IEM 1754 is an adamantane derivative. IEM 1754 causes use- and voltage-dependent block of open channels of recombinant AMPA receptors. This antagonism is dependent on receptor subunit composition, channels gated by recombinant, homomeric GluR1 and GluR3 receptors exhibites a higher sensitivity to block than those gated by receptors containing edited GluR2 subunits. IEM-1754 block of GluR2-containing AMPAR is enhanced by hyperpolarization in agreement with the classical single-exponential model. In contrast, the block of GluR2-lacking AMPAR is reduced by hyperpolarization.
