Quantum Computational, Spectroscopic, NHO and Molecular Docking Studies on 1-Methyl-nicotinamide (MNA): An Antithrombotic, Anti-inflammatory, Gastroprotective and Vasoprotective Compound

Abstract

In present work, 1-methylnicotinamide (1-MNA) has been investigated theoretically by density functional theory approach and investigated its vibrational spectroscopy. To complete the structure optimization, determination of vibrational frequencies and other valuable parameters, B3LYP method used with the 6-311++G(d,p) basis set. Atoms in molecules theory (AIM) had been used to evaluate ellipticity, isosurface projection by electron localization function and binding energies. The IR and Raman spectra have also been calculated computationally. NBO analysis employed to determine interactions of donor and acceptor. Fukui functions and molecular electrostatic potential (MEP) showed reactive regions of the molecule. UV-vis spectrum calculated using TD-DFT/PCM methods with different solvents. Thermodynamic properties like free energy, enthalpy and entropy with various temperature were calculated. By the use of the electrophilicity index, the probability of the bioactive nature of the molecule was proved theoretically. Protein-ligand interactions calculated and established by molecular docking. The biological investigations for druglikeness also employed for the (1-MNA).
