acid) with a novel N-substituted indole scaffold to interfere Mcl-1 binding as a novel Mcl-1 inhibitor. Molecular modeling indicated that this compound binds with Mcl-1 by interaction with P2 and R263 hot-spots. Structure modification focused on several moieties including indole core, hydrophobic tail and acidic chain were conducted and structure-activity relationship was analyzed. The most potent compound
髓样细胞白血病1(Mcl-1)是一种重要的抗凋亡蛋白,通过蛋白-蛋白相互作用发挥功能。我们发现了带有新型N-取代的吲哚骨架的LSL-A6(2-((2-氨基甲酰基-1-(3-(4-甲氧基苯氧基)丙基)-1H-吲哚-6-基)氧基)乙酸Mcl-1结合作为一种新型Mcl-1抑制剂。分子建模表明该化合物通过与P2和R263热点相互作用与Mcl-1结合。对吲哚核,疏水尾和酸性链等多个部分进行了结构修饰,并分析了结构-活性关系。经铅-铅修饰后,获得了最强的化合物24d,其显示出110nM的Ki值可干扰Mcl-1的结合。
