Effect of modulators of the polyamine site on the development of seizures induced by systemic and intracerebral administration of N-methyl-D-aspartate in albino mice

Abstract: Systemic intraperitoneal administration of polyamine agonist IEM-1460 containing the Me3N(+) group with a stable positive charge preventing permeation of this substance through the blood-brain barrier and polyamine antagonist arcaine had no effect on the development of seizures caused by intracerebral injection of N-methyl-D-aspartate in mice. Intraperitoneal injection of IEM-40 potentiated, while arcaine decreased the severity of seizures induced by intraperitoneal treatment with N-methyl-D-aspartate. This ef… Show more

“…These data indicate that the decrease in BBB permeability to the polar compound induced by a polyamine antagonist arcaine [1] was not followed by significant reduction in BBB permeability to lipophilic nicotine. As differentiated from polar compound NMDA, nicotine easily crosses BBB.…”

“…By contrast, administration of polyamine antagonist arcaine prevents seizures induced by intraperitoneal injection of NMDA. The observed effects are associated with opposite changes in BBB permeability to NMDA, which results from modulation of the NMDA receptor polyamine site in BBB cells [1].…”
