C34-epi and C34-epi-C35-trifluoro analogues of solamin, a mono-THF annonaceous acetogenin, were synthesized. Their inhibitory activity, along with previously synthesized analogues (C35-fluoro, C35-difluoro, and C35-trifluorosolamins), against bovine mitochondrial NADH-ubiquinone oxidoreductase (complex I) was determined. The present study revealed that the methyl group on the γ-lactone moiety is critical to the potent inhibition of complex I by natural acetogenins.
合成了单-THF 番荔枝内酯类化合物索拉明的 C34-epi 和 C34-epi-C35-三氟类似物,并测定了它们与之前合成的类似物(C35-氟、C35-二氟和 C35-三氟索拉明)对牛线粒体 NADH-泛醌氧化还原酶(复合物 I)的抑制活性。本研究表明,γ-内酯部分的甲基对于天然乙酰辅酶抑制剂对复合物 I 的强烈抑制作用至关重要。
