Abstract

Monte Carlo simulations using free energy perturbation theory have been used to guide the selection of bicyclic heterocycles in the lead optimization of non-nucleoside inhibitors of HIV-1 reverse transcriptase (NNRTIs). Good correlation is found between predicted and observed activities. Six compounds are reported with EC50 values below 20 nM for protection of human MT-2 cells against the cytopathogenicity of HIV-1. Striking variation in activity is found and analyzed for an isomeric pyrrolopyrimidine and pyrrolopyrazine pair.
