12-Hydroxynevirapine

12-Hydroxynevirapine (12-hydroxy-NVP; 12-OH-NVP) is a major oxidative metabolite of Nevirapine (HY-10570). Nevirapine is a non-nucleoside reverse transcriptase inhibitor indicated for the HIV-1 infections. Nevirapine causes idiosyncratic hepatotoxicity and mild-to-severe skin rashes. 12-Hydroxynevirapine, a non-reactive metabolite, can be bioactivated by sulphotransferases (SULTs) in the liver and skin, yielding the reactive species 12-Sulphoxy-nevirapine.
