Abstract
This paper presents the synthesis of a novel chalcone derivative, and its molecular structure has been determined by NMR and single-crystal X-ray diffraction analysis. The molecules are connected via OH⋅⋅⋅O, CH⋅⋅⋅O, and CH⋅⋅⋅S hydrogen bonds along with CH⋅⋅⋅π and π⋅⋅⋅π interactions. Hirshfeld surface studies have been conducted to comprehensively quantify the patterns of intermolecular interactions. DFT calculations provided insights into the nature of the molecule, including frontier molecular orbital, ADCH charge, Molecular Electrostatic Potential and Natural Bond Orbitals analysis using the optimized structure by B3LYP/6–311 G (d, p) level. The calculated HOMO-LUMO gap (3.23 eV) indicates decent softness and reactivity of the target molecule. The molecular docking studies reveal that the target compound exhibits a high binding affinity with Human Cathepsin D (CatD), with a docking score of -7.58 kcal/mol. The assessment of drug-likeness properties and ADMET (absorption, distribution, metabolism, excretion, and toxicity) profiles further support its potential as a potent CatD inhibitor candidate for medication development.
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.
