隐丹参酮(CT)是丹参中主要的脂溶性活性成分, 具有心肌保护及抗氧化等作用. 为了改善其极性, 提高活性, 增加作用靶点, 将其与丹参中水溶性活性成分丹参酚酸及其类似物进行1位杂化合成. 共合成了42个衍生物, 均为新化合物. 与CT相比, 衍生物的极性得到了改善. 利用体外缺氧/复氧损伤(HRI)模型实验, 初步评价了衍生物的心肌保护作用. 结果表明, 与CT相比, 大部分衍生物心肌细胞保护作用增强, 其中有6个化合物作用显著. 利用Sirtuin 1 (SIRT1)高通量活性筛选平台和分子对接技术, 初步探索了活性衍生物可能的作用机制. 构效关系研究表明, 衍生物1位R构型的产物活性优于S构型的产物, 具有供电子取代基的芳香酸衍生物的活性优于具有吸电子取代基的芳香酸衍生物.

Cryptotanshinone (CT) is the major lipid-soluble component of Salvia miltiorrhiza, which has myocardial protection and antioxidant effects. To improve its polarity, activity and targets, CT was hybridized with salvianolic acids, the water-soluble active component in salvia miltiorrhiza, and its analogues at its 1 site. A total of 42 derivatives were synthesized, all of which are new compounds. Compared with CT, the polarities of the derivatives were improved. The cardioprotective effects of derivatives were preliminarily evaluated by hypoxia/reoxygenation injury (HRI) model in vitro. The results showed that the activities of most derivatives were enhanced compared with CT, and 6 compounds showed significant effects. Sirtuin 1 (SIRT1) high-throughput activity screening platform and molecular docking technology were used to explore the possible mechanism preliminarily. Structure-activity relationship studies showed that the product activity of 1-position R configuration was better than that of S-configuration, and the activity of aromatic acid derivatives with electron-donating substituents was better than that of with electron-absorbing substituents.
