Abstract
Current study is based on the biology-oriented drug synthesis (BIODS) of S-naproxen (NSAID) derivatives and the evaluation of their urease inhibitory potential. In this regard, a variety of S-naproxen derivatives 2–39 including hydrazide 1, Schiff bases 2–21, aroyl substituted hydrazides 22–24, sulfohydrazides 25–34, 2-mercapto oxadiazole 35, phenacyl substituted 2-mercapto oxadiazoles 36–39 were synthesized under the umbrella of BIODS by simple chemical transformation of its pharmacophoric carboxylic group. Compounds 1–39 were evaluated for in vitro urease inhibitory activity and most of them showed good to moderate inhibitory potential in the range of IC50 = 14.01 ± 0.23–76.43 ± 0.8 µM as compared to standard acetohydroxamic acid (IC50 = 27.0 ± 0.5 µM). Limited structure-activity relationship (SAR) was established in order to rationalize the participation of varying groups (R) in the inhibitory potential of compounds. Molecular docking study on all active compounds was also carried out to decipher the interactions detail of the ligand with the receptors of active site of enzyme.
