6、Ginsenoside Rb1是中藥 Panax ginseng 的成分。Ginsenoside 抑制 Na+, K+-ATPase 活性，IC50 為 6.31.0 M。 Ginsenoside Rb1 也抑制 IRAK-1 激活及 NF-B p65 的磷酸化。IC & Target IRAK-1 p65 Na+, K+-ATPase Autophagy6.3 M (IC50)Mitophagy體外研究 Rat brain microsomal Na+, K+-ATPase activity is inhibited significantly and rapidly by Ginsenos

7、ide Rb1. The IC50 ofGinsenoside Rb1 for Na+,K+-ATPase is 6.31.0 M. The inhibition is enhanced with increasing the concentration ofGinsenoside Rb1 or decreasing that of Na+ and K+. Kinetic analysis reveals that Ginsenoside is an uncompetitiveinhibitor with respect to ATP1.Ginsenoside Rb1 significantl

8、y inhibits the activation of interleukin-1 receptor-associated kinase-1 (IRAK-1), IKK-, NF-B, and MAP kinases (ERK, JNK, and p-38); however, interaction between LPSand Toll-like receptor-4, IRAK-4 activation and IRAK-2 activation are unaffected2. Ginsenoside Rb1 is an ingredient ofa Chinese medicine

9、 Panax ginseng. Ginsenoside Rb1 is a major bioactive compound in the regulating pregnane Xreceptor (PXR)/NF-B signaling. Ginsenoside Rb1 is the compound with potent anti-inflammatory activity in ginsengsaponin extract (GSE). The concentration for Ginsenoside Rb1 (10 M) is optimized from a preliminar

10、y study to ensuresufficient anti-inflammatory activity and without apparent cytotoxicity. Ginsenoside Rb1 significantly reduces TNF-induced upregulation of IL-1 and iNOS mRNA levels, and restores the mRNA levels of PXR and CYP3A4 in LS174Tcells. TNF- causes a significant reduction in PXR protein lev

After overnight incubation, cells are treated with GSE (100 g/mL),Ginsenoside Rb1 (10 M), or CK (10 M) for 3 hours, followed by an additional incubation with or without TNF- (20ng/ml) for 6 hours. At the end of the incubation, cells are harvested and fixed with 4% paraformaldehyde solution at20C for 20 minutes. Af
