Azadepsipeptides: Synthesis and Evaluation of a Novel Class of Peptidomimetics
摘要:
A general route to azadepsipeptides, a new class of pseudopeptides, has been established. The methodology was applied to the synthesis of a bis-aza analogue of the antiparasitic cyclooctadepsipeptide PF1022A. Comparison of the X-ray crystal structures of natural PF1022A (8) and the chimeric aza analogue 9 revealed that the introduction of nitrogen in the backbone of PF1022A results in almost complete conservation of the 3D structure with only minor deviations at the new nitrogen positions.
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.
