Abstract
We designed and synthesized 21 new indolylarylsulfones (IASs) as new HIV-1 NNRTIs. Among these, IAS 12 exhibited a remarkable antiviral activity against single and double mutants (K103N EC50 = <0.7 nM; Y181C EC50 = <0.7 nM; Y188L EC50 = 21.3 nM; K103N–Y181C EC50 = 6.2 nM), resulting equally or more active than previuosly reported IAS 6 and some approved anti-HIV-1 drugs. Docking and molecular dynamics simulations of compound 12 in complex with WT, Y181C, Y188L, K103N and K103N–Y181C RTs clarified a general binding mode that was consistent with biological results. Kinetic experiments disclosed that derivative 12 preferentially binds WT and K103N–Y181C RTs to binary and ternary complexes, respectively.
