摘要:
In order to generate novel compounds with integrin alpha(v)beta(3)-antagonistic activity together with antiplatelet activity, tricyclic pharmacophore-based molecules were designed and synthesized. Although piperazine-containing compounds initially prepared were selective alpha(IIb)beta(3) antagonists, replacement of piperazine with piperidine furnished a potent alpha(v)beta(3)/alpha(IIb)beta(3) dual antagonist. Structureactivity relationship (SAR) studies provided clues for further development of tricyclic pharmacophore-based integrin antagonists. (c) 2005 Elsevier Ltd. All rights reserved.
