説明Schisantherin B (STB) is a lignan originally isolated from S. sphenanthera fruit. It inhibits formation of advanced glycation end products (AGEs) in vitro. STB (0.1 mg/kg) decreases escape latency in the Morris water maze and increases spontaneous alternation in the Y-maze in a mouse model of Alzheimer''s disease induced by amyloid-β (1-42) . It increases glial expression of glutamate transporter 1 (GLP-1) and decreases immobility time in the forced swim test (FST) in mice, indicating antidepressant-like activity. STB also increases spontaneous alternation in the Y-maze in a mouse model of stress-induced short-term learning impairment induced by the FST.

使用Schisantherin B is a bioactive of lignans isolated from Schisandra chinesis which protect against cognitive deficits and neurodegeneration induced by Aβ1-42 in mice.
