Invest., 1993, 91, 153). Neutralizing monoclonal antibodies to KDR have been shown to be efficacious in blocking tumor angiogenesis (Kim et al. Nature 1993, 36~, 841;
Rockwell et al. Mol. Cell. Differ. 1995, 3, 315).
Qver expression of VEGF, for example under conditions of extreme hypoxia, can lead to intraocular angiogenesis, resulting in hyperproliferation of blood vessels, leading eventually to blindness. Such a cascade of events has been observed for a number of retinopathies, including diabetic retinopathy, ischemic retinal-vein occlusion, retinopathy of prematurity (Aiello et al. Nevv L'ngl. J. Med. 1994, 331, 1480; Peer et al. Lab. Invest. 1995, 72, 638), and age-related macular degeneration (AMD; see, Lopez et al. Invest. Opththalmol. Yis. Sci. 1996, 37, 855).
In rheumatoid arthritis (RA), the in-growth of vascular pannus may be mediated by production of angiogenic factors. Levels of immunoreactive VEGF
are high in the synovial fluid of RA patients, while VEGF levels were low in the synovial fluid of patients with other forms of arthritis of with degenerative joint disease (Koch et al. J. Immuraol. 1994, 152, 4149). The angiogenesis inhibitor AGM-170 has been shown to prevent neovascularization of the joint in the rat collagen arthritis model (Peacock et al. J. Exper. Med. 1992, 175, 1135).
Increased VEGF expression has also been shown in psoriatic skin, as well as bullous disorders associated with subepidermal blister formation, such as bullous . pemphigoid, erythema multiforme, and dermatitis herpetiformis (Brown et al.
J.
Invest. Dermatol. 1995,104, 744).

General methods ,for,the preparation of the compounds are given below, and the preparation of a suitable compound is specifically illustrated in the Examples.
Ureas of formula (I) can be prepared by a variety. of simple methods known in the art. General approaches for the formation of those compounds can be found in "Advanced Organic Chemistry ", by J. March, John Wiley and Sobs, 1985 and in "Comprehensive Organic Transformations ", by R. ~ C.' Larock, TlCH Publishers, 1989), which are hereby incorporated by reference. Nevertheless, the ,following general preparative methods are presented to aid one of skill in the art in synthesizing these compounds, with more detailed examples being presented in the experimental section describing the working examples.
General Preparative Methods Heterocyclic amines may be synthesized utilizing known methodology (I~atritzky, et al. Comprehensive FIeteYOCyclic -Chemistry; Permagon Press:
Oxford, UI~ (1984). March. Advaneed Organic Chemistry, 3ra Ed.; John Wiley: New York (1985)). For example, as shown in Scheme I, 5-arninopyrazoles substituted at the N 1 position with either aryl or heteroaryl moieties may be synthesized by the reaction of an oc-cyanoketone (2) with the appropriate aryl- or heteroaryl hydrazine (3, R2=aryl or heteroaryl). Cyanoketone 2, in turn, is available from the reaction of acetarnidate ion with , an appropriate acyl derivative, such as an ester, an acid halide, or an acid anhydride. In cases where the R2 moiety offers suitable anion stabilization, 2-aryl-and-2-heteroarylfurans may be synthesized from a Mitsunobu,reaction of cyanoketone 2 with alcohol 5, followed by base catalyzed cyclization of enol ether 6 to give furylamine 7.

As shown in Scheme II, aryl amines are commonly synthesized by reduction of nitroaryls using a metal catalyst, such as Ni, Pd, or Pt, and Hz or a hydride transfer agent, such as formate, cyclohexadiene, or a borohydride (Rylander. Hydrogenation Methods;

Cu0 / base Scheme III Selected Nucleophilic Aromatic Substitution using Nitroaryls As shown in Scheme 1V, urea. formation may involve reaction of a heteroaryl
5 isocyanate (12) with an aryl amine (11). The heferoaryl isocyanate may be ynthesized from a heteroaryl amine by, treatment with phosgene or a phosgene equivalent, such ~s trichloromethyl chloroformate (diphosgene), bis(trichloromethyl) carbonate (triphosgene), or N,N'-carbonyldiimidazole (CDR. The isocyanate may also be derived from a heterocyclic carboxylic acid derivative, such as an ester, an acid 10 halide or an anhydride by a Curtius-type rearrangement. Thus, reaction of acid derivative 16 with an azide source, followed by rearrangement affords the isocyanate.
The corresponding carboxylic acid (17) may also ~ be subj ected to Curtius-type rearrangements using diphenylphosphoryl azide (DPPA) or a similar reagent. A
urea . may also be generated from the reaction of an aryl isocyanate (15) with a heterocyclic , arriine.

reactions (exemplified with 2-bromothiophene 25, Scheme V). Thus, reaction, of nitrile 20 with an oc-thioacetate ester gives 5-substituted-3-amino-2-thiophenecarboxylate 21 (Ishizaki et al. JP 6025221). Decarboxylafion of ester may be achieved by protection of the amine, for example as the test-butoxy~(BOC) carbamate (22), followed by saponification and treatment with acid. When BOC
protection is used, decarboxylation may be accompanied by deprotection giving the substituted 3-thiopheneammonium salt 23. Alternatively, ammonium salt 23 may be directly generated through saponification of ester 21 followed by treatment with acid.
Following urea formation as described above, bromination affords penultimate halothiophene 25. Palladium mediated cross coupling of thiophene 25 with an appropriate tributyl- or trimethyltin (Ra= aryl or heteroaryl) then affords the desired 2-aryl- or 2-heteroarylthienyl urea.

reactions (exemplified with 2-bromothiophene 25, Scheme V). Thus, reaction, of nitrile 20 with an oc-thioacetate ester gives 5-substituted-3-amino-2-thiophenecarboxylate 21 (Ishizaki et al. JP 6025221). Decarboxylafion of ester may be achieved by protection of the amine, for example as the test-butoxy~(BOC) carbamate (22), followed by saponification and treatment with acid. When BOC
protection is used, decarboxylation may be accompanied by deprotection giving the substituted 3-thiopheneammonium salt 23. Alternatively, ammonium salt 23 may be directly generated through saponification of ester 21 followed by treatment with acid.
Following urea formation as described above, bromination affords penultimate halothiophene 25. Palladium mediated cross coupling of thiophene 25 with an appropriate tributyl- or trimethyltin (Ra= aryl or heteroaryl) then affords the desired 2-aryl- or 2-heteroarylthienyl urea.

in half log dilutions. These dilutions were further diluted twenty fold in H20 to obtain compound solutions in 5% DMSO. Following loading of the assay plate with 85 ~l of assay buffer (20 mM HEPES, pH 7.5, 100 mM ICI, 10 xnM MgCl2, 3 mM
MnCl2, 0.05% glycerol, 0.005% Triton X-100, 1 mM -mercaptoethanol, with or 20 without 3.3 ~M ATP), 5 ~.I of the diluted compounds were added to a final assay volume of 100 ~.1. Final concentrations were between 10 p.M, and 0.3 mM in 0.25%
DMSO. The assay was initiated by the addition of 10,1 (30~ ng) of KI7R kinase domain.
25 The assay was incubated with test cornpourld or vehicle alone with gentle agitation at room temperature for 60 minutes. The wells were washed and phosphotyrosines (PY) were probed with ari anti-phosphotyrosine (PY), mAb clone 4610 (Upstate Biotechnology, Lake Placid, NY). PY/anti-PY complexes were detected with an anti-mouse IgG/I3RP conjugate Iamersham International plc, 30 Buckinghamshire, England). Phosphotyrosine was quantitated by incubating with '100 ~,l 3, 3', 5, 5' tetramethylbenzidine solution (Kirkegaard and Perry, TMB
Microwell 1 Component peroxidase substrate). Color development was arrested by the addition of . . ~ 41 100 ~,l 1% HCl-based stop solution (Kirkegaard and Perry, TMB 1 Component Stop Solution).
Optical densities were determined spectrophotometrically at 450 nm in a 96-well plate reader, SpectraMax 250 (Molecular Devices). Background (no ATP in assay) OD values were subtracted from all Ods and the percent inhibition was calculated according to the equation:
Inhibition = (OD(vehicle controll - OD (with compound) X 100 OD (vehicle control) - OD (no ATP added) The ICSO values were determined with a least squares analysis program using compound concentration versus percent inhibition.
The following compounds were tested in the assay described above and were found to have either an ICSO of less than 10 micromolar or showed greater than 30%
inhibition at 1 micromolar. Compound names were generated using NomenclatorTM v 3.0 and may differ from those in the patent applications.

Fifteen thousand cells are plated into each well of a collagen I-coated 96-well plate in the DMEM growth medium. Six hours later, the cells are washed and the medium is replaced with DMEM without serum. After overnight culture to quiesce the cells,t he medium is replaced by Dulbecco's phosphate-buffered saline (Life Technologies Inc., Grand Island, NY) .with 0.1% bovine albumin (Sigma Chemical Co., St. Louis, MO). After adding various concentrations (0-300 nM) of test compounds to the cells 'in 1% final concentration of DMSO, the cells are incubated at room temperature for 30 minutes. Following VEGF stimulation, the . buffer is removed and the cells are lysed by addtion of 150 wl of extraction buffer (50 mlVl Tris, pH 7.8, supplemented with 10% glycerol, 50 mM BGP, 2 mM EDTA, 10 mM NaF, 0.5 mM NaV04, and 0.3% TX-100) at 4°C for 30 minutes.
5 To assess receptor pliosphorylation, 100 microliters of each cell lysate are added to the wells of an ELISA plate precoated with 300 ng of antibody C20 (Santa Cruz Biotechnology, Inc., Santa Cruz, CA). Following a 60-minute incubation, the plate is washed and bound KDR is probed for phosphotyrosine using an anti-phosphotyrosine mAb clone 4610 (Upstate Biotechnology, Lake Placid, NY). The 10 plate is washed and wells are incubated with anti-mouse IgG/HRP conjugate (Amersham International plc, Buckinghamshire, England) for 60 minutes. Wells are washed and phosphotyrosine is quantitated by addition of 100 ~,1 per well of 3,3',5,5' tetrarnethylbenzidine (I~irkegaard and Ferry, TMB 1 Component Stop Solution).

Matrig_el~o~enesis Model:
Preparation of Martigel Plugs and in vivo Phase: Matrigel~ (Collaborative Biomedical Products, Bedord, MA) is a basement membrane extract from a murine tumor composed primarily of laminin, collagen IV and heparan sulfate proteoglycan.
It is provided as a sterile liquid at 4°C, but rapidly forms a solid gel at 37°C.
Liquid Matrigel at 4°C is mixed with SK-MEL2 human tumor cells that are transfected with a plasmid containing the marine VEGF gene with a selectable marker. Tumor cells are grown in ~it~o under selection and cells are mixed with cold liquid Matrigel at a ratio of 2 X 106 per 0.5 ml. . One half milliliter is implanted subcutaneously near the abdominal midline using a 25 gauge needle. Test compounds are dosed as solutions in Ethanol/Ceremaphor EL/saline (12.5%:12.5%:75%) at 30, 100, and 300 mg/kg .po once daily starting on the day of implantation. Mice are euthanized 12 days post-implantation and the Matrigel pellets are harvested for analysis of hemoglobin content.
Hemoglobin Assay: The Matrigel pellets are placed in 4 volumes (w/v) of 4°C
Lysis Buffer (20mM Tris pH 7.5, 1mM EGTA, 1mM EDTA, 1% Triton X-100 [EM
Science, Gibbstown, N.J.], and complete EDTA-free protease inhibitor cocktail [Mannheim, Germany]), and homogenized at 4°C. homogenates are incubated on ice for 30 minutes with shaking and centrifuged at 14.K x g for 30 minutes at 4°C.
Supernatants are transferred to chilled microfuge tubes and stored at 4°C for hemoglobin assay:
Mouse hemoglobin (Sigma Chemical Co., St. Louis, MO) is suspended in autoclaved water .(BioWhittaker, Inc, Walkersville, MD.) at 5 mg/ml. ~ A
standard curve is generated from 500 micrograms/ml to 30 micrograms/rnl in Lysis Buffer (see above). Standard curve and lysate samples are added at 5 microliters/well in duplicate to a polystyrene 96-well plate. Using the Sigma Plasma Hemoglobin Kit (Sigma Chemical Co., St. Louis, MO), TMB substrate is reconstituted in 50 mls room temperature acetic acid solution. One hundred microliters of substrate is added to each well, folloyved by 100 microliters/well of Hydrogen Peroxide Solution at room temperature. The plate is incubated at room temperature for 10 minutes.
Optical densities are determined spectrophotometrically at 600 nm in a 96-well plate reader, SpectraMax 250 Microplate Spectrophotometer System (Molecular Devices, Sunnyvale, CA). Background Lysis Buffer readings are subtracted from all wells.
Total sample hemoglobin content is calculated according to the following equation:
Total Hemoglobin = (Sample Lysate Volume) x (Hemoglobin Concentration) The average Total Hemoglobin of Matrigel samples without cells is subtracted from each Total Hemoglobin Matrigel sample with cells. Percent inhibition is calculated according to the following equation:
Inhibition = ~Avera~e Total Hemoglobin Drug-Treated. Tumor Lysates) X 100 (Average Total Hemoglobin Non-Treated Tumore Lysates).

Test compounds are dosed as solutions in Ethanol/Ceremaphor EL/saline (12.5%:12.5%:75%) at 30, 100, and 300 mg/kg .po once daily starting on the day of implantation. Mice are euthanized 12 days post-implantation and the Matrigel pellets are harvested for analysis of hemoglobin content.
Hemoglobin Assay: The Matrigel pellets are placed in 4 volumes (w/v) of 4°C
Lysis Buffer (20mM Tris pH 7.5, 1mM EGTA, 1mM EDTA, 1% Triton X-100 [EM
Science, Gibbstown, N.J.], and complete EDTA-free protease inhibitor cocktail [Mannheim, Germany]), and homogenized at 4°C. homogenates are incubated on ice for 30 minutes with shaking and centrifuged at 14.K x g for 30 minutes at 4°C.
Supernatants are transferred to chilled microfuge tubes and stored at 4°C for hemoglobin assay:
Mouse hemoglobin (Sigma Chemical Co., St. Louis, MO) is suspended in autoclaved water .(BioWhittaker, Inc, Walkersville, MD.) at 5 mg/ml. ~ A
standard curve is generated from 500 micrograms/ml to 30 micrograms/rnl in Lysis Buffer (see above). Standard curve and lysate samples are added at 5 microliters/well in duplicate to a polystyrene 96-well plate. Using the Sigma Plasma Hemoglobin Kit (Sigma Chemical Co., St. Louis, MO), TMB substrate is reconstituted in 50 mls room temperature acetic acid solution. One hundred microliters of substrate is added to each well, folloyved by 100 microliters/well of Hydrogen Peroxide Solution at room temperature. The plate is incubated at room temperature for 10 minutes.
Optical densities are determined spectrophotometrically at 600 nm in a 96-well plate reader, SpectraMax 250 Microplate Spectrophotometer System (Molecular Devices, Sunnyvale, CA). Background Lysis Buffer readings are subtracted from all wells.
Total sample hemoglobin content is calculated according to the following equation:
Total Hemoglobin = (Sample Lysate Volume) x (Hemoglobin Concentration) The average Total Hemoglobin of Matrigel samples without cells is subtracted from each Total Hemoglobin Matrigel sample with cells. Percent inhibition is calculated according to the following equation:
Inhibition = ~Avera~e Total Hemoglobin Drug-Treated. Tumor Lysates) X 100 (Average Total Hemoglobin Non-Treated Tumore Lysates).
