BQCA

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.
