Ginsenoside compound K (C-K) is a metabolite of the protopanaxadiol-type saponins of Panax ginseng C.A. Meyer, has long been used to treat against the development of cancer, inflammation, allergies, and diabetes; C-K acts as a unique HUVEC migration inhibitor by regulating MMP expression, as well as the activity of SPHK1 and its related sphingolipid metabolites. C-K exhibits anti-inflammatory effects by reducing iNOS and COX-2, C-K exhibits an inhibition against the activity of CYP2C9 and CYP2A6 in human liver microsomes with IC50s of 32.0±3.6 μM and 63.6±4.2 μM, respectively. C-K promotes Aβ clearance by enhancing autophagy via the mTOR signaling pathway in primary astrocytes.
