진세노사이드-Rb1

개요Ginsenoside Rb1, a glycosylated PPD type ginsenoside with two sugars linked to C-3 and two sugars linked to C-20, is the major active constituent of American ginseng. Studies have demonstrated the anti-aging effects of ginsenoside Rb1 at both animal and cell levels. 20-O-β-D-glucopyranosyl-20(S)-protopanaxadiol (20GPPD) is the major ingredient of ginsenoside Rb1, which has been shown to increase HAS2 expression by phosphorylating ERK and AKT signaling in human keratinocytes in a dose-dependent manner in vitro.

용도A major bioactive component of panax ginseng that promotes neurotransmitter release by modulating phosphorylation of synapsins through a cAMP-dependent protein kinase pathway. It has been reported to display immunostimulatory and anticancer effects.

일반 설명Ginsenoside Rb1 (Gypenoside Ⅲ) is a protopanaxadiol that has diverse in vitro and in vivo effects, including neuroprotective, anti-inflammatory, and anti-obesity actions. Ginsenoside Rb1, a main constituent of the root of Panax ginseng, inhibits Na+, K+-ATPase activity with IC50 of 6.3±1.0 μM. Ginsenoside also inhibits IRAK-1 activation and phosphorylation of NF-κB p65. Ginsenoside Rb1 reduces the expressions of TLR3, TLR4 and TRAF-6, and down-regulates the levels of TNF-α, IFN-β and iNOS.

정의ChEBI: Ginsenoside Rb1 is a ginsenoside found in Panax ginseng and Panax japonicus var. major that is ginsenoside Rd in which the beta-D-glucopyranoside group at position 20 is replaced by a beta-D-glucopyranosyl-beta-D-glucopyranoside group. It has a role as a neuroprotective agent, an anti-obesity agent, an anti-inflammatory drug, an apoptosis inhibitor, a radical scavenger and a plant metabolite. It is a ginsenoside, a glycoside and a tetracyclic triterpenoid. It is functionally related to a ginsenoside Rd.
