Novel N1-substituted 1,3-dihydro-2H-benzimidazol-2-ones as potent non-nucleoside reverse transcriptase inhibitors

Bioorg Med Chem. 2008 Aug 1;16(15):7429-35. doi: 10.1016/j.bmc.2008.06.012. Epub 2008 Jun 13.

Abstract

Several N(1)-substituted 1,3-dihydro-2H-benzimidazol-2-ones were synthesized and evaluated as anti-HIV agents. Some of them proved to be highly effective in inhibiting HIV-1 replication at nanomolar concentration as potent non-nucleoside HIV-1 RT inhibitors (NNRTIs) with low cytotoxicity. SAR studies highlighted that the nature of the substituents at N(1) and on the benzene ring of benzimidazolone moiety significantly influenced the anti-HIV activity of this class of potent antiretroviral agents.
