      A. Representative time course of NR1/NR2A currents, elicited by transient stimulations with 20 µM glutamate + 20 µM glycine every 50 sec, while membrane potential was held at -60 mV, and significantly inhibited by 10 μM IEM-1921 (#I-180).
      B. Superimposed current traces from the recording shown in A, following application of control and 10 μM IEM-1921. Transient stimulation is indicated by an arrow.

    Scientific background

    N-methyl-D-aspartate (NMDA) receptors, a family of L-glutamate receptors, play an important role in the central nervous system. Activation of NMDARs leads to cytosolic free intracellular calcium ([Ca2+]i) increase and for synaptic plasticity1.

    Abnormal activity of NMDA receptors is associated different neurodegenerative disorders such as Alzheimer’s, Huntington’s, Parkinson’s disease and the etiology of epilepsy1.

    IEM-1921, also known as 1-phenylcyclohexylamine, is a selective blocker of NMDA receptors. In chronic experiments on Wistar and Krushinskii–Molodkina rats it was found that IEM-1921 (5mg/kg) acts as anticonvulsant. IEM-1921 decreased the duration of convulsions by 82% and prevent neural abnormalities in the brain2-3.
