rotenone

Description: Rotenone is a potent botanical insecticide which acts as an inhibitor of mitochondrial electron transport chain complex I. It specifically inhibits NAD-linked substrate oxidation of NADH dehydrogenase with an EC50=10 pmol/mg. It is known that this interference of the electron transport chain occurs from complex I to ubiquinone, similarly to amytal. Studies indicate that Rotenone inhibits mammalian cell proliferation, via suppressing microtubule assembly by binding to tubulin. Rotenone can inhibit the effects of N-methyl-4-phenylpyridinium on mitochondrial swelling and cytochrome c release. Rotenone is an inhibitor of NDUFS.
