Ginsenoside Rb1's IC50 against Na+ and K+-ATPase is 6.3±1.0 μM. Simultaneously, ginsenoside is a non-competitive ATP coupling, as demonstrated by the kinetic analysis of the rise in ginsenoside Rb1 concentration or the increase in Na+ and K+ concentration [1]. The reduction of IKK-β and IRAK-1 receptor-associated pump 1 (IRAK-1) was significantly inhibited by ginsenoside Rb1, which also improved the inhibitory effect. MAP moieties (ERK, JNK, and p-38) and NF-κB activation; however, no connection has been found between LPS and Toll-like receptor 4 responses, IRAK-2 activation, or IRAK-4 activation [2]. Rb1 is a part of ginseng, a traditional Chinese medicine. The primary bioactive ingredient that controls pro-alkane X receptor (PXR)/NF-κB signaling is ginsenoside Rb1. Ginsenoside Rb1 in ginsenoside extract (GSE) exhibits strong anti-inflammatory properties. Based on preliminary studies, the concentration of ginsenoside Rb1 (10 μM) in cells was optimized to ensure adequate anti-inflammatory activity without evident toxicity. Ginsenoside Rb1 returned the mRNA levels of PXR and CYP3A4 to LS174T cells and significantly decreased the TNF-α-induced upregulation of IL-1β and iNOS. Ginsenoside Rb1 significantly eliminated both the significant increase in the ratio of phosphorylated to total NF-κB p65 and the significant decrease in PXR protein levels caused by TNF-α [3].

Ginsenoside Rb1, at doses of 30 mg/kg and 60 mg/kg, significantly reduced lung damage as shown by histology. In older adults, ginsenoside Rb1 at 30 mg/kg and 60 mg/kg significantly reduced histological lung damage [4]. Rb1) has a positive impact on the underlying mechanism of intestinal membrane microvascular wafer permeability generated by lipopolysaccharide (LPS) and is a constituent of the traditional Chinese medication ginseng. Thirty minutes after cosmetic LPS infusion, ginsenoside Rb1 (5 mg/kg) flowed via the left jugular system in certain stents. Within microvessels, ginsenoside Rb1 decreases the amount of caveolae in the cell skin. Due to its capacity to suppress NF-κB and Src activation, ginsenoside Rb1 improves microvascular hyperpermeability following endotoxin demand and eliminates intestinal edema by decreasing development of caveolae and connections [5].

| Additional Infomation |
Ginsenoside Rb1, found in ginseng (Panax ginseng) and Japanese ginseng (Panax japonicus var. major), is a derivative of ginsenoside Rd, in which the β-D-glucopyranoside group at position 20 is replaced by a β-D-glucopyranoside-β-D-glucopyranoside group. It possesses multiple functions, including neuroprotection, anti-obesity, anti-inflammation, inhibition of apoptosis, free radical scavenging, and as a plant metabolite. It is a ginsenoside, glycoside, and tetracyclic triterpenoid compound functionally related to ginsenoside Rd. Ginsenosides are a class of steroidal glycosides and triterpenoid saponins, found only in plants of the genus Panax. Ginsenosides have been a focus of research because they are considered the active ingredients behind ginseng's efficacy. Their effects are complex and difficult to isolate because ginsenosides appear to affect multiple pathways. Rb1 is most abundant in American ginseng (Panax quinquefolius). Rb1 appears to affect the reproductive system of the testes in animals. Recent studies have shown that Rb1 affects rat embryonic development and has teratogenic effects, leading to birth defects. Another study suggests that Rb1 may indirectly increase testosterone production in male rats by stimulating luteinizing hormone. Ginsenoside rb1 has been reported to be present in Japanese ginseng (Panax japonicus), licorice (Glycyrrhiza uralensis), and several other organisms with relevant data.
