Oligomycin A

Synonyms: MCH 32

Oligomycin A (MCH 32), a dominant analog of the isomers, is an inhibitor of mitochondrial F1FO ATP synthase which inhibits oxidative phosphorylation and all the ATP-dependent processes occurring on the coupling membrane of mitochondria. It inhibits ATP synthase by blocking its proton channel (Fo subunit), which is necessary for oxidative phosphorylation of ADP to ATP. It also induces apoptosis in a variety of cell types.

Oligomycin A is an inhibitor of ATP synthase, inhibits oxidative phosphorylation and all the ATP-dependent processes occurring on the coupling membrane of mitochondria.Oligomycin A inhibits ATP synthase by blocking its proton channel (Fo subunit), which is necessary for oxidative phosphorylation of ADP to ATP. The inhibition of ATP synthesis by oligomycin A will significantly reduce electron flow through the electron transport chain; however, electron flow is not stopped completely due to a process known as proton leak or mitochondrial uncoupling.

In a group of cancer cells, Oligomycin at 100 ng/ml completely inhibits oxidative phosphorylation activity in 1 h and induces various levels of glycolysis gains by 6 h. [2]

Oligomycin, inhibitor of the F0 part of H+-ATP-synthase, suppresses the TNF-induced apoptosis. [3]

Method

ATP and Oligomycin Dose-Response Growth Measurement. Cellular ATP changes are measured by CellTiter-Glo reagent. To measure oligomycin dose-response curves, the cells are plated in 96-well plates at about 400–500 cells/well in 100 μl of culture, dosed the next day, and grown for 4 additional days followed by assaying with Cell-Titer-Glo reagent. The dose-response curves are plotted with nonlinear regression analysis of GraphPad Prism.
