“Halothane, isoflurane and sevoflurane dose‐dependently inhibited NADH :DBQ oxidoreductase activity.”
“Unlike the classical inhibitor rotenone, none of the anaesthetics completely inhibited enzyme activity at high concentration, suggesting that these agents bind weakly to the ‘hydrophobic inhibitory site’ of complex I. In conclusion, halothane, isoflurane and sevoflurane inhibit complex I ( NADH :ubiquinone oxidoreductase) of the electron transport chain.”
