Name: Oligomycin A (MCH 32)
SKU: S1478
Availability: InStock
Rating: 5 (110 reviews)

Cat.No.S1478

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.

FCCP

It inhibits ATP synthase and reduces OCR, whereas FCCP uncouples oxygen consumption from ATP production and raises OCR to a maximal value in SK-Mel-28 cells.

Mechanism of Action

Targets/IC₅₀/Ki	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.This compound 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 this chemical 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, this compound at 100 ng/ml completely inhibits oxidative phosphorylation activity in 1 h and induces various levels of glycolysis gains by 6 h. ^[2] This inhibitor, of the F0 part of H⁺-ATP-synthase, suppresses the TNF-induced apoptosis. ^[3] This chemical inhibits mitochondrial respiration in melanoma, sensitizes melanoma cells to therapy, blocks the emergence of the slow-cycling, long-term tumor-maintaining melanoma cells. ^[4]
In vivo	Oligomycin A (MCH 32) is an inhibitor of mitochondrial F0F1-ATPase.
