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

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 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.

O, O-acetyldaurisoline(Adau) is a derivative of daurisoline (Dau). In cultured PC12 cells, Adau was found to inhibit K+, Bay K8644 and norepinephrine induced intracellular free calcium concentration increase. Adau was also shown to protect PC12 cells from hypoxia-reoxygenation injury with

To explore mechanisms of l-S.R-daurisoline (DS)-mediated protection of cultured hippocampal neurons from sodium glutamate (Glu) cytotoxicity. Cultured neurons obtained from rat hippocampus were used to examine the protective effect of DS against Glu neurotoxicity. Cell viability was estimated using trypan
