Biological Activity: 3-Hydroxyflunitrazepam (3-OH FNTZ) is the major metabolite of Flunitrazepam (FNTZ), generated via 3-hydroxylation by CYP3A4 (Km = 286 μM), and represents the dominant metabolic pathway (>80%) in liver microsomes. Its formation is significantly inhibited by CYP3A4 inhibitors such as Ketoconazole (HY-B0105) (IC50 = 0.11 μM) and Ritonavir (HY-90001) (IC50 = 0.041 μM), indicating a strong dependence on CYP3A4 activity and potential drug interactions[1].
