Vibrational spectroscopic studies, Fukui functions, HOMO-LUMO, NLO, NBO analysis and molecular docking study of (E)-1-(1,3-benzodioxol-5-yl)-4,4-dimethylpent-1-en-3-one, a potential precursor to bioactive agents

The FT-IR and FT-Raman spectra of (E)-1-(1,3-benzodioxol-5-yl)-4,4-dimethylpent-1-en-3-one were recorded and analyzed experimentally and theoretically. The observed experimental and theoretical wavenumbers were assigned using potential energy distribution. The NLO properties were evaluated by the determination of first and second hyperpolarizabilities of the title compound. From the frontier molecular orbital study, the HOMO centers over the entire molecule except the methyl groups, while the LUMO is over the entire molecule except the CH2 group with the dioxole ring and one of the methyl groups. From the MEP plot, it is evident that the negative region covers the carbonyl and C=C groups and the positive region is over CH2 groups. The Fukui functions are also reported. The calculated geometrical parameters are in agreement with the XRD results. From the molecular docking study, the docked ligand title compound forms a stable complex with the androgen receptor and gives a binding affinity value of -8.1 kcal/mol and the results suggest that the compound might exhibit inhibitory activity against androgen receptor.
