The present invention provides compounds having formula (I) wherein n, p, q and r are each independently selected from 0 or 1; a, b, c, and d each independently represents a carbon or nitrogen atom, with the proviso that no more than two of a, b, c, and d are nitrogen atoms; Y and Y' each independently represents 1-4 optional substituents selected from alkyl, alkoxy, halo, -CF3, and -C(O)OH; R, R, R and R are H or specified substituents; R, R, R, R, R, R, R and R are independently selected from H or C1-C3 alkyl; or a biolabile ester thereof, or a pharmaceutically acceptable salt thereof. Also provided are methods of using these compounds for treating vitronectin-mediated disorders, e.g., cancer, retinopathy, artherosclerosis, vascular restenosis, and osteoporosis.

Recent studies demonstrated that peptide and antibody antagonists of integrin α(v)β3 block angiogenesis and tumor growth. In this article, the design, synthesis and biological evaluation of a series of nitroaryl ether-based, nonpeptide mimetics are described. The design of these compounds was based on Merck's arylether/α-aminoacid/guanidine framework and incorporates a novel nitroaryl system. The synthesized mimetics were tested against a variety of integrins (α(v)β3, α(IIb)β3, and α(v)β5) in order to determine their binding selectivity and ability to inhibit cell adhesion. Selected compounds were also tested for their ability to inhibit angiogenesis in vivo in the CAM (chick chorioallantoic membrane) assay. From the generated compound library, compounds 16 and 19 proved to be potent and selective inhibitors of α(IIb)β3 (IC50=14nM) whereas compound 11 showed excellent in vivo inhibition of angiogenesis (at 30μg/embryo).
