were tested in vivo for their anti-inflammatory activity. All the compounds tested showed anti-inflammatory activity. The compounds which showed activity comparable to the standard drug ibuprofen were screened for their analgesic, ulcerogenic and lipid peroxidation activities. Seven (3c, g, i, j, m, o, p) out of 23 new compounds showed very good anti-inflammatory activity in the carrageenan-induced rat
本文报道了各种含1,3,4-氧杂二唑核的芳酰基丙酸衍生物的合成和生物学评估。化合物(3a - w)是通过在POCl 3的存在下用各种芳酸酰肼处理将3-芳酰基丙酸环化成1,3,4-恶二唑核合成的。新化合物的结构得到IR,1 H NMR和MS数据的支持。在体内测试了这些化合物的抗炎活性。所有测试的化合物均显示出抗炎活性。筛选显示出与标准布洛芬可比的活性的化合物的镇痛,促溃疡和脂质过氧化活性。七(3c,g在23种新化合物中,i,j,m,o,p)在角叉菜胶诱导的大鼠爪水肿试验中显示出非常好的抗炎活性,而致溃疡的作用却很小。该化合物显示出较少的致溃疡作用,还显示出丙二醛产生减少(MDA),其是脂质过氧化的副产物之一。化合物3i和o分别显示出90.50和88.88%的脚掌水肿抑制作用,69.80和66.25%的醋酸抗扭伤保护作用以及严重程度指数分别为0.7和0.65,而布洛芬的保护值分别为90.12、72
