Novel 6-substituted-4-cycloalkyloxy-pyridin-2(1H)-ones were synthesized as non-nucleosidereversetranscriptaseinhibitors (NNRTIs), and their biological activity was evaluated. Most of the compounds, especially 26 and 22, bearing a 3-isopropyl and 3-iodine group, respectively, exhibited highly potent activity against wild-type HIV-1 strains and those resistant to reversetranscriptaseinhibitors (RTIs)
The trans-(S, S)-enantiomer 2e turned out to be significantly more potent than its enantiomer 2d against wild-type and mutant strains with high selectivity indexes.
