Actions biochimiques/physiologiques

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.

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 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
