<i>N</i>′-(5-Bromofuran-2-carbonyl)isonicotinohydrazide

Abstract

N′-(5-bromofuran-2-carbonyl)isonicotinohydrazide (1) was obtained in the form of a colorless solid from the 2-methyl-6-nitrobenzoic anhydride (MNBA)/4-dimethylaminopyridine (DMAP)-catalyzed reaction of 5-bromofuran-2-carboxylic acid and isoniazid in dichloromethane at room temperature with a yield of 83%. The structure of N′-(5-bromofuran-2-carbonyl)isonicotinohydrazide (1) was elucidated using 1H NMR, 13C NMR, FTIR, and high-resolution mass spectrometry. Molecular docking screening of the title compound (1) on cyclooxygenase-2 (COX-2) protein (PDB ID: 5IKR) indicated that compound (1) has a good binding affinity, suggesting that further structure optimization and in-depth research can be carried out on compound (1) as a potential COX-2 inhibitor.
