Descriptions:
Astragaloside II can downregulate the expression of the P-gp and mdr1 gene, suppress phosphorylation of extracellular signal regulated kinase 1/2, p38 and c-Jun N-terminal kinase, suggests that Astragaloside II is a potent multidrug resistance (MDR) reversal agent and may be a potential adjunctive agent for hepatic cancer chemotherapy.[1]
Astragaloside II induces osteogenic activities of osteoblasts through the bone morphogenetic protein-2/MAPK and Smad1/5/8 pathways, it may become a novel candidate that is beneficial for stimulating the osteoblastic activity resulting in bone formation.[2]
Astragaloside II has immunomodulating activity, can trigger T cell activation through regulation of CD45 protein tyrosine phosphatase activity.[3]
Astragaloside II in conjunction with cisplatin can significant reduce cell viability, and arrest in S phase and increased apoptosis, suggests that astragaloside II can be served as autophagy inhibitor which restores chemosensitivity of anticancer agent cisplatin and enhances tumor cell death.[4]
