Mechanism of Action

Targets/IC₅₀/Ki	Reverse transcriptase
In vitro	Nevirapine (NSC 641530) is a non-nucleoside RT inhibitor with a well-characterized inhibitory activity on RT enzymes of retroviral origin. It is also an effective inhibitor of the endogenous RT in murine and human cell lines. This compound is a highly specific inhibitor of HIV-1 reverse transcriptase (RT) which exhibits an IC50 = 84 nM in enzyme assays and IC50 = 40nM against HIV-1 replication in cell culture. It alters the cleavage specificity of the RNase H, resulting in Nevirapine-induced stimulation of RNase H activity beyond the increase expected from the change in cleavage specificity. It is an inhibitor of only CYP3A4 at concentrations that are well above those of therapeutic relevance (Ki = 270 mM). Its exposure rescues the differentiation block present in acute myeloid leukemia (AML) cell lines and primary blasts from two AML patients, as indicated by morphological, functional and immunophenotypic assays.
In vivo	Nevirapine (NSC 641530) is metabolized to 4-CANVP as a major metabolite in all male animals and in female mice, dogs, and monkeys. 3-OHNVP is a major fecal metabolite in all animals except for the male rat. In the bile of rats, 4-CANVP is a major metabolite along with 12-OHNVP glucuronide.
