A series of new 5H-indolo[2,3-b]quinoline derivatives bearing methoxy and methyl groups at C-2 and C-9 was synthesized (according to the modified Graebe-Ullmann reaction). These compounds were evaluated for their antimicrobial and cytotoxic activity and tested as inhibitors of DNA topoisomerase II. Lipophilic and calf thymus DNA binding properties of these compounds were also established. In the SAR
合成了一系列新的5H-吲哚并[2,3-b]喹啉衍生物,它们在C-2和C-9处带有甲氧基和甲基(根据改进的Graebe-Ullmann反应)。对这些化合物的抗微生物和细胞毒性活性进行了评估,并作为DNA拓扑异构酶II的抑制剂进行了测试。还确定了这些化合物的亲脂性和小牛胸腺DNA结合特性。在SAR研究中,我们使用了量子力学方法来分析药物的分子特性。发现所有测试的5H-吲哚并[2,3-b]喹啉在MIC为2.0至6.0 microM时均能抑制革兰氏阳性细菌和致病真菌的生长。他们还显示了针对几种不同来源的人类癌细胞系(ID50在0.6至1.4 microM之间变化)的体外细胞毒活性,并以0.2至0.5 microM的浓度刺激拓扑异构酶II介导的pSP65 DNA切割的形成。对DNA Tm的增加贡献最大的最活跃的吲哚[2,3-b]喹啉也显示出最高的DNA结合常数和最高的细胞毒活性。DNA结合特性和细胞
