Molecular Structure
Chemical structure of Tricetin (3',4',5,5',7-pentahydroxyflavone)
The relationship between Tricetin's structure and its function represents a perfect example of nature's precision engineering. The abundance of hydroxyl groups enables Tricetin to effectively neutralize harmful free radicals, making it a potent antioxidant 3 . Additionally, these chemical features allow Tricetin to interact with numerous cellular proteins and enzymes, modulating their activity in ways that can counter disease processes.
Molecular docking studies have revealed that Tricetin fits snugly into the active sites of various disease-related proteins, including PIM1 kinase and FLT3—both important targets in cancer treatment 6 . This structural compatibility with multiple therapeutic targets underpins Tricetin's potential as a multifaceted therapeutic agent capable of addressing complex diseases through several simultaneous mechanisms.
