三萜类化合物抗病毒的构效关系及其作用机制研究进展

Triterpenoids are widely present in nature and have received wide attention because of their anti-tumor, anti-viral, antibacterial, anti-inflammatory and immunomodulatory pharmacological activities. The compounds such as oleanolic acid, ursolic acid, glycyrrhizic acid and betulinic acid in natural triterpenes all showed good anti-viral activity. This review summarizes the advances of triterpenoids and their derivatives exemplified by tetracyclic triterpenes and pentacyclic triterpenes, and focusses on the structure-activity relationships and mechanisms of anti-HIV, anti-influenza, anti-coronavirus and anti-HBV/HCV. Thus, it would provide clues for rational design and development of novel anti-viral agents for the future.
