One-pot, three components, conventional and microwave-assisted synthesis of bisindolyl analogs is described. Michael addition of preformed 2,5-disubstituted indole-3-carboxaldehydes and 3-methyl-1H-pyrazol-5(4H)-one with 2,5-disubstituted indoles under solvent and catalyst-free conditions afforded the hitherto unreported 2,5-disubstituted bisindolyl analogs bearing a pyrazolone moiety in excellent
描述了一锅,三组分,常规的和微波辅助的比邻吲哚基类似物的合成。在无溶剂和无催化剂条件下,将2,5,5-二取代的吲哚-3-甲醛和3-甲基-1H-吡唑-5(4H)-与2,5-二取代的吲哚进行迈克尔加成反应,迄今未报道2带有吡唑啉酮部分的,5-二取代的双吲哚基类似物,收率极高。使用IR,1 H NMR,质谱和分析数据对所有合成的化合物进行表征。筛选类似物进行体外细胞毒性和DNA切割研究。在筛选的化合物4c,4f和4h - 4j中已经成为最有效的细胞毒性药物,而4c和4f – 4h作为活性DNA裂解类似物出现。
