What is IDRA-21 Powder?
IDRA-21 Powder (CAS 22503-72-6, ≥99% HPLC) is a high-purity, orally active AMPA receptor positive allosteric modulator (ampakine) belonging to the benzothiadiazine class. It enhances glutamatergic synaptic transmission and plasticity, effectively boosting learning, memory and cognitive flexibility while exerting neuroprotective effects. Widely used in cognitive neuroscience, neuropharmacology and psychiatric disorder research, it is an essential tool compound for exploring AMPA receptor function and developing novel nootropic drugs.
Core Features
High-purity research-grade powder with excellent batch consistency and low residual impurities
Highly potent, orally active AMPA modulator with no significant neurotoxicity
Enhances cognitive functions at low doses without receptor desensitization
Stable chemical structure under standard storage conditions; easy to handle in labs
Widely cited in top journals (e.g., Nature, Cell) for high reliability

IDRA-21 Powder Benefits and Function
Its biological effects stem from selective interaction with AMPA receptors-ionotropic glutamate receptors central to fast excitatory synaptic transmission and memory formation:
Inhibits Receptor Desensitization: Binds to an allosteric site on AMPA receptors (e.g., GluA1/2 subtypes) to slow desensitization during prolonged glutamate exposure. This prolongs receptor activation, enhancing Na⁺/Ca²⁺ ion influx into neurons.
Strengthens Synaptic Plasticity: By sustaining AMPA receptor activity, it promotes long-term potentiation (LTP)-the molecular basis of learning and memory-especially in the hippocampus (a brain region critical for memory consolidation).
Superior BBB Penetration: More effective at crossing the blood-brain barrier than related compounds (e.g., cyclothiazide), ensuring efficient access to central nervous system (CNS) targets.
Cognitive Enhancement (Primary Activity)
Memory & Learning Improvement: In preclinical models (e.g., patas monkeys, rodents), it reverses pharmacologically induced cognitive impairments and boosts spatial memory/associative learning . At 70μM, it doubles glutamate-induced charge transfer in GluA1/2-expressing cells, indicating enhanced synaptic signaling .
Mood & Focus Support: Preliminary data suggests it improves mood and sensory perception by strengthening glutamatergic synapses in brain regions linked to attention.
