Spectral characterizations, Hirshfeld surface analysis and molecular docking studies of new novel NLO 2-(3,4-Dimethoxyphenyl)-3-hydroxy-4H-chromen-4-one

Abstract

The molecular structure of the compound, spectroscopic investigations (FT-IR, FT-Raman, and NMR) and the frontier energy level analysis of 2-(3,4-Dimethoxyphenyl)-3-hydroxy-4H-chromen-4-one (DMP3H), have been all examined using density functional theory (DFT) methods. Comparisons are made between predicted DFT geometrical parameters and experimental values and also the same performed between the theoretical vibrational wavenumbers and observed data. Chemical reactivity of DMP3H has been studied using DFT/PBEPBE approach that includes frontier orbital energies, optical characteristics and chemical descriptors. Additionally, the cytotoxic activity of the bioactive ligand has been checked against human cancer cell lines A549 and MCF-7 in vitro by the MTT assay. Hence, the docking and in vitro activity against cancer cell lines display positive results and the present ligand performance appears to be a promising way for anticancer agents with better efficacy.
