We investigated the effect of the nonpeptide bradykinin receptor antagonist, [[4-[[2-[[bis(cyclohexylamino)methylene] amino]-3-(2-naphthalenyl) 1-oxopropyl]amino]-phenyl]-tributyl, chloride, monohydrochloride (WIN 64338), on [3H]-bradykinin binding and on bradykinin-induced contraction of the guinea-pig trachea. This non peptide bradykinin receptor antagonist inhibited [3H]-bradykinin binding with a nanomolar range of affinity, Ki = 50.9 +/- 19 nM and inhibited bradykinin-induced contraction in a non-competitive manner with a KB value of 6.43 10(-8) +/- 2.34 10(-8) M.
我们研究了非肽类缓激肽受体拮抗剂[[4-[[2-[[双(环己基氨基)亚甲基]氨基]-3-(2-萘基)-1-氧代丙基]氨基]苯基]-三丁基氯化铵,单盐酸盐(WIN 64338)对豚鼠气管[3H]-缓激肽结合及缓激肽诱导收缩的影响。这种非肽类缓激肽受体拮抗剂以纳摩尔范围的亲和力抑制[3H]-缓激肽结合,Ki = 50.9±19 nM,并以非竞争性方式抑制缓激肽诱导的收缩,KB值为6.43×10(-8)±2.34×10(-8) M。
