Ricinine is an alkaloid originally isolated from the Ricinus communis, or castor-oil plant. Ricinine can be found in all parts of the plant and it is a quite strong insecticide. The castor seeds contain approximately 0.2% of the alkaloid. Ricinine or 3-cyano-4-methoxy-N-methyl-2-pyridone (CAS 524-40-3) belongs to the group of piperidine alkaloids. Ricinine is a useful scaffold for the synthesis of new antimicrobial and antiquorum-sensing derivatives in spite of its poor contribution to the antimicrobial activity of the plant extracts. Ricinine activated the Wnt signaling pathway by inhibiting casein kinase 1α. Ricinine-elicited seizures as a novel chemical model of convulsive seizure.

Sample Use Guides

In Vivo Use Guide

mice: 60 mg/kg body weight, orally, reduced the extensor tonus phase of convulsion by MES-induced seizures in albino mice. However, ricinine induces seizures when administered to mice at doses higher than 20 mg/kg. In experimental mouse models ricinine causes hyperactivity, seizure and subsequent death due to respiratory arrest. LD50 values for ricinine were 340 mg/kg for intraperitoneal and 3 g/kg for oral incorporation.

Route of Administration: Oral

In Vitro Use Guide

higher doses of ricinine (4 mM) caused a small impairment of mitochondrial respiration.
