Therefore, identifying pharmacological compounds with antioxidant and anti-inflammatory properties is central to curbing hepatic diseases. Ebselen is a synthetic organoselenium compound with glutathione peroxidase (GPx)-like activity, demonstrating potent antioxidant and anti-inflammatory effects experimentally. Ebselen targets several molecular mechanisms involved in hepatic cellular injury. It maintains redox-sensitive signaling, neutralizes reactive free radicals, and regulates thiol-dependent enzymes in experimental models of drug-induced, ischemia-reperfusion, and metabolic liver diseases. Studies provided experimental evidence for Ebselen's role in suppressing lipid peroxidation, preserving mitochondrial dynamics, inhibiting inflammatory response, and protecting hepatocytes in cell lines as well as murine models of different liver injuries. Findings also reported an indirect effect on cellular demise and fibrogenesis through inhibiting the activation of hepatic stellate cells (HSCs) and decreasing collagen deposition. The hepatoprotective effects of Ebselen also extend to include reducing hepatic lipid accumulation and preventing steatosis induction in rodent models of liver fibrosis.

The present study aimed to evaluate the biological activities of honey samples collected from different regions of Kazakhstan through experimental assays and computational analyses of major honey-derived phenolic compounds. Ethanolic extracts of seven honey samples were prepared and assessed for extraction yield, total phenolic content, total flavonoid content (TFC), antioxidant activity using the DPPH radical scavenging assay, and anti-inflammatory activity using the albumin denaturation inhibition assay. In addition, five representative honey-derived phenolic compounds, namely fumaric acid, p-hydroxybenzoic acid, p-coumaric acid, trans-2-hydroxycinnamic acid, and chrysin, were subjected to comprehensive in silico analyses including ADME prediction, drug-likeness evaluation, toxicity assessment, and multitarget molecular docking. Extraction yields ranged from 6.8% to 8.7%. The highest total phenolic content was observed in sample B12 (80.1 ± 9.7 mg GAE/g extract), whereas the highest TFC was detected in sample B10 (6.8 ± 0.5 mg quercetin equivalent (QE)/g extract). DPPH radical scavenging activity revealed IC&lt;sub&gt;50&lt;/sub&gt; values ranging from 2.5 ± 0.1 to 5.6 ± 0.4 mg/mL, with samples B11, B12, and B10 exhibiting the strongest antioxidant activities. In the albumin denaturation assay, all extracts demonstrated concentration-dependent anti-inflammatory activity, with inhibition percentages reaching 33.9% ± 2.0% at 100 mg/mL. The ADME analysis revealed that all investigated compounds exhibited favorable drug-likeness properties and high predicted gastrointestinal (GI) absorption. Chrysin demonstrated the highest lipophilicity and receptor-binding potential, whereas p-coumaric acid and trans-2-hydroxycinnamic acid showed the most balanced pharmacokinetic profiles. Toxicity predictions performed using ProTox-3.0, pkCSM, and admetSAR indicated low risks of hepatotoxicity and nephrotoxicity, with no predicted neurotoxicity, respiratory toxicity, carcinogenicity, or mutagenicity for any of the compounds. Molecular docking analyses against multiple inflammation-related targets, including cyclooxygenase-2 (COX-2), inducible nitric oxide synthase (iNOS), nuclear factor kappa-B (NF-κB), tumor necrosis factor-alpha (TNF-α), interleukin-6 (IL-6), and protein kinase B (AKT1), demonstrated strong binding affinities, particularly for trans-2-hydroxycinnamic acid and chrysin. These compounds exhibited favorable interactions with several key mediators of inflammatory signaling, suggesting potential multitarget mechanisms of action.

The kidneys are particularly vulnerable to heat-induced injuries, with oxidative stress (OS) playing a central role in their pathogenesis. The process involves heat-induced mitochondrial dysfunction and stimulation of inflammatory pathways. This leads to the production of excessive reactive oxygen species (ROS) that eventually overwhelm the kidney's natural antioxidant defenses. The resultant OS directly damages lipids, proteins, and DNA in renal tubular cells, a condition that is worsened by systemic inflammation and renal hypoxia. Although cells initially activate protective mechanisms involving heat shock proteins (HSPs) to preserve mitochondrial integrity, prolonged heat exposure undermines these defenses, increasing stress and triggering apoptotic pathways. This article focuses on the impact of HS on kidney health and the role of OS in the pathogenesis of heat-induced kidney injuries. Key markers of heat-induced OS, such as lipid peroxidation products (e.g., malondialdehyde [MDA], F<sub>2</sub>-isoprostanes, 4-hydroxynonenal [4-HNE], and 8-hydroxy-2'-deoxyguanosine [8-OHdG]) and their effects on hematological indices and inflammatory response are highlighted. Ultimately, clarifying these specific mechanisms is essential to guide the development of early diagnostic tools and targeted treatments. This will help to reduce kidney damage, especially in vulnerable populations. We suggest that strategies such as adequate hydration, educating vulnerable groups on signs of heat strain, wearing light clothing, and heat acclimatization can mitigate the adverse effects of the rising global temperatures on kidney health.</p>","PeriodicalId":19657,"journal":{"name":"Oxidative Medicine and Cellular Longevity","volume":"2026 1","pages":"e1708417"},"PeriodicalIF":0.0,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13392506/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148562592","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

An analysis of 49 scientific articles published between 2015 and 2025 was conducted using descriptors including \"skin aging,\" \"mitochondrial dysfunction,\" \"oxidative stress,\" and \"cutaneous senescence,\" and articles were retrieved from PubMed, Scopus, and ScienceDirect. Additional research was conducted using terms related to therapeutic interventions, including \"mitochondrial therapies AND skin aging OR cutaneous aging.\" Original research articles were included based on thematic relevance, recency, and scientific rigor. The reviewed studies suggest that oxidative stress, mainly from mitochondrial metabolism, is a primary cause of skin cell senescence. Mitochondrial dysfunction emerges as a central mechanistic hub linking oxidative stress, mitochondrial genome instability, chronic low-grade inflammation (inflammaging), and the senescence-associated secretory phenotype (SASP) to age-related structural and functional skin alterations. Mitochondria maintain skin homeostasis through cell proliferation, differentiation, and genetic material synthesis. With advancing age, mitochondrial DNA copy number declines significantly, while reactive oxygen species production increases, thereby compromising cellular energy metabolism. Emerging mitochondrial-targeted therapeutic strategies, including nicotinamide adenine dinucleotide (NAD<sup>+</sup>) precursors, coenzyme Q10 supplementation, senolytics, and modulators of mitochondrial quality control, show promising effects on skin aging parameters in preclinical and early clinical studies. However, current evidence is based on small clinical trials with short follow-up periods, and long-term safety data remain limited. Therefore, while mitochondria are not the sole source of oxidants, growing evidence indicates that oxidative stress-driven mitochondrial dysfunction represents a priority pathogenic mechanism in skin aging. The clinical translation of mitochondrial-targeted therapies represents an innovative opportunity for anti-aging strategies, although the validation of standardized biomarkers and longitudinal safety investigations remains critical for clinical implementation.</p>","PeriodicalId":19657,"journal":{"name":"Oxidative Medicine and Cellular Longevity","volume":"2026 1","pages":"e5140711"},"PeriodicalIF":0.0,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13175270/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147942343","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
