Vibrational spectroscopic and molecular docking study of 4-Methylphenylquinoline-2-carboxylate

• IR, Raman spectra and NBO analysis were reported.
• The wavenumbers are calculated theoretically using Gaussian09 software.
• The wavenumbers are assigned using PED analysis.
• The geometrical parameters are in agreement with XRD data.
• Molecular docking is reported.

FT-IR and FT-Raman spectra of 4-Methylphenylquinoline-2-carboxylate were recorded and analyzed. The structure of the molecule has been optimized and structural characteristics have been determined by density functional theory. The geometrical parameters (DFT) are in agreement with the XRD results. HOMO and LUMO and other chemical properties are reported. Nonlinear optical properties are also reported. A detailed molecular picture of the title compound and its interactions were obtained from NBO analysis. The negative (red and yellow) regions of the MEP are related to electrophilic reactivity and the positive (blue) regions to nucleophilic reactivity, as shown in the MEP plot and the carbonyl group and the phenyl rings are observed as electrophilic. PASS analysis predicts that the 4-Methylphenylquinoline-2-carboxylate might exhibit anti-diabetic activity. Molecular docking results suggest that the compound might exhibit inhibitory activity against GPb.
