1,4-linked hybrids 28–31(a–c). From these results, a preliminary structure–activity relationship (SAR) was established, which enabled the design of novel 1,3-linked pyrimidine-quinolone hybrids (33–36)(a–c). Compounds 35(a–c), the most promising ones, were synthesized and evaluated, fitting the experimental results with the predictions from docking analysis. In this way, we obtained novel pyrimidine-quinolone
通过对接支架替代作为乳酸脱氢酶 A ( h LDHA) 抑制剂,设计了一系列新型嘧啶-喹诺酮杂化物。在计算机上研究了嘧啶和喹诺酮支架(10-21和24-31 )之间具有不同接头的结构,最终选择了具有 2-氨基苯硫醚( U形)和 4-氨基苯硫醚接头( 24-31 )的结构。这些新的嘧啶-喹诺酮杂化物 ( 24 – 31 )( a – c) 通过 3-(((2/4-氨基苯基)硫代)甲基)喹啉-2(1 H )-酮之间的绿色无催化剂微波辅助芳族亲核取代反应,很容易以良好到极好的收率合成22/23 ( a – c ) 和 4-aryl-2-chloropyrimidines ( 1 – 4 )。评估了合成杂交体对h LDHA 的抑制活性,得出U 形杂交体的IC 50值24 – 27 ( a – c ) 远好于 1,4-连锁杂交体的 IC 50 值28 – 31 ( a –三)。根据这些结果,建立了初步的构效关系
