摘要

Abstract Acylated pentapeptide X Phe Phe Gly Leu MetNH 2 analogs of the substance P (7–11) sequence were synthesized by solution method and their spasmogenic activities were evaluated on guinea pig ileum (GPI) and trachea (GPT). Pentapeptide SP (7– 11) had the lowest potency and its N-acylation increased its activity in both tests, with some derivatives being more active than SP itself. Results obtained on GPI suggest a close ...
