to the non-substituted 2,4-diaryl-5H-indeno[1,2-b]pyridines. Compounds (2, 3, 4, 5, 8, and 9) with meta or para hydroxyl group on 2 or 4-phenyl ring have enhanced topo I and II inhibitory activity and cytotoxicity. However, additional substitution of chlorine group on furyl or thienyl ring (11, 12, 14, 16–18) generally reduced topo I and II inhibitory activity but improved cytotoxicity. The observation
作为开发新型抗癌剂的正在进行研究的一部分,设计了一系列修饰的2,4-二芳基-5 H-茚并[1,2- b ]吡啶,并通过引入羟基和氯部分进行合成。对它们的拓扑异构酶抑制活性和针对HCT15,T47D和HeLa癌细胞系的细胞毒性进行了评估。这种修饰使我们能够证明有关非取代的2,4-二芳基-5 H-茚并[1,2- b ]吡啶的结构-活性关系(SAR)研究。化合物(2,3,4,5,8,和9)与间位或对位2或4-苯环上的羟基具有增强的topo I和II抑制活性和细胞毒性。然而,呋喃基或噻吩环(氯基的额外替代11,12,14,16-18)通常会降低拓扑异构酶I和II的抑制活性,但改善的细胞毒性。根据羟基和氯基的位置观察细胞毒性和进行SAR研究,将为进一步研究具有相关支架的新型抗癌药提供有价值的见识。
