Design, synthesis and biological evaluation of nonpeptide integrin antagonists
摘要:
Recent studies demonstrated that peptide and antibody antagonists of integrin alpha(v)beta(3) 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/alpha-aminoacid/guanidine framework and incorporates a novel nitroaryl system. The synthesized mimetics were tested against a variety of integrins (alpha(v)beta(3), alpha(IIb)beta(3), and alpha(v)beta(5)) 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 alpha(IIb)beta(3) (IC50 = 14 nM) whereas compound 11 showed excellent in vivo inhibition of angiogenesis (at 30 mu g/embryo).

The present invention provides compounds of the general formula (I), their salts and N- oxides, and solvates and prodrugs thereof (wherein the substituents are as defined in the description). The compounds of the general formula (I) are inhibitors of factor XIa, and are useful in the prevention of and/or therapy for thromboembolic diseases.
Synthesis of a 1,10-diphenanthryl all-trans fused perhydrophenanthrene derivative and a recognition study in an aqueous media were carried out. A water-soluble derivative recognized certain benzene derivatives with 104–105 M−1 of binding constant.
