new series of indenoisoquinoline derivatives was designed and synthesized. The in vitro anti-proliferative activity of these novel compounds was evaluated in HepG2, A549 and HCT-116 cell lines. Compounds 9a, 9b, 10a, 10c, 10e, 18a and 18b manifested potent inhibitory activity against the three tested cancer cell lines. Nineteen compounds were also tested for Top I inhibition at 50 μM. Almost all the
设计并合成了一系列新的茚并异喹啉衍生物。在HepG2,A549和HCT-116细胞系中评估了这些新型化合物的体外抗增殖活性。化合物9a,9b,10a,10c,10e,18a和18b表现出对三种测试癌细胞系的有效抑制活性。还测试了19种化合物在50μM下对Top I的抑制作用。在该浓度下,几乎所有测试的化合物都显示出有效的Top I抑制活性。最有效的化合物9a和10a 与HCPT和TPT相比,它具有更高的细胞毒性,并且在我们的生物学分析中,对Top I的抑制活性可与CPT相媲美。
