Phenacetin 148-158 cytochrome P450, family 1, subfamily a, polypeptide 1 Rattus norvegicus 132-138 15231049-2 2004 Using rat cDNA-expressed cytochrome P450 (CYP) enzymes, we found that phenacetin biotransformation was primarily mediated by CYP2C6 and CYP1A isoforms, while chlorzoxazone biotransformation was largely mediated by CYP2E1 and CYP1A1. Phenacetin 70-80 cytochrome P450, family 1, subfamily a, polypeptide 1 Rattus norvegicus 225-231 2306261-4 1990 Studies with the reconstituted enzymes have shown that both forms of P450 catalyse phenacetin O-deethylation at rates that exceeded that of the high affinity component of activity of hepatic microsomal preparations from 3-methylcholanthrene-treated rats (at 4 microM phenacetin: P450c, 440 +/- 40 pmol/nmol/min; P450d, 1030 +/- 10 pmol/nmol/min; microsomal fraction, 163 pmol/mg/min). Phenacetin 83-93 cytochrome P450, family 1, subfamily a, polypeptide 1 Rattus norvegicus 279-284 3729972-3 1986 Microsomal monooxygenase heterogeneity is also shown to provide a plausible explanation of other published results signifying the departure of chloramphenicol and phenacetin from the concept of competitive inhibition despite competition with substrate for the active-site haem group of cytochrome P-450. Phenacetin 163-173 cytochrome P450, family 1, subfamily a, polypeptide 1 Rattus norvegicus 0-24 11765139-2 2001 The inhibition of recombinant CYP1A1 and CYP1A2 activity by quinidine and quinine was evluated using ethoxyresorutin O-deethylation, phenacetin O-deethylation and propranolol desisopropylation as probe catalytic pathways.
