Anaphylactic Rare Saponins Separated from Panax notoginseng Saponin and a Proteomic Approach to Their Anaphylactic Mechanism.

ABSTRACT: In recent years, many traditional Chinese medicine injections based on Panax notoginseng saponin (PNS) have been reported to cause anaphylaxis. Previous studies on the anaphylactic saponins of PNS and their mechanism are inadequate. In this study, potential anaphylactic saponins were obtained by the separation of PNS and preparation of each individual component through comprehensive techniques, such as liquid chromatography, preparative chromatography, HPLC, NMR, and MS. The anaphylactic abilities of these saponins were tested using RBL-2H3 cells via a β-hexosaminidase release rate test. The results for the mechanism of anaphylaxis were obtained by a proteomic analysis using RBL-2H3 cells. The results indicate that, among all the saponins prepared, gypenoside LXXV and notoginsenoside T5 showed strong anaphylactic abilities and notoginsenoside ST-4 and ginsenoside Rk3 showed weak anaphylactic abilities. These 4 saponins can induce anaphylaxis via direct stimulation of effector cells. The gene oncology enrichment analysis results showed that, among these saponins, only gypenoside LXXV was related to organelles of the endoplasmic reticulum and Golgi apparatus and biological processes in response to organic cyclic compounds. Four proteins in RBL-2H3 cells with the accession numbers A0A0G2JWQ0, D3ZL85, D4A5G8, and Q8K3F0 were identified as crucial proteins in the anaphylactic process. This research will help traditional Chinese medicine injection manufacturers strengthen their quality control and ensure the safety of anaphylactic saponins.

Project description:BackgroundPanax notoginseng saponins (PNS) have been deemed effective herb compounds for treating ischaemic stroke (IS) and improving the quality of life of IS patients. This study aimed to investigate the underlying mechanisms of PNS in the treatment of IS based on network pharmacology.MethodsPNS were identified from the Traditional Chinese Medicine System Pharmacology (TCMSP) database, and their possible targets were predicted using the PharmMapper database. IS-related targets were identified from the GeneCards database, OMIM database, and DisGeNET database. A herb-compound-target-disease network was constructed using Cytoscape, and protein-protein interaction (PPI) networks were established with STRING. GO enrichment and KEGG pathway analysis were performed using DAVID. The binding of the compounds and key targets was validated by molecular docking studies using AutoDock Vina. The neuroprotective effect of TFCJ was substantiated in terms of oxidative stress (superoxide dismutase, glutathione peroxidase, catalase, and malondialdehyde) and the levels of IGF1/PI3K/Akt pathway proteins.ResultsA total of 375 PNS targets and 5111 IS-related targets were identified. Among these targets, 241 were common to PNS, and IS network analysis showed that MAPK1, AKT1, PIK3R1, SRC, MAPK8, EGFR, IGF1, HRAS, RHOA, and HSP90AA1 are key targets of PNS against IS. Furthermore, GO and KEGG enrichment analysis indicated that PNS probably exert therapeutic effects against IS by regulating many pathways, such as the Ras, oestrogen, FoxO, prolactin, Rap1, PI3K-Akt, insulin, PPAR, and thyroid hormone signalling pathways. Molecular docking studies further corroborated the experimental results.The network pharmacology results were further verified by molecular docking and in vivo experiments.ConclusionsThe ameliorative effects of PNS against IS were predicted to be associated with the regulation of the IGF1-PI3K-Akt signalling pathway. Ginsenoside Re and ginsenoside Rb1 may play an important role in the treatment of IS.

Project description:Statins cannot be used for some active liver diseases, which limits its application to some extent. The combined use of statins with other drugs may be one of the ways to solve this dilemma.This research aims to evaluate the effects of atorvastatin combined with Panax notoginseng saponins (PNS) on rats with atherosclerosis (AS) complicated with hepatic injury.Seventy-two male Wistar rats were randomly categorized into control group (without any intervention, Group A) and AS model groups, which were divided into hepatic injury (Groups B-E) and nonhepatic injury (Groups F-I) groups. Hepatic and nonhepatic injury groups were intragastrically treated with 5.5 mg/kg·d atorvastatin (Group B, F), 200 mg/kg·d PNS (Group C, G), 5.5 mg/kg·d atorvastatin + 200 mg/kg·d PNS (Group D, H), and normal saline (Group E, I). After 8 weeks, total cholesterol (TC), triglyceride (TG), high density lipoprotein-cholesterol, low density lipoprotein-cholesterol (LDL-C), and serum calcium were analyzed to evaluate the hypolipidemic effect. Serum alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase, total bilirubin, and r-glutamyltransferase levels were measured to assess liver function. The thoracic aortas were used for hematoxylin-eosin staining.In both hepatic injury and nonhepatic injury groups, TC, TG and LDL-C levels significantly decreased in Groups B, D, F, and H. ALT and AST levels significantly increased in Group B, but significantly decreased in Groups C and D. The aortic intima thickness was significantly lower in Groups B, D, F, and H than that in the normal saline group.The combination of atorvastatin and PNS treatment showed a significant hypolipidemic effect and hepatic enzyme stability function.The single use of Panax notoginseng saponins (PNS) in the rat model for atherosclerosis significantly reduced Ca2+ content in serum, whereas the effect of lowing total cholesterol (TC), triglyceride (TG), and low density lipoprotein-cholesterol (LDL-C) is not apparent, especially as compared with atorvastatin treatmentPNS combined with atorvastatin treatment of the rat model for atherosclerosis displayed a noticeable, synergistic effect that allowed for better reduction of TC, TG, LDL-C and Ca2+ in the serum than that with the single use of PNS or atorvastatinIn the rat liver injury combined with atherosclerosis model, the single use of PNS significantly improved liver function, whereas atorvastatin alone only aggravated liver injury in the rat model. The effect of PNS combined with atorvastatin on liver function was significantly better than that of atorvastatin aloneThe combined use of PNS and atorvastatin showed good stability of liver function on the liver injury combined with atherosclerosis model.
