To improve the conformational flexibility and positional adaptability of the traditional diarylpyrimidines (DAPYs), a family of diarylpyrimidines featuring a C-N diatomic linker between the left wing benzene ring and the central pyrimidine was firstly designed, synthesized, and evaluated for in vitro anti-HIV activity. Most of target molecules showed excellent activities against wild-type (WT) HIV-1. Among them the most potent two compounds 12h and 12r displayed extremely potent WT HIV-1 inhibitory activities with an EC50 of 2.6nM and 3.0nM, respectively, while their selective index (CC50/EC50) values were both over 1000. Another compound 12b (EC50 14.9nM) was also noteworthy due to its high SI of 18,614. Moreover, all of compounds were evaluated for their WT HIV-1 reverse transcriptase activities, which shown that the newly synthesized CH2NH-DAPYs bind to HIV-1 RT and belong to the genuine NNRTIs. However, the synthesized compounds lack the activities against HIV-1 double mutant (RES056) and HIV-2 (ROD). Thus it is an upcoming objective to improve the activities against HIV-1 double mutants.
