Saponins associated with Panax notoginseng (P. notoginseng) demonstrate significant therapeutic efficacy across multiple diseases. However, certain high-yield saponins face limited clinical applications due to their reduced pharmacological efficacy. This study synthesized and evaluated 36 saponin-1,2,3-triazole derivatives of ginsenosides Rg1/Rb1 and notoginsenoside R1 for anti-adipogenesis activity in vitro. The research revealed that the ginsenosides Rg1-1,2,3-triazole derivative a17 demonstrates superior adipogenesis inhibitory effects. Structure-activity relationships (SARs) analysis indicates that incorporating an amidyl-substituted 1,2,3-triazole into the saponin side chain via Click reaction enhances anti-adipogenesis activity. Additionally, several other derivatives exhibit general adipogenesis inhibition. Compound a17 demonstrated enhanced potency compared to the parent ginsenoside Rg1. Mechanistic investigations revealed that a17 exhibits dose-dependent inhibition of adipogenesis in vitro, accompanied by decreased expression of preadipocytes. Peroxisome proliferator-activated receptor γ (PPARγ), fatty acid synthase (FAS), and fatty acid binding protein 4 (FABP4) adipogenesis regulators. These findings establish the ginsenoside Rg1-1,2,3-triazole derivative a17 as a promising adipocyte differentiation inhibitor and potential therapeutic agent for obesity and associated metabolic disorders. This research provides a foundation for developing effective therapeutic approaches for various metabolic syndromes.

Objective:To evaluate the role of p38 mitogen-activated protein kinase (MAPK)/cyclic adenosine monophosphate response element-binding protein (CREB) signaling pathway in tetramethylpyrazine-induced reduction of hippocampal inflammatory responses in mice with sepsis-associated encephalopathy (SAE).Methods:Sixty healthy male C57BL6 mice, weighing 24-27 g, were divided into 4 groups ( n=15 each) using a random number table method: sham operation group (group Sham), sepsis group (group Sep), tetramethylpyrazine group (group TMP) and p38 MAPK inhibitor SB203580 group (group SB). The model of SAE was established by cecal ligation and puncture in anesthetized mice.Tetramethylpyrazine 10 mg/kg was injected intraperitoneally once a day at 3 days before the establishment of the model in TMP group, and SB203580 2.0 mg/kg was intraperitoneally injected at 30 min after the establishment of the model in SB group.The equal volume of normal saline was given intraperitoneally in Sham and Sep groups.At 1 day after operation, cognitive function was assessed by Morris water maze, and the escape latency and ratio of time spent in the target quadrant were recorded.The animals were sacrificed after the test, and hippocampal tissues were taken for determination of the contents of interleukin-1beta (IL-1β), tumor necrosis factor-alpha (TNF-α) and IL-6 (by enzyme-linked immunosorbent assay) and for detection of the expression of phosphorylation of p38 MAPK, GSK3 and CREB and expression of brain-derived neurotrophic factor (BDNF) (by Western blot). Results:Compared with group Sham, the escape latency was significantly prolonged, the ratios of time spent in the target quadrant were decreased, the contents of IL-1β, TNF-α and IL-6 were increased, the phosphorylation of hippocampus p38 MAPK was increased, the phosphorylation of GSK3 and CREB were decreased, and the expression of BDNF was down-regulated in Sep, TMP and SB groups ( P<0.05). Compared with group Sep, the escape latency was significantly shortened, the ratios of time spent in the target quadrant were increased, the contents of IL-1β, TNF-α and IL-6 were decreased, the phosphorylation of hippocampus p38 MAPK was decreased, the phosphorylation of GSK3 and CREB were increased, and the expression of BDNF was up-regulated in TMP and SB groups ( P<0.05). Compared with group TMP, no significant change was found in the parameters mentioned above in group SB ( P>0.05). Conclusion:p38 MAPK/CREB signaling pathway is involved in the process of tetramethylpyrazine-induced reduction of hippocampal inflammatory responses in mice with SAE.

Objective:To observe the characteristics of the phagocytosis and bactericidal function of multidrug-resistant Mycobacterium tuberculosis(MDR- Mtb)-infected macrophage model, and the changes of the immune response and metabolic function in the process of phagocytosis and bactericidal function, aiming to provide reference for studying the role and mechanism of macrophages in the occurrence and development of multidrug-resistant tuberculosis(MDR-TB). Methods:We established MDR- Mtb and H37Rv-infected macrophage models, and used the colony-forming unit (CFU), Magnetic Luminex ? Assay and Cholesterol Assay kit to observe the effects on phagocytosis and bactericidal function, the secretion of Th1(IL-12/23 p40, IL-27 and TNF-α) and Th2 cytokines (IL-6 and IL-10) and cholesterol metabolism. The data were analyzed by SPSS25.0 software. The data were expressed as Mean± SD and analyzed by t test or F test. P<0.05 was considered statistically significant. Results:(1) After MDR- Mtb-infected macrophages, the intracellular CFU gradually increased and reached the highest at 24 h, while the extracellular CFU gradually decreased and reached the lowest at 24 h. The intracellular CFU at 48 h was lower than that at 24 h, while the extracellular CFU was higher than that at 24 h ( P<0.05). Both intracellular and extracellular CFU at 48 h were close to those at 4 h ( P>0.05). The intracellular CFU was lower than the H37Rv group at 8-48 h, while the extracellular CFU was higher than the H37Rv group ( P<0.05). (2) The level of IL-12/23 p40, IL-27, TNF-α, IL-6 and IL-10 of MDR-TB group were higher than those of blank group ( P<0.05), but the level of TNF-α and IL-6 at 24 h and 48 h were higher than that at 4 h ( P<0.05). IL-12/23 p40 and TNF-α at 48 h and IL-6 at 24 h were lower than those of the H37Rv group, while IL-27 at 48 h was higher than that of the H37Rv group ( P<0.05). (3) The levels of cholesterol of MDR-TB group at 24 h and 48 h were lower than those of 4 h and blank group ( P<0.05), but the level of cholesterol was similar to the H37Rv group at any time ( P>0.05). (4) TNF-α reached the highest when the intracellular CFU reached the highest at 24 h, and IL-6 reached the highest when the intracellular CFU decreased at 48 h. With the decreasing of cholesterol expression, the intracellular CFU increased and then decreased. Conclusions:MDR- Mtb could induce the phagocytosis and bactericidal function of macrophages, increase the expression of Th1 and Th2 cytokines and promote the utilization and consumption of cholesterol, but this function was weaker than that of H37Rv strain.
