Abstract: Nitroaromatic compounds were reductively metabolized to the corresponding amine compounds via the intermediate hydroxylamines by liver microsomes from pig, rat, chook, cattle, sheep, paralichthys olivaceus and cyprinoid in varied reactivity. Toward the 4-nitro-1,2-dicyanbenzen substrate 1a, the pig, rat and sheep livers exhibited the higher reactivity, and the cyprinoid was inefficient for the reduction. Contrasted to 1a, it was difficult to reduce the monocyannitrobenzene 2a by pig liver. Compared with the baker’s yeast and grape cells, the liver microsomes exhibited higher reactivity toward the hydroxylamines.
