Descriptions:
Puerarin is the most abundant of flavonoid derivatives in the root of Pueraria lobata (Willd) Ohwi, has antioxidant activity and can impair CYP-catalysed drug metabolism.[1]
Puerarin can reduce the atherogenic properties of dietary cholesterol in rats, the hypocholesterolemic function may be due to the promotion of cholesterol and bile acids excretion in liver. [2]
Puerarin could inhibit oxidative stress through the activation of phosphatidylinositol 3-kinase (PI3K)-Akt pathway, could significantly reduce traumatic brain injury (TBI)-induced neuronal degeneration, accompanied by the partial restoration of the redox disturbance and enhanced expression of phospho-Akt in the pericontusional cortex after TBI.[3]
Puerarin may act as an intracellular ROS scavenger, and its antioxidant properties may protect against Abeta25-35-induced cell injury,and apoptosis and could also promote the survival of PC12 cells.[4]
Puerarin can ameliorate Aβ(1-42)-induced and reverse the increase of in the hippocampus, the attenuation is associated with the activation of and of Bad, suggests that puerarin may be an anti-candidate drug to suppress both -related neuronal cell and dysfunction of the system.[5]
