Description: INDAZOLE COMPOUNDS AND PHARMACEUTICAL COMPOSITIONS FOR INHIBITING PROTEIN KINASES, AND METHODS FOR THEIR USE CROSS-REFERENCE TO RELATED APPLICATION This application claims the benefit of U.S. Provisional Patent Application No. 60/142,130, filed July 2, 1999. FIELD OF THE INVENTION This invention is directed to indazole compounds that mediate and/or inhibit the activity of certain protein kinases, and to pharmaceutical compositions containing such compounds. The invention is also directed to the therapeutic or prophylactic use of such compounds and compositions, and to methods of treating cancer as well as other disease states associated with unwanted angiogenesis and/or cellular proliferation, by administering effective amounts of such compounds. BACKGROUND OF THE INVENTION Protein kinases are a family of enzymes that catalyze phosphorylation of the hydroxyl group of specific tyrosine, serine, or threonine residues in proteins. Typically, such phosphorylation dramatically perturbs the function of the protein, and thus protein kinases are pivotal in the regulation of a wide variety of cellular processes, including metabolisim, cell proliferation, cell differentiation, and cell survival. Of the many different cellular functions in which the activity of protein kinases is known to be required, some processes represent attractive targets for therapeutic intervention for certain disease states. Two examples are angiogenesis and cell-cycle control, in which protein kinases play a pivotal role; these processes are essential for the growth of solid tumors as well as for other diseases. Angiogenesis is the mechanism by which new capillaries are formed from existing vessels. When required, the vascular system has the potential to generate new capillary networks in order to maintain the proper functioning of tissues and organs. In the adult, however, angiogenesis is fairly limited, occurring only in the process of wound healing and neovascularization of the endometrium during menstruation. See Merenmies et al., Cell Growth & Differentiation, 8, 3-10 (1997). On the other hand, unwanted angiogenesis is a hallmark of several diseases, such as retinopathies, psoriasis, rheumatoid arthritis, age-related macular degeneration (AMD), and cancer (solid tumors). Folkman, Nature Med., 1, 27-31 (1995). Protein kinases which have been shown to be involved in the angiogenic process include three members of the growth factor receptor tyrosine kinase family: VEGF-R2 (vascular endothelial growth factor receptor 2, also known as KDR (kinase insert domain receptor) and as FLK-1); FGF-R (fibroblast growth factor receptor); and TEK (also known as Tie-2). VEGF-R2, which is expressed only on endothelial cells, binds the potent angiogenic growth factor VEGF and mediates the subsequent signal transduction through activation of its intracellular kinase activity. Thus, it is expected that direct inhibition of the kinase activity of VEGF-R2 will result in the reduction of angiogenesis even in the presence of exogenous VEGF (see Strawn et al., Cancer Research, 56, 3540-3545 (1996)), as has been shown with mutants of VEGF-R2 which fail to mediate signal transduction. Millauer et al., Cancer Research, 56, 1615-1620 (1996). Furthermore, VEGF-R2 appears to have no function in the adult beyond that of mediating the angiogenic activity of VEGF. Therefore, a selective inhibitor of the kinase activity of VEGF-R2 would be expected to exhibit little toxicity. Similarly, FGF-R binds the angiogenic growth factors aFGF and bFGF and mediates subsequent intracellular signal transduction. Recently, it has been suggested that growth factors such as bFGF may play a critical role in inducing angiogenesis in solid tumors that have reached a certain size. Yoshiji et al., Cancer Research, 57, 3924-3928 (1997). Unlike VEGF-R2, however, FGF-R is expressed in a number of different cell types throughout the body and may or may not play important roles in other normal physiological processes in the adult. Nonetheless, systemic administration of a small-molecule inhibitor of the kinase activity of FGF-R has been reported to block bFGF-induced angiogenesis in mice without apparent toxicity. Mohammad et al., EMBO Journal, 17, 5996-5904 (1998). TEK (also known as Tie-2) is another receptor tyrosine kinase expressed only on endothelial cells which has been shown to play a role in angiogenesis. The binding of the factor angiopoietin-1 results in autophosphorylation of the kinase domain of TEK and results in a signal transduction process which appears to mediate the interaction of endothelial cells with peri-endothelial support cells, thereby facilitating the maturation of newly formed blood vessels. The factor angiopoietin-2, on the other hand, appears to antagonize the action of angiopoietin-1 on TEK and disrupts angiogenesis. Maisonpierre et al., Science, 277, 55-60 (1997). As a result of the above-described developments, it has been proposed to treat angiogenesis by the use of compounds inhibiting the kinase activity of VEGF-R2, FGF-R, and/or TEK. For example, λYTPO International Publication No. WO 97/34876 discloses certain cinnoline derivatives that are inhibitors of VEGF-R2, which may be used for the treatment of disease states associated with abnormal angiogenesis and/or increased vascular permeability such as cancer, diabetes, psoriasis, rheumatoid arthritis, Kaposi's sarcoma, haemangioma, acute and chronic nephropathies, atheroma, arterial restinosis, autoimmune diseases, acute inflammation, and ocular diseases with retinal vessel proliferation. Phosphorylase kinase activates glycogen phosphorylase, thus increasing glycogen breakdown and hepatic glucose release. Hepatic glucose production is disregulated in type 2 diabetes, and is the primary cause of fasting hyperglycemia, which results in many of the secondary complications afflicting these patients. Thus, reduction in glucose release from the liver would lower elevated plasma glucose levels. Inhibitors of phosphorylase kinase should therefore decrease phosphorylase activity and glycogenolysis, thus reducing hyperglycemia in patients. Another physiological response to VEGF is vascular hyperpermeability, which has been proposed to play a role in the early stages of angiogenesis. In ischemic tissues, such as those occurring in the brain of stroke victims, hypoxia trigger VEGF expression, leading to increased vascular permeability and ultimately edema in the surrounding tissues. In a rat model for stroke, it has been shown by van Bruggen et al., J. Clinical Invest, 104, 1613-20 (1999) that administration of a monoclonal antibody to VEGF reduces the infarct volume. Thus, inhibitors of VEGFR are anticipated to be useful for the treatment of stroke. In addition to its role in angiogenesis, protein kinases also play a crucial role in cell-cycle control. Uncontrolled cell proliferation is the insignia of cancer. Cell proliferation in response to various stimuli is manifested by a de-regulation of the cell division cycle, the process by which cells multiply and divide. Tumor cells typically have damage to the genes that directly or indirectly regulate progression through the cell division cycle. Cyclin-dependent kinases (CDKs) are serine-threonine protein kinases that play critical roles in regulating the transitions between different phases of the cell cycle. See, e.g., the articles compiled in Science, 21 A, 1643-1677 (1996). CDK complexes are formed through association of a regulatory cyclin subunit (e.g., cyclin A, Bl, B2, Dl, D2, D3, and E) and a catalytic kinase subunit (e.g., cdc2 (CDK1), CDK2, CDK4, CDK5, and CDK6). As the name implies, the CDKs display an absolute dependence on the cyclin subunit in order to phosphorylate their target substrates, and different kinase/cyclin pairs function to regulate progression through specific phases of the cell cycle. It is CDK4 complexed to the D cyclins that plays a critical part in initiating the cell-division cycle from a resting or quiescent stage to one in which cells become committed to cell division. This progression is subject to a variety of growth regulatory mechanisms, both negative and positive. Aberrations in this control system, particularly those that affect the function of CDK4, have been implicated in the advancement of cells to the highly proliferative state characteristic of malignancies, particularly familial melanomas, esophageal carcinomas, and pancreatic cancers. See, e.g., Kamb, Trends in Genetics, 11, 136-140 (1995); Kamb et al., Science, 264, 436-440 (1994). Myriad publications describe a variety of chemical compounds useful against a variety of therapeutic targets. For example, WIJPO International Publication Nos. WO 99/23077 and WO 99/23076 describe indazole-containing compounds having phosphodiesterase type IV inhibitory activity produced by an indazole-for-catechol bioisostere replacement. U.S. Patent No. 5,760,028 discloses heterocycles including 3-[l-[3-(imidazolin-2-ylamino)propyl]indazol-5- ylcarbonylamino]-2-(benzyloxycarbonylamino)propionic acid, which are useful as antagonists of the α v β 3 integrin and related cell surface adhesive protein receptors. WIPO International Publication No. WO 98/09961 discloses certain indazole derivatives and their use as inhibitors of phosphodiesterase (PDE) type IV or the production of tumor necrosis factor (TNF) in a mammal. Recent additions to the virtual library of known compounds include those described as being anti-proliferative therapeutic agents that inhibit CDKs. For example, U.S. Patent No. 5,621,082 to Xiong et al. discloses nucleic acid encoding an inhibitor of CDK6, and European Patent Publication No. 0 666 270 A2 describes peptides and peptide mimetics that act as inhibitors of CDK1 and CDK2. WLPO International Publication No. WO 97/16447 discloses certain analogs of chromones that are inhibitors of cyclin-dependent kinases, in particular of CDK/cyclin complexes such as CDK4/cyclin Dl, which may be used for inhibiting excessive or abnormal cell proliferation, and therefore for treating cancer. WEPO International Publication No. WO 99/21845 describes 4- aminothiazole derivatives that are useful as CDK inhibitors. There is still a need, however, for small-molecule compounds that may be readily synthesized and are effective in inhibiting one or more CDKs or CDK/cyclin complexes. Because CDK4 may serve as a general activator of cell division in most cells, and complexes of CDK4 and D-type cyclins govern the early Gj. phase of the cell cycle, there is a need for effective inhibitors of CDK4, and D-type cyclin complexes thereof, for treating one or more types of tumors. Also, the pivotal roles of cyclin E/CDK2 and cyclin B/CDK1 kinases in the G/S phase and GflΛ transitions, respectively, offer additional targets for therapeutic intervention in suppressing deregulated cell-cycle progression in cancer. Another protein kinase, CHK1, plays an important role as a checkpoint in cell-cycle progression. Checkpoints are control systems that coordinate cell-cycle progression by influencing the formation, activation and subsequent inactivation of the cyclin-dependent kinases. Checkpoints prevent cell-cycle progression at inappropriate times, maintain the metabolic balance of cells while the cell is arrested, and in some instances can induce apoptosis (programmed cell death) when the requirements of the checkpoint have not been met. See, e.g., O'Connor, Cancer Surveys, 29, 151-182 (1997); Nurse, Cell, 91, 865-867 (1997); Hartwell et al., Science, 266, 1821-1828 (1994); Hartwell et al., Science, 246, 629-634 (1989). One series of checkpoints monitors the integrity of the genome and, upon sensing DNA damage, these "DNA damage checkpoints" block cell-cycle progression in G λ and G 2 phases, and slow progression through S phase. O'Connor, Cancer Surveys, 29, 151-182 (1997); Hartwell et al., Science, 266, 1821-1828 (1994). This action enables DNA repair processes to complete their tasks before replication of the genome and subsequent separation of this genetic material into new daughter cells takes place. Importantly, the most commonly mutated gene in human cancer, the p53 tumor suppressor gene, produces a DNA damage checkpoint protein that blocks cell-cycle progression in G t phase and/or induces apoptosis (programmed cell death) following DNA damage. Hartwell et al., Science, 266, 1821-1828 (1994). The p53 tumor suppressor has also been shown to strengthen the action of a DNA damage checkpoint in G 2 phase of the cell cycle. See, e.g., Bunz et al., Science, 28, 1497-1501 (1998); Winters et al., Oncogene, 17, 673-684 (1998); Thompson, Oncogene, 15, 3025-3035 (1997). Given the pivotal nature of the p53 tumor suppressor pathway in human cancer, therapeutic interventions that exploit vulnerabilities in p53-defective cancer have been actively sought. One emerging vulnerability lies in the operation of the G 2 checkpoint in p53 defective cancer cells. Cancer cells, because they lack G, checkpoint control, are particularly vulnerable to abrogation of the last remaining barrier protecting them from the cancer-killing effects of DNA-damaging agents: the G 2 checkpoint. The G 2 checkpoint is regulated by a control system that has been conserved from yeast to humans. Important in this conserved system is a kinase, CHK1, which transduces signals from the DNA- damage sensory complex to inhibit activation of the cyclin B/Cdc2 kinase, which promotes mitotic entry. See, e.g., Peng et al., Science, 277, 1501-1505 (1997); Sanchez et al., Science, 277, 1497-1501 (1997). Inactivation of CHK1 has been shown to both abrogate G 2 arrest induced by DNA damage inflicted by either anticancer agents or endogenous DNA damage, as well as result in preferential killing of the resulting checkpoint defective cells. See, e.g., Nurse, Cell, 91, 865- 867 (1997); Weinert, Science, 111, 1450-1451 (1997); Walworth et al., Nature, 363, 368-371 (1993); and Al-Khodairy et al., Molec. Biol. Cell, 5, 147-160 (1994). Selective manipulation of checkpoint control in cancer cells could afford broad utilization in cancer chemotherapeutic and radiotherapy regimens and may, in addition, offer a common hallmark of human cancer "genomic instability" to be exploited as the selective basis for the destruction of cancer cells. A number of factors place CHK1 as a pivotal target in DNA-damage checkpoint control. The elucidation of inhibitors of this and functionally related kinases such as Cdsl/CHK2, a kinase recently discovered to cooperate with CHK1 in regulating S phase progression (see Zeng et al., Nature, 395, 507-510 (1998); Matsuoka, Science, 282, 1893-1897 (1998)), could provide valuable new therapeutic entities for the treatment of cancer. Integrin receptor binding to ECM initiates intracellular signals mediated by FAK (Focal Adhesion Kinase) that are involved in cell motility, cellular proliferation, and survival. In human cancers, FAK overexpression is implicated in tumorigenesis and metastatic potential through its role in integrin mediated signaling pathways. Tyrosine kinases can be of the receptor type (having extracellular, transmembrane and intracellular domains) or the non-receptor type (being wholly intracellular). At least one of the non-receptor protein tyrosine kinases, namely, LCK, is believed to mediate the transduction in T-cells of a signal from the interaction of a cell-surface protein (Cd4) with a cross-linked anti-Cd4 antibody. A more detailed discussion of non-receptor tyrosine kinases is provided in Bolen, Oncogene, 8, 2025-2031 (1993), which is incorporated herein by reference. In addition to the protein kinases identified above, many other protein kinases have been considered to be therapeutic targets, and numerous publications disclose inhibitors of kinase activity, as reviewed in the following: McMahon et al, Oncologist, 5, 3-10 (2000); Holash et al., Oncogene, 18, 5356-62 (1999); Thomas et al., J. Biol. Chem., 214, 36684-92 (1999); Cohen, Curr. Op. Chem. Biol, 3, 459-65 (1999); Klohs et al., Curr. Op. Chem. Biol., 10, 544-49 (1999); McMahon et al., Current Opinion in Drug Discovery & Development, 1, 131-146 (1998); Strawn et al., Exp. Opin. Invest. Drugs, 7, 553-573 (1998). WD?O International Publication WO 00/18761 discloses certain substituted 3- cyanoquinolines as protein kinase inhibitors. There is still a need, however, for effective inhibitors of protein kinases. Moreover, as is understood by those skilled in the art, it is desirable for kinase inhibitors to possess both high affinity for the target kinase or kinases as well as high selectivity versus other protein kinases. SUMMARY OF THE INVENTION Thus, an objective of the invention is to discover potent inhibitors of protein kinases. Another objective of the invention is to discover effective kinase inhibitors having a strong and selective affinity for one or more particular kinases.

The term "alkenyl" refers to straight- and branched-chain alkenyl groups having from two to twelve carbon atoms. Illustrative alkenyl groups include prop-2- enyl, but-2-enyl, but-3-enyl, 2-methylprop-2-enyl, hex-2-enyl, and the like. The term "alkynyl" refers to straight- and branched-chain alkynyl groups having from two to twelve carbon atoms. The term "cycloalkyl" refers to saturated or partially unsaturated carbocycles having from three to twelve carbon atoms, including bicyclic and tricyclic cycloalkyl structures. Suitable cycloalkyls include cyclopropyl, cyclobutyl, cyclopentyl, cyclohexyl, cycloheptyl, and the like. A "heterocycloalkyl" group is intended to mean a saturated or partially unsaturated monocyclic radical containing carbon atoms, preferably 4 or 5 ring carbon atoms, and at least one heteroatom selected from nitrogen, oxygen and sulfur. The terms "aryl" and "heteroaryl" refer to monocyclic and polycyclic unsaturated or aromatic ring structures, with "aryl" referring to those that are carbocycles and "heteroaryl" referring to those that are heterocycles. Examples of aromatic ring structures include phenyl, naphthyl, 1,2,3,4-tetrahydronaphthyl, furyl, thienyl, pyrrolyl, pyridinyl, pyrazolyl, imidazolyl, pyrazinyl, pyridazinyl, 1,2,3- triazinyl, 1 ,2,4-oxadiazolyl, 1,3,4-oxadiazolyl, l-H-tetrazol-5-yl, indolyl, quinolinyl, benzofuranyl, benzothiophenyl (thianaphthenyl), and the like.

The terms "comprising" and "including" are used in an open, non-limiting sense. It is understood that while a compound of Formula I may exhibit the phenomenon of tautomerism, the formula drawings within this specification expressly depict only one of the possible tautomeric forms. It is therefore to be understood that within the invention the formulae are intended to represent any tautomeric form of the depicted compound and is not to be limited merely to a specific tautomeric form depicted by the formula drawings. Some of the inventive compounds may exist as single stereoisomers (i.e., essentially free of other stereoisomers), racemates, and/or mixtures of enantiomers and/or diastereomers. All such single stereoisomers, racemates and mixtures thereof are intended to be within the scope of the present invention. Preferably, the inventive compounds that are optically active are used in optically pure form. As generally understood by those skilled in the art, an optically pure compound having one chiral center is one that consists essentially of one of the two possible enantiomers (i.e., is enantiomerically pure), and an optically pure compound having more than one chiral center is one that is both diastereomerically pure and enantiomerically pure. Preferably, the compounds of the present invention are used in a form that is at least 90% optically pure, that is , a form that contains at least 90% of a single isomer (80% enantiomeric excess ("e.e.") or diastereomeric excess ("d.e.")), more preferably at least 95% (90% e.e. or d.e.), even more preferably at least 97.5% (95% e.e. or d.e.), and most preferably at least 99% (98% e.e. or d.e.). Additionally, the formulas are intended to cover solvated as well as unsolvated forms of the identified structures. For example, Formula I includes compounds of the indicated structure in both hydrated and non-hydrated forms. Other examples of solvates include the structures in combination with isopropanol, ethanol, methanol, DMSO, ethyl acetate, acetic acid, or ethanolamine. In addition to compounds of the Formula I, π, HI, and IV, the invention includes pharmaceutically acceptable prodrugs, pharmaceutically active metabolites, and pharmaceutically acceptable salts of such compounds. "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. "A pharmaceutically active metabolite" is intended to mean a pharmacologically active product produced through metabolism in the body of a specified compound or salt thereof. Metabolites of a compound may be identified using routine techniques known in the art and their activities determined using tests such as those described herein. Prodrugs and active metabolites of a compound may be identified using routine techniques known in the art. See, e.g., Bertolini, G. et al., J. Med. Chem., 40, 2011-2016 (1997); Shan, D. et al., J. Pharm. Set, 86 (7), 765-767; Bagshawe K., Drug Dev. Res., 34, 220-230 (1995); Bodor, N., Advances in Drug Res., 13, 224-331 (1984); Bundgaard, H, Design of Prodrugs (Elsevier Press 1985); and Larsen, I. K., Design and Application of Prodrugs, Drug Design and Development (Krogsgaard- Larsen et al., eds., Harwood Academic Publishers, 1991). "A pharmaceutically acceptable salt" is intended to mean a salt that retains the biological effectiveness of the free acids and bases of the specified compound and that is 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, and inorganic and organic acids, to form a pharmaceutically acceptable salt. Exemplary 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 as 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, butyne-1,4- dioates, hexyne-l,6-dioates, benzoates, chlorobenzoates, methylbenzoates, dinitrobenzoates, hydroxybenzoates, methoxybenzoates, phthalates, sulfonates, xylenesulfonates, phenylacetates, phenylpropionates, phenylbutyrates, citrates, lactates, γ-hydroxybutyrates, glycollates, tartrates, methane-sulfonates, propanesulfonates, naphthalene- 1 -sulfonates, naphthalene-2-sulfonates, and mandelates. 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 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 Uke. 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, such as an amine (primary, secondary or tertiary), an alkali metal hydroxide or alkaline earth metal hydroxide, or the like. Illustrative examples of suitable salts include organic salts derived from amino acids, such as glycine and arginine, ammonia, primary, secondary, and tertiary amines, and cyclic amines, such as piperidine, morpholine and piperazine, and inorganic salts derived from sodium, calcium, potassium, magnesium, manganese, iron, copper, zinc, aluminum and lithium. In the case of agents that are solids, it is understood by those skilled in the art that the inventive compounds and salts may exist in different crystal or polymorphic forms, all of which are intended to be within the scope of the present invention and specified formulas. Therapeutically effective amounts of the agents of the invention may be used to treat diseases mediated by modulation or regulation of protein kinases. An "effective amount" is intended to mean that amount of an agent 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 protein kinases, such as tryosine kinases. Thus, e.g., a therapeutically effective amount of a compound of the Formula I, salt, active metabolite or prodrug thereof is a quantity sufficient to modulate, regulate, or inhibit the activity of one or more protein kinases such that a disease condition which is mediated by that activity is reduced or alleviated. The amount of a given agent that will correspond to such an amount will vary depending upon factors such as the particular compound, disease condition and its severity, the identity (e.g., weight) of the mammal in need of treatment, but can nevertheless be routinely determined by one skilled in the art. "Treating" is intended to mean at least the mitigation of a disease condition in a mammal, such as a human, that is affected, at least in part, by the activity of one or more protein kinases, such as tyrosine kinases, and includes: preventing the disease condition from occurring in a mammal, particularly when the mammal is found to be predisposed to having the disease condition but has not yet been diagnosed as having it; modulating and or inhibiting the disease condition; and/or alleviating the disease condition. The inventive agents may be prepared using the reaction routes and synthesis schemes as described below, employing the techniques available in the art using starting materials that are readily available. In one general synthetic process, compounds of Formula I are prepared according to the following reaction scheme: R 1 -M ons 6-Nitroindazole (compound V) is treated with iodine and base, e.g., NaOH, in an aqueous/organic mixture, preferably with dioxane. The mixture is acidified and the product isolated by filtration. To the resulting 3-iodo-6- nitroindazole in dichloromethane-50% aqueous KOH at 0 °C is added a protecting group ("Pg") reagent (wherein X = halo), preferably trimethylsilylethoxymethyl chloride (SEM-C1), and a phase transfer catalyst, e.g., tetrabutylammonium bromide (TBABr). After 1-4 hours, the two phases are diluted, the organics are separated, dried with sodium sulfate, filtered and concentrated. The crude product is purified by silica gel chromatography to give compounds of formula VI. Treatment of compounds of formula VI in a suitable organic solvent with a suitable R'-organometallic reagent, preferably an R 1 - boronic acid, in the presence of aqueous base, e.g., sodium carbonate, and a suitable catalyst, preferably Pd(PPh 3 ) 4 gives, after extractive work-up and silica gel chromatography, compounds of formula VII. The R 1 substituent may be exchanged within compounds of formula VII or later intermediates throughout this scheme by oxidative cleavage (e.g., ozonolysis) followed by additions to the resulting aldehyde functionality with Wittig or condensation transformations (typified in Example 42(a-e)). Treatment of compounds of formula VII with a reducing agent, preferably SnCl 2 , provides, after conventional aqueous work up and purification, compounds of formula VIII. For the series of derivatives where Y = NH or N-lower alkyl, compounds of formula VIII may be treated with aryl or heteroaryl chlorides, bromides, iodides or triflates in the presence of a base, preferably Cs 2 CO 3 , and catalyst, preferably Pd-BLNAP, (and where Y = N-lower alkyl, with a subsequent alkylation step) to provide compounds of formula X. To produce other Y linkages, sodium nitrite is added to compounds of formula VIII under chilled standard aqueous acidic conditions followed by the addition of potassium iodide and gentle warming. Standard work-up and purification produces iodide compounds of formula IX. Treatment of compounds of formula LX with an organometallic reagent, e.g., butyllithium, promotes lithium halogen exchange. This intermediate is then reacted with an R 2 electrophile, e.g., a carbonyl or triflate, through the possible mediation of additional metals and catalysts, preferably zinc chloride and Pd(PPh 3 ) 4 to provide compounds of formula X. Alternatively, compounds of formula LX may be treated with an organometallic reagent such as an organoboronic acid in the presence of a catalyst, e.g., Pd(PPh 3 ) 4 , under a carbon monoxide atmosphere to give compounds of formula X. Alternatively, for derivatives where Y = NH or S, compounds of formula IX may be treated with appropriate amines or thiols in the presence of base, preferably Cs 2 CO 3 or K O 4 and a catalyst, preferably Pd-BINAP or Pd-(bis- cyclohexyl)biphenylphosphine to provide compounds of formula X. Conventional functional group interchanges, such as oxidations, reductions, alkylations, acylations, condensations, and deprotections may then be employed to further derivatize this series giving final compounds of Formula I. The inventive compounds of Formula I may also be prepared according general procedure shown in the following scheme: xπi 6-Iodoindazole (XI) is treated with iodine and base, e.g., NaOH, in an aqueous/organic mixture, preferably with dioxane. The mixture is acidified and the product XII is isolated by filtration. To the resulting 3,6 di-iodoindazole in dichloromethane-50% aqueous KOH at 0 °C is added a protecting group reagent, preferably SEM-C1, and a phase transfer catalyst, e.g., TBABr. The two phases are diluted, the organics separated, dried with sodium sulfate, filtered and concentrated. The crude product is purified by silica gel chromatography to give compounds of the formula XIH. Treatment of compounds of formula Xiπ in a suitable organic solvent with a suitable R 2 -organometallic reagent, e.g., R 2 -ZnCl or boron R 2 -boron reagent and a suitable catalyst, preferably Pd(PPh 3 ) 4 gives, after extractive work-up and silica gel chromatography, compounds of formula XIV. Treatment of compounds of formula XIV in a suitable organic solvent with a suitable R l -organometallic reagent (e.g., boron R'-boron reagent or R'-ZnCl), in the presence of aqueous base, sodium carbonate, and a suitable catalyst, preferably Pd(PPh 3 ) 4 gives, after extractive work-up and silica gel chromatography, compounds of formula XV. Conventional functional group interchanges, such as oxidations, reductions, alkylations, acylations, condensations and deprotections may then be employed to further derivatize this series giving final compounds of Formula I. Alternatively, compounds of Formula I where R 2 is a substituted or unsubstituted Y-Ar, where Y is O or S may be prepared according to the following general scheme: XVI xv M-B, XCO-R 1 catalyst, heat or DDQ modifications A stirred acetone solution of 3-chloro-cyclohex-2-enone (XV), H-R 2 , and anhydrous potassium carbonate is refluxed for 15-24 hours, cooled, and filtered. Concentrating and chromatographing the filtrate on silica gel gives 3-R 2 - cyclohex-2-enone (XVI). The ketones of formula XVI may be reacted with a suitable base (M-B), preferably lithium bis(trimethylsily)amide, and reacted with R'-CO-X (where X = halogen), which after standard acid work up and purification provides compounds of the formula XVII. This product, in HOAc/EtOH, combined with hydrazine monohydrate, is heated at a suitable temperature for an appropriate time period, preferably at 60-80 °C for 2-4 hours. After cooling, the mixture is poured into saturated sodium bicarbonate solution, extracted with an organic solvent, concentrated, and purified on silica gel to give compounds of formula XVIII. Compounds of formula XVIII may be oxidized using a variety of known methods to give compounds of the Formula I. Other compounds of Formula I may be prepared in manners analogous to the general procedures described above or the detailed procedures described in the examples herein. The affinity of the compounds of the invention for a receptor may be enhanced by providing multiple copies of the ligand in close proximity, preferably using a scaffolding provided by a carrier moiety. It has been shown that provision of such multiple valence compounds with optimal spacing between the moieties dramatically improves binding to a receptor. See, e.g., Lee et al., Biochem, 23, 4255 (1984). The multivalency and spacing can be controlled by selection of a suitable carrier moiety or linker units. Such moieties include molecular supports which contain a multiplicity of functional groups that can be reacted with functional groups associated with the compounds of the invention. Of course, a variety of carriers can be used, including proteins such as BSA or HAS, a multiplicity of peptides including, for example, pentapeptides, decapeptides, pentadecapeptides, and the like. The peptides or proteins can contain the desired number of amino acid residues having free amino groups in their side chains; however, other functional groups, such as sulfhydryl groups or hydroxyl groups, can also be used to obtain stable linkages. Compounds that potently regulate, modulate, or inhibit the protein kinase activity associated with receptors VEGF, FGF, CDK complexes, TEK, CHK1, LCK, FAK, and phosphorylase kinase among others, and which inhibit angiogenesis and/or cellular profileration is desirable and is.one preferred embodiment of the present invention. The present invention is further directed to methods of modulating or inhibiting protein kinase activity, for example in mammalian tissue, by administering an inventive agent. The activity of the inventive compounds as modulators of protein kinase activity, such as the activity of kinases, may be measured by any of the methods available to those skilled in the art, including in vivo and/or in vitro assays. Examples of suitable assays for activity measurements include those described in Parast C. et al., Biochemistry, 37, 16788-16801 (1998); Jeffrey et al., Nature, 376, 313-320 (1995); WTPO International Publication No. WO 97/34876; and WIPO International Publication No. WO 96/14843. These properties may be assessed, for example, by using one or more of the biological testing procedures set out in the examples below. The active agents of the invention may be formulated into pharmaceutical compositions as described below. Pharmaceutical compositions of this invention comprise an effective modulating, regulating, or inhibiting amount of a compound of Formula I, π, HI, or IV and an inert, pharmaceutically acceptable carrier or diluent. In one embodiment of the pharmaceutical compositions, efficacious levels of the inventive agents are provided so as to provide therapeutic benefits involving modulation of protein kinases. By "efficacious levels" is meant levels in which the effects of protein kinases are, at a minimum, regulated. These compositions are prepared in unit-dosage form appropriate for the mode of administration, e.g., parenteral or oral administration. An inventive agent is administered in conventional dosage form prepared by combining a therapeutically effective amount of an agent (e.g., a compound of Formula I) as an active ingredient with appropriate pharmaceutical carriers or diluents according to conventional procedures. These procedures may involve mixing, granulating and compressing or dissolving the ingredients as appropriate to the desired preparation. The pharmaceutical carrier employed may be either a solid or liquid. Exemplary of solid carriers are lactose, sucrose, talc, gelatin, agar, pectin, acacia, magnesium stearate, stearic acid and the like. Exemplary of liquid carriers are syrup, peanut oil, olive oil, water and the like. Similarly, the carrier or diluent may include time-delay or time-release material known in the art, such as glyceryl monostearate or glyceryl distearate alone or with a wax, ethylcellulose, hydroxypropylmethylcellulose, methylmethacrylate and the like. A variety of pharmaceutical forms can be employed. Thus, if a solid carrier is used, the preparation can be tableted, placed in a hard gelatin capsule in powder or pellet form or in the form of a troche or lozenge. The amount of solid carrier may vary, but generally will be from about 25 mg to about 1 g. If a liquid carrier is used, the preparation will be in the form of syrup, emulsion, soft gelatin capsule, sterile injectable solution or suspension in an ampoule or vial or non-aqueous liquid suspension. To obtain a stable water-soluble dose form, a pharmaceutically acceptable salt of an inventive agent is dissolved in an aqueous solution of an organic or inorganic acid, such as 0.3M solution of succinic acid or citric acid. If a soluble salt form is not available, the agent may be dissolved in a suitable cosolvent or combinations of cosolvents. Examples of suitable cosolvents include, but are not limited to, alcohol, propylene glycol, polyethylene glycol 300, polysorbate 80, gylcerin and the like in concentrations ranging from 0-60% of the total volume. In an exemplary embodiment, a compound of Formula I is dissolved in DMSO and diluted with water. The composition may also be in the form of a solution of a salt form of the active ingredient in an appropriate aqueous vehicle such as water or isotonic saline or dextrose solution. It will be appreciated that the actual dosages of the agents used in the compositions of this invention will vary according to the particular complex being used, the particular composition formulated, the mode of administration and the particular site, host and disease being treated. Optimal dosages for a given set of conditions can be ascertained by those skilled in the art using conventional dosage- determination tests in view of the experimental data for an agent. For oral administration, an exemplary daily dose generally employed is from about 0.001 to about 1000 mg/kg of body weight, more preferably from about 0.001 to about 50 mg/kg body weight, with courses of treatment repeated at appropriate intervals. Administration of prodrugs are typically dosed at weight levels which are chemically equivalent to the weight levels of the fully active form. The compositions of the invention may be manufactured in manners generally known for preparing pharmaceutical compositions, e.g., using conventional techniques such as mixing, dissolving, granulating, dragee-making, levigating, emulsifying, encapsulating, entrapping or lyophilizing. Pharmaceutical compositions may be formulated in a conventional manner using one or more physiologically acceptable carriers, which may be selected from excipients and auxiliaries that facilitate processing of the active compounds into preparations which can be used pharmaceutically. Proper formulation is dependent upon the route of administration chosen. For injection, the agents of the invention may be formulated into aqueous solutions, preferably in physiologically compatible buffers such as Hanks's solution, Ringer's solution, or physiological saline buffer. For transmucosal administration, penetrants appropriate to the barrier to be permeated are used in the formulation. Such penetrants are generally known in the art. For oral administration, the compounds can be formulated readily by combining the active compounds with pharmaceutically acceptable carriers known in the art. Such carriers enable the compounds of the invention to be formulated as tablets, pills, dragees, capsules, liquids, gels, syrups, slurries, suspensions and the like, for oral ingestion by a patient to be treated. Pharmaceutical preparations for oral use can be obtained using a solid excipient in admixture with the active ingredient (agent), optionally grinding the resulting mixture, and processing the mixture of granules after adding suitable auxiliaries, if desired, to obtain tablets or dragee cores. Suitable excipients include: fillers such as sugars, including lactose, sucrose, mannitol, or sorbitol; and cellulose preparations, for example, maize starch, wheat starch, rice starch, potato starch, gelatin, gum, methyl cellulose, hydroxypropylmethyl-cellulose, sodium carboxymethylcellulose, or polyvinylpyrrolidone (PVP). If desired, disintegrating agents may be added, such as crosslinked polyvinyl pyrrolidone, agar, or alginic acid or a salt thereof such as sodium alginate. Dragee cores are provided with suitable coatings. For this purpose, concentrated sugar solutions may be used, which may optionally contain gum arabic, polyvinyl pyrrolidone, Carbopol gel, polyethylene glycol, and/or titanium lacquer solutions, and suitable organic solvents or solvent mixtures. Dyestuffs or pigments may be added to the tablets or dragee coatings for identification or to characterize different combinations of active agents. Pharmaceutical preparations which can be used orally include push-fit capsules made of gelatin, as well as soft, sealed capsules made of gelatin and a plasticizer, such as glycerol or sorbitol. The push-fit capsules can contain the active ingredients in admixture with fillers such as lactose, binders such as starches, and/or lubricants such as talc or magnesium stearate, and, optionally, stabilizers. In soft capsules, the active agents may be dissolved or suspended in suitable liquids, such as fatty oils, liquid paraffin, or liquid polyethylene glycols. In addition, stabilizers may be added. All formulations for oral administration should be in dosages suitable for such administration. For buccal administration, the compositions may take the form of tablets or lozenges formulated in conventional manner. For administration intranasally or by inhalation, the compounds for use according to the present invention are conveniently delivered in the form of an aerosol spray presentation from pressurized packs or a nebuliser, with the use of a suitable propellant, e.g., dichlorodifluoromethane, trichlorofluoromethane, dichlorotetrafluoroethane, carbon dioxide or other suitable gas. In the case of a pressurized aerosol the dosage unit may be determined by providing a valve to deliver a metered amount. Capsules and cartridges of gelatin for use in an inhaler or insufflator and the like may be formulated containing a powder mix of the compound and a suitable powder base such as lactose or starch. The compounds may be formulated for parenteral administration by injection, e.g., by bolus injection or continuous infusion. Formulations for injection may be presented in unit-dosage form, e.g., in ampoules or in multi-dose containers, with an added preservative. The compositions may take such forms as suspensions, solutions or emulsions in oily or aqueous vehicles, and may contain formulatory agents such as suspending, stabilizing and/or dispersing agents. Pharmaceutical formulations for parenteral administration include aqueous solutions of the active compounds in water-soluble form. Additionally, suspensions of the active agents may be prepared as appropriate oily injection suspensions. Suitable lipophilic solvents or vehicles include fatty oils such as sesame oil, or synthetic fatty acid esters, such as ethyl oleate or triglycerides, or liposomes. Aqueous injection suspensions may contain substances which increase the viscosity of the suspension, such as sodium carboxymethyl cellulose, sorbitol, or dextran. Optionally, the suspension may also contain suitable stabilizers or agents which increase the solubility of the compounds to allow for the preparation of highly concentrated solutions. For administration to the eye, a compound of the Formula I, II, HI, or IV is delivered in a pharmaceutically acceptable ophthalmic vehicle such that the compound is maintained in contact with the ocular surface for a sufficient time period to allow the compound to penetrate the corneal and internal regions of the eye, including, for example, the anterior chamber, posterior chamber, vitreous body, aqueous humor, vitreous humor, cornea, iris/cilary, lens, choroid/retina and selera. The pharmaceutically acceptable ophthalmic vehicle may be an ointment, vegetable oil, or an encapsulating material. A compound of the invention may also be injected directly into the vitreous and aqueous humor. Alternatively, the active ingredient may be in powder form for constitution with a suitable vehicle, e.g., sterile pyrogen-free water, before use. The compounds may also be formulated in rectal compositions such as suppositories or retention enemas, e.g, containing conventional suppository bases such as cocoa butter or other glycerides. In addition to the formulations described above, the compounds may also be formulated as a depot preparation. Such long-acting formulations may be administered by implantation (for example, subcutaneously or intramuscularly) or by intramuscular injection. Thus, for example, the compounds may be formulated with suitable polymeric or hydrophobic materials (for example, as an emulsion in an acceptable oil) or ion-exchange resins, or as sparingly soluble derivatives, for example, as a sparingly soluble salt. A pharmaceutical carrier for hydrophobic compounds is a cosolvent system comprising benzyl alcohol, a nonpolar surfactant, a water-miscible organic polymer, and an aqueous phase. The cosolvent system may be a VPD co-solvent system. VPD is a solution of 3% w/v benzyl alcohol, 8% w/v of the nonpolar surfactant polysorbate 80, and 65% w/v polyethylene glycol 300, made up to volume in absolute ethanol. The VPD co-solvent system (VPD:5W) contains VPD diluted 1:1 with a 5% dextrose in water solution. This co-solvent system dissolves hydrophobic compounds well, and itself produces low toxicity upon systemic administration. Naturally, the proportions of a co-solvent system may be varied considerably without destroying its solubility and toxicity characteristics. Furthermore, the identity of the co-solvent components may be varied: for example, other low-toxicity nonpolar surfactants may be used instead of polysorbate 80; the fraction size of polyethylene glycol may be varied; other biocompatible polymers may replace polyethylene glycol, e.g. polyvinyl pyrrolidone; and other sugars or polysaccharides may be substituted for dextrose. Alternatively, other delivery systems for hydrophobic pharmaceutical compounds may be employed. Liposomes and emulsions are known examples of delivery vehicles or carriers for hydrophobic drugs. Certain organic solvents such as dimethylsulfoxide also may be employed, although usually at the cost of greater toxicity. Additionally, the compounds may be delivered using a sustained-release system, such as semipermeable matrices of solid hydrophobic polymers containing the therapeutic agent. Various sustained-release materials have been established and are known by those skilled in the art. Sustained-release capsules may, depending on their chemical nature, release the compounds for a few weeks up to over 100 days. Depending on the chemical nature and the biological stability of the therapeutic reagent, additional strategies for protein stabilization may be employed. The pharmaceutical compositions also may comprise suitable solid- or gel- phase carriers or excipients. Examples of such carriers or excipients include calcium carbonate, calcium phosphate, sugars, starches, cellulose derivatives, gelatin, and polymers such as polyethylene glycols. Some of the compounds of the invention may be provided as salts with pharmaceutically compatible counter ions. Pharmaceutically compatible salts may be formed with many acids, including hydrochloric, sulfuric, acetic, lactic, tartaric, malic, succinic, etc. Salts tend to be more soluble in aqueous or other protonic solvents than are the corresponding free-base forms. The preparation of preferred compounds of the present invention is described in detail in the following examples, but the artisan will recognize that the chemical reactions described may be readily adapted to prepare a number of other protein kinase inhibitors of the invention. For example, the synthesis of non-exemplified compounds according to the invention may be successfully performed by modifications apparent to those skilled in the art, e.g., by appropriately protecting interfering groups, by changing to other suitable reagents known in the art, or by making routine modifications of reaction conditions. Alternatively, other reactions disclosed herein or known in the art will be recognized as having applicability for preparing other compounds of the invention. EXAMPLES In the examples described below, unless otherwise indicated all temperatures are set forth in degrees Celsius and all parts and percentages are by weight. Reagents were purchased from commercial suppliers such as Aldrich Chemical Company or Lancaster Synthesis Ltd. and were used without further purification unless otherwise indicated. Tetrahydrofuran (THF), N,N-dimethylformamide (DMF), dichloromethane, toluene, and dioxane were purchased from Aldrich in Sure seal bottles and used as received. All solvents were purified using standard methods readily known to those skilled in the art, unless otherwise indicated. The reactions set forth below were done generally under a positive pressure of argon or nitrogen or with a drying tube, at ambient temperature (unless otherwise stated), in anhydrous solvents, and the reaction flasks were fitted with rubber septa for the introduction of substrates and reagents via syringe. Glassware was oven dried and/or heat dried. Analytical thin layer chromatography (TLC) was performed on glass-backed silica gel 60 F 254 plates Analtech (0.25 mm) and eluted with the appropriate solvent ratios (v/v), and are denoted where appropriate. The reactions were assayed by TLC and terminated as judged by the consumption of starting material. Visualization of the TLC plates was done with a p-anisaldehyde spray reagent or phosphomolybdic acid reagent (Aldrich Chemical 20 wt % in ethanol) and activated with heat. Work-ups were typically done by doubling the reaction volume with the reaction solvent or extraction solvent and then washing with the indicated aqueous solutions using 25% by volume of the extraction volume unless otherwise indicated. Product solutions were dried over anhydrous Na 2 SO prior to filtration and evaporation of the solvents under reduced pressure on a rotary evaporator and noted as solvents removed in vacuo. Flash column chromatography (Still et al., J. Org. Chem., 43, 2923 (1978)) was done using Baker grade flash silica gel (47-61 μm) and a silica gel: crude material ratio of about 20:1 to 50:1 unless otherwise stated. Hydrogenolysis was done at the pressure indicated in the examples or at ambient pressure. 1H-NMR spectra were recorded on a Bruker instrument operating at 300 MHz and I3 C-NMR spectra were recorded operating at 75 MHz. NMR spectra were obtained as CDC1 3 solutions (reported in ppm), using chloroform as the reference standard (7.25 ppm and 77.00 ppm) or CD 3 OD (3.4 and 4.8 ppm and 49.3 ppm), or internally tetramethylsilane (0.00 ppm) when appropriate. Other NMR solvents were used as needed. When peak multiplicities are reported, the following abbreviations are used: s (singlet), d (doublet), t (triplet), m (multiplet), br (broadened), dd (doublet of doublets), dt (doublet of triplets). Coupling constants, when given, are reported in Hertz (Hz). Infrared (IR) spectra were recorded on a Perkin-Elmer FT-IR Spectrometer as neat oils, as KBr pellets, or as CDC1 3 solutions, and when given are reported in wave numbers (cm 1 ). The mass spectra were obtained using LS S or electiospray. All melting points (mp) are uncorrected. Example 1(a): 3-[E-2-(3,4-Dimethoxy-phenyl)vinyl]-6-(3-methoxy-4-hydroxy- phenyl)-lH-indazole The 3-[E/Z-2-(3,4-dimethoxy-phenyl)vinyl]-6-[3-methoxy-4- (methoxymethoxy)phenyl]-lH-indazole (-205 mg, 0.461 mmol (theoretical)) was dissolved in tetrahydrofuran (THF, 10 mL) and was treated with water (10 mL) and trifluoroacetic acid (TFA, 20 mL). The reaction mixture was allowed to stir at 23 °C for 30 minutes (min.). The mixture was diluted with toluene (100 mL) and the volatile materials were removed under reduced pressure (30 mm Hg, 35 °C) to give a concentrated volume of - 5 mL. Again, toluene (100 mL) was added and the mixture was concentrated under reduced pressure to give crude material which still contained some acid. The material was partitioned between ethyl acetate and saturated sodium bicarbonate, the organic material was separated, dried over sodium sulfate, decanted, and concentrated under reduced pressure. The residue, a mixture of olefin isomers, (-185 mg, 0.461 mmol (theoretical)) was taken up in dichloromethane (50 mL) at 23 °C and was treated with iodine (80 mg).

The exemplary compounds described above may be tested for their activity using the tests described below. BIOLOGICAL TESTING: ENZYME ASSAYS The stimulation of cell proliferation by growth factors such as VEFG, FGF, and others is dependent upon their induction of autophosphorylation of each of their respective receptor's tyrosine kinases. Therefore, the ability of a protein kinase inhibitor to block autophosphorylation can be measured by inhibition of the peptide substrates. To measure the protein kinase inhibition activity of the compounds, the following constructs were devised. VEGF-R2 Construct for Assay: This construct determines the ability of a test compound to inhibit tyrosine kinase activity. A construct (VEGF-R2Δ50) of the cytosolic domain of human vascular endothelial growth factor receptor 2 (VEGF-R2) lacking the 50 central residues of the 68 residues of the kinase insert domain was expressed in a baculovirus/insect cell system. Of the 1356 residues of full-length VEGF-R2, VEGF-R2Δ50 contains residues 806-939 and 990-1171, and also one point mutation (E990V) within the kinase insert domain relative to wild-type VEGF- R2. Autophosphorylation of the purified construct was performed by incubation of the enzyme at a concentration of 4 μM in the presence of 3 mM ATP and 40 mM MgCl 2 in 100 mM HEPES, pH 7.5, containing 5% glycerol and 5 mM DTT, at 4 °C for 2 h. After autophosphorylation, this construct has been shown to possess catalytic activity essentially equivalent to the wild-type autophosphorylated kinase domain construct. See Parast et al., Biochemistry, 37, 16788-16801 (1998). FGF-R 1 Construct for Assay: The intracellular kinase domain of human FGF- Rl was expressed using the baculovirus vector expression system starting from the endogenous methionine residue 456 to glutamate 766, according to the residue numbering system of Mohammadi et al., Mol. Cell. Biol., 16, 977-989 (1996). In addition, the construct also has the following 3 amino acid substitutions: L457V, C488A, and C584S. LCK Construct for Assay: The LCK tyrosine kinase was expressed in insect cells as an N-terminal deletion starting from amino acid residue 223 to the end of the protein at residue 509, with the following two amino acid substitutions at the N- terminus: P233M and C224D. CHKl Construct for Assay: C-terminally His-tagged full-length human CHKl (FL-CHKl) was expressed using the baculovirus/insect cell system. It contains 6 histidine residues (6 x His-tag) at the C-terminus of the 476 amino acid human CHKl . The protein was purified by conventional chromatographic techniques. CDK2/Cyclin A Construct for Assay: CDK2 was purified using published methodology (Rosenblatt et al., 7. Mol. Biol, 230, 1317-1319 (1993)) from insect cells that had been infected with a baculovirus expression vector. Cyclin A was purified from E. coli cells expressing full-length recombinant cyclin A, and a truncated cyclin A construct was generated by limited proteolysis and purified as described previously (Jeffrey et al., Nature, 376, 313-320 (1995)). CDK4/Cyclin D Construct for Assay: A complex of human CDK4 and cyclin D3, or a complex of cyclin Dl and a fusion protein of human CDK4 and glutathione- S-ttansferase (GST-CDK4), was purified using traditional biochemical chromatographic techniques from insect cells that had been co-infected with the corresponding baculovirus expression vectors. FAK Construct for Assay. The catalytic domain of human FAK (FAKcd409) was expressed using the baculovirus vector expression system. The 280 amino acid domain expressed comprises residues methionine 409 to glutamate 689. One amino acid substitation exists (P410T) relative to the sequence assession number LI 3616 published by Whithey, G.S. et al., DNA Cell Biol, 9, 823-30 (1993). The protein was purified using classical chromatography techniques. TIE-2 (TEK) Construct for Assay The TIE-2 tyrosine kinase domain was expressed in insect cells as an N- terminal deletion starting from amino acid residue 774 to the end of the protein at residue 1124. This construct also carries a R774M mutation, which serves as the initiating methionine residue in translation. VEGF-R2 Assay Coupled Spectrophotometric (FLVK-P) Assay The production of ADP from ATP that accompanies phosphoryl transfer was coupled to oxidation of NADH using phosphoenolpyruvate (PEP) and a system having pyruvate kinase (PK) and lactic dehydrogenase (LDH). The oxidation of NADH was monitored by following the decrease of absorbance at 340 nm (e 340 = 6.22 cm "1 mM "1 ) using a Beckman DU 650 spectrophotometer. Assay conditions for phosphorylated VEGF-R2Δ50 (indicated as FLVK-P in the tables below) were the following: 1 mM PEP; 250 μM NADH; 50 units of LDH/mL; 20 units of PK/mL; 5 mM DTT; 5.1 mM poly(E 4 Y ; 1 mM ATP; and 25 mM MgCl 2 in 200 mM HEPES, pH 7.5. Assay conditions for unphosphorylated VEGF-R2Δ50 (indicated as FLVK in the tables) were the following: 1 mM PEP; 250 μM NADH; 50 units of LDH/mL; 20 units of PK/mL; 5 mM DTT; 20 mM poly(E 4 Yι); 3 mM ATP; and 60 mM MgCl 2 and 2 mM MnCl 2 in 200 mM HEPES, pH 7.5. Assays were initiated with 5 to 40 nM of enzyme. Kj values were determined by measuring enzyme activity in the presence of varying concentrations of test compounds. The data were analyzed using Enzyme Kinetic and Kaleidagraph software. ELISA Assay Formation of phosphogastrin was monitored using biotinylated gasttin peptide (1-17) as substtate. Biotinylated phosphogastrin was immobilized using stteptavidin coated 96-well microtiter plates followed by detection using anti-phosphotyrosine- antibody conjugated to horseradish peroxidase. The activity of horseradish peroxidase was monitored using 2,2'-azino-di-[3-ethylbenzathiazoline sulfonate(6)] diammonium salt (ABTS). Typical assay solutions contained: 2 μM biotinylated gasttin peptide; 5 mM DTT; 20 μM ATP; 26 mM MgCl 2 ; and 2 mM MnCl2 in 200 mM HEPES, pH 7.5. The assay was initiated with 0.8 nM of phosphorylated VEGF-R2Δ50. Horseradish peroxidase activity was assayed using ABTS, 10 mM. The horseradish peroxidase reaction was quenched by addition of acid (H 2 SO 4 ), followed by absorbance reading at 405 nm. Kj values were determined by measuring enzyme activity in the presence of varying concentrations of test compounds. The data were analyzed using Enzyme Kinetic and Kaleidagraph software. FGF-R Assay The specttophotomettic assay was carried out as described above for VEGF-R2, except for the following changes in concenttation: FGF-R = 50 nM, ATP = 2 mM, and poly(E4Yl) = 15 mM. LCK Assay The specttophotomettic assay was carried out as described above for VEGF-R2, except for the following changes in concenttation: LCK = 60 nM, MgCl 2 = 0 mM, poly(E4Yl) = 20 mM. CHKl Assay The production of ADP from ATP that accompanies phosphoryl transfer to the synthetic substtate peptide Syntide-2 (PLARTLSVAGLPGKK) was coupled to oxidation of NADH using phosphoenolpyruvate (PEP) through the actions of pyruvate kinase (PK) and lactic dehydrogenase (LDH). The oxidation of NADH was monitored by following the decrease of absorbance at 340 nm (e 340 = 6.22 cm "1 mM "1 ) using a HP8452 spectrophotometer. Typical reaction solutions contained: 4 mN PEP; 0.15 mM NADH; 28 units of LDH/mL; 16 units of PK/mL; 3 mM DTT; 0.125 mM Syntide-2; 0.15 mM ATP; 25 mM MgCl 2 in 50 mM TRIS, pH 7.5; and 400 mM NaCl. Assays were initiated with 10 nM of FL-CHKl . K; values were determined by measuring initial enzyme activity in the presence of varying concentrations of test compounds. The data were analyzed using Enzyme Kinetic and Kaleidagraph software. CDK2/Cvclin A and CDK4/Cvclin D Assays Cyclin-dependent kinase activity was measured by quantifying the enzyme- catalyzed, time-dependent incorporation of radioactive phosphate from [32p]ATP into a recombinant fragment of the retinoblastoma protein. Unless noted otherwise, assays were performed in 96-well plates in a total volume of 50 μL, in the presence of 10 mM HEPES (N-[2-hydroxyethyl]piperazine-N'-[2-ethanesulfonic acid]) (pH 7.4), 10 mM MgCl2, 25 μM adenosine triphosphate (ATP), 1 mg/rnL ovalbumin, 5 μg/mL leupeptin, 1 mM dithiothreitol, 10 mM β-glycerophosphate, 0.1 mM sodium vanadate, 1 mM sodium fluoride, 2.5 mM ethylene glycol-bis(β-aminoethyl ether)- N,N,NN'-tetraacetic acid (EGTA), 2% (v/v) dimethylsulfoxide, and 0.03 - 0.2 μCi [32p]ATP. The substrate (0.3-0.5 μg) was purified recombinant retinoblastoma protein fragment (Rb) (residues 386-928 of the native retinoblastoma protein; 62.3 kDa, containing the majority of the phosphorylation sites found in the native 106-kDa protein, as well as a tag of six histidine residues for ease of purification). Reactions were initiated with CDK2 (150 nM CDK2/Cyclin A complex) or CDK4 (50 nM CDK4/Cyclin D3 complex), incubated at 30 °C, and terminated after 20 minutes (min.) by the addition of ethylenediaminetettaacetic acid (EDTA) to 250 mM. The phosphorylated substtate was then captured on a nitrocellulose membrane using a 96- well filtration manifold, and unincorporated radioactivity was removed by repeated washing with 0.85% phosphoric acid. Radioactivity was quantified by exposing the dried nitrocellulose membranes to a phosphorimager. Apparent K values were measured by assaying enzyme activity in the presence of different compound concentrations and subtracting the background radioactivity measured in the absence of enzyme. The kinetic parameters (kcat, Km for ATP) were measured for each enzyme under the usual assay conditions by determining the dependence of initial rates on ATP concentration. The data were fit to an equation for competitive inhibition using Kaleidagraph (Synergy Software), or were fit to an equation for competitive tight-binding inhibition using the software KineTic (BioKin, Ltd.). Measured K values for known inhibitors against CDK4 and CDK2 agreed with published IC 50 values. The specific activity of CDK4 was the same whether complexed to full-length cyclin D3 or the truncated Cyclin D3 construct; both complexes also yielded very similar K ; values for selected inhibitors. FAK Assay FAK HTS utilized the fluorescence polarization assay provided by LJL Biosystems. The kinase reaction contained: lOOmM Hepes pH 7.5, lOmM MgCl 2 , lmM DTT, lmM ATP, and lmg/ml poly Glu-Tyr (4:1). The reaction is initiated by the addition of 5nM FAKcd409. The reaction is terminated by the addition of EDTA followed by addition of fluor-labelled peptide and anti-phosphotyrosine antibody, both provided by LJL Biosystems. Inhibition results are read on a Analyst (LJL) detector. TJJE-2 Specttophotomettic Assay The kinase-catalyzed production of ADP from ATP that accompanies phosphoryl transfer to the random copolymer poly(Glu 4 Tyr) was coupled to the oxidation of NADH through the activities of pyruvate kinase (PK) and lactate dehydrogenase (LDH). NADH conversion to NAD + was monitored by the decrease in absorbance at 340 nm (ε = 6.22 cm'mM '1 ) using a Beckman DU650 spectrophotometer. Typical reaction solutions contained 1 mM phosphoenolpyruvate, 0.24 mM NADH, 40 mM MgCl 2 , 5 mM DTT, 2.9 mg/mL poly(Glu 4 Tyr), 0.5 mM ATP, 15 units/mL PK, 15 units/mL LDH in 100 mM HEPES, pH 7.5. Assays were initiated with the addition of 4 to 12 nM phosphorylated Tie-2 (aa 775-1122). Percent inhibition was determined in triplicate at a 1 μM level of inhibitor. TIE-2 DELFIA Assay Formation of phosphotyrosine was monitored using biotinylated p34cdc2 (aa6- 20 = KVEKIGEGTYGWYK) peptide as substrate. Biotinylated peptide was immobilized using NeuttAvidin™ coated 96-well microtiter plates followed by detection using anti-phosphotyrosine-antibody (PY20) conjugated to europium Nl chelate. Typical assay solutions contained: 1 μM biotinylated p34cdc2 peptide, 150 μM ATP, 5 mM MgCl 2 , 1 mM DTT, 0.01 % BSA, 5% glycerol, 2% DMSO, 25 mM HEPES pH 7.5. The assay was initiated in the NeuttAvidin plate with 50 nM of TIE2 inttacellular domain. The kinase reaction was terminated with 50 mM EDTA. Plates were then washed, and europium antibody added. After incubation, they were again washed, and DELFIA™ Enhancement Solution added. Plates were read at standard Europium time-resolved settings (ex 340 nm, em 615 nm, delay 400 μsec, window 400 μsec). Per cent inhibition was calculated with reference to inttaplate wells which had added DMSO rather than compound in DMSO, with background subttacted from both experimental and control with reference to an inttaplate well which had EDTA added prior to addition of enzyme. HUVEC Proliferation Assay This assay determines the ability of a test compound to inhibit the growth factor-stimulated proliferation of human umbilical vein endothelial cells ("HUVEC"). HUVEC cells (passage 3-4, Clonetics, Corp.) were thawed into EGM2 culture medium (Clonetics Corp) in T75 flasks. Fresh EGM2 medium was added to the flasks 24 hours later. Four or five days later, cells were exposed to another culture medium (F12K medium supplemented with 10% fetal bovine serum (FBS), 60 μg/mL endothelial cell growth supplement (ECGS), and 0.1 mg/mL heparin). Exponentially-growing HUVEC cells were used in experiments thereafter. Ten to twelve thousand HUVEC cells were plated in 96-well dishes in 100 μl of rich, culture medium (described above). The cells were allowed to attach for 24 hours in this medium. The medium was then removed by aspiration and 105 μl of starvation media (F12K+1% FBS) was added to each well. After 24 hours, 15 μl of test agent dissolved in 1% DMSO in starvation medium or this vehicle alone was added into each treatment well; the final DMSO concentration was 0.1%. One hour later, 30 μl of VEGF (30 ng/mL) in starvation media was added to all wells except those containing untreated controls; the final VEGF concenttation was 6 ng/mL. Cellular proliferation was quantified 72 hours later by MTT dye reduction, at which time cells were exposed for 4 hours MTT (Promega Corp.). Dye reduction was stopped by addition of a stop solution (Promega Corp.) and absorbance at 595 λ was determined on a 96-well specttophotometer plate reader. IC 50 values were calculated by curve-fitting the response of A 595 to various concenttations of the test agent; typically, seven concenttations separated by 0.5 log were employed, with triplicate wells at each concenttation. For screening compound library plates, one or two concentrations (one well per concenttation) were employed, and the % inhibition was calculated by the following formula: % inhibition = (control - test) ÷ (control - starvation) where control = A 595 when VEGF is present without test agent test = A 595 when VEGF is present with test agent starvation = A 595 when VEGF and test agent are both absent. Cancer Cell Proliferation (MV522) Assay The protocol for assessing cellular proliferation in cancer cells is similar to that used for assessments in HUVEC cells. Two thousand lung cancer cells (line MV522, acquired from American Tissue Cultural Collection) were seeded in growth media (RPMI1640 medium supplemented with 2 mM glutamine and 10% FBS). Cells are allowed to attach for 1 day prior to addition of test agents and /or vehicles. Cells are tteated simultaneously with the same test agents used in the HUVEC assay. Cellular proliferation is quantified by MTT dye reduction assay 72 hours after exposure to test agents. The total length of the assay is 4 days vs. 5 for HUVEC cells because MV522 cells are not exposed to starvation medium. Mouse PK Assay The pharmacokinetics (e.g., absorption and elimination) of drugs in mice were analyzed using the following experiment. Test compounds were formulated as a solution or suspension in a 30:70 (PEG 400: acidified H 2 0) vehicle or as a suspension in 0.5% CMC. This was administered orally (p.o.) and inttaperitoneally (i.p.) at variable doses to two distinct groups (n=4) of B6 female mice. Blood samples were collected via an orbital bleed at time points: 0 hour (pre-dose), 0.5 h, 1.0 h, 2.0 h, and 4.0 h, and 7.0 h post dose. Plasma was obtained from each sample by centrifugation at 2500 rpm for 5 min. Test compound was exttacted from the plasma by an organic protein precipitation method. For each time bleed 50 μL of plasma was combined with 1.0 mL of acetonitrile, vortexed for 2 min. and then spun at 4000 rpm for 15 min. to precipitate the protein and exttact out the test compound. Next, the acetonitrile supernatant (the exttact containing test compound) was poured into new test tubes and evaporated on a hot plate (25 °C) under a steam of N 2 gas. To each tube containing the dried test compound exttact 125 μL of mobile phase (60:40, 0.025 M NH 4 H 2 PO 4 +2.5 mL/L TEA: acetonitrile) was added. The test compound was resuspended in the mobile phase by vortexing and more protein was removed by centrifugation at 4000 rpm for 5 min. Each sample was poured into an HPLC vial for test compound analysis on an Hewlett Packard 1100 series HPLC with UV detection. From each sample, 95 μL was injected onto a Phenomenex-Prodigy reverse phase C- 18, 150 x 3.2 mm column and eluted with a 45-50% acetonitrile gradient run over 10 min. Test-compound plasma concentrations (μg/mL) were determined by a comparison to standard curve (peak area vs. cone. μg/mL) using known concentrations of test compound exttacted from plasma samples in the manner described above. Along with the standards and unknowns, three groups (n=4) of quality conttols (0.25 μg/mL, 1.5 μg/mL, and 7.5 μg/mL) were run to insure the consistency of the analysis. The standard curve had an R2> 0.99 and the quality controls were all within 10 % of their expected values. The quantitated test samples were plotted for visual display using Kalidagraph software and their pharmacokinetic parameters were determined using WIN NONLIN software. Example 1(a) provided the following results: 0.69 (Mouse pK, AUC, ip, μg-h/ml); 0.33 (Mouse pK, AUC, po, μg-h/ml). Human Liver Microsome (HLM) Assay Compound metabolism in human liver microsomes was measured by LC-MS analytical assay procedures as follows. First, human liver microsomes (HLM) were thawed and diluted to 5 mg/mL with cold 100 mM potassium phosphate (KPO4) buffer. Appropriate amounts of KPO4 buffer, NADPH-regenerating solution (containing B-NADP, glucose-6-phosphate, glucose-6-phosphate dehydrogenase, and MgCl 2 ), and HLM were preincubated in 13 x 100 mm glass tubes at 37 C for 10 min. (3 tabes per test compound-triplicate). Test compound (5 μM final) was added to each tube to initiate reaction and was mixed by gentle vortexing, followed by incubation at 37 °C. At t=0, 2 h, a 250-μL sample was removed from each incubation tabe to separate 12 x 75 mm glass tubes containing 1 mL ice-cold acetonitrile with 0.05 μM reserpine. Samples were centrifuged at 4000 rpm for 20 min. to precipitate proteins and salt (Beckman Allegra 6KR, S/N ALK98D06, #634). Supernatant was transferred to new 12 x 75 mm glass tubes and evaporated by Speed- Vac centrifugal vacuum evaporator. Samples were reconstituted in 200 μL 0.1% formic acid acetonitrile (90/10) and vortexed vigorously to dissolve. The samples were then transferred to separate polypropylene microcentrifuge tabes and centrifuged at 14000 x g for 10 min. (Fisher Micro 14, S/N M0017580). For each replicate (#1-3) at each timepoint (0 and 2 h), an aliquot sample of each test compound was combined into a single HPLC vial insert (6 total samples) for LC-MS analysis, which is described below. The combined compound samples were injected into the LC-MS system, composed of a Hewlett-Packard HP 1100 diode array HPLC and a Micromass Quattro TJ triple quadruple mass specttometer operating in positive electtospray SIR mode (programmed to scan specifically for the molecular ion of each test compound. Each test compound peak was integrated at each timepoint. For each compound, peak area at each timepoint (n=3) was averaged, and this mean peak area at 2 h was divided by the average peak area at time 0 hour to obtain the percent test compound remaining at 2 h. The results of the testing of the compounds using various assays are summarized in the table below, where a notation of "% @" indicates the percent inhibition at the stated concenttation, "*" values represent Ki (nM) or % inhibition at a compound concenttation of 1 μM for * or 50 nM for **, unless otherwise indicated. "NT' indicates no significant inhibition TABLE 1 TABLE 2 * values represent Ki (μM) or % inhibition at a compound concentration of 1 μM, unless otherwise indicated. Nl indicates no significant inhibition TABLE 3 * values represent Ki (μM) or % inhibition at a compound concentration of 1 μM, unless otherwise indicated. Nl indicates no significant inhibition LIBRARY EXAMPLE I X 1 in Table I + R 8 — CCfeH The three library building blocks ("amine templates") 6-(3-aminophenoxy)-3- E-styryl-1 H-indazole (Y = O), 6-(3-aminobenzoyl)-3-E-styryl-lH-indazole (Y = CO), and 6-(3-aminophenyl)amino-3-E-styryl-lH-indazole (Y = NH) were prepared as described in Example 7, Example 18, and Example 46 respectively. 0.1 M solutions of the acid, the amine template, σ-(7-azabenzotriazol-l-yl)-N,N,N',N'-tetra- methyluronium hexafluorophosphate and triethylamine were prepared separately in anhydrous DMF. To each tube in an array of 8X11 culture tubes (10x75 mm) was added 105 μL (0.0105 mmol) of a different acid. To this was added 100 μL (0.01 mmol) of the amine solution, 105 μL (0.0105 mmol) of the triethylamine solution followed by 105 μL (0.0105 mmol) of the σ-(7-azabenzotriazol-l-yl)-N,N,N',N'- tetra-methyluronium hexafluorophosphate solution. The reactions were stirred in a heating block at 50 °C for 3 h. The reaction mixtures were transferred to a 1 mL 96- well plate using a liquid handler. The solvents were removed using the SpeedVac™ apparatus and the crude reaction mixtures were redissolved in DMSO to give a final theoretical concentration of 10 mM. The compounds in the table were tested for inhibition of the proliferation of HUVEC at a nominal concentration of 10 nM, and the results are listed in Table I below, calculated from: % inhibition = (control-treated)/(control-starvation) x 100 Under these testing conditions, >50% inhibition is considered significant.

To each tube in an array of 8X11 culture tubes (10x75 mm) in the golvebox was added 100 μL (0.01 mmol) of the different amine solutions followed by the addition of 100 μL (0.01 mmol) tettabutylammorιium2-{3-[(E)-2-(2-pyridinyl)ethylyl]-lH-indazol-6- yl}sulfanyl)benzoate solution, 100 μL (0.01 mmol) of the triethylamine solution, 100 μL (0.01 mmol) of the 4-dimethylaminopyridine solution and 100 μL (0.01 mmol) of the o-(7-azabenzotriazol-l-yl)-N,N,N',N'-tetra-methyluronium hexafluorophosphate solution. The reactions were stirred in a heating block at 50 °C for 1 h. The reaction mixtures were transferred to a 1 mL 96-well plate using a liquid handler. The solvents were removed using the SpeedVac™ apparatus and the crude reaction mixtures were redissolved in DMSO to give a final theoretical concentration of 10 mM. The compounds in the table were tested for inhibition of the proliferation of HUVEC at a nominal concenttation of 0.5 nM, and the results are listed in Table m below, as calculated from: % inhibition = (control-tteated)/(control-starvation) x 100 Under these testing conditions, >30% inhibition is considered significant. LIBRARY TABLE HI R % inhibition R % inhibition TABLE 4 TABLE 5 * compound tested at 10 μM values in bold refer to spectrophotometric assay results; non-bolded values were obtained in a DELFIA assay Determination of Inhibitor Concentration in Mouse Plasma after Intraperitoneal and Oral Dosing The dosing solution consisted of the inhibitor dissolved in one of the following vehicles: either 30% or 60% aqueous polypropylene glycol solution with a molar equivalent of HCl in water, or 0.5% carboxymethylcellulose in water. The final concentration was normally 5 mg/ml with a dosing volume of 5 or 10 ml/kg. Taconic (Germantown, NY) female mice were dosed as a function of compound mass per body mass, usually 50 or 25 mg kg. Blood collection was via ocular bleed at 0.5, 1, 4 hr with the final time point, 7 hour, via intracardiac puncture. The blood was centrifuged to collect plasma, which was then stored at -80 °C until analysis. Samples were prepared for analysis using an internal standard and sodium hydroxide. After vortexing, ethyl acetate was added and mixed for 15-20 minutes at ambient temperature. Following centrifugation, the resulting organic layer was evaporated and subsequently reconstituted in acetonitrile and buffer. The samples were then analyzed via HPLC or LC-MS. Compound levels were quantitated by generating a standard curve of known compound concentration in mouse plasma. Compound levels were plotted as a function of time and analyzed to provide area under the concentration curve (AUC ng*hr/ml), maximum concentration (Cmax ng/ml), minimum concentration (Cmin or 7 hour trough ng/ml), and terminal half-life (Tl/2 hr). The results are shown in Table 6. TABLE 6 C9 /00Sfl/X3d 69CZ0/Ϊ0 OΛV In Vivo Assay of Retinal Vascular Development in Neonatal Rats The development of the retinal vascular in rats occurs from postnatal day 1 to posmatal day 14 (P1-P14). This process is dependent on the activity of VEGF (J. Stone, et al, J. Neurosci., 15, 4738 (1995)). Previous work has demonstrated that VEGF also acts as a survival factor for the vessels of the retina during early vascular development (Alon, et. al, Nat. Med., 1, 1024 (1995)). To assess the ability of specific compounds to inhibit the activity of VEGF in vivo, compounds were formulated in an appropriate vehicle, usually 50% polyethylene glycol, average molecular weight 400 daltons, and 50% solution of 300 mM sucrose in deionized water. Typically, two microliters (2 μl) of the drug solution was injected into the midvitreous of the eye of rat pups on postnatal day 8 or 9. Six days after the intravitreal injection, the animals were sacrificed and the retinas dissected free from the remaining ocular tissue. The isolated retinas were then subjected to a histochemical staining protocol that stains endothelial cells specifically (Lutty and McLeod, Arch. OphthalmoL, 110, 267 (1992 )), revealing the extent of vascularization within the tissue sample. The individual retinas are then flat-mount onto glass slides and examined to determine the extent of vascularization. Effective compounds inhibit the further development of the retinal vasculature and induce a regression of all but the largest vessels within the retina. The amount of vessel regression was used to assess the relative potency of the compounds after in vivo administration. Vessel regression is graded on subjective scale of one to three pluses, with one plus being detectable regression judged to be approximately 25 percent or less, two pluses being judged to be approximately 25-75 % regression and three pluses give to retinas with near total regression (approximately 75% or greater). For more quantitative analysis of regression, images of ADPase-stained, flat-mounted retinas were captured with a digital camera attached to a dissecting microscope. Retinal images were then imported into an image analysis software (Image Pro Plus 4.0, Media Cybernetics, Silver Spring, MD). The software was employed to determine the percentage of the area of the retina that contained stained vessels. This value for the experimental eye was compared to that measured for the vehicle injected, contralateral eye from the same animal. The reduction in the vascular area seen in the eye that received compound as compared to the vehicle-injected eye was then expressed as the "percent regression" for that sample. Percent regression values were averaged for groups of 5-8 animals. In samples in which observation through the microscope indicated near total regression, a percent regression value of 65-70% was routinely measured. This was due to stain deposits within folds of retina, folds that were induced by the vehicle used for drug injection. The image analysis software interpreted these stain-containing folds as vessels. No attempt was made to correct for these folds since they varied from eye to eye. Thus, it should be noted that the percent regression values reported result from a conservative measurement that accurately rank orders compounds, but underestimates their absolute potency. In Vivo Assay of Retinal Vascular Development in Neonatal Rat Model of Retinopathy of Prematurity A second model of VEGF dependent retinal neovascularization was employed to evaluate the activities of this series of compounds. In this model (Penn et. al, Invest. OphthalmoL Vis. Sci., 36, 2063, (1995)), rats pups (n=16) with their mother are placed in a computer controlled chamber that regulates the concentration of oxygen. The animals are exposed for 24 hours to a concentration of 50% oxygen followed by 24 hours at a concentration of 10% oxygen. This alternating cycle of hyperoxia followed by hypoxia is repeated 7 times after which the animals are removed to room air (PI 4). Compounds are administered via intravitreal injection upon removal to room air and the animals are sacrificed 6 days later (P20). The isolated retinas are then isolated, stained mounted and analyzed as detail above in the development model. The effectiveness was also graded as is described for the development model. TABLE 7 Phosphorylase Kinase Phosphorylase Kinase Construct for Assay. The truncated catalytic subunit (gamma subunit) of phosphorylase kinase (amino acids 1-298) was expressed in E.coli and isolated from inclusion bodies. Phosphorylase kinase was then refolded and stored in glycerol at -20 °C. Phosphorylase Kinase Assay. In the assay, the purified catalytic subunit is used to phosphorylate phosphorylase b using radiolabled ATP. Briefly, 1.5 mg/ml of phosphorylase b is incubated with 10 nM phosphorylase kinase in 10 mM MgCl 2 , 50 mM Hepes pH 7.4, at 37 °C. The reaction is started with the addition of ATP to 100 uM and incubated for 15 min at 25 °C or 37 °C. The reaction was terminated and proteins were precipitated by the addition of TCA to 10% final concentration. The precipitated proteins were isolated on a 96 well Millipore MADP NOB filter plate. The filter plate was then extensively washed with 20% TCA, and dried. Scintilation fluid was then added to the plate and incorporated radiolabel was counted on a Wallac microbeta counter. The % inhibition of phosphoryl transfer from ATP to phosphorylase b in the presence of 10 μM of compound is shown in the Table 8 below.
