analgesic activity revealed that both prodrugs (MP1 and MP2) have shown significant reduction (81.67, 63.90 %) in writhing response produced by acetic acid as compared to parent drug MA (61.10 %). Both mutual prodrugs showed better maximum anti-inflammatory effects (71.43, 85.71 %) and for longer time as compared to parent drug MA (53.14 %). The synthesized prodrugs were also found to be very less irritating
在目前的研究工作中,我们报告了甲芬那酸(MA)和1,2二氢-1,5-二甲基-4-(1-甲基乙基)-2-苯基吡唑的新互药的合成,体外水解研究和药理学评价-3-一种旨在提高治疗效力并延缓胃肠源性不良反应的药物。合成的互酯前药(MP1和MP2)的结构通过IR,1 H NMR,13确认。通过TLC确认13 C NMR,质谱及其形成。通过元素分析确定了合成化合物的纯度。用乙酸诱导的扭体法测试标题化合物的镇痛活性。通过角叉菜胶诱导的大鼠爪水肿方法和致溃疡性测试抗炎活性。对镇痛活性的研究表明,与母体药物MA(61.10%)相比,前药(MP1和MP2)均显示出乙酸产生的扭体反应显着降低(81.67,63.90%)。与母体药物MA(53.14%)相比,两种互用前药均显示出更好的最大抗炎作用(71.43,85.71%),并且具有更长的时间。还发现合成的前药比母体药物对胃粘膜的刺激性小得多。在pH 1.2的模拟胃液(SGF)和pH
