Antibacterial activity and mechanism of luteolin isolated from Lophatherum gracile Brongn. against multidrug-resistant Escherichia coli. Front Pharmacol 2024; 15:1430564. [PMID: 38983919 PMCID: PMC11232434 DOI: 10.3389/fphar.2024.1430564] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/10/2024] [Accepted: 06/05/2024] [Indexed: 07/11/2024] Open
Abstract
Infections caused by multidrug-resistant (MDR) bacteria have become a major challenge for global healthcare systems. The search for antibacterial compounds from plants has received increasing attention in the fight against MDR bacteria. As a medicinal and edible plant, Lophatherum gracile Brongn. (L. gracile) has favorable antibacterial effect. However, the main antibacterial active compound and its antimicrobial mechanism are not clear. Here, our study first identified the key active compound from L. gracile as luteolin. Meanwhile, the antibacterial effect of luteolin was detected by using the broth microdilution method and time-kill curve analysis. Luteolin can also cause morphological structure degeneration and content leakage, cell wall/membrane damage, ATP synthesis reduction, and downregulation of mRNA expression levels of sulfonamide and quinolones resistance genes in multidrug-resistant Escherichia coli (MDR E. coli). Furthermore, untargeted UPLC/Q-TOF-MS-based metabolomics analysis of the bacterial metabolites revealed that luteolin significantly changed riboflavin energy metabolism, bacterial chemotaxis cell process and glycerophospholipid metabolism of MDR E. coli. This study suggests that luteolin could be a potential new food additive or preservative for controlling MDR E. coli infection and spread.

Xu Q, Tian W, He S, Zhou M, Gao Y, Liu X, Sun C, Ding R, Wang G, Chen H. Apocarotenoids from Equisetum debile Roxb. ex Vaucher regulate the lipid metabolism via the activation of the AMPK/ACC/SREBP-1c signaling pathway. Bioorg Chem 2023; 138:106639. [PMID: 37276680 DOI: 10.1016/j.bioorg.2023.106639] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/03/2023] [Revised: 05/14/2023] [Accepted: 05/23/2023] [Indexed: 06/07/2023]
Abstract
Sixteen undescribed apocarotenoids (1-16), along with 22 known analogues, were isolated from the aerial parts of Equisetum debile. Their structures, including absolute configurations, were elucidated by NMR, HRESIMS, X-ray diffraction analysis, the modified Mosher's method and the quantum-chemical calculation of electronic circular dichroism (ECD) spectra. Compounds 1-9, 11-12 are the first example of C16-apocarotenoids appeared in nature. The plausible biosynthetic pathway of 1-16 was proposed. Moreover, the isolates were evaluated for their lipid-lowering activity, and the results showed that 13, 14, 15, 22, 31, 32 and 33 could remarkably decrease the levels of both TC and TG in FFA induced HepG2 cells at 20 μM. The oil red staining assay further demonstrated the lipid-lowering effects of 13, 14 and 15. The western blot results indicated that compounds 13, 14 and 15 could regulate the lipid metabolism via the activation of the AMPK/ACC/SREBP-1c signaling pathway. A preliminary structure-activity relationship (SAR) study of the isolates indicated that the apocarotenoids with 6/5 ring system displayed more potent lipid-lowering effects.

Cui X, Zhang B, Li Z, Li C, Li J. Zhuyeqing liquor promotes longevity through enhancing stress resistance via regulation of SKN-1 and HSF-1 transcription factors in Caenorhabditis elegans. Exp Gerontol 2023; 174:112131. [PMID: 36822487 DOI: 10.1016/j.exger.2023.112131] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/14/2022] [Revised: 02/03/2023] [Accepted: 02/20/2023] [Indexed: 02/25/2023]
Abstract
Zhuyeqing liquor (ZYQL) is well-known traditional functional liquor in China that contains twelve crude drugs. Studies have shown that ZYQL has many beneficial effects, but its anti-aging effect has not been reported. Here, we found that ZYQL had excellent antioxidant activity in vitro. In C. elegans, ZYQL could significantly extend the lifespan, and decreased aging related phenotype including accumulation of lipofuscin and the decrease of food intake and motility. Further, ZYQL significantly reduced ROS level and enhanced the antioxidant defense in C. elegans. ZYQL increased transcriptional activity of transcription factors HSF-1 and SKN-1, and ZYQL-mediated longevity was dependent on these factors. Taken together, the data suggested that ZYQL enhanced the transcriptional activity of transcription factors HSF-1 and SKN-1, which in turn increased oxidative/heat stress resistance to exert its anti-aging effect in C. elegans. Our results provide new insights into the beneficial effects and underlying mechanisms of ZYQL, which might be useful for further developing ZYQL into health or anti-aging beverages.

Abstract
To examine the metabolism of genipin-1-β-d-gentiobioside (GG), its distribution and biotransformation in vivo and in vitro were investigated. Urine, plasma, feces, and various organs were collected after oral administration of GG to normal rats and pseudo-germ-free rats to evaluate GG metabolism in vivo. GG was incubated with intestinal flora and primary hepatocytes in vitro to investigate microbial and hepatic metabolism. Using HPLC-Q-TOF-LC/MS, 11 metabolites of GG were absolutely or tentatively identified in terms possible elemental compositions, retention times, and characteristics of fragmentation patterns corresponding to eight biotransformations: deglycosylation, hydroxylation, sulfate conjugation, glucuronidation, hydrogenation, demethylation, glycosylation, and dehydration. Fewer metabolites were detected in pseudo-germ-free rats than in conventional rats. Moreover, geniposide and genipin were generated by the deglycoslation of intestinal bacteria. Geniposidic acid was detected in rat primary-hepatocyte incubation. This study first explores the metabolism of GG in vivo and in vitro. The results can aid the elucidation of PK profiles and clinical usage of gardenia fruit.
