General description
Rotenone belongs to the retinoid family. It is naturally present in Leguminosa plants and is considered to be cytotoxic. It is commonly used as an insecticide and a pesticide.
Application
Rotenone has been used:
- to study its effect on cell proliferation
- to detect the production of cellular reactive oxygen species in isolated rat forebrain mitochondria
- to measure mitochondrial enzymatic activity
Biochem/physiol Actions
Inhibitor of mitochondrial electron transport.
Rotenone is an inhibitor of mitochondrial electron transport at nicotinamide adenine dinucleotide (NADH):ubiquinone oxidoreductase. It is readily absorbed through the exoskeletons of arthropods, but poorly absorbed cutaneously or from the gastrointestinal tract of mammals. Rotenone acts as a neurotoxic agent which can produce Parkinson-like condition to serve as an animal model for the study of etiology and interventions. The primary mechanism of action of rotenone is complex I inhibition, followed by the generation of oxidative stress and oxidative damage. Because rotenone is lipophilic, it readily penetrates the brain, where it attaches to and inhibits mitochondrial complex I of electron chain transport (ETC).
Preparation Note
This product is soluble in DMSO at 0.5 mg/ml. Other sources suggest it can be dissolved in DMSO up to 100 mM, however this has not been verified.

Can aliquots of rotenone resuspended in DMSO be stored at -20C?
1 answer-
The solution stability has not been determined. However, a similar product, 557368, notes that "following reconstitution, aliquot, flush with nitrogen, and store at -70°C. Stock solutions are stable for up to 1 month at -70°C".

What is the solubility in other compounds ?
1 answer-
This product is tested for solubility at 50 mg/mL in chloroform. Rotenone is poorly soluble in water at approximately 0.25-0.50 uM. Other options include Ethanol and DMSO.
Ethanol: 5 mg/mL (higher concentrations may be achieved with heat and sonication)
DMSO: 50 mg/mLHelpful?
