Synthesis, DFT study and bioactivity evaluation of new butanoic acid derivatives as antiviral agents

Abstract

In the present work, at first, density functional theory (DFT) calculations were utilized for the molecular design of the four new butanoic acid derivatives at B3LYP/6-31+G(d) level of theory. After DFT calculations, synthesis, FT-IR, 1H NMR, and 13C NMR spectra of corresponding molecules were presented. The NBO analysis and electronic properties of the four new synthesized butanoic acid (1, 2, 3, 4) were carried out to compare their stability and reactivity. Finally, the values of octanol/water partition coefficient (miLogP), the molecular polar surface area (TPSA), the number of atoms of the molecule (natoms), the number of hydrogen bond acceptors (nON), the number of hydrogen bond donors (nOHNH), the number of violations of the Ro5 (nviolations), the number of rotatable bonds (nrotb), the molecular volume (Vm), the molecular weight (MW) and bioactivity scores were estimated and discussed.
