marinopyrroles with sulfide and sulphone spacers 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. Fluorescence-quenching (FQ) assays confirmed the direct binding of marinopyrroles to Mcl-1. Benzyl- and benzyl methoxy-containing sulfide derivatives 4 and 5 were highly potent
设计并合成了一系列具有硫化物和砜间隔基的新型马里诺吡咯。它们破坏促凋亡蛋白 Bim 与促存活蛋白 Mcl-1 和 Bcl-xL 结合的活性使用 ELISA 测定法进行评估。荧光猝灭 (FQ) 测定证实了 marinopyrroles 与 Mcl-1 的直接结合。含苄基和苄基甲氧基的硫化物衍生物 4 和 5 是高效的双重 Mcl-1/Bim 和 Bcl-xL/Bim 干扰物(IC50 值为 600 和 700 nM),而含羧酸盐的硫化物衍生物 9 表现出更高的 16.4 倍通过 Bcl-xL/Bim 结合破坏 Mcl-1/Bim 的选择性。此外,非对称 marinopyrrole 12 与母体 marinopyrrole A (1) 一样有效,可破坏 Mcl-1/Bim 和 Bcl-xL/Bim 结合。
