Off-White Solid | [Uses]
Protopine is a Ca2+ channel blocker and antiplatelet agent. Immunomodulator | [Definition]
ChEBI: A dibenzazecine alkaloid isolated from Fumaria vaillantii. | [General Description]
This substance is a primary reference substance with assigned absolute purity (considering chromatographic purity, water, residual solvents, inorganic impurities). The exact value can be found on the certificate. Produced by PhytoLab GmbH & Co. KG | [Enzyme inhibitor]
This photosensitive antiplatelet agent (FWfree-base = 353.37 g/mol; CAS 130-
86-9) from a number of plants, including the herb Fumaria officinalis and
opium, is a Ca2+ channel blocker. Protopine is commonly supplied
commercially as the hydroc2+hloride or the methiodide. Target (s) :
acetylcholinesterase; Ca channels; cation channel currents,
including ICa,L, IK, IK1, as well as INa; certain cytochrome P450 systems
; phospholipase; and thromboxane synthase. | [Purification Methods]
It crystallises from EtOH/CHCl3. The picrate has m ~240o(dec). [Beilstein 27 H 558, 17 I 568, 17 II 620, 17 III/IV 6881.] |
