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.

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

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.

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

Standard microelectrode technique was used to study the effect of daurisoline (DS) on delayed afterdepolarization (DAD) and triggered activity (TA) in guinea pig ventricular trabeculae. DS (50 mumol.L-1) abolished TA induced by ouabain or caffeine, inhibited isoprenaline-induced TA, decreased incidence

To explain the effect of daurisoline (DS) on delayed afterdepolarization (DAD). Ca(2+)-sensitive microelectrode technic was used to record intracellular Ca2+ activity (alpha Cai) and triggered activity (TA) arising from DAD in myocardium. Strophantin G 3 mumol.L-1 yielded an increase in
