Abstract
- In this study, the molecular interaction of silybin with hyaluronidase was investigated by spectroscopic methods and molecular docking. It was found that silybin had strong ability to quench the intrinsic fluorescence of hyaluronidase by a static quenching procedure. The binding constants were obtained at three temperatures (293, 298, and 310 K). The results of synchronous fluorescence and three-dimensional fluorescence and molecular docking showed that silybin bound into the hyaluronidase cavity site and the binding of silybin to hyaluronidase could induce micro-environmental and conformational changes in hyaluronidase, which resulted in the reduced hyaluronidase activity. The thermodynamic parameter analysis and molecular docking experiments revealed that all types of non-covalent interaction, including hydrogen bonding interaction, van der Waals forces, hydrophobic interaction, and electrostatic interaction were present in the binding process of silybin with hyaluronidase. The results obtained here will provide direct evidence at a molecular level to understand the mechanism of the inhibitory effect of silybin against hyaluronidase. [ABSTRACT FROM AUTHOR]
