Different chemotypes are described as anti-inflammatory. Among them the N-acylhydrazones (NAH) are highlighted by their privileged structure nature, being present in several anti-inflammatory drug-candidates. In this paper a series of functionalized 3-aminothiophene-2-acylhydrazone derivatives 5a-i were designed, synthesized and bioassayed. These new derivatives showed great anti-inflammatory and analgesic potency and efficacy. Compounds 5a and 5d stand out in this respect, and were also active in CFA-induced arthritis in rats. After daily treatment for seven days with 5a and 5d (50 µmol/Kg), by oral administration, these compounds were not renal or hepatotoxic nor immunosuppressive. Compounds 5a and 5d also displayed good drug-scores and low risk toxicity calculated in silico using the program OSIRIS Property Explorer.

不同的化学型被描述为具有抗炎作用。其中，酰腙（NAH）因其独特的结构性质而受到关注，存在于几种抗炎候选药物中。在本文中，设计、合成并测试了一系列功能化的 3-氨基噻吩-2-酰腙衍生物 5a-i。这些新衍生物表现出很强的抗炎和镇痛作用。在这方面，化合物 5a 和 5d 尤为突出，并且在 CFA 诱导的大鼠关节炎中也具有活性。经口给予 5a 和 5d（50 μmol/kg）每日治疗 7 天后，这些化合物没有肾毒性或肝毒性，也没有免疫抑制作用。化合物 5a 和 5d 还显示出良好的药物评分和低风险毒性，使用 OSIRIS Property Explorer 程序进行计算。
