The combination of the benzopyran-4-one ring, a moiety found in the prototype leukotriene antagonist, FPL 55,712, with the (2-quinolinylmethoxy)phenyl group led to a significant increase in leukotriene receptor binding affinity. This modification resulted in a 10,000-fold improvement in binding affinity compared to FPL 55,712. Compound 7 (RG 12553), with a Ki value of 0.1 nM, has higher affinity than
苯并吡喃-4-酮环(在原型白三烯拮抗剂FPL 55,712中发现的部分)与(2-喹啉基甲氧基)苯基的组合导致白三烯受体结合亲和力显着增加。与FPL 55,712相比,这种修饰导致结合亲和力提高了10,000倍。Ki值为0.1 nM的化合物7(RG 12553)比天然激动剂LTD4具有更高的亲和力,并且是报道的最有效的LTD4拮抗剂之一。讨论了这一系列有效的白三烯拮抗剂的构效关系。
