Preview

The ability of d-α-aminoadipate (DAA) and a range of related substances to act as amino acid antagonists has been found to parallel the ability of these substances to displace binding of tritiated ligands from the recognition site of the NMDA receptor. Important exceptions include Mg2+ and HA-966, which do not displace [3H] d-2-amino-5-phosphonovalerate (d-AP5), a competitive-type NMDA receptor antagonist, from rat brain binding sites. Several other groups of compounds joined this ‘non-competitive’ list in the 1980s and 1990s. This chapter concentrates on chemicals acting at sites other than that for NMDA recognition but which nevertheless influence the functions of the NMDA receptor channel complex.
