Electrophilic alkylation of colchicine at C(4) was accomplished by a multicomponent aromatic electrophilic substitution reaction with electrophilic aldehydes and carboxylic acids or amides in H2SO4. A series of new derivatives were obtained and evaluated for their antiproliferative effect towards various tumor cell lines, and their stimulatory effect on the development of polarity in human neutrophils
秋水仙碱在C(4)的亲电烷基化是通过与H 2 SO 4中的亲电子醛和羧酸或酰胺进行的多组分芳香族亲电取代反应完成的。获得了一系列新的衍生物,并评估了它们对多种肿瘤细胞系的抗增殖作用,以及它们对人类嗜中性粒细胞极性发展的刺激作用。
