Peripheral and central routes of administration of quaternary ammonium compound IEM-1460 are equally potent in reducing the severity of nicotine-induced seizures in mice.
Peripheral administration of nicotinic receptor antagonists with a quaternary ammonium group (hexamethonium and chlorisondamine) did not prevent the development of seizures induced by systemic treatment with nicotine in the toxic dose. The Me3N+ group with stable positive charge inhibits transport of these compounds into the brain through the blood-brain barrier. Intracerebral and peripheral (intraperitoneal) administration of compound IEM-1460 with the Me3N+ group was equally potent in reducing the severity of nicotine-induced seizures in mice. This phenomenon is related to the fact that IEM-1460 acts as a nicotinic receptor antagonist and polyamine agonist, which increases blood-brain barrier permeability for polar compounds. These features contribute to IEM-1460 transport into the brain. High anticonvulsant activity of IEM-1460 on the model of nicotine-induced seizures is associated with combined blockade of nicotinic receptors (alpha3beta4 receptors) and glutamate receptors (GluR1 AMPA receptors).
