为了提高大豆苷元的生物利用度以改善其抗肿瘤等生物活性,利用前药原理对大豆苷元进行化学修饰。本文根据前药原理设计合成了2个新型大豆苷元磺酸酯衍生物(4~5)。所有化合物的结构均经IR、MS、元素分析和1H NMR确证。
In order to improve bioavailability and anticancer activity of daidzein,we designed and synthe-sized the new daidzein derivatives(4~5) according to principles of pro-drugs.Their structures were characterized by IR,MS,elemental analysis and 1H NMR spectral date.
