认证机构产品是BQCA is a potent M1 muscarinic acetylcholine receptor (mAChR) positive allosteric modulator with selectivity for M1 over M2-M5. The effective range for potentiation of M1 in cells by BQCA is 0.1 to 100 μM with an inflection point value of 845 nM when 3 nM acetylcholine is used. BQCA displays no potentiation, agonism, or antagonism at other mAChRs at concentrations up to 100 μM.
