Dear visitor, this is a machine-translated article. It makes perfect sense in its original language (Czech), and is fully backed by independent scientific literature. The translation, though, is far from perfect and takes patience and imagination, if you decide to read it.

20-O-glucosyl-PPD (Compound K)

20-O-glucosyl-protopanaxadiol, compound K

It is the main product of bacterial hydrolysis of panaxosides that occurs in the intestine:


R1 = -H
R2 = -Glc

  • In stressed mice, cortisol is reduced in plasma. ( Kim2003iii )
  • It has all the panaxosides the strongest effect against the allergic reaction . In experimental skin anaphylaxis (PCA), 99% suppressed an allergic reaction at 25 mg / kg intraperitoneally and 98% suppressed orally. At 10 mg / kg, suppression of the allergic reaction was 44%. The strong anti-allergic effect of Compound K was demonstrated in other in vitro tests. It is not a histamine receptor antagonist. ( Choo2003aag )
  • Protected chondrocytes in rheumatoid arthritis models in vitro ( Choi2013jec ) and the rat model ( Chen2014gmc ).
  • It inhibited angiogenesis by regulating sphingosine kinase 1 found in an in vitro assay on human vascular endothelial cells. ( Shin2014gci )
  • It inhibited angiogenesis by inhibiting MAP kinase and protein kinase B (PKB). ( Jeong2010cib )
  • It has shown an anti-inflammatory effect in in vivo experimental inflammation in animals. ( Lee2005ape , Shin2005egr )
  • It has demonstrated an anti-inflammatory effect in vitro by reducing the production of NO and prostaglandin E2 in activated macrophages by inhibiting the transcription factor NF-κB. ( Park2005ieg )
  • It acts inhibitory on the neuronal form of nicotinic acetylcholine receptors (α3β4). ( Lee2003deb )
  • In addition to the above, antidiabetic, cytoprotective, neuroprotective and hepatoprotective effects were detected for K. ( Yang2015rbp )
