Design of non-nucleoside inhibitors of HIV-1 reverse transcriptase with improved activity towards Tyr181Cys containing variants was pursued with the assistance of free energy perturbation (FEP) calculations. Optimization of the 4-R substituent in 1 led to ethyl and isopropyl analogs le and if with 1-7 nM potency towards both the wild-type virus and a Tyr181C variant. (C) 2012 Elsevier.Ltd.
