      • CGS 19755 (Selfotel) is a highly selective, potent and competitive N-methyl-D-aspartate (NMDA) receptor antagonist. The compound binds directly and competitively to the postsynaptic NMDA receptor, competing with glutamate. CGS 19755 is a racemic mixture and a rigid analogue of 2-amino-5-phosphonopenranoic acid (AP5). The compound demonstrates anticonvulsant, anxiolytic and anti-ischemic effects. For appropriate clinical application, CGS 19755 better be administrated intravenous since orally administration is not very active1,2. Several studies have found that CGS 19755 has the ability to limit neuronal damage in animal stroke models.

        NMDA receptors play an important role in a variety of cellular processes and brain functions such as, synaptic plasticity, addiction and stroke. They mediate physiological functions such as learning and memory formation. These receptors play a role in glutamate excitotoxicity and are involved in many neurodegenerative conditions3. NMDA antagonists are effective in limiting ischemic damage to the brain and spinal cord. As shown in several studies, this compound has the ability to prevent ischaemia-induced hippocampal cell damage in gerbils.

        This anti-ischemic properties makes this compound to be a very attractive application for clinical investigation4,5.
