Therefore, there is urgent necessity for the exploration of safer alternatives, particularly cyclooxygenase-2 (COX-2) inhibitors. This study aimed to address this issue through the synthesis and evaluation of 19 new chalcone derivatives (<strong>2a-m</strong> and <strong>4a-f</strong>) for their <em>in vitro</em> anti-inflammatory activity against various biotargets including iNOS, COX-2, 5-LOX, PGE2, and TNFα. Moreover, these compounds showed moderate to strong anti-inflammatory activity in the carrageenan rat paw edema test. Compounds <strong>2a</strong>, <strong>2f</strong>, <strong>2</strong> <strong>h</strong>, <strong>2</strong> <strong>m</strong>, and <strong>4b</strong> are promising candidates for the treatment of inflammatory diseases. In particular, compound <strong>4b</strong> was demonstrated to be the most effective derivative as a nitric oxide release inhibitor, exhibiting a 61.7 % inhibition rate. It exhibited substantial selectivity for COX-2 (IC<sub>50</sub> = 1.933 μM) compared to COX-1 (IC<sub>50</sub> = 5.526 μM). Compound <strong>4b</strong> exhibited notable inhibitory activity against 5-LOX (IC<sub>50</sub> = 2.112 μM) and demonstrated considerable inhibitory activity against iNOS, PGE2, and TNF-α biotargets in LPS-stimulated RAW cells, with IC<sub>50</sub> values of 114.18, 37.13, and 58.15 nM, respectively. The <em>in vivo</em> anti-inflammatory effects demonstrated the significant efficacy of compound <strong>4b</strong>, as evidenced by a notable edema inhibition rate of 37.05 %, along with minimal ulcerogenic activity observed in the histopathological findings. <em>In silico</em> experiments demonstrated that the intermolecular contacts of the most active chemical <strong>4b</strong> with the biotargets COX-2, 5-LOX, and iNOS were analyzed by docking, revealing significant binding interactions. The stability of the interactions between compound <strong>4b</strong> and the targets COX-2, 5-LOX, and iNOS was assessed using a standard 100 ns atomistic dynamic simulation method. Various parameters derived from MD simulation trajectories were adjusted and validated to confirm the stability of the generated complexes under dynamic settings. Ultimately, compound <strong>4b</strong> exhibited favorable physicochemical properties and satisfactory drug-likeness, indicating its potential as an oral anti-inflammatory agent, warranting additional structure-activity relationship investigation and optimization.</div></div>","PeriodicalId":257,"journal":{"name":"Bioorganic Chemistry","volume":"161 ","pages":"Article 108540"},"PeriodicalIF":4.5,"publicationDate":"2025-04-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143887212","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
