jatrorrhizine

Jatrorrhizine (neprotin) is a protoberberine alkaloid isolated from Enantia chlorantha (Annonaceae) and other species. It was found to have antimicrobial and antifungal activity. It binds and noncompetitively inhibits monoamine oxidase (IC50 4 micromolar for MAO-A and 62 for MAO-B).

Jatrorrhizine hydrochloride is a compound extracted from the roots of Berberis vulgaris with neuroprotective, antimicrobial, antiplasmodial, and antioxidant activities.Jatrorrhizine hydrochloride is an orally active and selective inhibitor of acetylcholinesterase (AChE), which inhibits norepinephrine (NE) uptake. It inhibits the uptake of norepinephrine (NE).

Jatrorrhizine chloride (Neprotine chloride) is a potent and orally active uptake-2 transporter inhibitor. It exhibits a critical neuroprotective role in H2O2-induced apoptosis via inhibition of the MAPK pathway in HT22 hippocampal neurons.

Jatrorrhizine hydroxide, an alkaloid derived from Coptis chinensis, exhibits a range of biological activities including neuroprotective, antimicrobial, antiplasmodial, and antioxidant properties [1]. It acts as a potent and orally active inhibitor of acetylcholinesterase (AChE) with an IC50 value of 872 nM, demonstrating over 115-fold greater selectivity for AChE compared to butyrylcholinesterase (BuChE) [2]. Additionally, Jatrorrhizine hydroxide impedes the uptake of serotonin (5-HT) and norepinephrine (NE) by inhibiting uptake-2 transporters, further contributing to its pharmacological profile [3].
