8307034 Friedrich T, van Heek P, Leif H, Ohnishi T, Forche E, Kunze B, Jansen R, Trowitzsch-Kienast W, Hofle G, Reichenbach H, et al.: Two binding sites of inhibitors in NADH: ubiquinone oxidoreductase (complex I). Eur J Biochem. 1994 Jan 15;219(1-2):691-8.

The effect of ten naturally occurring and two synthetic inhibitors of NADH:ubiquinone oxidoreductase (complex I) of bovine heart, Neurospora crassa and Escherichia coli and glucose:ubiquinone oxidoreductase (glucose dehydrogenase) of Gluconobacter oxidans was investigated.
Class II inhibitors including the naturally occurring rotenone, phenoxan, aureothin and the synthetic benzimidazole inhibit complex I from all species in an non-competitive manner, but have no effect on the glucose dehydrogenase.

The role of glucose-6-phosphate dehydrogenase-derived NADPH..
O (2)(-) levels were elevated (70-90%; P < 0.05) in the diabetic heart, and this elevation was blocked by the Nox inhibitor gp-91 (ds-tat) (50 microM) or by the mitochondrial respiratory chain inhibitors antimycin (10 microM) and rotenone (50 microM).

Furthermore, inhibition of mitochondrial oxidation and fatty acid synthesis in small cells by rotenone led to a secondary inhibition of pentose shunt activity indicating a link between these two pathways.

The results confirm the effects of AMD on complex I and permit the placing of this drug in class A of the classification of Knobeloch, together with rotenone, amytal and chaotropic agents.

O2- production in J774.16 cells was inhibited by some agents known to block mitochondrial electron transport before coenzyme Q, such as rotenone and tetrathiafulvalene, whereas antimycin A enhanced O2- production.
