Synthesis, spectroscopy, solvation effect, topology and molecular docking studies on 2,2′-((1,2 phenylenebis (azaneylylidene)) bis (methaneylylidene)) bis(4-bromophenol)

The 2,2′-((1,2 phenylenebis (azaneylylidene)) bis (methaneylylidene)) bis(4-bromophenol) (5BSOP) Schiff base was synthesized, characterized using different spectroscopic techniques, and the data are compared with predictions from DFT computations. The calculated energy values are -8.65 eV (HOMO) and -6.66 eV (LUMO), and the energy gap was found to be 1.99 eV. The reactive atom sites in the chemical are identified by MEP analysis. The locations of localized and delocalized orbitals are revealed through ELF and LOL surface maps. The sites of non-covalent interactions are exposed by RDG and NCI analysis. The possible inter and intra-molecular interactions were determined by NBO analysis and the highest stabilization energy observed was 40.07 kcal/mol. Biological performance as a HMGCS2 expression enhancer was predicted by Pass online studies. Molecular docking simulation with protein 706I having HMGCS2 expression inhibition characteristics revealed a stable receptor-ligand interaction pose at a binding energy of -4.74 kcal/mol. The interaction of the Phe61 amino acid chain of 706I with 5BSOP through conventional H-bond expressed a bond distance of 3.24 Å.

期刊介绍： The Journal of Molecular Structure is dedicated to the publication of full-length articles and review papers, providing important new structural information on all types of chemical species including: • Stable and unstable molecules in all types of environments (vapour, molecular beam, liquid, solution, liquid crystal, solid state, matrix-isolated, surface-absorbed etc.) • Chemical intermediates • Molecules in excited states • Biological molecules • Polymers. The methods used may include any combination of spectroscopic and non-spectroscopic techniques, for example: • Infrared spectroscopy (mid, far, near) • Raman spectroscopy and non-linear Raman methods (CARS, etc.) • Electronic absorption spectroscopy • Optical rotatory dispersion and circular dichroism • Fluorescence and phosphorescence techniques • Electron spectroscopies (PES, XPS), EXAFS, etc. • Microwave spectroscopy • Electron diffraction • NMR and ESR spectroscopies • Mössbauer spectroscopy • X-ray crystallography • Charge Density Analyses • Computational Studies (supplementing experimental methods) We encourage publications combining theoretical and experimental approaches. The structural insights gained by the studies should be correlated with the properties, activity and/ or reactivity of the molecule under investigation and the relevance of this molecule and its implications should be discussed.
