Oligomycin complex consists of a blend of oligomycins A, B, and C. Oligomycin is a class of similar 26-membered macrolide antibiotics isolated from Streptomyces amylase chromogenes. Oligomycin has antifungal activity, oxidative phosphorylation inhibition and insecticidal activity[1].Oligomycin A primarily exerts its inhibitory effect on mitochondrial oxidative phosphorylation by blocking the proton channel (F0 subunit) of ATP synthase, thus inhibiting ATP synthesis. Additionally, it reduces the compensatory increase in oxidative phosphorylation in tumor cells, leading to a decrease in cellular glycolysis levels[2-4].Oligomycin B acts as a non-selective inhibitor of ATP synthases, effectively slowing down ATP depletion in cases of myocardial ischemia. Oligomycin C is an inhibitor of mitochondrial F1F0-ATP synthase, which induces more sensitive cell death and shifts the cell death pattern from apoptosis to necrosis.
Oligomycin(0-50µg/ml; 24h) induced mitochondrial membrane depolarization and cytochrome c release in HepG2 and R-HepG2 cells[5].Oligomycin A(0-16 µM;12-48 h) promotes HT29 cell survival and proliferation[6]. In A549 cells, 100 ng/ml Oligomycin could completely inhibit OXPHOS phosphorylation activity in 1 hour and stimulate various levels of glycolysis gains[7]. 5 µg/ml Oligomycin could inhibit the F0 part of H+-ATP-synthase, and strongly suppress cytochrome c release and apoptosis in Hela cells induced by TNF[8]. Oligomycin B(1 µM) induced vasodilations that were 39-61% smaller in sulfonylurea receptor 2 null (SUR2(nl)) than in SUR2 wild-type (SUR2(wt)) arteries[9].

寡霉素复合物(Oligomycin complex)由寡霉素A、B和C的混合物组成。寡霉素是从链霉菌淀粉酶色素中分离出来的一类类似26元大环内酯类抗生素。寡霉素具有抗真菌、氧化磷酸化抑制和杀虫活性[1-2]。寡霉素A主要通过阻断ATP合酶的质子通道(F0亚基),抑制ATP的合成来发挥其对线粒体氧化磷酸化的抑制作用。此外,它减少了肿瘤细胞中氧化磷酸化的代偿性增加,导致细胞糖酵解水平降低[3-5]。寡霉素B作为ATP合酶的非选择性抑制剂,在心肌缺血时有效减缓ATP的消耗。寡霉素C是一种线粒体F1F0-ATP合成酶抑制剂,可诱导更敏感的细胞死亡,并将细胞死亡模式从凋亡转变为坏死。
Oligomycin诱导HepG2和R-HepG2细胞线粒体膜去极化和细胞色素c释放[5]。Oligomycin A(0-16 µM;12-48 h)促进HT29细胞存活和增殖[6]。100 ng/ml Oligomycin在A549细胞中可在1小时内完全抑制OXPHOS磷酸化活性,并刺激不同程度的糖酵解增益[7]。5 µg/ml寡霉素可抑制H+- ATP合酶F0部分,强烈抑制TNF诱导的Hela细胞细胞色素c的释放和凋亡[8]。寡霉素B(1 µM)诱导的血管舒张在SUR2(nl)中比在SUR2野生型动脉中减少39-61%[9]。
