A series of trisubstituted pyridines have been prepared that exhibit in vitro leukotriene B4 (LTB4, 1) receptor antagonist activity. Previous disubstituted pyridines from these labs showed high affinity for the LTB4 receptor but demonstrated agonist activity in functional assays (e.g., 2, Ki = 1 nM). Compound 4, the initial lead compound of this new series, showed only modest affinity by comparison
已经制备了显示体外白三烯B4(LTB4,1)受体拮抗剂活性的一系列三取代吡啶。来自这些实验室的先前的二取代吡啶对LTB4受体显示出高亲和力,但在功能分析中显示出激动剂活性(例如,2 Ki = 1 nM)。通过比较,化合物4(该新系列的初始先导化合物)仅显示出适度的亲和力(Ki = 282 nM);然而,4是一种受体拮抗剂,至多10 microM都没有明显的激动剂活性。脂质尾部和芳基头部区域的后续修饰导致了苯胺50的发现(SB 201146)。该化合物也没有激动剂活性,对LTB4受体具有高亲和力(Ki = 4.7 nM)。
