A series of 4-hydroxycoumarin derivatives was prepared and evaluated for antitumor activity. The key fragments were 2a-c, 5c, 12b, 13b, 17, and 18 which were prepared via dianion ring cyclization, Friedel-Crafts acylation, and Reformatsky reaction. Compound 20b showed the most potent antitumor activity among the total 12 derivatives and compounds 19a and 19b exhibited efficacy comparable to etoposide
制备了一系列4-羟基香豆素衍生物,并评估了其抗肿瘤活性。关键片段是2a-c,5c,12b,13b,17和18,它们是通过二价环环化,Friedel-Crafts酰化和Reformatsky反应制备的。在全部12种衍生物中,化合物20b显示出最有效的抗肿瘤活性,并且化合物19a和19b显示出与依托泊苷体外抗肿瘤活性相当的功效。
