The present invention relates to an andrographolide derivative of the formula (I), wherein R1, R2 and R3 are same or different substituents selected from hydrogen, substituted or unsubstituted organic acid radicals, inorganic acid radicals, alkyl, aryl or heteroaryl, and at least one of R1, R2 and R3 is R-lipoic acid, S-lipoic acid or a mixture thereof, or corresponding dihydrolipoic acids thereof, or N-acetylcysteine radical. The derivative has good antitumor effect, can induce apoptosis of tumor cells, can directly kill Gram-positive bacteria (staphylococcus aureus) and drug resistance bacteria (MRSA5676 and MRSA5677), can inhibit the QS-system of Gram-negative bacteria (Pseudomonas aeruginosa), can inhibit and destroy the formation of biofilm of Pseudomonas aeruginosa; and exhibits significant hypoglycemic effect, so that it can be used in manufacture of medicaments for treatment of cancers, inflammation, diabetes, and bacterial and viral infections.
本发明涉及一种公式(I)的andrographolide衍生物,其中R1、R2和R3是相同或不同的取代基,选自氢、取代或未取代的有机酸基团、无机酸基团、烷基、芳基或杂环芳基,且R1、R2和R3中至少有一个是R-硫辛酸、S-硫辛酸或二者的混合物,或相应的二氢硫辛酸,或N-乙酰半胱氨酸基团。该衍生物具有良好的抗肿瘤效果,可以诱导肿瘤细胞凋亡,可以直接杀死革兰氏阳性细菌(金黄色葡萄球菌)和耐药细菌(MRSA5676和MRSA5677),可以抑制革兰氏阴性细菌(铜绿假单胞菌)的QS系统,可以抑制和破坏铜绿假单胞菌生物膜的形成;并且具有显著的降糖作用,因此可以用于制造用于治疗癌症、炎症、糖尿病以及细菌和病毒感染的药物。
