Biochem/physiol Actions

BQCA is a potent muscarinic M1 receptor positive allosteric modulator with selectivity for M1 over M2-M5. It potentiates M1 activity in in vitro and in vivo assays and is orally bioavailable. Muscarinic 1 (M1) receptors are expressed in brain regions responsible for attention and memory, including hippocampus, cortex, and striatum. BQCA binds allosterically to M1 to enhance the binding and efficacy of ACh at the receptor. M1 activation is a proposed mechanism for increasing information processing in disease states, such as Alzheimer′s. M1 agonists are being studied as potential therapeutic agents to treat Alzheimer′s disease and the cognitive and negative symptoms of schizophrenia. BQCA has been shown to improve performance in cognition tasks and increase cerebral blood flow.
