Electrons from are supplied to the reactions from a component between the substrate site and the rotenone-sensitive site of the NADH dehydrogenase. |

The high rate of respiration of C. albicans in the presence of inhibitors for three sites of electron transport in the conventional oxidative pathway, the inhibition of this respiration by SHAM and its loss by the absence of cytochrome b, indicate an alternate oxidative pathway in this organism which crosses the conventional one at cytochrome b. Usual concentrations of antimycin A, rotenone and EDTA, individually or in combination, reduced aerobic growth rate and cell yield of Candida albicans to about half its normal level and to about the levels of previously-described -negative, cytochrome-complete and aa3-deficient variants which were little affected by the inhibitors. |

Experiments on the inhibition of the -cytochrome c oxidoreductase activity of mixtures of Complexes I and III by rotenone and antimycin indicate that electron transfer between a unit of Complex I-Complex III and extra molecules of Complexes I or III does not contribute to the overall rate of cytochrome c reduction. 3.

In rat liver mitochondria treated with rotenone, N-ethylmaleimide or oligomycin the expected alkalinization caused by consumption for aerobic oxidation of ferrocyanide was delayed with respect to ferrocyanide oxidation, unless carbonyl p-trifluoromethoxyphenylhydrazone was present. 2. This shows that the ferricyanide formed accepts electrons passing through the protonmotive segments of the respiratory chain at the level of cytochrome c and/or redox components of the cytochrome b-c1 complex situated on the side of the antimycin-inhibition site. |

Results are interpreted to suggest that partial inhibition of cytochrome c oxidase activity can lead to the stimulation of mitochondrial H2O2 production in the housefly at site (s) other than NADH dehydrogenase and /cytochrome b region; a possible source may be glycerophosphate dehydrogenase. H2O2 release by mitochondria, inhibited with rotenone and antimycin A, was greatly increased upon supplementation with however, the further addition of KCN or myxothiazol, to such preparations, caused a depression of H2O2 generation. |

The inhibition of the - oxydoreductase activity as well as the suppression of the -induced reduction of all cytochromes on the one hand and the insensitivity of the -ferricyanide oxydoreductase system on the other argue in favour of a site of action similar to rotenone. The partial suppression of the -induced reduction of cytochrome b with simultaneous complete inhibition of the reduction of the other cytochromes indicate an additional site of action analogous to antimycin A. |

The hypothesis that these effects are selectively linked to inhibition of the electron transport from cytochrome b to cytochrome c1 is validated by the following observations: (1) two complex III inhibitors, antimycin A and 2-heptyl-4-hydroxyquinoline N-oxide, enhanced the tB-OOH-induced DNA cleavage over the same concentration range as that in which inhibition of consumption was observed; (2) the complex III inhibitor-mediated enhancement of tB-OOH-induced DNA damage was abolished by the complex I inhibitor rotenone or by omission, and (3) the enhancing effects of antimycin A were not observed in respiration-deficient cells. |

1567448 | Unnikrishnan LS, Raj RK: This activity is sensitive to rotenone, antimycin A and o- diphenyl. The reductase system consisting of NADH-coenzyme Q reductase, cytochrome b like component (s) and succinate dehydrogenase/ reductase is thus very important and hence specific inhibitors of the system may prove useful in the effective control of filariasis. |

J Pharmacobiodyn. 1985 Dec;8(12):1006-17. These facts and results of inhibitor analysis suggest that the action site of CV-2619 is -linked complex I in the mitochondrial respiratory chain and is different from that of inhibitors of oxidative phosphorylation such as rotenone, oligomycin and 2,4-dinitrophenol. Reduced CV-2619 (2H-CV-2619) was rapidly oxidized through the cytochrome b chain, indicating that the compound functioned simply as an electron carrier of mitochondrial respiratory system. |
