Descripción

General description

Strychnine is a colorless, odourless and bitter tasting powder. It is absorbed in skin, gastrointestinaland respiratory tract. Strychnine generates oxides of nitrogen and carbon on decomposition.

Strychnine is a glycine receptor antagonist not associated with the N-methyl-D-aspartate (NMDA) receptor. It is an alkaloid extracted from Strychnos nux vomica seeds.

Application

Strychnine has been used as a glycine receptors antagonist in hippocampal CA1 pyramidal and rostral ventromedial medulla (RVM) neurons. It has also been used as type C glycine receptor antagonist in direction selective (DS) retinal cells.

Strychnine has been used in antagonist profiling to characterize a novel nicotinic receptor in Aplysia neuroendocrine cells.

Biochem/physiol Actions

At low doses, strychnine is used for circulatory problems, gastrointestinal disorders and eye diseases.

Strychnine is used as a rodenticide and a glycine receptor antagonist, which inhibits Renshaw cell-motor neuron synapse. It binds to the α subunit N-terminal region of the glycine receptor. The effect of strychnine is neutralized in the presence of glycine receptor agonist ivermectin. Strychnine also inhibits leukocyte motility.

Produce convulsiones; antagonista en los receptores de glicina no competitivo con el receptor NMDA.
