Mephenytoin 109-122 cytochrome P450 family 3 subfamily A member 4 Homo sapiens 30-36 12900870-2 2003 Mephenytoin (MEPH), dextromethorphan, diclofenac, caffeine, and methadone (MET) were successfully applied as test substrates for CYP2C19, CYP2D6*1, CYP2C9*1, CYP1A2, and CYP3A4, respectively. Mephenytoin 0-11 cytochrome P450 family 3 subfamily A member 4 Homo sapiens 170-176 15499174-1 2004 Metabolic capacities for debrisoquin, sparteine, mephenytoin, nifedipine, and midazolam, which are substrates of polymorphic CYP2D6, CYP2C19, and CYP3A, have been reported to exhibit, in many cases, remarkable interindividual and ethnic differences. Mephenytoin 49-60 cytochrome P450 family 3 subfamily A member 4 Homo sapiens 146-151 10647906-4 1999 Methylenedioxyphenyl compounds which possess a bulky structure such as 1,4-benzothiazine showed substantial inhibition of S-warfarin 7-hydroxylation catalysed by CYP2C9, S-mephenytoin 4"-hydroxylation by CYP2C19, bufuralol 1"-hydroxylation by CYP2D6, and testosterone 6beta-hydroxylation by CYP3A4. Mephenytoin 170-183 cytochrome P450 family 3 subfamily A member 4 Homo sapiens 291-297 7581498-5 1995 We have used mephenytoin, debrisoquine and dapsone as selective probes for the phenotypic measures of activity of CYP2C19, CYP2D6, and CYP3A4, respectively. Mephenytoin 13-24 cytochrome P450 family 3 subfamily A member 4 Homo sapiens 135-141 8820421-4 1996 Ketoconazole and troleandomycin, both selective inhibitors for cytochrome P450 3A4 (CYP3A4), markedly inhibited the formation of all oxidative metabolites of MK-639; whereas other inhibitors (furafylline, sulfaphenazole, quinidine, S-mephenytoin, and diethyldithiocarbamate) had little effect on MK-639 metabolism. Mephenytoin 232-245 cytochrome P450 family 3 subfamily A member 4 Homo sapiens 63-82 8820421-4 1996 Ketoconazole and troleandomycin, both selective inhibitors for cytochrome P450 3A4 (CYP3A4), markedly inhibited the formation of all oxidative metabolites of MK-639; whereas other inhibitors (furafylline, sulfaphenazole, quinidine, S-mephenytoin, and diethyldithiocarbamate) had little effect on MK-639 metabolism. Mephenytoin 232-245 cytochrome P450 family 3 subfamily A member 4 Homo sapiens 84-90 9732386-5 1998 CYP2B6 levels were found to significantly (P < .0001) correlate with S-mephenytoin N-demethylation to nirvanol (r2 = 0.89), 7-hydroxy-4-trifluoromethylcoumarin formation (r2 = 0.81) and several markers of CYP3A levels and activity. Mephenytoin 72-85 cytochrome P450 family 3 subfamily A member 4 Homo sapiens 208-213 9357389-10 1997 We concluded that CYP3A4 catalyzes the sulfoxidation of omeprazole and that this is the predominant metabolic pathway of omeprazole in poor metabolizers of S-mephenytoin. Mephenytoin 156-169 cytochrome P450 family 3 subfamily A member 4 Homo sapiens 18-24 8548776-5 1996 The formation of hydroxydocetaxel was strongly reduced by CYP3A inhibitors such as ketoconazole, midazolam, erythromycin, testosterone, orphenadrine, and troleandomycin, whereas quinidine (CYP2D6), hexobarbital, tolbutamide, and mephenytoin (CYP2C) had no or little effect.
