products. The molecular docking of the designed compounds indicated that they bind to the colchicin binding site of tubulin. They were synthesized by a unique iodine catalysed oxidative ring opening reaction of 1-aryltetrahydro-β-carbolines. Among the compounds synthesized quite a few compounds induced cytotoxicity on the cancer cells by disrupting the tubulin polymerization. They were found to be non-toxic
设计,合成并筛选了具有抗有丝分裂特性的,具有C2取代色胺(基于不同的C2-芳酰基/芳基吲哚和吲哚-二酮哌嗪杂种)的新型文库,针对其对微管蛋白聚合以及对A549肺癌HeLa的抑制作用子宫颈癌,MCF7乳腺癌和HePG2肝癌细胞系。分子的设计灵感来自已知的抗有丝分裂化合物和天然产物。设计化合物的分子对接表明它们与微管蛋白的秋水仙素结合位点结合。它们是通过独特的碘催化1-芳基四氢-β-咔啉的氧化开环反应合成的。在合成的化合物中,相当多的化合物通过破坏微管蛋白聚合来诱导癌细胞的细胞毒性。发现它们对健康细胞无毒。针对A549和HeLa细胞的最具活性的分子(浓度约6μM之间)的免疫荧光研究表明,微管结构完全被破坏和收缩。这些化合物还以低微摩尔IC50抑制吲哚胺2,3-二加氧酶。
