[D-His2] Leu-enkephalin and [D-His2] adrenorphin were synthesized. In addition, eight [D-Arg2] enkephalin-related peptides were synthesized. Their inhibitory effects on electrically stimulated myenteric plexus-longitudinal muscle preparations of guinea-pig ileum were examined.
合成了[D-His2] Leu-
脑啡肽和[D-His2] 肾上腺
啡肽。此外,还合成了八种[D-Arg2]
脑啡肽相关肽。研究了这些肽对电刺激豚鼠回肠肠肌丛纵肌制备物的抑制作用。
