Ginsenosides are the major principles of Panax ginseng C. A. Meyer (Araliaceae) used as a mild oriental folk medicine. In this report, we have examined the inhibitory potency of protopanaxadiol ginsenosides (PPDGs) such as Rb1, Rb2 and Rc, and their co-treatment effect with known tumor necrosis
To investigate the protective effects of protopanaxadiol-type ginsenoside (PDG) and its metabolite ginsenoside M1 (G-M1) on carbon tetrachloride (CCl(4))-induced chronic liver injury in ICR mice, we carried out conversion of protopanaxadiol-type ginsenosides to ginsenoside M1 using snailase. The
Ginsenoside is a major active component of ginseng, which exhibits various pharmacological properties such as hepatoprotection, tumor suppression and diabetes resistance. In this study, the anti-diabetic effects of protopanaxadiol (PPD) and protopanaxatriol (PPT)-type saponins were explored and
BACKGROUND
Korean Red Ginseng (KRG) is a representative traditional herbal medicine with many different pharmacological properties including anticancer, anti-atherosclerosis, anti-diabetes, and anti-inflammatory activities. Only a few studies have explored the molecular mechanism of KRG-mediated
Among important components of American ginseng, protopanaxadiol (PPD) showed more active anticancer potential than other triterpenoid saponins. In this study, we determined the in vivo effects of PPD in a mouse cancer model first. Then, using human colorectal cancer cell lines, we observed
SC-514, an inhibitor of IkappaB kinase beta (IKKbeta), blocked the TNF-alpha-induced activation of nuclear factor-kappaB (NF-kappaB) as well as the TNF-alpha-promoted metastasis of murine colon adenocarcinoma cells. We investigated the effect of 20-O-beta-D-glucopyranosyl-20(S)-protopanaxadiol (M1),
BACKGROUND
Inappropriate use of acetaminophen (APAP) can lead to morbidity and mortality secondary to hepatic necrosis.
OBJECTIVE
We evaluated the beneficial effect and molecular mechanism of Korean red ginseng (KRG) on the APAP-mediated hepatotoxicity and identified a major component of KRG for
OBJECTIVE
Compound K (C-K; 20-O-D-glucopyranosyl-20(S)-protopanaxadiol) is a functional ligand of the glucocorticoid receptor (GR) and regulates toll-like receptor-4-dependent inflammation. Here, the role of C-K in the regulation of zymosan-mediated inflammation was investigated in murine bone
Spinal cord injury (SCI) is one of the most devastating medical conditions; however, currently, there are no effective pharmacological interventions for SCI. Ginsenoside Rg3 (GRg3) is one of the protopanaxadiols that show anti-inflammatory, anti-oxidant, and neuroprotective effects. The present
Ginsenoside Rg1 (Rg1), a protopanaxadiol saponin extracted from Chinese medicine Panax ginseng C.A. Meyer, has been demonstrated to inhibit the cardiac hypertrophy. However, the molecular mechanisms underlying the inhibition remain poorly understood. Activation of nuclear factor-kappa B (NF-κB)
BACKGROUND
Panax notoginseng is commonly used for the treatment of cardiovascular diseases in China. The present study investigates the effects of three different saponin fractions (ie total saponins, PNS; protopanaxadiol-type saponin, PDS; and protopanaxatriol-type saponin, PTS) and two major
Ginseng (the root of Panax ginseng C.A. Meyer, family Araliaceae), which contains protopanaxadiol ginsenoside Rb1 and protopanaxatriol ginsenoside Re as main constituents, is frequently used to treat cancer, inflammation, and stress. In the preliminary study, protopanaxatriol ginsenoside Re
Ginseng (the root of Panax ginseng C. A. MEYER), which contains protopanaxadiols and protopanaxatriols as its main constituents, has been used for many disorders, such as cancer, diabetes, inflammation, and hyperlipidemia. Of these ginsenosides, protopanaxadiol ginsenoside Rh2 alone is reported to
BACKGROUND
Ginsenoside Rc (G-Rc) is one of the major protopanaxadiol-type saponins isolated from Panax ginseng, a well-known medicinal herb with many beneficial properties including anticancer, anti-inflammatory, antiobesity, and antidiabetic effects. In this study, we investigated the effects of
Microglial activation plays a pivotal role in the pathogenesis of various neurologic disorders, such as cerebral ischemia, Alzheimer's disease, and Parkinson's disease. Thus, controlling microglial activation is a promising therapeutic strategy for such brain diseases. In the present study, we found
