Neuroprotective and Cognition-Enhancing Effects of Compound K Isolated from Red Ginseng

The present study was aimed at elucidating the effect of compound K derived from red ginseng on memory function in mouse model and glutamate-induced cytotoxicity in mouse hippocampal HT22 cells. Compound K induced antioxidant enzymes in nuclear factor (erythroid-derived 2)-like 2 (Nrf2)-mediated manner, and effectively attenuated cytotoxicity and mitochondrial damage induced by glutamate in HT22 cells. However, the cytoprotective effect by...
