Spectroscopic, electronic and chemical properties and molecular docking simulations of ethyl-2-(4-ethoxybenzylidene)-7-methyl-3-oxo-5-(4-benzyloxyphenyl)-2,3-dihydro-5H-[1,3] thiazolo [3,2-a]pyrimidine-6-carboxylate (EMTP) have been extensively studied and discussed on DFT calculations. Using potential energy scans for various rotable bonds to obtain the lowest energy conformer, conformational analysis was achieved. Electronic, chemical, and drug-likeness properties are analyzed. Charge delocalization patterns and second-order perturbation energies of the most interacting natural bond orbitals have also been computed and predicted from wavefunction analysis. To understand the interaction between receptor and inhibitor EMTP ligand drug, we have performed molecular docking and molecular dynamics (MD) simulations. Docking binding affinities and the formation of a good number of hydrogen bonds suggest that EMTP appears to be a promising drug for the selected inhibitors.
