Abstract

Here, we describe the design, synthesis, biological evaluation, and identification of a clinical candidate non-nucleoside Reverse Transcriptase inhibitors (NNRTIs) with a novel aryl-phospho-indole (APhI) scaffold. NNRTIs are recommended components of highly active antiretroviral therapy (HAART) for the treatment of HIV-1. Since a major problem associated with NNRTI treatment is the emergence of drug resistant virus, this work focused on optimization of the APhI against clinically relevant HIV-1 Y181C and K103N mutants and the Y181C/K103N double mutant. Optimization of the phosphinate aryl substituent led to the discovery of the 3-Me,5-acrylonitrile-phenyl analogue RP-13s (IDX899) having an EC50 of 11 nM against the Y181C/K103N double mutant.
