General description

Protopine is a celandine alkaloid and a bioactive compound associated with the plant families including fumariaceae, berberidaceae and papaveraceae. It is metabolized by demethylenation in the presence of the cytochrome enzymes cytochrome P450 family 2 subfamily d polypeptide 1 (CYP2D1) and cytochrome P450 family 2 subfamily c polypeptide 11 (CYP2C11).

Application

Protopine 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.

Biochem/physiol Actions

Protopine possesses anti-parasitic, antimicrobial and anti-inflammatory property. It mediates mitotic arrest by favoring tubulin polymerization. Protopine elicits anti-invasive effects in breast cancer tumor progression.. It also provides protection against oxidative stress-induced cell death.
Protopine hydrochloride is a Ca2+ channel blocker and antiplatelet agent.

Caution

Protect from light.

pH-zone-refining counter-current chromatography was successfully applied to the separation of alkaloids from a crude extract of Corydalis decumbens (Thunb.) Pers. using a multilayer coil planet centrifuge (CPC). The experiment was performed with a two-phase solvent system composed of methyl tert-butyl

S-Adenosyl-l-methionine:tetrahydroprotoberberine cis-N-methyltransferase (EC 2.1.1.122) catalyzes the conversion of (S)-stylopine to the quaternary ammonium alkaloid, (S)-cis-N-methylstylopine, as a key step in the biosynthesis of protopine and benzophenanthridine alkaloids in plants. A full-length cDNA encoding a protein exhibiting 45 and 48% amino

The present investigation demonstrates the hepatoprotective potential of 50% ethanolic water extract of whole plant of Fumaria indica and its three fractions viz., hexane, chloroform and butanol against d-galactosamine induced hepatotoxicity in rats. The hepatoprotection was assessed in terms reduction
