Competitive, selective, GluA2 (GluR2)-lacking AMPA receptor blocker
Competitive, selective, voltage-dependent open-channel Ca2+ permeable GluA2 (GluR2)-lacking AMPA receptor blocker (IC50 values are 2.6 and 1102 µM at GluA2-lacking and GluA2-containing AMPARs respectively).
IEM-1460 can be utilized as an indicator of the distribution of AMPA receptor subtypes among populations of brain cells.
IEM-1460 can also be used to selectively target GABAergic interneurons, as several subpopulations of these neurons express a significant proportion of GluA2-lacking Ca2+-permeable AMPARs.
Blocks synaptic excitation of fast-spiking interneurons and blocks NMDAR-mediated currents.
Also shows anticonvulsant properties.
