Structural Modifications of DAPY Analogues with Potent Anti‐HIV‐1 Activity

Abstract

A novel series of diarylpyrimidine analogues (DAPYs) featuring a naphthyl moiety at the C4 position were designed, with all compounds exhibiting strong activity against wild-type HIV-1.A novel series of diarylpyrimidine analogues (DAPYs) featuring a naphthyl moiety at the C4 position were synthesized and evaluated for their in vitro activity against HIV in MT-4 cells. All compounds exhibited strong activity against wild-type HIV-1. The most active compound showed activity against wild-type HIV-1 with an EC(50) value of 2.35 nM and against the double mutant strain (K103N+Y181C) with an EC(50) value of 6.6 microM, with a selectivity index greater than 60 000 against wild-type HIV-1. Additionally, some compounds also showed activity against HIV-2 (EC(50)=5.82 microM).
