1 On the other hand, recombinant CYP3A4 and CYP1A2 as well as CYP1A1 and CYP2D6 in microsomes from baculovirus-infected insect cells were active in azelastine N-demethylation. azelastine cytochrome P450 family 3 subfamily A member 4 Homo sapiens
2 Summarizing the results, azelastine N-demethylation in humans liver microsomes is catalyzed mainly by CYP3A4 and CYP2D6, and CYP1A2 to a small extent (in average, 76.6, 21.8, and 3.9%, respectively), although the percent contribution of each isoform varied among individuals. azelastine cytochrome P450 family 3 subfamily A member 4 Homo sapiens
