Imipramine 42-52 cytochrome P450 family 3 subfamily A member 4 Homo sapiens 110-115 15199661-1 2004 Tricyclic antidepressants are all hydroxylated by cytochrome P450 (CYP) 2D6, but the tertiary amines, amitriptyline, clomipramine and imipramine, are also N-demethylated to the active metabolites, nortriptyline, N-desmethylclomipramine and desipramine, by several CYPs, including the polymorphic CYP2C19, CYP1A2 and CYP3A4. Imipramine 134-144 cytochrome P450 family 3 subfamily A member 4 Homo sapiens 316-322 16141545-3 2005 Among the recombinant CYPs, CYP3A4 exhibited the highest metabolic activities of all compounds except for clotiazepam and imipramine. Imipramine 122-132 cytochrome P450 family 3 subfamily A member 4 Homo sapiens 28-34 9490065-8 1998 In fetuses and early neonates, CYP3A proteins were responsible for the low demethylation of imipramine (3-4% of the adult activity) before the onset of CYP1A2 and the subsequent rise of activity. Imipramine 92-102 cytochrome P450 family 3 subfamily A member 4 Homo sapiens 31-36 9505989-3 1997 Imipramine pharmacokinetics serve as a marker for hepatic CYP2D6, CYP1A2, CYP3A activity. Imipramine 0-10 cytochrome P450 family 3 subfamily A member 4 Homo sapiens 74-79 9278210-1 1997 AIMS: In vitro data indicate that imipramine (IMI), a widely used tricyclic antidepressant drug, is N-demethylated by several isoforms of cytochrome P450, which include CYP3A4. Imipramine 34-44 cytochrome P450 family 3 subfamily A member 4 Homo sapiens 169-175 9278210-1 1997 AIMS: In vitro data indicate that imipramine (IMI), a widely used tricyclic antidepressant drug, is N-demethylated by several isoforms of cytochrome P450, which include CYP3A4. Imipramine 46-49 cytochrome P450 family 3 subfamily A member 4 Homo sapiens 169-175 9088587-6 1997 CONCLUSIONS: These findings indicate that ketoconazole, a relatively specific inhibitor of CYP3A4, inhibits the N-demethylation of imipramine without affecting the 2-hydroxylation of imipramine and desipramine. Imipramine 131-141 cytochrome P450 family 3 subfamily A member 4 Homo sapiens 91-97 9084457-0 1997 Imipramine demethylation in vivo: impact of CYP1A2, CYP2C19, and CYP3A4. Imipramine 0-10 cytochrome P450 family 3 subfamily A member 4 Homo sapiens 65-71 9084457-2 1997 At least three different P450s appear to be responsible for the N-demethylation of imipramine to desipramine in vivo: CYP1A2, CYP2C19, and CYP3A4. Imipramine 83-93 cytochrome P450 family 3 subfamily A member 4 Homo sapiens 139-145
