The anti-viral compound DPDS was synthesized and characterized, with comprehensive analysis performed through experimental results and computational methods. Various aspects of the compound, including vibrational properties, chemical reactivity, stability, and topological features were studied in detail. Additionally, molecular docking with SARS-CoV-2 proteins and drug likeness assessment were conducted.
Prospective Anti-viral compound 3, 5 Dimethyl Pyrazolium 3, 5 Dichloro Salicylate (DPDS) was synthesized and characterized using FT-IR, FT-Raman, UV and NMR spectra. To escort the experimental results, computational methods were performed using B3LYP with 6-311G (d, p) basis set expending Gaussian09w package to attain geometry of the molecule. Vibrational assignments for all the vibrational modes have been made of PED results obtained from SQM method. On contrary, FMO analysis, global chemical reactivity descriptors, Aromaticity and Natural charge analysis were studied. Molecular stability and bond strength have been inquired by executing NBO analysis. Topological features of DPDS were intended by MEP, ELF and LOL maps. UV-vis spectrum was predicted by TD-DFT method in gaseous phase and compared with the experimental spectrum for displaying the involved electronic transitions in the compound. The interactions within the DPDS molecule were investigated via RDG analysis. Molecular docking was performed with SARS-CoV-2 proteins and docking parameters were obtained. Drug likeness was carried out based on Lipinski's rule of five and the ADMET factors were also predicted. (c) 2021 Elsevier B.V. All rights reserved.
