A series of trisubstituted benzenes which demonstrate leukotriene B4 (LTB4, 1) receptor affinity was prepared. Previous trisubstituted benzenes from our laboratory showed high affinity to the LTB4 receptor but demonstrated agonist activity in functional assays. Compound 3a, the initial lead compound of this new series, showed only modest affinity (IC50 = 0.20 microM). However, 3a was a receptor antagonist
制备了一系列显示白三烯B4(LTB4,1)受体亲和力的三取代苯。我们实验室以前的三取代苯对LTB4受体显示出高亲和力,但在功能测定中显示出激动剂活性。该新系列的初始前导化合物化合物3a仅表现出适度的亲和力(IC50 = 0.20 microM)。但是,3a是一种受体拮抗剂,在高达30 microM时没有明显的激动剂活性。脂质尾部和芳基头部区域的进一步修饰导致3b(ONO-4057)的发现。该化合物无激动剂活性,对LTB4受体具有高亲和力(Ki = 3.7 +/- 0.9 nM)。
