Inhibition of nasal and liver cytochrome P-450 mono-oxygenases by dioxolanes.


1. A series of six alkyl-substituted dioxolanes were studied for their inhibitory effects on mono-oxygenase activities in vitro with nasal and hepatic microsomes from rats and rabbits. 2. Carbon monoxide binding and hexamethylphosphoramide (HMPA) N-demethylase activity were most susceptible to inhibition by the test compounds. 3. Inhibition of HMPA N… (More)
