Abstract
Rat liver microsomes attached to nanoparticles were used for LC-MS studies of CYP3A and 2E1 enzymes in metabolism of N -nitro so compounds.Using these biocolloids,turnover rates were measured within 2 min. Inhibitor IC 50 values for ketoconazole(KET) and 4-methylpyrazoie (4-MEP) were estimated.
