Using Caenorhabditis elegans as the experimental model, researchers found that 0.15 mg/mL EP supplementation extended lifespan by a remarkable 33.33%. EP also significantly enhanced healthspan, improving physiological metrics such as head thrashing, body bending, and pharyngeal pumping by 24.37%, 22.33%, and 28.81%, respectively. Furthermore, EP reduced aging biomarkers-including lipofuscin and reactive oxygen species (ROS)-by up to 40.34%, while boosting overall antioxidant capacity (SOD increased by 53%, MDA decreased by 30.76%). Transcriptomic analysis identified 2196 differentially expressed genes (DEGs) out of 23 057 total identified genes, providing deep insights into the mechanisms underlying EP-mediated longevity. Crucially, EP upregulated genes responsible for unsaturated fatty acid biosynthesis (fat-7 and elo-4) to optimize cell membrane fluidity. Conversely, it downregulated genes linked to fatty acid β-oxidation (acs-2, acox-1.5, ech-9, hacd-1) and endogenous stress responses (sod-3, hsp-16.1, hsf-1). Validated via qRT-PCR, these shifts indicate that EP extends lifespan by fundamentally remodeling lipid metabolism and maintaining redox homeostasis. Ultimately, these findings highlight EP as a highly promising functional food ingredient for promoting healthy aging.","PeriodicalId":9878,"journal":{"name":"Chemistry & Biodiversity","volume":"23 9","pages":"e71648"},"PeriodicalIF":2.9,"publicationDate":"2026-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13539471/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148886383","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Motor performance was evaluated using the rotarod, cylinder, and open field tests. Brain levels of monoamines and cytokines as well as redox status were measured. WSMoL prevented the rotenone-related deficits in motor performance, which was accompanied by non-depleted dopamine and serotonin levels. WSMoL also mitigated the increase of IL-6, IL-17A, IFN-γ, and TNF-α. In addition, it prevented oxidative stress by avoiding the exacerbation of superoxide production, lipid peroxidation, and NADPH oxidase activity, while maintaining catalase, superoxide dismutase (SOD), and reduced glutathione (GSH) levels. The data show that D1 receptor-mediated signaling contributes to WSMoL effects. In conclusion, WSMoL attenuates motor deficits and neuroinflammation in a PD model, which supports its potential as a neuroprotective agent and warrants further mechanistic and translational studies.","PeriodicalId":9878,"journal":{"name":"Chemistry & Biodiversity","volume":"23 9","pages":""},"PeriodicalIF":2.9,"publicationDate":"2026-08-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/cbdv.71646","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148859996","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

UHPLC-MS/MS profiling identified 17 compounds in EA and 20 in EHA, with trans-cinnamic acid as the most abundant constituent (73.73 µg/g in EA and 84.02 µg/g in EHA), together with catechin, epigallocatechin, and six vitamins, vitamin C being the most abundant.

In the brine shrimp lethality assay on Artemia salina, used here as a preliminary cytotoxicity screen rather than an indicator of anticancer activity, both extracts displayed dose-dependent lethality. Exploratory molecular docking against DNA gyrase and enoyl-acyl carrier protein reductase suggested that catechin and epigallocatechin could potentially interact with these bacterial targets.
