Biochem/physiol Actions

Daurisoline alkaloid isolated from the rhizomes of Menispermum dauricum that exhibit varies pharmacological activities including antiplatelet aggregation, anti-inflammatory, neuron-protective properties, and antiarrhythmic effect. It appears that antiarrhythmic effect of daurisoline is maintained through blockade of hERG channels.
Daurisoline is antiarrythmic, anti-inflammatory, neuron-protective; and blocks hERG channels.

Acta pharmacologica Sinica, 23(5), 423-429 (2002-04-30)
To gain further insights into the mechanism of the ATP-dependent interaction of P-glycoprotein (P-gp) with various multidrug resistance (MDR) reversal agents. Bovine brain capillary endothelial cells (BCEC) were isolated from cerebral gray matter using modifications of the mechanical homogenization technique.

The alkaloid and medicinal herb constituent, R,R-(-)-daurisoline, was originally reported to be a N-type Ca2+ channel blocker, but newer evidence indicates that it is a blocker of P-type Ca2+ channels. To clarify its specificity with respect to N- and P-channels

To establish an HPLC method for the determination of daurisoline (DS) in rabbit plasma and investigate its pharmacokinetic characteristics after intravenous administration. Dauricine was used as internal standard. The plasma samples were deproteinated with acetonitrile and extracted with two-step dichloromethane.
Z Y Hu et al.
Cellular signalling, 2(4), 353-357 (1990-01-01)
Daurisoline alkaloid derivatives were found to be potent calmodulin (CaM) antagonists. The ability of daurisoline derivatives to attenuate the stimulatory effect on calmodulin activated cyclic nucleotides phosphodiesterase (CaM-PDE) was studied. These compounds did not inhibit the basal activity of this
