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.
合成了一系列在机翼I和中央嘧啶之间的CH(OH)接头处具有疏水基团的CR 2(OH)-二芳基嘧啶衍生物(CR 2(OH)-DAPYs),并评估了它们在MT-中的抗HIV活性4细胞培养。除化合物3k外,所有目标化合物均显示出对HIV-1野生型的抑制活性,EC 50值为7.21±1.99至0.067±0.006μM。其中,化合物3d显示出最有效的抗HIV-1活性(EC 50 = 0.067±0.006μM,SI> 592),在同一试验中,其效力比参考药物奈韦拉平(NVP)和德拉维定(DLV)高约2倍。此外,还研究了与HIV-1 RT的结合模式以及这些新衍生物的初步SAR研究。
