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.

To establish the determination method of dauricine (Dau) concentration in rats' blood and other biological samples, a reverse-phase HPLC method was adopted. Under the given condition, dauricine could be well separated. The retention time (tR) of Dau and its internal

1. The extracellular glutamate content and Ca2+ level in vivo in rat hippocampus were measured by brain microdialysis following administration of two depolarizing agents (veratridine, KCl) and quinolinic acid (Quin). 2. The two depolarizing agents increased the extracellular glutamate level

We investigated the neuroprotective efficacy of the P-type Ca2+ channel antagonist daurisoline against electroshock-induced convulsions in rats and mice, hypoxic/hypoglycemic-induced damage in rat hippocampal slices and brain damage induced by occlusion of the middle cerebral artery (MCA) in rats. Daurisoline

Cytosolic free Ca2+ ([Ca2+]i) was measured in dissociated cerebral cells isolated from fetal rats with the fluorescent indicater fura-2. Increase in [Ca2+]i occurred rapidly following exposure of the cells to 50 mmol/L KCl, 10(-7) mol/L Bay K 8644 or 200

1. The effects of (-)-daurisoline on 45Ca2+ uptake and [3H]-gamma-aminobutyric acid ([3H]-GABA) release from synaptosomes of rat cerebral cortex and on contractile activity of rat aorta were examined. 2. Application of (-)-daurisoline (1-100 microM) produced concentration-related inhibition of high K(+)-stimulated
