Cumene hydroperoxide-supported denitrification of 2-nitropropane in uninduced mouse liver microsomes.

Cumene hydroperoxide supported oxidative denitrification of 2-nitropropane was investigated in uninduced mouse liver microsomes. The cytochrome P-450 peroxygenase catalyzed reaction resulted in the production of nitrite and acetone. Several lines of evidence suggested the involvement of multiple forms of cytochrome P-450. Acetone production was at least two times greater than nitrite release possibly due to sequestration of nitrite in the reaction mixtures.
