Abstract
The lucigenin luminescence elicited by rat liver microsomes and its modulation by the nitroazole compounds metronidazole and sanazole (drug AK- 2123), as well as the rates of lucigen-independent NADPH consumption and cytochrome c reduction, were studied. The obtained data suggest that the luminescence can be the result of univalent lucigenin reduction by microsomal NAD(P)H-reductases, generation of superoxide anion radical in the redox cycle of lucigenin radicals, dioxetane formation by (di)oxygenases, and catalytic action of cytochrome P450 heme on dioxetane decomposition, followed by light emission.
