Abstract

New indolylarylsulfone HIV-1 NNRTIs were synthesized to evaluate unexplored substitutions of the benzyl/phenylethyl group linked at the indole-2-carboxamide. Against the NL4-3 HIV-1 WT strain, 17 out 20 compounds were superior to NVP and EFV. Several compounds inhibited the K103N HIV-1 mutant strain at nanomolar concentration and were superior to EFV. Some derivatives were superior to EFV against the Y181C and L100I HIV-1 mutant strains. Against the NL4-3 HIV-1 strain, the enantiomers 24 and 25 showed small differences of activity. In contrast, 24 turned out significantly more potent than 25 against the whole panel of mutant HIV-1 strains. The docking studies suggested that the difference in the observed inhibitory activities of 24 and 25 against the K03N mutation could be due to a kinetic rather than affinity differences.
