  R-Isomers of Arg-Gly-Asp (RGD) mimics as potent αvβ3 inhibitors

  摘要：

  The integrin alpha(v)beta(3), vitronectin receptor, is expressed in a number of cell types and has been shown to mediate adhesion of osteoclasts to bone matrix, vascular smooth muscle cell migration, and angiogenesis. We recently disclosed the discovery of a tripeptide Arg-Gly-Asp (RGD) mimic, which has been shown to be a potent inhibitor of the integrin alpha(v)beta(3) and has excellent anti-angiogenic properties including its suppression of tumor growth in animal models. In other investigations involving RGD mimics, only compounds containing the S-isomers of the beta-amino acids have been shown to be potent. We were surprised to find the potencies of analogs containing enantiomerically pure S-isomers of beta-amino acids which were only marginally better than the corresponding racemic mixtures. We therefore synthesized RGD mimics containing R-isomers of beta-amino acids and found them to be relatively potent inhibitors of alpha(v)beta(3). One of the compounds was examined in tumor models in mice and has been shown to significantly reduce the rate of growth and the size of tumors. (c) 2007 Elsevier Ltd. All rights reserved.

  A practical, large-scale synthesis of a β-amino ester 1 was developed. A chiral imine derived from (S)-phenylglycinol and 3-trimethylsilylpropanal was coupled with the Reformatsky reagent 3 with high diastereoselectivity (de > 98%) to give (SS)-4a as the major isomer. The amino alcohol residue of the coupling product 4 was oxidatively cleaved with sodium periodate in the presence of methylamine. An
