CGP-39551 is a drug used in scientific research, it is investigated as an anti-convulsant.[1]

Mechanism of action

[edit]

CGP-39551 and some related molecules are competitive antagonists of the N-methyl D-aspartate receptor, an excitatory receptor activated by glutamate.[2][3]

Potential

[edit]

As other glutamate antagonists, CGP-39551 possesses anti-convulsant properties. It is able to suppress seizures caused by electroshock, with a duration of action superior to 24 hours.[4]

It has also been shown to be able to block convulsions caused by vestibular stimulation.[5]

Additionally, CGP-39551 appears to be better than some other NMDA blockers in terms of side effects, since the dose required for its anti-convulsant action does not have significant impact on memory and learning, unlike certain drugs with a similar mechanism of action such as Dizocilpine.[6]
