Description: ANTIANGIOGENIC DRUG TO TREAT CANCER. ARTHRITIS AND RETINOPATHY Technical Field The present invention relates to compounds which are useful for treating pathological states which arise from or are exacerbated by angiogenesis, to pharmaceutical compositions comprising these compounds, and to methods of inhibiting angiogenesis in a mammal Background of the Invention Angiogenesis, the process by which new blood vessels are formed, is essential for normal body activities including reproduction, development and wound repair Although the process is not completely understood, it is believed to involve a complex interplay of molecules which regulate the growth of endothehal cells (the primary cells of capillary blood vessels) Under normal conditions, these molecules appear to maintain the microvasculature in a quiescent state (1 e one of no capillary growth) for prolonged periods which may last for as long as weeks or, in some cases, decades When necessary (such as during wound repair), these same cells can undergo rapid proliferation and turnover within a 5 day period (Folkman, J and Shmg, Y , The Journal of Biological Chemistry, 267(16), 10931-10934, (1992) and Folkman. J and Klagsbrun, M . Science, 235, 442-447 (1987) Although angiogenesis is a highly regulated process unde * * normal conditions, manv diseases (characterized as angiogemc diseases) are driven bv persistent unregulated angiogenesis Otherwise stated, unregulated angiogenesis may either cause a particular disease directly or exacerbate an existing pathological condition For example, ocular neovasculaπzation has been implicated as the most common cause of blindness and dominates approximately twenty eye diseases In certain existing conditions, such as arthritis, newly formed capillary blood vessels invade the joints and destroy cartilage In diabetes, new capillaries formed in the retina invade the vitreous, bleed, and cause blindness Growth and metastasis of solid tumors are also dependent on angiogenesis (Folkman, J , Cancer Research, 46, 467-473 (1986), Folkman, J , Journal of the National Cancer Institute, 82, 4-6 (1989) It has been shown, for example, that tumors which enlarge to greater than 2 mm must obtain their own blood supply and do so by inducing the growth of new capillary blood vessels Once these new blood vessels become embedded in the tumor, they provide a means for tumor cells to enter the circulation and metastasize to distant sites such as liver, lung or bone (Weidner, N., et al., The New England Journal of Medicine, 324(1), 1-8 (1991). Several angiogenesis inhibitors are currently under development for use in treating angiogenic diseases (Gasparim, G. and Harris, A. L., J. Clin. Oncol., 13(3): 765-782, (1995), but there are disadvantages associated with these compounds. Suramin, for example, is a potent angiogenesis inhibitor but causes severe systemic toxicity in humans at doses required for antitumor activity. Compounds such as retinoids, interferons and antiestrogens are relatively safe for human use but have weak antiangiogenic effects. Irsogladine, an anti-tumor drug with low toxicity, has only weak anti-angiogemc effects. Thus there is still a need for compounds useful in treating angiogenic diseases in mammals Summary of The Invention In one embodiment of the present invention are disclosed compounds represented by Formula I I, or a pharmaceutically acceptable salt or prodrug thereof, where R - and R*° are hydrogen or taken together are =0, R and are hydrogen or taken together are =0, R-**--* and R* are hydrogen or taken together are =0; R" and R" are hydrogen or taken together are =0; W, X, Y, and Z are independently selected from (1) hydrogen and (2) alkyl of one to six carbons, provided that when X, Y, and Z are hydrogen then, at least one of R-^ and R-^ or R and RD or R E and R F is other than =0; R! is selected from (1) hydrogen and (2) an amino protecting group; R2 and R3 are independently selected from (1) hydrogen and (2) alkyl of one to six carbons where the alkyl group is substituted with -NL--L-*-- where L-- and L- * - * are independently selected from (a) hydrogen, (b) alkyl of one to six carbons, and (c) an amino protecting group; R4 and R-* 5 are independently selected from (1) hydrogen (2) alkyl of one to six carbons, and (3) cycloalkyl of three to twelve carbon atoms; R*> and R^ are independently selected from (1) hydrogen, (2) alkyl of one to six carbons, and (3) alkyl of one to six carbons substituted with 1 or 2 substituents independently selected from (a) aryl and (b) aryl substituted with 1, 2, 3, 4, or 5 substituents independently selected from (i) -OH, (ii) -OL.3 where IP is alkyl of one to six carbons, (iii) alkyl of one to six carbons, (iv) halogen, (v) -Nθ2, and (vi) -NT 1 !- 2 ; R° and R" are independently selected from (1) hydrogen, (2) alkyl of one to six carbons, and (3) -CH2(CH2) m C02L 4 where L 4 is selected from (a) hydrogen and (b) alkyl of one to six carbons and m is an integer from 0 to 4, Rχo is selected from (1) -OL 5 where L is selected from (a) hydrogen, (b) alkyl of one to six carbons, (c) cycloalkyl of three to six carbons, and (d) alkyl of one to six carbons substituted with 1 or 2 substituents independently selected from (l) cycloalkyl of three to six carbons, (u) aryl, and (in) aryl substituted with 1, 2, 3, 4, or 5 substituents independently selected from -OH, -OL^ where L*- * is alkyl of one to six carbons, alkyl of one to six carbons, halogen, -Nθ2, and -NJ L 2 and (2) -NHL 5 In another embodiment of the invention are disclosed methods of treating diseases comprising administering an effective amount of a compound having Formula I In yet another embodiment of the invention are disclosed pharmaceutical compositions containing compounds of Formula I.

Compounds of the present invention can exist as stereoisomers where asymmetric or chiral centers are present. These compounds are designated by the symbols "R" or "S," depending on the configuration of substitiuents around the chiral carbon atom. The present invention contemplates various stereoisomers and mixtures thereof. Stereoisomers include enantiomers and diastereomers, and equal mixtures of enantiomers are designated (— ). Individual stereoisomers of compounds of the present invention can be prepared synthetically from commercially available starting materials which contain asymmetric or chiral centers or by preparation of racemic mixtures followed by resolution well-known to those of ordinary skill in the art. These methods of resolution are exemplified by (1) attachment of a mixture of enantiomers to a chiral auxiliary, separation of the resulting mixture of diastereomers by recrystallization or chromatography and liberation of the optically pure product from the auxiliary or (2) direct separation of the mixture of enantiomers on chiral chromatographic columns. Determination of Biological Activity Endothelial Cell Migration Assay The endothelial cell migration assay was performed essentially as described by Polverini, P.J. et al., Methods Enzymol, 198: 440-450 (1991). Briefly, Human Microvascular Endothelial Cells (HMVEC) were starved overnight in DMEM containing 0.1% bovine serum albumin (BSA). Cells were then harvested with trypsin and resuspended in DMEM with 0.1% BSA at a concentration of 1.5 x 10 6 cells/mL. Cells were added to the bottom of a 48-well modified Boyden chamber (Nucleopore Corporation, Cabin John, MD). The chamber was assembled and inverted, and cells were allowed to attach for 2 hours at 37 °C to polycarbonate chemotaxis membranes (5 μm pore size) that had been soaked in 0.1 % gelatin overnight and dried. The chamber was then reinverted and basic fibroblast growth factor (bFGF) and test substances were added to the wells of the upper chamber (to a total volume of 50 μL); the apparatus was then incubated for 4 hours at 37 °C. Membranes were recovered, fixed and stained (DiffQuick, Fisher Scientific, Pittsburgh, PA) and the number of cells that had migrated to the upper chamber per 10 high power fields were counted. Background migration to DMEM + 0.1% BSA was subtracted and the data reported as the number of cells migrated per 10 high power fields (400X) or when results from multiple experiments were combined, as the percent inhibition of migration compared to a positive control. The results are shown in Table 1.

When used in the above or other treatments, a therapeutically effective amount of one of the compounds of the present invention may be employed in pure form or, where such forms exist, in pharmaceutically acceptable salt form and with or without a pharmaceutically acceptable excipient. A "therapeutically effective amount" of the compound of the invention means a sufficient amount of the compound to treat an angiogenic disease (for example, to limit tumor growth or to slow or block tumor metastasis) at a reasonable benefit/risk ratio applicable to any medical treatment. It will be understood, however, that the total daily usage of the compounds and compositions of the present invention will be decided by the attending physician within the scope of sound medical judgment. The specific therapeutically effective dose level for any particular patient will depend upon a variety of factors including the disorder being treated and the severity of the disorder; activity of the specific compound employed; the specific composition employed; the age, body weight, general health, sex and diet of the patient; the time of administration; the route of administration; the rate of excretion of the specific compound employed; the duration of the treatment; drugs used in combination or coincidental with the specific compound employed and like factors well known in the medical arts. For example, it is well within the skill of the art to start doses of the compound at levels lower than those required to achieve the desired therapeutic effect and to gradually increase the dosage until the desired effect is achieved. Total daily dose of compounds of this invention to be administered locally or systemically to a human or other mammal host in single or divided doses may be in amounts, for example, from 0.01 to 200 mg/kg body weight daily and more usually 1 to 300 mg/kg body weight. If desired, the effective daily dose may be divided into multiple doses for purposes of administration Consequently, single dose compositions may contain such amounts or submultiples thereof to make up the daily dose. It will be understood that agents which can be combined with the compound of the present invention for the inhibition, treatment or prophylaxis of angiogenic diseases are not limited to those listed above, but include, in principle, any agents useful for the treatment or prophylaxis of angiogenic diseases.
