In this work, we reported the synthesis and evaluation of the analgesic, anti-inflammatory, and antipyretic properties of new 2-(6-nitro-benzo[1,3]dioxol-5-yloxy)-acetylhydrazone derivatives (3), designed exploring molecular hybridization and isosteric replacement approaches between nimesulide (1) and carbanalogue NAH series (2) developed at LASSBio. Target compounds were synthesized in very good yields
在这项工作中,我们报告了合成的新型2-(6-硝基-苯并[1,3]二恶酚-5-基氧基)-乙酰hydr衍生物(3)的止痛,抗炎和解热特性的评估。探索由LASSBio开发的尼美舒利(1)与碳糖类似物NAH系列(2)之间的分子杂交和等距替代方法。利用丰富的巴西天然产物黄樟脑(4)作为起始原料,以很高的收率合成了目标化合物。通过评估该系列产品的抗伤害感受特性,我们发现了一种新的有效止痛药和退热药原型,即名为LASSBio-891的NAH衍生物3c,它比标准的双嘧啶更有效。
