Canadine (tetrahydroberberine,THB) is an isoquinoline alkaloid (5,8,13,13a-tetrahydro-9,10-dimethoxy-6H-benzo[g]-1,3-benzodioxolo[5,6-a]quinolizine) from Corydalis tuber, it has micromolar affinity for dopamine D(2) (pK(i) = 6.08) and 5-HT(1A) (pK(i) = 5.38) receptors but moderate to no affinity for other relevant serotonin receptors (i.e., 5-HT(1B), 5-HT(1D), 5-HT(3), and 5-HT(4). Canadine enhances gastrointestinal motor function. THB, with D(2) receptor antagonist and 5-HT(1A) receptor agonist properties, has significant potential as a therapeutic for treatment of functional dyspepsia. THB is a potent inhibitor of platelet aggregation in vitro and in vivo and is a promising antithrombotic drug.

Sample Use Guides

In Vivo Use Guide

Rats: Oral administration of Canadine not only resulted in the significantly accelerated gastric emptying of normal rats in a bell-shaped relationship, with a maximal efficacy at a dose of 30 ug/kg, but also restored the delayed gastric emptying caused by apomorphine, which might be mediated by an antidopaminergic effect.

Route of Administration: Oral

In Vitro Use Guide

Canadine (tetrahydroberberine,THB) (0.1-10 uM/L) shifted the dose-response curves to the right in a nonparallel fashion and decreased the maximal response (Emax) of both the fenoldopam(FODA, a selective DA1 agonist)-induced and the propyl-butyl-dopamine(PBDA, a selective DA2 agonist)-induced vasorelaxation, showing a non-competitive antagonistic action. The pD'2 values of THB for FODA in the renal, pulmonary and mesenteric arteries were 5.29, 5.37 and 5.46, respectively, while for PBDA in the mesenteric and femoral arteries were 5.53 and 5.48, respectively.
