IC50: 25 nM for AMPA receptor-mediated currents in rat cortical neurons CP-465022 is an AMPA antagonist. The inhibition of alpha-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid (AMPA) receptor has been hypothesized to lead to neuroprotective efficacy after cerebral ischemia on the basis of the activity in ischemia models of a variety of compounds with varying selectivity for AMPA over other glutamate receptor subtypes. In vitro: CP-465022 inhibited AMPA receptor-mediated currents in rat cortical neurons and such inhibition was found to be noncompetitive with agonist concentration. CP-465022 was selective for AMPA over kainate and N-methyl-D-aspartate receptors. However, CP-465022 was found to be equipotent for AMPA receptors composed of different AMPA receptor subunit combinations, which indicated that CP-465022 is equivalently potent for inhibition of AMPA receptor-mediated responses in different types of neurons expressing different AMPA receptor subunits . In vivo: Animal study showed that CP-465022 could potently and efficaciously inhibit AMPA receptor-mediated hippocampal synaptic transmission and the induction of seizures. However, at comparable doses, CP-465022 failed to prevent CA1 neuron loss after brief global ischemia or to reduce infarct volume after temporary middle cerebral artery occlusion . Clinical trial: So far, no clinical study has been conducted.
