Descriptions:
Hyperoside, a flavonoid glycoside isolated from Artemisia capillaris, has protective effects against CCl4-induced acute liver injury, and this protection is likely due to enhancement of the antioxidative defense system and suppression of the inflammatory response.[1]
Hyperoside can protect Aβ-induced primary cultured cortical neurons via PI3K/Akt/Bad/Bcl XL -regulated mitochondrial apoptotic pathway, and they raise the possibility that hyperoside could be developed into a clinically valuable treatment for Alzheimer's disease and other neuronal degenerative diseases associated with mitochondrial dysfunction.[2]
Hyperoside is a strong inhibitor of HBsAg and HBeAgsecretion in 2.2.15 cells and DHBV-DNA levels in the HBV-infected duck model.[3]
Hyperoside isolated from Camptotheca acuminata, has antifungal activity, may serve as leads for the development of fungicides.[4]
Hyperoside has cytoprotective effects against hydrogen peroxide (H2O2)-induced cell damage by scavenging intracellular ROS and enhancing antioxidant enzyme activity, and protects HUVECs against H(2)O(2) damage, at least partially, by activating the ERK signaling pathway. [5,6]
Hyperoside has a variety of pharmacological effects including anti-viral, anti-oxidative, and anti-apoptotic activities and it has anti-Inflammatory activity through the suppression of nuclear factor-κB activation in mouse peritoneal macrophages.[7]
