Through the combination of various chromatographies, 11 new 20(S)-protopanaxadiol (PPD) type saponins, named as notoginsenosides NL-E1 - NL-E4 (1-4), NL-F1 (5), NL-F2 (6), NL-G1 (7), NL-G2 (8), NL-H1 - NL-H3
Osteolysis is a principal reason for arthroplasty failure like aseptic loosening induced by Titanium (Ti) particle. It is a challenge for orthopedic surgeons. Recent researches show that 20(S)-protopanaxadiol can inhibit inflammatory cytokine release in vitro. This study aims to assess the
Ginsenosides, bioactive compounds of Panax Ginseng C.A. Meyer, are divided into protopanaxadiol (PD) and protopanaxtriol (PT). The aim of this study was to evaluate the protective effects of different PD and PT combination ratios on liver inflammation and apoptosis in hyperlipidemic apo E KO mice.
Ginseng is a perennial herb that contains various medicinal substances. The major active constituents of ginseng are ginsenosides, which have multifarious biological activities. Some pharmacological activities are closely dependent on the stereoisomers derived from the configuration at C20. In this
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
20( S)-Protopanaxadiol (PPD) is one of the metabolites of ginsenosides from Panax ginseng. In this study, we demonstrate that PPD inhibits the increase in lipopolysaccharide (LPS)-induced inducible nitric oxide synthase (iNOS) expression through inactivation of nuclear factor-kappaB by preventing
Inefficient diabetic ulcer healing and scar formation remain a challenge worldwide, owing to a series of disordered and dynamic biological events that occur during the process of healing. A functional wound dressing that is capable of promoting ordered diabetic wound recovery is eagerly anticipated.
Pyxinol, the main metabolite of 20S-protopanaxadiol in human liver, was chosen as a novel skeleton for the development of anti-inflammatory agents. Pyxinol derivatives modified at C-3, C-12, or C-25 and selected stereoisomers were designed, prepared, and investigated for in vitro
Glucocorticoids are steroid hormones that regulate inflammation, growth, metabolism, and apoptosis via their cognate receptor, the glucocorticoid receptor (GR). GR, acting mainly as a transcription factor, activates or represses the expression of a large number of target genes, among them, many
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
20(S)-protopanaxadiol (PPD) possesses various biological properties, including anti-inflammatory, antitumor and anti-fatigue properties. Recent studies found that PPD functioned as a neurotrophic agent to ameliorate the sensory deficit caused by glutamate-induced excitotoxicity through its
Atherosclerosis mainly contributes to cardiovascular disease, a leading cause of global morbidity and mortality. Panax notoginseng saponins (PNS) are proved to therapeutically attenuate the formation of atherosclerotic lesions. According to different sapogenin, PNS are generally classified
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
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
Ginseng (Panax ginseng C.A. Mey.) is commonly used in traditional oriental medicine for its wide spectrum of medicinal properties, including anti-inflammatory, antitumorigenic, adaptogenic and anti-aging properties. 20(S)-Protopanaxadiol (PPD), the main intestinal metabolite of ginsenosides, is one
