A series of novel chromone derivatives, in which the chromone moiety is connected to a (diphenylmethylene)-, (diphenylmethyl)-, or (diphenylmethoxy)piperidine via an alkyloxy spacer, were synthesized as antiallergic and antiasthmatic agents. In addition to their potent antihistaminic activity, the compounds also inhibit contraction in guinea pig ileum induced by leukotriene D4. When analyzed by radioligand
合成了一系列新的色酮衍生物,其中色酮部分通过烷氧基间隔基与(二苯基亚甲基)-,(二苯基甲基)-或(二苯基甲氧基)哌啶连接,作为抗过敏和抗哮喘药。除了具有有效的抗组胺活性外,这些化合物还抑制白三烯D4诱导的豚鼠回肠收缩。当通过放射性配体结合测定法在豚鼠肺膜中分析时,化合物之一7-[[[3- [4-(二苯基亚甲基)哌啶-1-基]丙基]氧基] -2-(5-四唑基)-4- oxo-4H-1-苯并吡喃对H1-和LTD4-受体的离解常数(KD)分别为5.62 nM和2.34 microM。在体内剂量为10 mg / kg时,该化合物分别抑制组胺和LTD4诱导的豚鼠血管通透性增加95%和30%。当使用50 mg / kg的剂量时,该化合物对LTD4诱导的血管通透性增加的抑制作用增加至56%。与特非那定相似,当腹膜内给予小鼠时,该化合物不会轻易占据大脑中的H1受体,这意味着没有镇静作用。
