Novel carbazole aminoalcohols were designed and synthesized as anticancer agents. Among them, alkylamine‐chain‐substituted compounds showed the most promising antiproliferative activity, with IC50 values in the single‐digit micromolar range against two human tumor cell lines. Topoisomerase I (topo I) is likely to be one of the targets of these compounds. Results of comet assays and molecular docking
设计并合成了新型咔唑氨基醇作为抗癌剂。其中,烷基胺链取代的化合物显示出最有希望的抗增殖活性,对两种人类肿瘤细胞系的IC 50值在个位数微摩尔范围内。拓扑异构酶I(拓扑I)可能是这些化合物的靶标之一。彗星分析和分子对接的结果表明,代表性化合物可能充当topo I毒物,通过稳定topo I–DNA裂解复合物而引起单链DNA损伤。特别是,最有效的化合物1-(丁基氨基)-3-(3,6-二氯-9 H-咔唑-9-基)丙烷-2-醇(6)被证明能够诱导G 2。HeLa细胞的阶段性细胞周期停滞和凋亡。
