Sulongga-4 is a traditional Mongolian medicine prescription used for the treatment of gastroduodenal ulcer. However, molecular mechanism underlying the therapeutic effect of Sulongga-4 on gastroduodenal ulcer in Proteome has not been clarified. objective: Explore the molecular mechanism behind the therapeutic efficacy of traditional Mongolian medicine Sulongga-4 on the pyloric ligation-induced gastroduodenal ulcer in rats method: Gastroduodenal was induced by pyloric ligation in rats. The pathological changes of gastric and duodenal tissues were observed first, and then the serum levels of AST and ALT were measured. The significantly different proteins were verified by western blot and qRT-PCR. result: The proteomics results showed that the Mongolian medicine Sulongga-4 might act on pyloric ligation-induced gastroduodenal ulcer through differentially expressing several proteins including RPL35, RPL37 and LOC102548628 in gastric tissue, as well as Serpin b1a, Serpin b6a and Vtn in duodenal tissue via regulating ribosome, alcoholism and amoebiasis, complement and coagulation cascades pathways. In addition, the changes of serum AST and ALT levels in rats showed that gastroduodenal ulcer was associated with liver injury. conclusion: Sulongga-4 shows robust therapeutic effect against gastric duodenal ulcer. And this therapeutic effect is mainly associated with pathways of Ribosome, Alcoholism in gastric tissue, and Amoebiasis, Complement and coagulation cascades in duodenal tissue.","PeriodicalId":56153,"journal":{"name":"Natural Products Journal","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-09-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135863062","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Objective: This study evaluated the antioxidant, antibacterial, antifungal, anti-inflammatory, and antidiabetic potential of fractional extracts from P. pellucida plant derived from Can Tho City, Vietnam. Methods: Four fractional extracts were prepared using different polarity solvents (hexane, dichloromethane, ethyl acetate) and used to determine the best extract for each biological property. The fractions’ total alkaloid, phenolic, and flavonoid content were observed. The four extracts were evaluated for their potential bioactivities: antioxidant, antibacterial, antifungal, anti-inflammatory, and antidiabetic. Results: Correspond with the hexane, dichloromethane, ethyl acetate, and aqueous fractions, the total content of alkaloids was determined to be 255 ± 23.8; 157 ± 14.0; 219 ± 6.55; 221 ± 6.23 (mg AE/g extract), the total phenolic content was 112 ± 3.34; 141 ± 1.77; 234 ± 29.5; 123 ± 5.04 (mg GAE/g extract), whereas the total content of flavonoids was 423 ± 22.6; 169 ± 6.30; 1839 ± 18.8; 173 ± 22.6 (mg QE/g extract), respectively. The ethyl acetate fraction gave the best efficiency in DPPH, ABTS, iron reduction, and TAC methods (IC50 = 334 ± 2.10 µg/mL; 51.4 ± 0.41 µg/mL; 79.1 ± 0.40 µg/mL; and 83.0 ± 0.17 µg/mL, respectively). Antibacterial activity was investigated on 5 strains of Bacillus cereus, Escherichia coli, Staphylococcus aureus, Salmonella typhimunum, Pseudomonas aeruginosa; the results showed that the extracts were resistant to 5 strains of bacteria, especially best resistant in 2 fractions of ethyl acetate and aqueous. The minimum inhibitory concentration (MIC) value ranged from 0.5 to 32 mg/mL, while the minimum bactericidal concentration (MBC) value ranged from 16 to 64 mg/mL. The best anti-inflammatory activity was ethyl acetate with an IC50 value of 216.7 ± 7.2 µg/mL, close to that of Diclofenac at 205.4 ± 0.5. The antidiabetic activity was investigated based on the ability to inhibit α-amylase and α-glucosidase enzymes. The results showed that the best α-amylase inhibitors were hexane and dichloromethane (IC50 = 208.83 ± 2.41 and 191.60 ± 1.27 µg/mL, respectively), roughly equal to the acarbose (155.68 ± 2.59 µg/mL). The best α-glucosidase inhibitory fraction was ethyl acetate (IC50 of 157.04 ± 0.23 µg/mL), close to that of acarbose (116.45 ± 0.21 µg/mL).

Objective: Trianthema portulacastrum L., a plant commonly growing in India, is rich in antioxidant phytochemicals. This is responsible for scavenging free radicals and may provide radioprotective and anti-inflammatory effects in response to ionizing radiation. Methods: The effect of T. portulacastrum extracts was studied in hepatic cells, which are susceptible to radiation-induced damage and in macrophages, which are the primary inflammatory cells of the body. Results: T. portulacastrum stem extracts showed efficient free radical scavenging activity in hepatocytes and decreased radiation-induced lipid peroxidation in cell and mitochondrial membranes. Treatment of irradiated cells with T. portulacastrum stem extracts enhanced cell viability at lower concentration and reduced cell viability at higher concentration. Treatment with low concentration of T. portulacastrum stem extract also reduced cellular ROS generation and increased the concentration of cellular anti-oxidant, glutathione. T. portulacastrum extracts also showed remarkable anti-inflammatory properties in macrophages activated by the inflammatory agonist bacterial lipopolysaccharide (LPS). The extract reduced nitric oxide (NO) production and suppressed the expression of inflammatory genes. Conclusion: Together, these observations demonstrated a potential radioprotective role of T. portulacastrum extract mediated by both its antioxidant activity on hepatic epithelial cells and its anti-inflammatory activity on immune cells.","PeriodicalId":56153,"journal":{"name":"Natural Products Journal","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134951521","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
