A comparison of the metabolism of midazolam in C57BL/6J and hepatic reductase null (HRN) mice.
Biochem. Pharmacol. 92(4) , 701-11, (2014) The hepatic cytochrome P450 reductase null (HRN) mouse, which has no functional hepatic Cyp P450s, may represent a useful model for examining extra-hepatic P450-related oxidative metabolism. Here the pharmacokinetics and metabolic fate of midazolam, a drug kn... |

Inhibition and kinetics of cytochrome P4503A activity in microsomes from rat, human, and cdna-expressed human cytochrome P450.
Drug Metab. Dispos. 24(9) , 940-7, (1996) Midazolam (MDZ) is metabolized in human liver microsomes by the cytochrome P450 (CYP) 3A subfamily to 1'-hydroxy (1'-OH) and 4-hydroxy (4-OH) metabolites. MDZ is metabolized in the rat primarily to 4-OH MDZ, 1'-OH MDZ, and 1',4-dihydroxy (1',4-diOH) MDZ. The ... |

Expression of the human CYP3A4 gene in the small intestine of transgenic mice: in vitro metabolism and pharmacokinetics of midazolam.
Drug Metab. Dispos. 31(5) , 548-58, (2003) Human cytochrome P450 3A4 (CYP3A4) is the most abundant hepatic and intestinal phase I drug-metabolizing enzyme, and participates in the oxidative metabolism of approximately 50% of drugs on the market. In the present study, a transgenic-CYP3A4 (Tg-CYP3A4) mo... |
