Abstract

A series of CR2(OH)-diarylpyrimidine derivatives (CR2(OH)-DAPYs) featuring a hydrophobic group at CH(OH) linker between wing I and the central pyrimidine were synthesized and evaluated for their anti-HIV activity in MT-4 cell cultures. All the target compounds except for compound 3k displayed inhibitory activity against HIV-1 wild-type with EC50 values ranging from 7.21±1.99 to 0.067±0.006 μM. Among them, compound 3d showed the most potent anti-HIV-1 activity (EC50=0.067±0.006 μM, SI>592), which was approximately 2-fold more potent than the reference drugs nevirapine (NVP) and delaviridine (DLV) in the same assay. In addition, the binding modes with HIV-1 RT and the preliminary SAR studies of these new derivatives were also investigated.
