The synthesis of a new class of oxytocin antagonists
摘要:
The synthesis of a new class of oxytocin antagonists, with significantly modified C-terminal part, is described. The chemistry of the Mitsunobu reaction was applied to obtain the key derivatives. In spite of the extensive modifications of previously described compound F792, the peptides retain biological activity as oxytocin antagonists. (C) 1999 Elsevier Science Ltd. All rights reserved.

Bacterialpeptidoglycan is a mesh‐like network comprised of sugars and oligopeptides. Transpeptidases cross‐link peptidoglycan oligopeptides to provide vital cellwall rigidity and structural support. It was recently discovered that the same transpeptidases catalyze the metabolic incorporation of exogenous D‐amino acids onto bacterialcell surfaces with vast promiscuity for the side‐chain identity
