PROTEIN KINASES
This application claims the benefit of Indian Provisional Patent Application No. 1262/CHE/2012 dated 30” March 2012 ail of which is hereby incorporated by reference.
FIELD OF THE INVENTION
The présent invention provides compounds useful as protein kinase modulators, methods of preparing them, pharmaceutical compositions containing them and methods of treatment, prévention and/or amelioration of kinase mediated diseases or disorders with them.
BACKGROUND OF THE INVENTION
In the recent past, immense research has been dedicated to the discovery and understanding of the structure and fondions of enzymes and bio-molecules associated with various diseases. One such important class of enzymes that has been the subject of extensive research is protein kinase.
In general, protein kinases represent a set of structurally related phosphory! transferases having conserved structures and catalytic fonctions. Thèse enzymes modify proteins by chemically adding phosphate groups (phosphorylation). Phosphorylation involves the removal of a phosphate group from ATP and covalently attaching it to amino acids that hâve a free hydroxyl group such as serine, threonine or tyrosine. Phosphorylation usually results in a functional change of the target protein (substrate) by altering enzyme activity, cellular localization or association with other proteins. Up to 30% of ali proteins may be modified by kinase activity.
This class of proteins are dassified into subsets depending upon the substrate they act upon, such as tyrosine kinase, serine/theronîne kinase, histidine kinase and the like. These proteins can also be dassified based on their localization into receptor tyrosine kinases (RTKs) or nonreceptor tyrosine kinases. '
Receptor tyrosine kinases (RTKs) hâve an extracellular portion, a transmembrane domain, and an intracellular portion, while non-receptor tyrosine kinases are entirely intracellular. Receptor tyrosine kinase mediated signal transdudion is typically inrtiated by an extracellular interaction . ASSIGNMENT

with a spécifie growth factor (ligand), followed by receptor dimerization, stimulation of the intrinsic protein tyrosine kinase activity, and phosphorylation of amino acid residues. The ensuing conformational change leads to the formation of complexes with a spectrum of cytoplasmic signalling molécules and facilitâtes a myriad of responses such as cell division, différentiation, metabolic effects, and changes in the extracellular microenvironment.
At présent, at least twenty (20) distinct RTK subfamilies hâve been identified. One subfamily of the RTKs is designated as the Met subfamily (c-Met, Ron and Sea). For a detailed discussion of protein kinases, see, Plowman et al., DN&P 7(6): 334-339, 1994, Blume- Jensen, P. et a!.. Nature, 2001, 411(6835):355-365 and Manning, G. et ai. Science, 2002, 298(5600): 19121934.
Kinases hâve also been dassified either based on the pathway or the diseases in which they are involved (visitwww.reactionbiology.com/pages/kinase.htm). c-Met has been identified as involved in oncogenesis.
Protein kinases exert their physiological fonctions through phosphorylation of proteins (or substrates) thereby modulating the cellular activities of the substrate in various biological contexts. Protein kinases are known to control a wide variety of biological processes such as cell growth, survival and différentiation, organ formation and morphogenesis, neovascularisation, tissue repair and régénération, ln addition to their fonctions in normal tissues/organs, many protein kinases also play specialized rôles in a host of human diseases including cancer. A subset of protein kinases (also referred to as oncogenic protein kinases), when dysregulated, can cause tumor formation and growth and contribute to tumor maintenance and progression (Blume- Jensen P et al, Nature, 2001,411(6835):355-365). Thus far, oncogenic protein kinases represent one of the largest and most attractive groups of protein targets for therapeutic intervention and drug development
Both receptor and non-receptor protein kinases hâve been found to be attractive targets for small molécule drug discovery due to their impact on cell physiology and signalling. Dysrégulation of protein kinase activity thus leads to altered cellular responses including uncontrolled cell growth associated with cancer, ln addition to oncological indications, altered kinase signalling is implicated in numerous other pathological diseases. These include, but are not limited to immunological disorders, cardiovascular diseases, inflammatory diseases, and degenerative diseases.
A significant number of tyrosine kinases (both receptor and nonreceptor) are associated with cancer (see Madhusudan S, Ganesan TS. Tyrosine kinase inhibitors in cancer therapy. Clin. Biochem., 2004, 37(7):618-35.). Clinical studies suggest that over expression or dysrégulation of tyrosine kinases may also be of prognostic value. For example, members of the HER family
of RTKs hâve been implicated in breast, colorectal, head and neck and lung cancer. Mutation of c-Kit tyrosine kinase is associated with decreased survival in gastrointestinal stromal tumors (GIST). In acute myelogenous leukemia, Flt-3 mutation predicts shorter disease free survival. VEGFR expression, which is important for tumor angiogenesis, ls associated with a lower survival rate in lung cancer. Tie-1 kinase expression is inversely correlated to survival in gastric cancer. BCR-Abl expression is an important predictor of response in chronic myelogenous leukemia while Src tyrosine kinase expression is co-related to the stage of colorectal cancer. Modulation (particularly inhibition) of cell prolifération and angiogenesis, the two key cellular processes needed for tumor growth and survival is an attractive goal for development of smallmolecule drugs (Matter A. Drug Disc. Technol., 2001, 6, 1005-1024). Anti-angiogenic therapy represents a potentially important approach for the treatment of solid tumors and other diseases associated with dysregulated vascularisation including ischémie coronary artery disease, diabetic retinopathy, psoriasis and rheumatoid arthritis. Similarly, cell antiproliférative agents are désirable to slow or inhibit the growth of tumors.
Some of the kinases implicated in cancer are c-Met, RON (récepteur d’origine nantais) receptor, Vascular Endothélial Growth Factor (VEGF) receptor, Epidermal growth factor receptor kinase (EGF-R kinase), Eph receptors, c-Kit, and Flt-3.
A number of small molécule kinase modulators hâve found their way into the dinic which either act selectively on either one or multiple kinases. These indude Gefitinib (AstraZeneca), a EGFR kinase inhibitor; Gfeevec (Novartis), a dual c-Kit and Abl kinase inhibitor approved for the treatment of Chronic Myeloid Leukemia (CML) and gastrointestinal stroma cancers; Dasatinib (BMS), a dual BCR/ABL and Src family tyrosine kinases inhibitor, and Sunitinib (Pfizer) a multi kinase inhibitor targeting PDGF-R.VEGF-R, RET, KIT(CD117), CSF-1R and flt-3.
The kinase, c-Met, is the prototypic member of a subfamily of heterodimeric receptor tyrosine kinases (RTKs) which indude Met, Ron and Sea (see Birchmeier, C. et a/., Nat. Rev. Mol. Cell Biol., 2003, 4(12):915-925; Christensen, J. G. et al.. Cancer Lett., 2005, 225(1): 1-26). Expression of c-Met occurs in a wide variety of cell types induding épithélial, endothélial and mesenchymal cells where activation of the receptor induces cell migration, invasion, prolifération and other biological activities assodated with invasive cell growth. As such, signal transduction through c-Met receptor activation is responsable for many of the characteristics of tumor cells.
The only high affinity endogenous ligand for c-Met is the hépatocyte growth factor (HGF), also known as scatter factor (SF). Binding of HGF to c-Met induces activation of the receptor via autophosphorylation resulting in an increase of receptor dépendent signalling, which promûtes cell growth and invasion. Both c-Met and HGF are widely expressed in a variety of organs, but
their expression is normally confined to cells of épithélial and mesenchymal origin. Anti-HGF antibodies or HGF antagonists hâve been shown to inhibit tumor metastasis in vivo (see, Maulik et al„ Cytokine & Growth Facta· Reviews, 2002, 13, 41-59). The biological fonctions of c-Met (or c-Met signalling pathway) in normal tissues and human malignandes such as cancer hâve been well documented (Christensen, J.G. et al., Cancer Lett., 2005, 225(1): 1-26; Corso, S. et al., Trends in Mol. Med., 2005, Il (6):284-292).
Tumor growth progression involves the recruitment of new blood vessels into the tumor as well as invasion, adhesion and prolifération of malignant cells. c-Met over expression has been demonstrated on a wide variety of tumor types including breast, colon, rénal, lung, squamous cell myeloid leukemia, hemangiomas, melanomas, astrocytomas, and glioblastomas. Additionally activating mutations in the kinase domain of c-Met hâve been identified in hereditary and sporadic rénal papilloma and squamous cell cardnoma. See Maulik et a! Cytokine & growth Fador reviews 2002,13,41-59; Longati et al Curr Drug Targets 2001,2,4155; Funakoshi et al Clinica Chimica Ada 2003 1-23. Thus modulation of c-Met offers an attractive opportunity to target key oncogenic processes thus limiting cell prolifération, survival and metastasis.
Dysregulated c-Met pathway is linked to tumor formation, growth, maintenance and progression (Birchmeier, C. et al., Nat. Rev. Mol. Cell. Biol. 2003, 4(12):915-925; Boccacdo, C. et al., Nat. Rev. Cancer 2006, 6(8):637-645; Christensen, J.G. et al., Cancer Lett. 2005, 225(1): 1-26). HGF and/or c-Met are over expressed in significant portions of most human cancers, and are often assodated with poor dinical outcomes such as more aggressive disease, disease progression, tumor metastasis and shortened patient survival. Further, patients with high levels of HGF/c-Met proteins are more résistant to chemotherapy and radiotherapy. In addition to abnormal HGF/c-Met expression, the c-Met receptor can also be activated in cancer patients through genetic mutations (both germline and somatic) and gene amplification. Although gene amplification and mutations are the most common genetic alterations that hâve been reported in patients, the receptor can also be activated by délétions, troncations, and gene rearrangement, as well as abnormal receptor processing and defective négative regulatory mechantsms.
The various cancers in which c-Met is implicated indude but are not Iimited to cardnomas (e.g., bladder, breast, cervical, cholangiocardnoma, colorectal, esophageal, gastric, head and neck, kidney, liver, lung, nasopharygeal, ovarian, pancréas, prostate, thyroid); musculoskelétal sarcomas (e.g., osteosarcaoma, synovial sarcoma, rhabdomyosarcoma); soft tissue sarcomas (e.g., MFH/fibrosarcoma, leiomyosarcoma, Kaposi's sarcoma); hematopoietic malignandes (e.g., multiple myeloma, lymphomas, adult T cell leukemia, acute myelogenous leukemia.
chronic myeloid leukemia); and other neoplasms (e.g., glioblastomas, astrocytomas, melanoma, mesothelioma and Wilm's tumor (www.vai.org/met/; Christensen, J.G. et al., Cancer Lett 2005, 225(1): 1-26). c-Met inhibitors may also be usefui ln preventative and adjuvant therapy settings. ln addition, certain cancers (e.g., papillary rénal cell carcinoma, and some gastric and lung cancers) may be treated with c-Met Inhibitors as they are belîeved to be driven by c-Met mutation/genetic alteration and dépendent on c-Met for growth and survtval. These cancers are expected to be sensitive to treatment.
The notion that activated c-Met contributes to tumor formation and progression and could therefore be a potentiai target for effective cancer intervention has been further validated by numerous predinical studies (Birchmeier, C. et al., Nat Rev. Mol. Cell Biol. 2003, 4(12):915925; Christensen, J.G. et al., Cancer Lett. 2005, 225(l): 1-26; Corso, S. et al., Trends in Mol. Med. 2005, 11(6):284- 292). For example, studies hâve demonstrated that the tpr-met fusion gene, over expression of c-Met, and activated c-Met mutations caused oncogenic transformation of various model cell lines and resulted in tumor formation and metastasis in mice. Conversely, significant anti-tumor and anti-metastasïs activities hâve been demonstrated in vitro and in vivo with agents that spedfically impair and/or block HGF/o-Met signalling. Those agents indude anti-HGF and anti-oMet antibodies, HGF peptide antagonists, decoy c-Met receptor, c-Met peptide antagonists, dominant négative c-Met mutations, c-Met spedfic antisense oligonudeotides and ribozymes, and sélective small molécule c-Met kinase inhibitors (Christensen, J.G. et al., Cancer Lett. 2005, 225(1): 1-26). ln addition to its established rôle in cancer, abnormal HGF/c-Met signalling is also implicated in atherosderosis, lung fibrosis, rénal fibrosis and régénération, liver diseases, allergie disorders, inflammatory and autoimmune disorders, cerebrovascular diseases, cardiovascular diseases, and conditions assodated with organ transplantation. See Ma, H. et al., Atherosderosis. 2002,164(l):79-87; Crestani, B. et al., Lab. Invest 2002,82(8): 1015-1022; Sequra-Flores, A.A. et al., Rev. Gastroenterol.

c-Met îs thus an attractive target from a dinical perspective mainly because of its upstream localisation which aids in early détection and timrting metastasis and implications in the growth and métastasés of most types of cancers. These observations suggest that c-Met kinase inhibitors would be an effective treatment for tumors driven by c-Met, and also would prevent disseminated micro métastasés from further progression.
A family of novel compounds hâve been discovered which exhibit c-Met modulating ability and hâve an ameliorating effect against disorders related to abnormal c-Met activity such as Johnson & Johnson’s JNJ-38877605, Amgen’s AMG-458, Eisai’s E-7050 and Pfizer’s PF04217903. However, to date, none of them hâve been used In a clinical study.

More recently Dussault et. al., Anti-Cancer Agents in Médicinal Chemistry, 2009, 9(2), 221-229, hâve provided additional insight about a receptor tyrosine kinase namely, RON (récepteur d’origine nantais) which is dosely related to c-Met. Both c-MET and RON receptors upon activation can induce cell migration, invasion, prolifération and survival. Moreover, both possess oncogenic activity in vitro and in vivo and are often dysregulated in human cancers.
While c-Met is now a well-accepted target for anti-cancer treatment, less is known about the rôle of RON in cancer. Despite their common attributes, c-Met and RON are adivated by different mechanisms in cancer cells. Due to a signifîcant homology between the two RTKs, some small molécule kinase inhibitors of c-Met hâve inhibitory activity on RON suggesting that both receptors might be involved in cancer progression. The review (Dussault et al., supra) discusses the relevance of both c-Met and RON deregulation In human cancers and the progress made In identifying small molécule kinase Inhibitors that can block the activity of these targets in vitro and In animal models. One of the compounds discussed in the review, AMG458, inhibited c-Met and RON with ICsjs of 4 and 9 nM respectively.
Various research groups around the world such as Amgen, Arquel, AstraZeneca, Bristol-Myers
Squibb, Exelixis, Eisai, Incyte, MethylGene, Pfizer, SGX Pharma, SmithKIine Beecham,
Schering, Vertex, Xcovery, Novartis and others hâve been working on targeting either single, dual or multiple kinase targets.

The term stereoisomer refers to compounds, which hâve identical chemical composition, but differ with regard to arrangement of the atoms and the groups in space. These include enantiomers, diastereomers, geometrica! isomers, atropisomer or conformational isomers.
Ail the stereoisomers of compounds described herein are within the scope of this invention. Racemic mixtures are also encompassed within the scope of this invention. Therefore, single stereochemical isomers as well enantiomeric, diastereoîsomeric and géométrie (or conformational) mixtures ofthe présent compounds fall within the scope of the invention.
Certain of the compounds described herein contain one or more asymmetric centers and can thus give rise to enantiomers, diastereomers, and other stereoisomeric forms that can be defined, in terms of absolute stereochemistry, as (R)- or (S)-. The présent chemical entities, pharmaceutical compositions and methods are meant to include ail such possible isomers, including racemic mixtures, optically pure forms and intermediate mixtures. For the instance the non-limiting example of intermediate mixutures include a mixture of isomers in a ratio of 10:90, 13:87, 17:83, 20:80, or 22:78. Optically active (R> and (S)- isomers can be prepared using chiral synthons or chiral reagents, or resolved using conventional techniques. When the compounds described herein contain olefinic double bonds or other centers of géométrie asymmetry, and unless specifîed otherwise, it is intended that the compounds include both E and Z géométrie isomers.
The term tautomers refera to compounds, which are characterized by relatively easy interconversion of isomeric forms in equilibrium. These isomers are intended to be covered by this invention. Tautomers are structurally distinct isomère that interconvert by tautomerization. Tautomerization is a form of isomerization and includes prototropic or proton-shift tautomerization, which is considered a subset of acid-base chemistry. Prototropic tautomerization or proton-shift tautomerization involves the migration of a proton accompanfed by changes in bond order, often the interchange of a single bond with an adjacent double bond. Where tautomerization is possible (e.g. in solution), a chemical equilibrium of tautomers can be reached. An example of tautomerization is keto-enol tautomerization. A spécifie example of keto-enol tautomerization is the interconversion of pentane-2,4-dione and 4hydroxypent-3-en-2-one tautomers. Another example of tautomerization is phenol-keto tautomerization. A spedfic example of phenol-keto tautomerization is the interconversion of pyridin-4-ol and pyridin-4(1H)-one tautomers.
A leaving group or atom is any group or atom that will, under the reaction conditions, deave from the starting material, thus promoting reaction at a specified site. Suitable examples of such groups unless otherwise specified are halogen atoms and mesyloxy, pnitrobenzensulphonyloxy and tosyloxy groups.
The term prodrug refers to a compound, which is an inactive precursor of a compound, converted into its active form in the body by normal metabolic processes. Prodrug design is discussed generally in Hardma, et al. (Eds.), Goodman and Gilman’s The Pharmacological Basis of Therapeutics, 9th ed., pp. 11-16 (1996). A thorough discussion is provided in Higuchi, et al., Prodrugs as Novel Delivery Systems, Vol. 14, ASCD Symposium Sériés, and in Roche (ed.), Bioreversible Carriers in Drug Design, American Pharmaceutical Association and Pergamon Press (1987). To îllustrate, prodrugs can be converted into a pharmacologically active form through hydrolysis of, for example, an ester or amide linkage, thereby introducing or exposing a functional group on the résultant product. The prodrugs can be designed to react with an endogenous compound to form a water-soluble conjugate that further enhances the pharmacological properties of the compound, for example, increased drculatory half-life. Altematively, prodrugs can be designed to undergo covalent modification on a functional group with, for example, glucuronic acid, sulfate, glutathione, amino acids, or acetate. The resulting conjugate can be inactivated and excreted in the urine, or rendered more potent than the parent compound. High molecular weight conjugates also can be excreted into the bile, subjected to enzymatic cleavage, and released back into the circulation, thereby effectîvely increasing the biological half-life of the originally administered compound.
The term ester refers to a compound, which is formed by reaction between an add and an alcohol with élimination of water. An ester can be represented by the general formula RCOOR'. These prodrugs and esters are intended to be covered within the scope of this invention.
Additionally the instant invention also indudes the compounds which differ only in the presence of one or more isotopically enriched atoms for example replacement of hydrogen with deuterium or tritium, or the replacement of a carbon by13C- or 14C-enriched carbon.
The compounds of the présent invention may also contain unnatural proportions of atomic isotopes at one or more of atoms that constitute such compounds.

The relative efficacies of compounds as inhibitors of an enzyme activity (or other biological activity) can be establîshed by determining the concentrations at which each compound inhibits the activity to a predefined extent and then comparing the results. Typically, the preferred détermination is the concentration that inhibits 50% of the activity in a biochemical assay, i.e., the 50% inhibitory concentration or IC50. IC50 déterminations can be accomplished using conventional techniques known in the art In general, an IC50 can be determined by measuring the activity of a given enzyme in the presence of a range of concentrations of the inhibitor under study. The experimentally obtained values of enzyme activity then are plotted against the inhibitor concentrations used. The concentration ofthe inhibitor that shows 50% enzyme activity 56 (as compared to the activity in the absence of any inhibitor) is taken as the IC50 value.
Analogously, other inhibitory concentrations can be defined through appropriate déterminations of activity. For example, in some settings it can be désirable to establish a 90% inhibitory concentration, i.e., IC90, etc.
Accordingly, a c-met sélective inhibitor altematively can be understood to refer to a compound that exhibits a 50% inhibitory concentration (IC50) with respect to c-met kinase, that is at least 10-fold, in another aspect at least 20-fold, and in another aspect at least 30-fold, lower than the IC50 value with respect to any or ail of the other class receptor tyrosine kinase (RTK) family members. In an alternative embodiment of the invention, the term c-met kinase sélective inhibitor can be understood to refer to a compound that exhibits an IC50 with respect to c-met kinase that is at least 50-fold, in another aspect at least 100-fold, in an additional aspect at least 200-fold, and in yet another aspect at least 500-fold, lower than the IC50 with respect to any or ail of the other RTK family members. A c-met kinase sélective inhibitor is typically administered in an amount such that it selectively inhibits c-met activity, as described above.

Also, liposomal or proteinoid encapsulation may be used to formulate the compositions (as, for example, proteinoid microspheres reported in U.S. Pat. No. 4,925,673). Liposomal encapsulation may inciude liposomes that are derivatized with various polymers (e.g., U.S. Pat. No. 5,013,556). The formulation may Indude a compound of the invention and inert ingrédients which protect against dégradation in the stomach and which permit release of the biologically active material in the intestine.
Toxidty and therapeutic efficacy of the met kinase compounds can be determined by standard pharmaceutical procedures in cell cultures or experimental animais, e.g., for determining the
LD50 (the dose léthal to 50% of the population) and the ED50 (the dose therapeutically effective In 50% of the population). Additionally, this information can be determined in cell cultures or experimental animais additionally treated with other thérapies induding but not limited to radiation, chemotherapeutic agents, photodynamic thérapies, radiofrequency ablation, anti-angiogenic agents, and combinations thereof.
The amount ofthe compound administered will be dépendent on the mammal being treated, the severity of the disorder or condition, the rate of administration, the disposition of the compound and the discrétion of the prescribing physician. However, an effective dosage is in the range of about 0.001 to about 100 mg per kg body weight per day, preferably about 1 to about 35 mg/kg/day, in single or divided doses. For a 70 kg human, this would amount to about 0.05 to 7 g/day, preferably about 0.05 to about 2.5 g/day. In some instances, dosage levels below the lower limit of the aforesaid range may be more than adéquate, while in other cases still larger doses may be employed without causing any harmful side effect, e.g. bydividing such larger doses Into several small doses for administration throughout the day.
In some embodiments, a compound of the invention is administered in a single dose.

In practice of the methods of the invention, the pharmaceutical compositions are generally provided in doses ranging from 1 pg compound/kg body weight to 1000 mg/kg, 0.1 mg/kg to 100 mg/kg, 0.1 mg/kg to 50 mg/kg, and 1 to 20 mg/kg, given in daily doses or in équivalent doses at longer or shorter intervals, e.g., every other day, twice weekly, weekly, or twice or three times daily. The Inhibitor compositions may be administered by an initial bolus followed by a continuous infusion to maintain therapeutic circulating levels of drug product. Those of ordinary skîll in the art will readily optimize effective dosages and administration regimens as determined by good medical practice and the dinical condition of the individual to be treated. The frequency of dosing will dépend on the pharmacokinetic parameters of the agents and the route of administration. The optimal pharmaceutical formulation will be determined by one skilled ln the art depending upon the route of administration and desired dosage [see, for example, Remington’s Pharmaceutical Sdences, pp. 1435-1712, the disdosure of which is hereby incorporated by référencé]. Such formulations may influence the physical state, stability, rate of in vivo reiease, and rate of in vivo dearance of the administered agents. Depending on the route of administration, a suitable dose may be calculated according to body weight, body surface area or organ size. Further refinement of the calculations necessary to détermine the appropriate dosage for treatment involving each of the above mentioned formulations is routinely made by those of ordinary skill in the art without undue expérimentation, espedally in light of the dosage information and assays disdosed herein, as well as the pharmacokinetic data observed in human dinical trials. Appropriate dosages may be ascertained by using established assays for determining blood level dosages in conjunction with an appropriate phystdan considering various factors which modify the action of drugs, e.g., the drug's spécifie activity, the severity of the indication, and the responsiveness of the individual, the âge, condition, body weight, sex and diet of the individual, the time of administration and other clinical factors.

MET Kinase Assay Protocol:
Colorimétrie détermination of c-Met Kinase activity
The receptor tyrosine kinase c-Met is a heterodimeric transmembrane glycoprotein involved in several cellular processes that aid in tumor progression. Phosphorylation of the tyrosine residues in the c-Met kinase domain is critical for its activity and the resulting down-stream effects. The colorimétrie assay allows détection of the phosphorylated form of a biotinylated peptide upon activation of human recombinant Met kinase.
MET Kinase Assay Protocol:
c-Met Kinase activity shal! be determined using an HTScan® Met Kinase Assay Kit (Cell Signalling Technology, Beverly, MA) with modifications. Ail incubations are carried out at room température. Briefly, 12.5 pl of a 4X reaction cocktail (DTT/Kinase buffer containing appropriate quantity of human Met kinase) is added to each well of a 96-well plate containing 12.5 μΙ prediluted compound of interest and incubated for 5 minutes. After the initial incubation, 25 μΙ/well of 2X ATP/biotinylated peptide is added and incubated for an additional 30 minutes. The reaction is terminated by the addition of 50 μΙ/well stop buffer (50 mM EDTA, pH 8.0). The reaction mixture (25 μΙ/well) is then transferred to a streptavidin coated plate (Perkin Elmer, Cat# 4009-0010) containing 75 μΙ dH2O and incubated for 60 minutes. The plate is washed with 200 μΙ/well wash buffer (1X PBS, 0.05% Tween-20). After washing, 100 μΙ/well phosphotyrosine mAb (1:1000 in wash buffer containing 1% BSA) is added and incubated for 60 minutes. After another round of washes, 100 μΙ/well europium labelled anti-mouse IgG (1:500 in wash buffer containing 1% BSA) is added and Incubated for an additional 30 minutes. Following additional washes, 100 μΙ/well Delfia<R) enhancement solution (Perkin Elmer, Cat#1244-105) is added and Incubated for 45 minutes. Florescence is measured on a microplate reader (BMG Labtech., Germany) at 340 nm (excitation) and 615 nm (émission) for calculating % inhibition. Data generated can be analyzed further using Graphpad Prism (Graphpad software, San Diego CA) for détermination of IC».
