Neopeltolide, a natural product isolated from deep-water sponge specimen of the family neopeltidae, has been proven to be a novel inhibitor of cytochrome bc1. In this study, a series of neopeltolide derivatives was designed by replacing the 14-membered macrolactone with indole ring and confirmed by 1H NMR, 13C NMR, and HRMS. Based on the binding mode of 12h with bc1 complex, the IC50 values of compounds
Neopeltolide是从新科科的深水海绵标本中分离出的天然产物,已被证明是细胞色素bc 1的新型抑制剂。在这项研究中,通过用吲哚环取代14元大内酯来设计一系列新pelolidelide衍生物,并通过1 H NMR,13 C NMR和HRMS证实。基于12h与bc 1配合物的结合模式,化合物16a-f的IC 50值(范围从0.70至1.46μM)比酯衍生物12a-u显着提高通过用酰胺连接基取代酯。随后,分子对接结果表明化合物16e可与Phe274形成π-π相互作用,并与Glu271和His161形成两个H键,并且发现后者的H键是其高活性的原因。本工作加快了新型bc 1复合抑制剂的发现,以解决现有bc 1复合抑制剂面临的抗药性,并为设计新的杀菌剂提供了有价值的想法。
