Abstract
AbstractA new series of 2-(4-(4-aminophenylsulfonyl) phenylamino)-3-(thiophen-2-ylthio)naphthalene-1,4-dione derivatives (3a-3n) were synthesized and characterized by spectral techniques. To understand the interaction of binding sites with bacterial protein receptor, the docking study was performed by the GLIDE program and compound N-(4-(4-(1,4-dioxo-3-(thiophen-2-ylthio)-1,4-dihydronaphthalen-2-ylamino)phenylsulfonyl)phenyl)-3-methylbenzamide (3b) exhibited good glide and E model scores of −5.89 and −94.90, respectively. Moreover among all the molecules studied including the standards used, namely Sparfloxacin (4.8 μg/mL) and Norfloxacin (no inhibition observed) for their antibacterial property, compound N-(4-(4-(1,4-dioxo-3-(thiophen-2-ylthio)-1,4-dihydronaphthalen-2-ylamino)phenylsulfonyl)phenyl)-4-nitrobenzamide (3e) exhibited the lowest minimum inhibitory concentration (MIC) value of 1.3 μg/mL against Proteus vulgaris.
