physicochemical, elemental analysis, and spectral data. The title compounds were screened for in vivo acute anti-inflammatory and analgesic activities at a dose of 200 mg/kg bw. Among the series, four compounds 7c, 7e, 7f, and 7h were found to possess a significant anti-inflammatory and analgesic activity profile. In addition, these compounds were also found to possess a less degree of ulcerogenic potential
通过适当取代基之间的缩合反应合成了一系列新的3-[(5-取代-1,3,4-恶二唑-2-基-硫基)乙酰基] -2H-铬-2--2-酮(7a – i)。来自多种现有NSAID的5-取代的1,3,4-恶二唑基-2-硫酮(4a – i)和3-(2-溴乙酰基)-2H-铬-2--2-酮(6)在存在下回流下乙醇钠。根据理化,元素分析和光谱数据确定了合成化合物的结构。以200mg / kg体重的剂量筛选标题化合物的体内急性抗炎和镇痛活性。在该系列中,四种化合物7c,7e,7f发现7h和7h具有明显的抗炎和镇痛活性。另外,与标准的NSAID相比,还发现这些化合物具有较小程度的致溃疡潜力。
