Descriptions:
Anemoside B4(AB4) and tetrandrine(Tet) have some reversal effect on resistant to L-OHP in Lo Vo/L-OHP cells, the molecular mechanism of the resistance reverse effect was related to down-regulation of P-gp for AB4 and down-regulation of z DHHC9 for Tet.[1]
Anemoside B4, anemonin, berberine, jatrorrhizine, palmatine, aesculin, and esculetin are active ingredients of Pulsatillae Decoction , can inhibit the production of IL-6,secretion of IL-8, downregulate E-selectin expression, and decrease the content of TXB(2), they reduce inflammatory response, thus relieving intestinal dysfunction via multiple pathways.[2]
Anemoside B4 might potentially have a capacity to regulate immune responses in vivo via changes in production of these select cytokines by infected endothelial cells.[3]
