(-)-epicatechina gallato

Descrizione:

(-)-epicatechina gallato è un composto flavonoide appartenente alla classe delle catechine, che sono composti polifenolici presenti in varie piante, in particolare nelle foglie di tè. È caratterizzato dalle sue proprietà antiossidanti, che sono attribuite alla sua capacità di catturare i radicali liberi e chelare ioni metallici, contribuendo così ai suoi potenziali benefici per la salute. Il composto è un estere di galato di (-)-epicatechina, con un gruppo galoyl che ne migliora l'attività biologica. (-)-epicatechina gallato è noto per il suo ruolo nella promozione della salute cardiovascolare, nel miglioramento delle funzioni metaboliche e nell'esibizione di effetti anti-infiammatori. Inoltre, è stato studiato per le sue potenziali proprietà anticancro, poiché può inibire la crescita tumorale e indurre apoptosi nelle cellule tumorali. Il composto è solubile in acqua e solventi organici, rendendolo versatile per varie applicazioni in alimenti, prodotti farmaceutici e cosmetici. La sua presenza nel tè verde e in altre fonti vegetali evidenzia la sua importanza nella ricerca nutrizionale e sanitaria. In generale, (-)-epicatechina gallato è un composto di notevole interesse per le sue diverse attività biologiche e potenziali applicazioni terapeutiche.

Stability Light Sensitive
Applications One of the catechin isomers and a potent antioxidant that can modulate a wide range of membrane proteins. Its bilayer-modifying potency was tested using gramicidin A (gA) channels as probes. All the catechins alter gA channel function and modify bilayer properties, with a 500-fold range in potency. The gallate group causes current block, as evident by brief downward current transitions.
