D-Arg[Hyp3-Thi5-D-Tic7-Tic8]-bradykinin (NPC 16731) inhibited bradykinin (BK) binding and BK-induced contraction in guinea-pig ileum, being markedly more potent than D-Phe7-BK analogues as a BK2 receptor antagonist. In isolated trachea NPC 16731, unlike other BK2 antagonists, inhibited BK binding and BK-induced contraction, and 45Ca2+ efflux in tracheal smooth muscle cells. That NPC 16731 potently inhibits BK effects in trachea provides further evidence for the existence of the airway BK3 receptor.
D-精氨酸[Hyp3-硫代5-D-噻唑烷7-噻唑烷8]-缓激肽(NPC 16731)抑制豚鼠回肠中缓激肽(BK)的结合及BK诱导的收缩,作为BK2受体拮抗剂,其效力明显强于D-苯丙氨酸7-BK类似物。在离体气管中,与其他BK2拮抗剂不同,NPC 16731抑制BK的结合、BK诱导的收缩以及气管平滑肌细胞中的45Ca2+外流。NPC 16731有效抑制气管中BK的作用,为气道BK3受体的存在提供了进一步证据。
