A small library of 1,3-diarylpropenones was designed and synthesized as dual inhibitors of both HIV-1 reverse transcriptase (RT) DNA polymerase (DP) and ribonuclease H (RNase H) associated functions. Compounds were assayed on these enzyme activities, which highlighted dual inhibition properties in the low-micromolar range. Interestingly, mutations in the non-nucleoside RT inhibitor binding pocket strongly affected RNase H inhibition by the propenone derivatives without decreasing their capacity to inhibit DP activity, which suggests long-range RT structural effects. Biochemical and computational studies indicated that the propenone derivatives bind two different interdependent allosteric pockets.
