Novel carbazole aminoalcohols were designed and synthesized as anticancer agents. Among them, alkylamine-chain-substituted compounds showed the most promising antiproliferative activity, with IC 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 indicate that the representative compounds may act as topo I poisons, causing single-strand DNA damage by stabilizing the topo I-DNA cleavage complex. In particular, the most potent compound, 1-(butylamino)-3-(3,6-dichloro-9H-carbazol-9-yl)propan-2-ol (6), was shown to be able to induce G -phase cell-cycle arrest and apoptosis in HeLa cells.
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表现出最有前景的抗增殖活性，对两种人类肿瘤细胞系的IC值在个位数微摩尔范围内。拓扑异构酶 I（topo I）可能是这些化合物的靶点之一。彗星试验和分子对接结果表明，代表性化合物可能作为topo I毒药，通过稳定topo I-DNA裂解复合物导致单链DNA损伤。特别是，最有效的化合物1-(丁基氨基)-3-(3,6-二氯-9H-咔唑-9-基)丙-2-醇（6）被证明能够诱导HeLa细胞的G期细胞周期停滞和凋亡。
