  Novel small molecule bradykinin B1 receptor antagonists. Part 1: Benzamides and semicarbazides

  摘要：

  The synthesis and SAR of two series of bradykinin B-1 receptor antagonists is described. The benzamide moiety proved to be a suitable replacement for the aryl ester functionality of biaryl based antagonists. In addition, it was found that semicarbazides can effectively replace cyclopropyl amino acids. The compounds with the best overall pro. le were biaryl semicarbazides which display high antagonistic activity, low Caco-2 efflux and high oral bioavailability in the rat. (C) 2009 Elsevier Ltd.
