CGP-39551 is a drug used in scientific research, it is investigated as an anti-convulsant.[2]
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.[3][4]
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.[5]
It has also been shown to be able to block convulsions caused by vestibular stimulation.[6]
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.[7]
