carbonyl linker between the central pyrimidine core and phenyl type B-arm, a series of (2,6-difluorophenyl)(2-(phenylamino)pyrimidin-4-yl)methanones was designed, prepared and tested for their anti-HIV-1 activity. The carbonyl linker bearing B phenyl arm was successfully attached at both C-2 and C-4 positions of the central pyrimidine ring using a new synthetic approach. Further modifications of target
为了阐明在中央嘧啶核和苯基B-臂之间含有羰基连接基的二芳基嘧啶家族(DAPYs)中的结构-几何-活性关系,需要一系列(2,6-二氟苯基)(2-(苯基氨基)嘧啶-4-设计,制备和测试yl)甲烷的抗HIV-1活性。使用新的合成方法,带有B苯基臂的羰基连接基已成功连接到中央嘧啶环的C-2和C-4位置。目标化合物的进一步修饰存在于嘧啶环的C-5位。体外在一系列22种化合物上进行的抗HIV-1活性研究证实了苯基B臂与通过羰基桥连接的嘧啶核之间的构象刚性以及苯基B的邻位上存在氟取代基的构象刚性至关重要部分。该系列中最有效的衍生物(化合物17)在两个由B芳族臂和嘧啶环制成的平面内具有几乎垂直的角度,显示出低纳摩尔抗HIV-1活性(EC 50 = 4 nM),无明显毒性(CC 50 > 57.1μM)。
