resveratrol
Overview
Resveratrol is a naturally occurring polyphenolic compound predominantly found in the skin of red grapes, berries, and peanuts. It is recognized for its antioxidant, anti-inflammatory, and potential anticancer properties. Resveratrol exerts its biological effects primarily through modulation of various signaling pathways, including the sirtuin 1 (SIRT1) pathway, which is implicated in cellular stress resistance and longevity. Its ability to activate the SIRT1 pathway links resveratrol to mechanisms of aging and metabolic regulation, making it a subject of interest in the study of age-related diseases and conditions such as type 2 diabetes and cardiovascular diseases.
Recent Publications Focus
Below is a summary of the newest research publications targeting resveratrol (sorted by publication date).
Recent research has extensively investigated resveratrol's neuroprotective potential across multiple neurodegenerative conditions. In Alzheimer's disease models, resveratrol administration activated autophagy-associated signaling pathways through AMPK/ULK1 and SIRT1/NF-κB mechanisms, reducing aging-related markers and attenuating reactive oxygen species production [42412302]. In a stroke model, resveratrol maintained blood–brain barrier integrity and modulated the sFRP4/Wnt signaling pathway, reducing infarct area and alleviating post-stroke cognitive impairment [42114733]. Notably, trans- and cis-isomers of resveratrol exhibited opposing effects on mitochondrial endonuclease G activity; cis-resveratrol treatment inhibited dopaminergic neurodegeneration in a Parkinson's disease model and improved motor symptoms [42296341]. These findings position resveratrol among the most promising natural agents for age-related neurological diseases [42216664].
Resveratrol's metabolic and anti-cancer applications have emerged as major research directions. Supplementation in high-fat diet-fed mice reduced body weight gain and improved glucose tolerance through β3-AR/AMPKα-related thermogenic signaling [42338132]. In cancer models, resveratrol demonstrated efficacy through multiple mechanisms: selenium nanocarrier formulations enhanced hepatocellular carcinoma inhibition [42165412], ROS-responsive prodrug nanoparticles achieved synergistic chemoimmunotherapy [42159189], resveratrol induced ferroptosis in pancreatic cancer by targeting a regulatory network involving HIF-1/TGF-β signaling [42142137], and bilosomal carriers enhanced cytotoxicity against colorectal cancer cell lines with four- to sixfold reductions in IC₅₀ values [42098560]. Bibliometric analysis identified resveratrol among the top phytochemicals investigated for hepatocellular carcinoma therapy [42061133].
Inflammatory and degenerative joint disorders have been targeted with resveratrol-based interventions. Resveratrol suppressed epithelial-mesenchymal transition, apoptosis, and pyroptosis in neurogenic bladder through AKT/mTOR/S6K pathway inhibition [42319380]. Selenium nanoparticle-enhanced resveratrol formulations potently suppressed pulmonary inflammation and fibrogenesis in a silicosis model via redox-mediated modulation of TLR4/NF-κB/NLRP3 signaling [42159899]. In intra-articular applications, acetalated dextran short fibers loaded with resveratrol reduced swelling and proinflammatory cytokines in gouty arthritis [41833923], while mesoporous silica nanoparticles co-loaded with ibuprofen and resveratrol preserved joint architecture and reduced inflammatory markers by 50–60% in osteoarthritis models [41839392].
To overcome resveratrol's inherent bioavailability limitations, researchers have developed diverse delivery innovations. A spray-dried inhalable formulation achieved improved pulmonary distribution with a lung-to-plasma AUC ratio of 282 compared to 77 for micronized forms, demonstrating excellent safety over 12 weeks of repeated administration [42366507]. Hydrophobic resveratrol derivatives enhanced intestinal permeability across Caco-2 cells while reducing Phase II metabolism-mediated sulfation and glucuronidation [41985089]. Synthetic chemistry approaches generated resveratrol dimers including δ-viniferin, ε-viniferin, and gnetin C with defined bioactivity profiles [42247673]. Multiple polymer and emulsion-based systems—including alginate mucoadhesive nanofibers for nasal delivery [42092661], cyclodextrin-epichlorohydrin-cyanoguanidine polymers for cartilage repair [42018663], oleogels enhancing bioaccessibility to 80–85% [41916217], and Pickering emulsions achieving 90% encapsulation efficiency [41832010]—addressed formulation challenges while enabling controlled or targeted release profiles across therapeutic applications.
