Biological Activity

ATP synthase [1]
(Cell-free assay)
In vitro

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. [1] 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] Oligomycin inhibits mitochondrial respiration in melanoma, sensitizes melanoma cells to therapy, blocks the emergence of the slow-cycling, long-term tumor-maintaining melanoma cells. [4]

PubMed: 27708226     

Western blot analysis of the GCN2-eIF2α-ATF4-xCT pathway in the SC-M1 cells under oligomycin (O, 1 μg/ml) and N-acetyl cysteine (NAC, N, 5 mM) treatments for 24 h. The immunoblot values were normalized to α-tubulin.

Western blot for Hsp90 client proteins (pAkt, Her2, and Raf) and Hsp70, Hsp90, and F1F0 ATP synthase using MCF7 cell lysates after 24 or 48 h of incubation with the indicated amount of vehicle (0.25% DMSO) or oligomycin A. The calculated EC50 value of oligomycin A against the MCF7 cell line was 7.35 μM.

  • Concentrations: 100 ng/ml
  • Incubation Time: 1 h
  • 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.
