Jatrorrhizine is a protoberberinealkaloid found in some plant species, such as Enantia chlorantha (Annonaceae).[1] Synonyms that may be encountered include jateorrhizine, neprotin, jatrochizine, jatrorhizine, and yatrorizine.
Bioactive effects
Jatrorrhizine has been reported to have antiinflammatory effect,[2] and to improve blood flow and mitotic activity in thioacetamide-traumatized rat livers.[3] It was found to have antimicrobial[4] and antifungal[5] activity. It binds and noncompetitively inhibits monoamine oxidase (IC50 = 4 μM for MAO-A and 62 μM for MAO-B)[6] It interferes with multidrug resistance by cancer cells in vitro when exposed to a chemotherapeutic agent.[7] Large doses (50–100 mg/kg) reduced blood sugar levels in mice by increasing aerobic glycolysis.
Derivatives of jatrorrhizine (notably 3-alkoxy derivatives, and specifically 3-octyloxy 8-alkyljatrorrhizine derivatives such as 3-octyloxy 8-butyljatrorrhizine) have been synthesized and found to have much stronger antimicrobial effects.[8][9][10]
