Biological Activity
Description: Ginsenoside Rk1 has anti-tumor, and anti-platelet aggregation activities. Ginsenoside Rk1 can strongly inhibit permeability induced by VEGF, advance glycation end-product, thrombin, or histamine in human retinal endothelial cells, it reduces the vessel leakiness of retina in a diabetic mouse model; this anti-permeability activity of Rk1 is correlated with enhanced stability and positioning of tight junction proteins at the boundary between cells; Rk1 induces phosphorylation of myosin light chain and cortactin, which are critical regulators for the formation of the cortical actin ring structure and endothelial barrier.
Targets: VEGFR
In vitro:

Three new dammarane glycosides from heat processed ginseng.[Pubmed: 12214849]
Three new dammarane glycosides were isolated from the processed ginseng (SG; Sun Ginseng).
METHODS AND RESULTS:
Their structure were determined to be 3beta,12beta-dihydroxydammar-20(21),24-diene-3-O-beta-D-glucopyranosyl(1 --> 2)-beta-D-glucopyranoside; 3beta,12beta-dihydroxydammar-20(21),24-diene-3-O-beta-D- glucopyranoside and 3beta,6alpha,12beta-trihydroxydammar-20(21),24-diene-6-O-beta-D-glucopyranoside based on spectroscopic evidences.
CONCLUSIONS:
The compounds were named as Ginsenoside Rk1, Ginsenoside Rk2, and ginsenoside Rk3 respectively.
