of drug resistance. Previously we have reported that heteroarene-fused anthraquinones fused to a 5-membered heterocyclic ring are advantageous in killing drug resistant tumor cells. Herein we present the synthesis and antitumor properties of a series of new anthra[2,3-b]furan-2-carboxamides. Vast majority of new derivatives were similarly cytotoxic to wild type tumor cell lines and their isogenic sublines

heteroarene-fused anthraquinones, we herein demonstrate that derivative of anthra[2,3-b]thiophene-2-carboxamide, (compound 8) is highly potent against a panel of human tumor cell lines and their drug resistant variants. Treatment with submicromolar or low micromolar concentrations of 8 for only 30 min was sufficient to trigger lethal damage of K562 chronic myelogenous leukemia cells. Compound 8 (2.5 μM, 3–6 h)
蒽醌支架长期以来一直被认为是有效抗肿瘤药物的来源。特别是,该支架中侧链的各种化学修饰产生了对野生型肿瘤细胞有效的化合物,它们的对应物具有改变药物反应的分子决定因素,以及体内环境。进一步探索抗癌杂芳烃稠合蒽醌的化学型,我们在此证明蒽[2,3 - b ]噻吩-2-甲酰胺衍生物(化合物8)对一组人类肿瘤细胞系及其耐药性非常有效变种。用亚微摩尔或低微摩尔浓度8 处理仅 30 分钟就足以引发 K562 慢性粒细胞白血病细胞的致死性损伤。化合物8(2.5 μM,3-6 小时)诱导了细胞凋亡,这取决于半胱天冬酶 3 和 9 的伴随激活、聚(ADP-核糖)聚合酶的裂解、膜联蛋白 V/碘化丙啶双染色细胞的增加、DNA 片段化(subG1 分数) 和线粒体膜电位的降低。在无细胞系统中,既不能检测到与双链 DNA 的显着相互作用,也不能检测到 DNA 依赖性酶拓扑异构酶 1 by 8 的强烈抑制。激光扫描共聚焦显微镜显示,大约有8加入细胞后
