    Structural, Bioactivity, Molecular Docking, Spectroscopic and Electronic Properties of a Synthesized Meldrum's Acid Derivative
    (Wiley-V C H Verlag Gmbh, 2021) Gokce, Halil; Alpaslan, Gokhan; Kaya, Serdal; cakir, Nezaket
    The molecular structure, tautomeric forms (enol and keto), spectroscopic and electronic properties of a synthesized Meldrum's acid derivative were studied by using the experimental (SCXRD, FT-IR, NMR and UV) and computational (DFT/B3LYP/6-311++G(d,p) level) methods. Hirshfeld surface analysis were used to investigate the presence of inter-molecular interactions within crystal packing. The biological activity, drug-likeness and interactions between the target protein and the ligand compound were studied by in silico ADME and molecular docking methods. The non-linear optical (NLO) activity of the compound was determined with static computations of dipole moment, polarizability and first-order hyperpolarizability values. Thermo-chemical features were theoretically analyzed for both enol forms. Comparatively with the experimental vibrational frequencies, detailed assignments and interpretations of the computed harmonic vibrational wavenumbers were carried out in PED. The certain structural form at the room temperature of the compound was analyzed by H-1- and C-13-NMR chemical shift studies. The UV, HOMO and LUMO analyses were studied to research electronic properties of the compound. The nature, structure and existence of the hyper-conjugative interaction for the O-H...O intra-molecular hydrogen bonding in two enolic forms were investigated with Natural Bond Orbital (NBO) analysis. The reactive sites were obtained from atomic charges and Molecular Electrostatic Potential (MEP) map.
