Biological Activity:
Palmatine hydrochloride (Palmatine chloride (6CI,7CI)) is a hydrochloride salt of palmatine which is a protoberberine alkaloid. Palmatine hydrochloride (Palmatine chloride (6CI,7CI)) has been used in the treatment of jaundice, dysentery, hypertension, inflammation, and liver-related diseases. [1] Palmatine inhibited carbachol-induced Ca2+-activated Cl− secretion and the carbachol-induced increase of intracellular Ca2+ concentration. Palmatine also inhibited cAMP-activated Cl− secretion induced by prostaglandin E2 (PGE2) or forskolin. Palmatine prevented the elevation of intracellular cAMP by forskolin. Determination of apical Cl− currents showed that palmatine suppressed the forskolin-stimulated, apical cAMP-activated Cl− current but not the carbachol-stimulated apical Ca2+-activated Cl− current.
