Biological Activity: Notoginsenoside R2 (20(S)-Notoginsenoside R2; Ginsenoside Ng-R2) is an orally active notoginsenoside. Notoginsenoside R2 activates P90RSK and Nrf2 via the MEK1/2-ERK1/2 pathway to inhibit 6-OHDA-induced apoptotic damage in nerve cells. Notoginsenoside R2 upregulates SOX8/β-catenin by reducing miR-27a, thereby suppressing Aβ25-35-induced neuronal apoptosis and inflammatory responses. Notoginsenoside R2 alleviates lipid accumulation and mitochondrial dysfunction in diabetic nephropathy by inhibiting c-Src. Notoginsenoside R2 alleviates hepatic fibrosis by inducing hepatic stellate cell senescence and inhibiting the inflammatory microenvironment via JAK/STAT3 suppression. Notoginsenoside R2 can be used in research related to Parkinson's disease, Alzheimer's disease, diabetic nephropathy and hepatic fibrosis[1][2][3][4][5].
