Abstract
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.

Abstract
In this paper we report the design, synthesis and pharmacological evaluation of a series of N-phenyl-acetamide sulfonamide derivatives (5a-g), planned by structural modification on the prototype paracetamol (1). In this series (5a-g), compound LASSBio-1300 (5e; ID(50)=5.81 micromol/kg) stands out as a new non-hepatotoxic analgesic drug candidate. The increase of area, volume and electrostatic potential of paracetamol's analogues seems to be beneficial to the analgesic activity. Unlike paracetamol (1) and the other analogues (5a, 5d-g), compounds 5b and 5c presented an important anti-hypernociceptive activity associated to inflammatory pain.
