Properties
Ginsenoside CK is a white crystalline powder, soluble in methanol, ethanol, DMSO and other organic solvents, derived from ginseng rhizome, Gynostemma pentaphyllum.
Pharmacological action
Ginsenoside CK is the main metabolite of protopanaxadiol saponins in human intestinal tract. Studies have shown that the pharmacological activities of ginsenosides are mainly mediated through its metabolic component CK, and CK has a variety of pharmacological activities, such as anti-inflammatory, anti-tumor, anti-allergic, anti-diabetic, hepatoprotective, neuroprotective, and cardiovascular protection.
Description
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.
Uses
Ginsenoside C-K is reported to exhibit anti-wrinkle effects. Also, it potentiates tumor necrosis factor (TNF)-related apotosis-inducing ligand (TRAIL)-induced apotosis in HCT116 colon cancer.
General Description
This substance is a primary reference substance with assigned absolute purity (considering chromatographic purity, water, residual solvents, inorganic impurities). The exact value can be found on the certificate.
Check Digit Verification of cas no
The CAS Registry Mumber 39262-14-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,9,2,6 and 2 respectively; the second part has 2 digits, 1 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 39262-14:
(7*3)+(6*9)+(5*2)+(4*6)+(3*2)+(2*1)+(1*4)=121
121 % 10 = 1
So 39262-14-1 is a valid CAS Registry Number.

Rational design of a β-glycosidase with high regiospecificity for triterpenoid tailoring

Triterpenoids with desired glycosylation patterns have attracted considerable attention as potential therapeutics for inflammatory diseases and various types of cancer. Sugar-hydrolyzing enzymes with high substrate specificity would be far more efficient than other methods for the synthesis of such specialty triterpenoids, but they are yet to be developed. Here we present a strategy to rationally design a β-glycosidase with high regiospecificity for triterpenoids. A β-glycosidase with broad substrate specificity was isolated, and its crystal structure was determined at 2.0 ? resolution. Based on the product profiles and substrate docking simulations, we modeled the substrate binding modes of the enzyme. From the model, the substrate binding cleft of the enzyme was redesigned in a manner that preferentially hydrolyzes glycans at specific glycosylation sites of triterpenoids. The designed mutants were shown to produce a variety of specialty triterpenoids with high purity.
