Upon co-treatment with 1-Aminobenzotriazole, the induction of CYP2B6 expressionby CITCO or
7、rifampin is potentiated: 12.6- and 4.0-fold for CITCO as well as 3.9- and 2.5-fold for rifampin. 1-Aminobenzotriazole has a greater potentiation effect on CITCO than on rifampin. 1-Aminobenzotriazole aloneincreases the expression levels of CYP3A4 in tow different hepatocytes (by 2.0- and 3.8-fold).
8、Upon co-treatment with1-Aminobenzotriazole, the effects of CITCO on CYP3A4 expression levels are potentiated by 3.8- and 6.0- fold ascompare to cells treated with CITCO alone1. 1-Aminobenzotriazole (ABT) (1 mM) shows pronounced (95%)inhibition of the formation of N-acetylprocainamide compare with th
