Specialized pro-resolving mediators (SPMs), derived from polyunsaturated fatty acids, are crucial for actively terminating inflammation and restoring tissue homeostasis. Maresin 1 (MaR1), a prototypical SPM biosynthesized from docosahexaenoic acid (DHA), has emerged as a powerful modulator of pain. This review comprehensively synthesizes the current preclinical evidence, primarily derived from preclinical animal models, detailing the analgesic effects of MaR1 across a spectrum of pain models, including inflammatory, neuropathic, postoperative, osteoarthritis-related pain, etc. We dissect the multifaceted mechanisms underlying its efficacy, which extend beyond simple anti-inflammation. MaR1 exerts its effects by: (1) attenuating neuroinflammation including the suppression of glial (microglia and astrocyte) activation and reprogramming macrophage phenotypes; (2) directly modulating neuronal function by inhibiting nociceptive ion channels (e.g. TRPV1) and reversing central synaptic plasticity; and (3) promoting robust tissue repair, including peripheral nerve regeneration. These actions are mediated through potential specific receptors, notably G-protein-coupled receptor 37-like 1 (GPR37L1) on glial cells and retinoic acid-related orphan receptor α (RORA) on neurons. While MaR1 demonstrates significant therapeutic potential, challenges related to its pharmacokinetic instability and observed sex-dependent analgesic effects must be addressed for successful clinical translation. This review provides a comprehensive mechanistic framework supporting MaR1 as a next-generation therapeutic candidate for pain management, and outlines the core research directions to overcome key translational barriers for MaR1-based therapies.</p>","PeriodicalId":11290,"journal":{"name":"Drug Design, Development and Therapy","volume":"20 ","pages":"585597"},"PeriodicalIF":5.1,"publicationDate":"2026-04-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13128500/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147812424","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Studies have shown that hyperglycemia can promote the occurrence and progression of atherosclerosis by damaging vascular endothelial cells, macrophages, and vascular smooth muscle cells. In recent years, Chinese herbal medicines and their active ingredients have demonstrated unique advantages in preventing and treating high-glucose-induced vascular cell damage. Their mechanisms of action primarily encompass two aspects: firstly, regulating blood glucose through multiple pathways such as modulating the insulin signaling pathway, enhancing peripheral glucose uptake and utilization, and delaying intestinal carbohydrate absorption; secondly, intervening in key pathological processes such as high-glucose-induced vascular cell inflammation, cell death, phenotypic transformation, and metabolic reprogramming. This, in turn, slows down the progression of diabetes-related atherosclerosis. This article systematically elucidates the molecular mechanisms underlying hyperglycemia-induced damage to vascular endothelial cells, macrophages, and vascular smooth muscle cells. It also summarizes the protective mechanisms of Chinese herbal medicine active ingredients (albiflorin, salvianolic acid B, scutellarin, vitexin, hydroxysafflor yellow A, ginsenoside Rb1, maslinic acid, paeonol, citronellal, matrine, Panax notoginseng saponins, astragalus polysaccharides, 6-gingerol, and sodium tanshinone IIA sulfonate) and traditional Chinese medicine compounds (buyang huanwu decoction, guanxining tablets, and fufang zhenzhu tiaozhi) against vascular endothelial cells, macrophages, and vascular smooth muscle cells. The aim is to provide a theoretical basis for the prevention and treatment of diabetes-related atherosclerosis, as well as the development of related therapeutic drugs.</p>","PeriodicalId":11290,"journal":{"name":"Drug Design, Development and Therapy","volume":"20 ","pages":"602453"},"PeriodicalIF":5.1,"publicationDate":"2026-04-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13121073/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147765635","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
