Description générale

Vinyl butyrate causes the transesterification of natural flavonoid bergenin immobilized onto carboxylic acid functionalized controlled pore glass.

Application

Vinyl butyrate was used as acyl donor in the synthesis of citronellyl esters (acetate, propionate, butyrate, caprate and laurate) using immobilized Candida antarctical ipase B.

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)

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
