Here we present a synthetic procedure, spectroscopic characterization and single-crystal X-ray structure for the nitro-reduced metabolite of the anti-inflammatory drug nimesulide, hereby referred to as NMS-NH2. The nitro-reduced metabolite was synthesized using the Bechamp reduction (iron powder under acidic media), leading to the conversion of the nitrobenzene group of nimesulide to an aniline. Mass spectrometry, infrared and nuclear magnetic resonance spectroscopies data are also provided for NMS-NH2, and discussed in comparison to nimesulide. NMS-NH2 was also evaluated in terms of its antibacterial activities, considering that the free -NH2 group could allow the compound to act as a dihydropteroate synthase inhibitor. NMS-NH2 had a modest antibacterial activity against P. aeruginosa (5.0 mg mL(-1)), which was not observed for NMS. (C) 2017 Elsevier B.V. All rights reserved. (AU)
