DFT, Molecular Docking, Molecular Dynamics Simulation, and Hirshfeld Surface Analysis of 2-Phenylthioaniline

Utilizing NMR (1H-NMR and 13C-NMR), FT-IR, UV-Visible, and quantum chemical approaches by using the DFT technique, experiments on 2-phenylthioanline were carried out. The B3LYP method and the 6-311++G(d,p) basis set were used to optimize the molecular structure and vibrational modes. The ideal binding parameters match up well with the experimental binding parameters. VEDA successfully finished the assignments concerning the distribution of potential energy. The GIAO method was used to calculate shifts in the 1H-NMR and 13C-NMR, and the outcomes were compared to experimental spectra. The TDDFT approach and the CPCM solvent model were used to examine electronic properties such as UV-Vis (in the gas phase, methanol, Acetone, and DCM), and the results were compared to experimental UV-Vis spectra. The HOMO/LUMO energy values provide sufficient proof of such. Molecular docking and dynamic simulations were carried out with a 2HI4 protein target and gave the best result among the three proteins.
