Abstract
A new Schiff base (E)2-hydroxy-5-(((4-(N-pyrimidin-2-yl)sulfamoyl)phenyl)imino)methyl benzoic acid (5FSADA) compound was synthesized by condensation of 5-formyl salicylic acid and sulfadiazine, and the product formed was characterized using FTIR and UV–Visible spectroscopy. The geometry was optimized using DFT. The FTIR were computed from DFT and is compared with experimental spectra, followed by detailed vibrational assignment, which shows that the experimental and simulated data is in close agreement. The UV–Vis spectrum calculated using TD-DFT, IEFPCM solvation model with DMSO as solvent. Wave function based properties like localized orbital locator, electron localization function and non-covalent interactions has been studied extensively. The physical properties (ADMET) of the compound 5FSADA indicated that the compound has excellent drug likeness and PASS studies showed that it has anti-infective properties, which is confirmed by a docking score of −9.0 kcal/mol.
