Based on 1 Customer Validation
18α-Glycyrrhizic acid (18α-GA; Isoglycyrrhizinic acid; 18α-Glycyrrhizic acid) is a derivative of glycyrrhizic acid with oral activity. 18α-Glycyrrhizic acid exhibits antioxidant, anti-inflammatory, hepatoprotective and cardioprotective activities. 18α-Glycyrrhizic acid protects against ethanol-induced alcoholic liver disease in rats by upregulating the expression levels of SOD, GSH, PPAR-α and CPT-1. 18α-Glycyrrhizic acid shows cytotoxicity against T lymphocytes and inhibits HIV-1 replication in these cells. 18α-Glycyrrhizic acid alleviates oxidative stress by reducing the levels of ROS, Nrf2, HO-1 and p-P65, and alleviates pyroptosis by downregulating the expression levels of NLRP3, GSDMD-N, P20 and c-IL-1β. 18α-Glycyrrhizic acid inhibits autophagy, colonic fibrosis and myocardial fibrosis, and regulates intestinal barrier integrity. 18α-Glycyrrhizic acid can be used in research related to alcoholic liver disease, HIV-1 infection, hepatotoxicity, acute liver failure, inflammatory bowel disease and myocardial fibrosis.
