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.

    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.
