N-Methyl-D-aspartate (NMDA) receptors mediate excitatory synaptic transmission in the central nervous system and play important roles in synaptic development and plasticity, but also mediate glutamate neurotoxicity. Recently, 2-naphthoic acid (NPA) and its derivatives have been identified as allosteric, noncompetitive NMDA

Urine was collected from four female rats for 3 days after two subcutaneous injections with 0.3 mg of 2-methyl[8-14C]naphthalene per kg. Of the 14C injected, 55% was found in the urine. The urine was solvent-fractionated into a toluene fraction (4.9%

Over-activation of N-methyl-d-aspartate (NMDA) receptors is critically involved in many neurological conditions, thus there has been considerable interest in developing NMDA receptor antagonists. We have recently identified a series of naphthoic and phenanthroic acid compounds that allosterically modulate NMDA receptors
