Protopinhydrochlorid

BeschreibungProtopine is an alkaloid found in Berberidaceae, Ranunculaceae, Rutaceae, Fumariaceae, and Papaveraceae with diverse biological activities. It inhibits platelet aggregation induced by ADP, arachidonic acid (Item Nos. 90010 | 90010.1 | 10006607), platelet-activating factor (PAF), and collagen in rabbit platelet-rich plasma at a concentration of 100 μM. Protopine inhibits contraction of isolated rat thoracic aorta induced by norepinephrine and is a non-selective inhibitor of ICa, IK, IK1, and INa in guinea pig ventricular myocytes. Protopine inhibits the growth of H. pylori with an MIC50 value of 100 μg/ml. It reduces growth of PC3 and DU145 prostate cancer cells in a dose-dependent manner via induction of mitotic cell cycle arrest. Protopine (0.005 mg/kg) increases latency to first seizure in a mouse model induced by pentylenetetrazole .

VerwendenProtopine hydrochloride may be used in the calibration curve preparation for the quantification of alkaloids from Fumaria capreolata using liquid chromatography coupled to diode array detection and electrospray ionization tandem mass spectrometry (LC-DAD-MS) and tandem mass spectrometry(MS/MS). It may also be used as an alkaloid in cytotoxicity and permeability studies carcinogenic cell lines.
