Spectral Characteristics, DFT Exploration, Electronic Properties, Molecular Docking and Biological Activity of 2E-1-(3-Bromothiophene-2-yl)-3-(1, 3-Benzodioxol-5-yl)Prop-2-en-1-One Molecule

Abstract

The FT–IR, FT–Raman and UV–Vis spectra of 2E-1-(3-bromothiophene-2-yl)-3-(1, 3-benzodioxol-5-yl)prop-2-en-1-one (BTBD) have been performed experimentally and simulated theoretically. The present investigation focuses mainly on quantum chemical calculations and the spectral characteristics of the molecule. The observed and theoretical wavenumbers have been assigned to respective vibrational modes through potential energy distribution (PED). The non-linear optical (NLO) properties have been explored through the calculation of the first hyperpolarizability of the BTBD compound. In the MEP map, it is evident that the negative site located the carbonyl group and the positive site over the CH2 group of 1, 3-benzodioxol, and all hydrogen atoms. From the HOMO–LUMO orbital investigation, the HOMO is caped on the C = O and C–C excluding the thiophene ring. The UV-Visible spectrum, the electronic properties which include wavelength, excitation energies, and oscillator strength were simulated via the DFT method. The antifungal ability of the molecule is predicted through in vitro evaluation toward four fungal strains. The NBO analysis confirms the hyper conjugative interaction and stabilization energy E (2). The in vitro anti-inflammatory activity was done via the protein denaturation assay method at various concentrations. Molecular docking studies were carried out to predict the active binding residues of the target.
