Oltipraz, an inhibitor of human immunodeficiency virus type 1 replication in vitro (ED50 approximately 10 microM), undergoes extensive metabolism in vivo. Most of the orally administered drug undergoes opening of the dithiolethione ring, reduction, recyclization, and methylation to form 7-methyl-6,8-bis(methylthio)pyrrolo[1,2-a]pyrazine ("metabolite III"). We report here that metabolite III inhibits viral replication in vitro (ED50 approximately 25 microM) in acutely infected H9 and CEM T cell… CONTINUE READING
