Therapeutic potential of excitatory amino acid antagonists: channel blockers and 2,3-benzodiazepines

Trends Pharmacol Sci. 1993 Sep;14(9):325-31. doi: 10.1016/0165-6147(93)90005-5.


NMDA and non-NMDA (AMPA/kainate) antagonists have potential in the treatment of a diverse group of neurological disorders associated with excessive activation of excitatory amino acid receptors. Here Michael Rogawski reviews recent progress in the development of therapeutically useful NMDA receptor channel blockers and a new class of selective AMPA/kainate receptor antagonists, the 2,3-benzodiazepines. Research on these novel noncompetitive excitatory amino acid antagonists has opened promising new avenues for the development of drugs to treat epilepsy, ischaemia, neurodegeneration and Parkinson's disease.
