Description of:BQCA(cas:338747-41-4)
BQCA is a potent muscarinic M1 receptor positive allosteric modulator with selectivity for M1 over M2-M5. Stimulation of the cortical muscarinic M1 receptor (CHRM1) is proposed as a treatment for schizophrenia, a hypothesis testable using CHRM1 allosteric modulators. 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
BQCA reduces the concentration of ACh required to activate M1 up to 129-fold with an inflection point value of 845 nM. No potentiation, agonism, or antagonism activity on other mAChRs is observed up to 100 μM[1]. BQCA increases M1 receptor affinity for acetylcholine. The activation of the M1 receptor by BQCA induces a robust inward current and increases spontaneous excitatory postsynaptic currents in medial prefrontal cortex (mPFC) pyramidal cells
