characterized by a halogen atom on the methylene linker between wing I and the central pyrimidine ring was synthesized and evaluated for their anti-HIV activity in MT-4 cell cultures. The two most promising compounds 7f and 7g showed excellent activity against wild-type HIV-1 with low nanomolar EC50 values of 0.005 and 0.009 μM, respectively, which were comparable to or more potent than all the reference
合成了一系列新的二芳基嘧啶(DAPYs),其特征是在机翼I和中央嘧啶环之间的亚甲基连接基上具有卤素原子,并评估了它们在MT-4细胞培养物中的抗HIV活性。两种最有希望的化合物7f和7g对野生型HIV-1表现出优异的活性,低纳摩尔EC 50值分别为0.005和0.009μM,与所有参比药物齐多夫定(AZT),拉米夫定相当或比其更有效(3TC),奈韦拉平(NEV),依非韦伦(EFV),德拉维定(DLV)和依曲韦林(ETV)。特别地,7g还对具有EC 50的双突变株103N + 181C表现出强大的活性。值为8.2μM。还研究了这一系列新的CHX-DAPYs的初步构效关系(SAR)和分子对接分析。
