Currently, no effective treatment option is available. Aprepitant, a well-established chemotherapy antiemetic performing neurokinin-1 receptor antagonism, shows analgesic effects in some pain models. We studied aprepitant analgesic effects on the paclitaxel-induced neuropathic pain model in rats besides inflammatory markers assessment. Rats intraperitoneally received paclitaxel, reaching the cumulative paclitaxel dose of 8 mg/kg. Aprepitant was orally administered every alternate day between days 2 and 14, with a prescribed dosage of 10 or 20 mg/kg. The evaluation of mechanical allodynia and cold hyperalgesia involved the measurement of paw withdrawal threshold and acetone test score on days 0, 7, and 14. On day 14, paw licking latency was measured using a hot plate test before scarification and tissue collection for interleukin 1β, tumor necrosis factor α, and nuclear factor kappa B (NF-kB) evaluation. Paclitaxel induced neuropathy as indicated by a lowered hind paw withdrawal threshold in the Von Frey test, a higher score in the acetone test, and shortened hot plate latency. Aprepitant effectively alleviated cold and thermal hyperalgesia as well as mechanical allodynia. Moreover, aprepitant administration significantly reversed paclitaxel-mediated elevation of proinflammatory cytokines levels in dorsal root ganglia. In addition, aprepitant application suppressed the protein expression of NF-kB in the dorsal root ganglia of paclitaxel-treated rats, as revealed by western blot analysis. Aprepitant treatment ameliorates neuropathy induced by paclitaxel, which is associated with decreasing proinflammatory cytokines and NF-kB expression.</p>","PeriodicalId":11333,"journal":{"name":"Drug and Chemical Toxicology","volume":" ","pages":"1-10"},"PeriodicalIF":2.1,"publicationDate":"2024-11-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142616653","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

FTIR, <sup>1</sup>H, and <sup>13</sup>C NMR spectroscopic techniques were used to characterize it. Subsequently, computational techniques were used to assess various ADME factors, such as drug-likeness properties, bioavailability score, and adherence to Lipinski's rule. Finally, molecular docking experiments were conducted with the human topoisomerase α2 (TOP2A) protein to verify and validate the reliability and stability of the docking procedure. The results of the docking scores, which quantify binding affinity, indicated that these derivatives exhibited a stronger affinity for TOP2A.</p>","PeriodicalId":11333,"journal":{"name":"Drug and Chemical Toxicology","volume":" ","pages":"1175-1184"},"PeriodicalIF":2.1,"publicationDate":"2024-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140921526","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
