A series of novel cyclic marinopyrroles were designed and synthesized. Their activity to disrupt the binding of the pro-apoptotic protein, Bim, to the pro-survival proteins, Mcl-1 and Bcl-xL, was evaluated using ELISA assays. Both atropisomers of marinopyrrole A (1) show similar potency. A tetrabromo congener 9 is two-fold more potent than 1. Two novel cyclic marinopyrroles (3 and 4) are two- to seven-fold more potent than 1.
设计并合成了一系列新型环状海洋吡咯。通过ELISA实验评估了它们破坏促凋亡蛋白Bim与促生存蛋白Mcl-1和Bcl-xL结合的活性。海洋吡咯A(1)的两种对映异构体显示出相似的效力。四溴类似物9的效力是1的两倍。两个新型环状海洋吡咯(3和4)的效力是1的两到七倍。
