Rotenone
Description
(2R,6aS,12aS)-1,2,6,6a,12,12a-hexahydro-2-isopropenyl-8,9 dimethoxychromeno[3,4-b]furo(2,3-h)chromen-6-on; C23H22O6. Inhibitor of complex I via inhibition of NADH oxidation.It inhibits the transfer of electrons from iron-sulfur centers in CI to ubiquinone via binding to the ubiquinone binding site of CI. See also S(Rot).

Application in HRR
Rot: Rotenone (Rotenone ≥95%, C23H22O6); Sigma R 8875, 1 g, store at R.T.: FW = 394.42)
Caution: Very toxic and light sensitive (store solution in a dark glass vial).
Preparation of 0.1 mM Rotenone solution (dissolved in 99.9% Ethanol):
- 1) weigh 0.39 mg of Rotenone directly into a dark glass vial
- 2) add 10 ml Ethanol
- 3) store frozen at -20 °C
