Description

The pyrrolizidine alkaloid senecionine has been shown to produce an increase in cytosolic free Ca2+ concentration in isolated hepatocytes that correlated with an increase in cellular toxicity. Senecionine inhibits the sequestration of Ca2+ in extramitochondrial and mitochondrial compartments possibly by inactivating free sulfhydryl groups and oxidizing pyridine nucleotides respectively. Senecionine showed moderate antitrypanosomal activity with an IC50 value of 41.78 ug/ml.

Sample Use Guides

In Vivo Use Guide

Pharmacokinetic experiments of intravenous administration in the jugular-catheterized rat model: An aqueous solution contained senecionine was administered to rats intravenously at dose of 1.5 mg/kg. Pharmacokinetic experiments of oral administration in the jugular-catheterized rat model: An aqueous solution of senecionine was administered orally to rats by gavage at doses of 24, 12, and 6 mg/kg.

Route of Administration: Other

In Vitro Use Guide

Senecionine was cocultured for 2 hr with a NADPH-generating system and rat liver S9. Senecionine showed a dose-dependent inhibition of colony formation at 50, 100, and 300 uM and induction of megalocytosis at 500 uM.
