IDRA-21 is a second-generation benzothiadiazide ampakine \u2014 a positive allosteric modulator of the AMPA subtype of ionotropic glutamate receptors \u2014 first characterized in the early 1990s as part of the medicinal-chemistry program that produced the entire ampakine family at UC Irvine \u03ba\u03b1\u03b9 later at Cortex Pharmaceuticals [1]. The molecule slows AMPA-receptor desensitization \u03ba\u03b1\u03b9 deactivation, increasing the integrated excitatory postsynaptic current produced by a given glutamate release event without itself activating the receptor [1,2]. In behavioural studies, IDRA-21 produces dose-dependent enhancement of acquisition, consolidation \u03ba\u03b1\u03b9 retrieval across passive-avoidance, delayed-matching-to-sample \u03ba\u03b1\u03b9 spatial-memory paradigms in rodents \u03ba\u03b1\u03b9 non-human primates, with documented increases in hippocampal LTP magnitude \u03ba\u03b1\u03b9 BDNF release [1,2,3]. While newer, more potent ampakines (CX-717, TAK-653) have since superseded IDRA-21 in clinical development, IDRA-21 retains a unique position as the most extensively published benchmark molecule in AMPA-PAM cognitive-enhancement research \u2014 the canonical reference compound for ampakine pharmacology \u03ba\u03b1\u03b9 the st\u03ba\u03b1\u03b9ard against which newer molecules are characterized.<\/p>\n
