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.
