Biphenyls as potent vitronectin receptor antagonists. Part 2: biphenylalanine ureas
摘要:
Vitronectin receptor (alpha(v)beta(3)) antagonism has been implicated in a variety of disease states, like restenosis, osteoporosis and cancer. In this work, we present the development of a novel class of biphenyl vitronectin receptor antagonists. Identified from a focused combinatorial library based on para-bromo phenylalanine, these compounds show nanomolar affinity to the vitronectin receptor and display unprecedented SAR. Their binding mode can be rationalized by computational docking studies using the X-ray structure of alpha(v)beta(3). (C) 2003 Elsevier Science Ltd. All rights reserved.
