Abstract
This study characterizes the steroidal saponin diosgenin by theoretical and experimental spectroscopic techniques. Theoretical simulations were performed using the DFT/B3LYP/6-311++G(d,p) basis set to simulate spectroscopic, structural and other properties. Optimized geometries from simulations and experiments showed strong agreement, with R2 value of 0.99846 for bond lengths and 0.88092 for bond angles. Vibrational spectra revealed distinctive peaks for the methyl, methylene, and methine groups in diosgenin. Solvent–solute interactions on the Frontier Molecular Orbitals (FMO), Molecular Electrostatic Potential (MEP) surfaces, and electronic spectra were analyzed, revealing insights into diosgenin’s behavior in different environments. The FMO energy gap shows that polar solvents like acetone, ethanol, and water have wider band gaps (6.22–6.23 eV) than non-polar solvents like benzene, chloroform, and toluene (6.17–6.20 eV), indicating stronger interactions with polar groups, enhanced stability, and reduced reactivity. NBO analysis shows substantial stabilization energy (14.71 kJ/mol) when electrons from oxygen’s (O1) lone pair are donated to the anti-bonding orbital of O2C15 through the transition of LP (2) → σ*. The carbon (C15) situated between oxygen (O1) and (O2) exhibits increased electronegativity (−1.65605 e), confirming the electronegativity of the oxygen atoms. Hirshfeld surfaces shows that the crystal structure is mainly influenced by H…H (90.7 %) interaction. Topological analyses revealed molecular interactions and chemical bonding within diosgenin, highlighting its diverse chemical functionalities. Furthermore, molecular docking and ADME predictions underscores diosgenin’s potential biological activity against human hexokinase (−8.09 kcal/mol) and phosphofructokinase (−8.35 kcal/mol), suggesting its efficacy as an antitumor drug.
期刊介绍:
Spectrochimica Acta, Part A: Molecular and Biomolecular Spectroscopy (SAA) is an interdisciplinary journal which spans from basic to applied aspects of optical spectroscopy in chemistry, medicine, biology, and materials science.
The journal publishes original scientific papers that feature high-quality spectroscopic data and analysis. From the broad range of optical spectroscopies, the emphasis is on electronic, vibrational or rotational spectra of molecules, rather than on spectroscopy based on magnetic moments.
Criteria for publication in SAA are novelty, uniqueness, and outstanding quality. Routine applications of spectroscopic techniques and computational methods are not appropriate.
Topics of particular interest of Spectrochimica Acta Part A include, but are not limited to:
Spectroscopy and dynamics of bioanalytical, biomedical, environmental, and atmospheric sciences,
Novel experimental techniques or instrumentation for molecular spectroscopy,
Novel theoretical and computational methods,
Novel applications in photochemistry and photobiology,
Novel interpretational approaches as well as advances in data analysis based on electronic or vibrational spectroscopy.
