The stable conformer of the synthesized 1-phenylethanone-O-pyropyl oxime ether (PEPOE) has been determined by potential energy profile analysis. All the structural parameters of PEPOE were identified by Density Functional Theory (DFT) with B3LYP method and 6-311++G(d,p) basis set. The spectroscopic properties, FTIR, NMR and UV-Vis results have been theoretically calculated and compared with experimental data. The highest occupied molecular orbital (HOMO), lowest unoccupied molecular orbital (LUMO) energies and the electron density distribution were performed by same level.The heat capacity, entropy, and enthalpy of the PEPOE have been calculated at temperature range from 100 to 1000 C. In addition, the molecular docking studies with DNA and Human Serum Albumin (HSA) structures have been performed to find the most preferred binding mode of the ligand inside the DNA and HSA cavity. As a result of these studies, the binding free energies of DNA and HSA have been calculated as -20.92 and -26.78 kJ/mol, respectively. The results show that these calculations are valuable for providing insight into molecular properties of the oxime ether compounds.

In this work, quantum chemical properties of 1-naphthalen-2-yl-ethanone-O-propyl-oxime (NEOPO) molecule which may be biologically active have been presented as a structural, spectroscopic, electronic and molecular docking. All quantum chemical studies were performed by density functional theory (DFT) with the B3LYP / 6-311++G(d,p) method and basis set. The spectroscopic properties, atomic charges, HOMO-LUMO molecular orbitals, chemical reactivity and molecular electrostatic potential (MEP) were investigated as theoretically. The spectroscopic properties have been supported as experimentally. In addition, the Autodock/Vina program was used for molecular docking studies and the binding free energies were calculated as-27.20 and-34.73 kJ/mol for DNA-molecule and protein-molecule interactions, respectively.
