Abstract

Schiff bases have advanced physical, chemical, and medicinal properties, making them strong biological agents. Comparable FTIR, UV-VIS, 1HNMR, 13CNMR spectra confirmed the successful formation of N-N-(1,2-Phenylene)bis(1-(4-bromophenyl)methanimine) (CS3) compound. Geometry was optimized using DFT with B3LYP/cc-pVDZ basis set. Obtained energy gap of the compound was 2.07 eV. Carbon and oxygen atoms were electrophilic, according to molecular electrostatic potential analysis. Mulliken charge analysis found that C atoms have + ve and -ve charges, H atoms have only positive charges, while Br, O, and N atoms have only -ve charges. The ELF analyzed the molecule and found that the atoms of C, N, and Br all had delocalized electron density. The wave function LOL identified localized orbital positions in the hydrogen atoms. RDG maps provided various non-covalent interactions. Synthesized compound was docked using PDB: 2ZM5 protein, with the lowest binding attractions obtained, are −5.44 (7BYE) kcal/mol.
