The butyryl galactose ester-modified coix component microemulsions (But-Gal-CMEs) was developed for enhanced liver tumor-specific targeting. The study was aimed to evaluate the hepatoma-targeting potential of But-Gal-CMEs in vitro and in vivo. But-Gal-CMEs with a uniform spherical shape exhibited a small

The natural flavonoid bergenin was directly immobilized onto carboxylic acid functionalized controlled pore glass (carboxy-CPG) at 95% yield. Immobilized bergenin was brominated via chloroperoxidase in aqueous solution and then transesterified with vinyl butyrate in diisopropyl ether by subtilisin carslberg (SC)
