摘要:

拓扑异构酶I和拓扑异构酶II 双重抑制剂因为具有双靶点, 在提高抗增值活性的同时可以降低毒副作用。作者设计并合成了28个茚[1, 2-b]并吲哚衍生物类新型拓扑异构酶III抑制剂, 并发现化合物2-3j具有最强抗细胞增殖活, HCT-116细胞实验中IC50值为0.74 μM, 且可以诱导人直肠癌细胞凋亡。2-3j不仅对药物敏感细胞系有活性, 对于多重抗(MDR)细胞系K562/A02, MCF-7/AdrKB/Vcr细胞均有逆转抗药性作用, 逆转抗药性倍数变化分别为3.2, 10.15.82-3j的作用机理可能是通过抑制ABCG2活性, 提高药物细胞内浓度, 从而增强MDR细胞对传统化疗药物的敏感度。2-3j可以作为潜在的新型拓扑异构酶I & IIABCG2抑制剂先导化合物进行进一步开发和研究。

Abstract:

A single compound able to inhibit both Topo I and II may present the advantage of improving anti-proliferative activity, with reduced toxic side effects, with respect to the combination of two inhibitors. We designed and synthesized 28 compounds of indeno[1, 2-b]indole derivatives as a new class of Topo I and II inhibitor and successfully identified compound 2-3j, which showed the most potent cell growth inhibition with IC50 =0.74 μM against HCT-116 cell line. Compound 2-3j was also evaluated as a potent topoisomerase I and II inhibitor and can induce apoptosis in human colon cancer cells. 2-3j showed potency against a small panel of drug sensitive and multidrug resistant (MDR) cell lines, and it reversed the MDR of K562/A02, MCF-7/Adr, and KB/Vcr cells at 0.5 μM, with reversal fold values of 3.2, 10.1, and 5.8, respectively. 2-3j might inhibit the function of ABCG2 to increase intracellular drug accumulation and enhance the sensitivity of conventional chemotherapeutic agents for MDR cells. 2-3j could be a promising lead for the development of a new class of antitumor drug acting as inhibitors of Topo I & II and ABCG2.
