描述 | Nevirapine is a non-nucleoside inhibitor of HIV-1 reverse transcriptase used to treat and prevent HIV/AIDS; with a Ki of 270 μM. Nevirapine itself is an inhibitor of only CYP3A4 at concentrations that are well above those of therapeutic relevance (Ki=270 μM)[3]. At all doses (100, 200, 350, 500 μM) tested, nevirapine significantly inhibited cell proliferation after 48 h treatment. At high dose (500 μM), nevirapine significantly increased the percentage of apoptotic cells compared with control (P<0.01). At lower doses (200 μM and 350 μM), nevirapine did not induce cell apoptosis, but up-regulated NIS and THSR mRNA expression in a dose-dependent manner[4]. Nevirapine also has an important role in preventing mother-to-child transmission of HIV. Nevirapine interacts with cytochrome P450 enzymes both as a substrate and as an inducer[5]. Nevirapine (9 mg/kg, 18 mg/kg and 36 mg/kg) showed significant (P < 0.05) reduction in ulcer severity score and ulcer index as compared to the control in the models,.with corresponding increase in percentage inhibition[6]. Nevirapine inhibits replication of multiple HIV-1 strains and clinical isolates in cultured human T cells, but has no activity against other retroviral RTs (including HIV-2 RT) or endogenous human DNA polymerases[7]. |
