摘要
研究了N1-烃基-3'-肟基靛玉红的合成新方法.以靛玉红为起始原料,经N-烃基化、成肟反应选择性地得到单烃基化的N1-烃基-3'-肟靛玉红衍生物3a~3c.晶体结构测定证明所合成的N1-乙基-3'-肟基靛玉红(3b)以(3Z,3'E)构型存在.体外5种细胞株抗肿瘤活性筛选数据显示,化合物3a~3c都有抗肿瘤作用,其中,N1-乙基-3'-肟基靛玉红(3b)具有较强的抗肿瘤活性和较低的毒性.
A novel synthetic method of N1-alkylindirubin-3 -oxime (3a~3c) was explored using indirubin as the starting material,including N-alkylation and oximation.Crystal X-ray diffraction studies of N1-ethylindirubin-3 -oxime (3b) gave good support for the (3Z,3 E) structure.The anticancer activity of compounds 3a~3c was evaluated and compound 3b showed potent anticancer effect and low toxicity compared to other chemotherapy drugs.
