The current study was designed to investigate the potential of a synthetic therapeutic agent for better management of pain and inflammation, exhibiting minimal to non-existent ulcerogenic effects. The effect of 1-(2-chlorobenzoyl)-3-(2,3-dichlorophenyl) thiourea was assessed through model systems of nociception and anti-inflammatory activities in mice. In addition, the ulcerogenic potential was evaluated in rats using the NSAID-induced pyloric ligation model, followed by histopathological and biochemical analysis. The test was conducted on eight groups of albino rats, comprising of group I (normal saline), groups II and III (aspirin® at doses of 100 mg/kg and 150 mg/kg, respectively), groups IV and V (indomethacin at doses of 100 mg/kg and 150 mg/kg, respectively), and groups VI, VII, and VIII (lead-compound at 15 mg/kg, 30 mg/kg and 45 mg/kg doses, respectively). Furthermore, molecular docking analyses were performed to predict potential molecular target site interactions. The results showed that the lead-compound, administered at doses of 15, 30, and 45 mg/kg, yielded significant reductions in chemically and thermally induced nociceptive pain, aligning with the levels observed for aspirin® and tramadol. The compound also effectively suppressed inflammatory response in the carrageenan-induced paw edema model. As for the ulcerogenic effects, the compound groups displayed no considerable alterations compared to the aspirin® and indomethacin groups, which displayed substantial increases in ulcer scores, total acidity, free acidity, and gastric juice volume, and a decrease in gastric juice pH. In conclusion, these findings suggest that our test compound exhibits potent antinociceptive, anti-inflammatory properties and is devoid of ulcerogenic effects.
本研究旨在探索一种合成治疗剂在疼痛和炎症管理方面的潜力,该治疗剂表现出最小至不存在的溃疡形成作用。通过小鼠的疼痛和抗炎活性模型系统评估了 1-(2-氯苯甲酰基)-3-(2,3-二氯苯基)硫脲的作用。此外,还通过 NSAID 诱导的幽门结扎模型在大鼠中评估了溃疡形成潜力,随后进行了组织病理学和生化分析。该试验在八组白化大鼠上进行,包括组 I(生理盐水)、组 II 和组 III(阿司匹林®剂量分别为 100mg/kg 和 150mg/kg)、组 IV 和组 V(吲哚美辛剂量分别为 100mg/kg 和 150mg/kg)以及组 VI、组 VII 和组 VIII(先导化合物剂量分别为 15mg/kg、30mg/kg 和 45mg/kg)。此外,还进行了分子对接分析以预测潜在的分子靶标相互作用。结果表明,先导化合物在 15、30 和 45mg/kg 剂量下可显著减轻化学和热诱导的疼痛,与阿司匹林®和曲马多的水平相当。该化合物还能有效抑制角叉菜胶诱导的足肿胀模型中的炎症反应。至于溃疡形成作用,与阿司匹林®和吲哚美辛组相比,化合物组没有明显的改变,阿司匹林®和吲哚美辛组的溃疡评分、总酸度、游离酸度和胃液量显著增加,胃液 pH 值降低。总之,这些发现表明,我们的测试化合物具有有效的镇痛、抗炎作用,且没有溃疡形成作用。
