Phloretin, 250 mg

Background: Phloretin is a cell-permeable protein kinase C (PKC) inhibitor (IC50 = 20-50 µM) and a PGF2a receptor antagonist. In astrocytes, these receptors are linked to phospholipase C, thus affecting phosphoinositide hydrolysis and intracellular Ca2+ levels. It inhibits L-type Ca2+ channel activity. Phloretin also inhibits myo-inositol uptake and serve as a potent inhibitor of 5'-iodothyronine deiodinase.
