IDRA-21 is a positive allosteric modulator of the AMPA receptor and a benzothiadiazine derivative. It is a chiral molecule, with (+)-IDRA-21 being the active form.[1]
IDRA-21 shows nootropic effects in animal studies, significantly improving learning and memory. It is around 10–30 times more potent than aniracetam in reversing cognitive deficits induced by alprazolam or scopolamine,[2][3] and produces sustained effects lasting for up to 48 hours after a single dose.[4] The mechanism for this action is thought to be through promoting the induction of long-term potentiation between synapses in the brain.[5]
IDRA-21 may not produce neurotoxicity under normal conditions,[6] although it may worsen neuronal damage following global ischemia after stroke or seizures.[7]
In comparison to the ampakines or benzoylpiperidine-derived AMPA receptor potentiators, IDRA-21 was more potent than CX-516, but less potent than CX-546.[8] Newer benzothiadiazide derivatives with greatly increased potency compared to IDRA-21 have been developed,[9][10] but these have not been researched to the same extent, with the benzoylpiperidine and benzoylpyrrolidine CX-series of drugs being favoured for clinical development, most likely due to more favourable toxicity profiles at high doses.[11]
