount
and any route of administration effective for treating or lessening the severity of a Tec
family (e.g.,Tec, Btk, Itk/Emt/Tsk, Bmx, Txk/Rlk)-mediated disease, an Aurora family-
mediated disease or a c-Met-mediated disease. The exact amount required will vary
from subject to subject, depending on the species, age, and general condition of the
subject, the severity of the infection, the particular agent, its mode of administration, and
the like. The compounds of the invention are preferably formulated in dosage unit form
for ease of administration and uniformity of dosage. The expression "dosage unit form"
as used herein refers to a physically discrete unit of agent appropriate for the patient to be
treated. It will be understood, however, that the total daily usage of the compounds and
compositions of the present invention will be decided by the attending physician within
the scope of sound medical judgment. The specific effective dose level for any particular
patient or organism will depend upon a variety of factors including the disorder being
treated and the severity of the disorder; the activity of the specific compound employed;
the specific composition employed; the age, body weight, general health, sex and diet of
the patient; the time of administration, route of administration, and rate of excretion of
the specific compound employed; the duration of the treatment; drugs used in
combination or coincidental with the specific compound employed, and like factors well

WO 2006/052913 PCT/US2005/040344
-215-
known in the medical arts. The term "patient", as used herein, means an animal,
preferably a mammal, and most preferably a human.
[0216] The pharmaceutically acceptable compositions of this invention can be
administered to humans and other animals orally, rectally, parenterally, intracisternally,
intravaginally, intraperitoneally, topically (as by powders, ointments, or drops), bucally,
as an oral or nasal spray, or the like, depending on the severity of the infection being
treated. In certain embodiments, the compounds of the invention may be administered
orally or parenterally at dosage levels of about 0.01 mg/kg to about 50 mg/kg and
preferably from about 1 mg/kg to about 25 mg/kg, of subject body weight per day, one or
more times a day, to obtain the desired therapeutic effect.
[0217] Liquid dosage forms for oral administration include, but are not limited to,
pharmaceutically acceptable emulsions, microemulsions, solutions, suspensions, syrups
and elixirs. In addition to the active compounds, the liquid dosage forms may contain
inert diluents commonly used in the art such as, for example, water or other solvents,
solubilizing agents and emulsifiers such as ethyl alcohol, isopropyl alcohol, ethyl
carbonate, ethyl acetate, benzyl alcohol, benzyl benzoate, propylene glycol, 1,3-butylene
glycol, dimethylformamide, oils (in particular, cottonseed, groundnut, com, germ, olive,
castor, and sesame oils), glycerol, tetrahydrofurfuryl alcohol, polyethylene glycols and
fatty acid esters of sorbitan, and mixtures thereof. Besides inert diluents, the oral
compositions can also include adjuvants such as wetting agents, emulsifying and
suspending agents, sweetening, flavoring, and perfuming agents.
[0218] Injectable preparations, for example, sterile injectable aqueous or oleaginous
suspensions may be formulated according to the known art using suitable dispersing or
wetting agents and suspending agents. The sterile injectable preparation may also be a
sterile injectable solution, suspension or emulsion in a nontoxic parenterally acceptable
diluent or solvent, for example, as a solution in 1,3-butanediol. Among the acceptable
vehicles and solvents that may be employed are water, Ringer's solution, U.S.P. and
isotonic sodium chloride solution. In addition, sterile, fixed oils are conventionally
employed as a solvent or suspending medium. For this purpose any bland fixed oil can
be employed including synthetic mono- or diglycerides. In addition, fatty acids such as
oleic acid are used in the preparation of injectables.

WO 2006/052913 PCT/US2005/040344
-216-
[0219] The injectable formulations can be sterilized, for example, by filtration
through a bacterial-retaining filter, or by incorporating sterilizing agents in the form of
sterile solid compositions which can be dissolved or dispersed in sterile water or other
sterile injectable medium prior to use.
[0220] In order to prolong the effect of a compound of the present invention, it is
often desirable to slow the absorption of the compound from subcutaneous or
intramuscular injection. This may be accomplished by the use of a liquid suspension of
crystalline or amorphous material with poor water solubility. The rate of absorption of
the compound then depends upon its rate of dissolution that, in turn, may depend upon
crystal size and crystalline form. Alternatively, delayed absorption of a parenterally
administered compound form is accomplished by dissolving or suspending the
compound in an oil vehicle. Injectable depot forms are made by forming microencapsule
matrices of the compound in biodegradable polymers such as polylactide-polyglycolide.
Depending upon the ratio of compound to polymer and the nature of the particular
polymer employed, the rate of compound release can be controlled. Examples of other
biodegradable polymers include poly(orthoesters) and poly(anhydrides). Depot injectable
formulations are also prepared by entrapping the compound in liposomes or
microemulsions that are compatible with body tissues.
[0221] Compositions for rectal or vaginal administration are preferably suppositories
which can be prepared by mixing the compounds of this invention with suitable non-
irritating excipients or earners such as cocoa butter, polyethylene glycol or a suppository
wax which are solid at ambient temperature but liquid at body temperature and therefore
melt in the rectum or vaginal cavity and release the active compound.
[0222] Solid dosage forms for oral administration include capsules, tablets, pills,
powders, and granules. In such solid dosage forms, the active compound is mixed with at
least one inert, pharmaceutically acceptable excipient or carrier such as sodium citrate or
dicalcium phosphate and/or a) fillers or extenders such as starches, lactose, sucrose,
glucose, mannitol, and silicic acid, b) binders such as, for example,
carboxymethylcellulose, alginates, gelatin, polyvinylpyrrolidinone, sucrose, and acacia,
c) humectants such as glycerol, d) disintegrating agents such as agar--agar, calcium
carbonate, potato or tapioca starch, alginic acid, certain silicates, and sodium carbonate,
e) solution retarding agents such as paraffin, f) absorption accelerators such as

WO 2006/052913 PCT/US2005/040344
-217-
quaternary ammonium compounds, g) wetting agents such as, for example, cetyl alcohol
and glycerol monostearate, h) absorbents such as kaolin and bentonite clay, and i)
lubricants such as talc, calcium stearate, magnesium stearate, solid polyethylene glycols,
sodium lauryl sulfate, and mixtures thereof. In the case of capsules, tablets and pills, the
dosage form may also comprise buffering agents.
[0223] Solid compositions of a similar type may also be employed as fillers in soft
and hard-filled gelatin capsules using such excipients as lactose or milk sugar as well as
high molecular weight polyethylene glycols and the like. The solid dosage forms of
tablets, dragees, capsules, pills, and granules can be prepared with coatings and shells
such as enteric coatings and other coatings well known in the pharmaceutical
formulating art. They may optionally contain opacifying agents and can also be of a
composition that they release the active ingredient(s) only, or preferentially, in a certain
part of the intestinal tract, optionally, in a delayed manner. Examples of embedding
compositions that can be used include polymeric substances and waxes. Solid
compositions of a similar type may also be employed as fillers in soft and hard-filled
gelatin capsules using such excipients as lactose or milk sugar as well as high molecular
weight polethylene glycols and the like.
[0224] The active compounds can also be in micro-encapsulated form with one or
more excipients as noted above. The solid dosage forms of tablets, dragees, capsules,
pills, and granules can be prepared with coatings and shells such as enteric coatings,
release controlling coatings and other coatings well known in the pharmaceutical
formulating art. In such solid dosage forms the active compound may be admixed with at
least one inert diluent such as sucrose, lactose or starch. Such dosage forms may also
comprise, as is normal practice, additional substances other than inert diluents, e.g.,
tableting lubricants and other tableting aids such a magnesium stearate and
microcrystalline cellulose. In the case of capsules, tablets and pills, the dosage forms
may also comprise buffering agents. They may optionally contain opacifying agents and
can also be of a composition that they release the active ingredient(s) only, or
preferentially, in a certain part of the intestinal tract, optionally, in a delayed manner.
Examples of embedding compositions that can be used include polymeric substances and
waxes.

WO 2006/052913 PCT/US2005/040344

[0225] Dosage forms for topical or transdermal administration of a compound of this
invention include ointments, pastes, creams, lotions, gels, powders, solutions, sprays,
inhalants or patches. The active component is admixed under sterile conditions with a
pharmaceutically acceptable carrier and any needed preservatives or buffers as may be
required. Ophthalmic formulation, ear drops, and eye drops are also contemplated as
being within the scope of this invention. Additionally, the present invention contemplates
the use of transdermal patches, which have the added advantage of providing controlled
delivery of a compound to the body. Such dosage forms can be made by dissolving or
dispensing the compound in the proper medium. Absorption enhancers can also be used
to increase the flux of the compound across the skin. The rate can be controlled by either
providing a rate controlling membrane or by dispersing the compound in a polymer
matrix or gel.
[0226] As described generally above, the compounds of the invention are useful as
inhibitors of protein kinases. In one embodiment, the compounds and compositions of
the invention are inhibitors of one or more of a Tec family (e.g.,Tec, Btk, Itk/Emt/Tsk,
Bmx, Txk/Rlk) kinase, an Aurora family kinase or a c-Met family kinase, and thus,
without wishing to be bound by any particular theory, the compounds and compositions
are particularly useful for treating or lessening the severity of a disease, condition, or
disorder where activation of one or more of a Tec family (e.g.,Tec, Btk, Itk/Emt/Tsk,
Bmx, Txk/Rlk) kinase, an Aurora family kinase or c-Met is implicated in the disease,
condition, or disorder. When activation of Tec family (e.g.,Tec, Btk, Itk/Emt/Tsk, Bmx,
Txk/Rlk) kinase, an Aurora family kinase or c-Met is implicated in a particular disease,
condition, or disorder, the disease, condition, or disorder may also be referred to as a
"Tec family (e.g.,Tec, Btk, Itk/Emt/Tsk, Bmx, Txk/Rlk)-mediated disease", "an Aurora
family-mediated disease" or "a c-Met-mediated disease" or disease symptom.
Accordingly, in another aspect, the present invention provides a method for treating or
lessening the severity of a disease, condition, or disorder where activation or one or
more of Tec family (e.g.,Tec, Btk, Itk/Emt/Tsk, Bmx, Txk/Rlk) kinase, an Aurora family
kinase or c-Met is implicated in the disease state.
[0227] The activity of a compound utilized in this invention as an inhibitor of a Tec
family (e.g.,Tec, Btk, Itk/Emt/Tsk, Bmx, Txk/Rlk) kinase, an Aurora family kinase or c-
Met may be assayed in vitro, in vivo or in a cell line. In vitro assays include assays that

WO 2006/052913 PCT/US2005/040344
-219-
determine inhibition of either the phosphorylation activity or ATPase activity of
activated Tec family (e.g.,Tec, Btk, Itk/Emt/Tsk, Bmx, Txk/Rlk) kinase, an Aurora
family kinase or c-Met. Alternate in vitro assays quantitate the ability of the inhibitor to
bind to a Tec family (e.g.,Tec, Btk, Itk/Emt/Tsk, Bmx, Txk/Rlk) kinase, an Aurora
family kinase or c-Met. Inhibitor binding may be measured by radiolabelling the
inhibitor prior to binding, isolating the inhibitor/kinase complex and determining the
amount of radiolabel bound. Alternatively, inhibitor binding may be determined by
running a competition experiment where new inhibitors are incubated with a Tec family
(e.g.,Tec, Btk, Itk/Emt/Tsk, Bmx, Txk/Rlk) kinase, an Aurora family kinase or c-Met
bound to known radioligands.
[0228] The term "measurably inhibit", as used herein means a measurable change in
kinase activity between a sample comprising a compound of the invention and a kinase
of interest and an equivalent sample comprising the kinase in the absence of said
compound.
[0229] The term "Tec family tyrosine kinases-mediated condition", as used herein
means any disease or other deleterious condition in which Tec family kinases are known
to play a role. Such conditions include, without limitation, autoimmune, inflammatory,
proliferative, and hyperproliferative diseases and immunologically-mediated diseases
including rejection of transplanted organs or tissues and Acquired Immunodeficiency
Syndrome (AIDS).
[0230] For example, Tec family tyrosine kinases -mediated conditions include

patient a compound of the present invention, or a composition comprising said
compound.
[0240] The term "c-Met-mediated disease" or "c-Met-mediated condition", as used
herein, means any disease state or other deleterious condition in which c-Met is known to
play a role. The terms "c-Met-mediated disease" or "c-Met-mediated condition" also
mean those diseases or conditions that are alleviated by treatment with a c-Met inhibitor.
Such conditions include, without limitation, renal, gastric, colon, brain, breast, prostate,
and lung cancer, glioblastoma, atherosclerosis, lung fibrosis, conditions associated with
organ transplantation, allergic disorders, and autoimmune disorders.

organism, and includes, without limitation, cell cultures or extracts thereof; biopsied
material obtained from a mammal or extracts thereof; and blood, saliva, urine, feces,
semen, tears, or other body fluids or extracts thereof.
[0248] Inhibition of protein kinase, e.g., inhibition of c-Met, activity in a biological
sample is useful for a variety of purposes that are known to one of skill in the art.
Examples of such purposes include, but are not limited to, blood transfusion, organ-
transplantation, biological specimen storage, and biological assays.

acceptable compositions of the present invention can be employed in combination
therapies, that is, the compounds and pharmaceutically acceptable compositions can be
administered concurrently with, prior to, or subsequent to, one or more other desired
therapeutics or medical procedures. The particular combination of therapies (therapeutics
or procedures) to employ in a combination regimen will take into account compatibility
of the desired therapeutics and/or procedures and the desired therapeutic effect to be
achieved. It will also be appreciated that the therapies employed may achieve a desired
effect for the same disorder (for example, an inventive compound may be administered

WO 2006/052913 PCT/US2005/040344
-223-
concurrently with another agent used to treat the same disorder), or they may achieve
different effects (e.g., control of any adverse effects). As used herein, additional
therapeutic agents that are normally administered to treat or prevent a particular disease,
or condition, are known as "appropriate for the disease, or condition, being treated".
