1、分子量309.32 溶解性（25C） DMSO 分子式C H NOWater CAS号338747-41-4Ethanol 储存条件3年 -20C 粉末状 生物活性 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) recepto
2、rs 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 stat
3、es, such as Alzheimers. M1 agonists are being studied as potential therapeutic agents to treat Alzheimers disease and the cognitive and negative symptoms of schizophrenia. BQCA has been shown to improve performance in cognition tasks and increase cerebral blood flow. 不同实验动物依据体表面积的等效剂量转换表（数据来源于FDA指南） 小鼠大鼠兔豚鼠仓鼠狗 重量 (kg)0.020.151.80.40.0810 体表面积 (m )0.0070.0250.150.050.020.5 K 系数36128520 动物 A (mg/kg) = 动物 B (mg/kg) 动物 B的K 系数 动物 A的K 系数 例如，依据体表面积折算法，将白藜芦醇用于小鼠的剂量22.4 mg/kg 换算成大鼠的剂量，需要将22.4 mg/kg 乘以小鼠的K 系数（3），再除以大鼠的K 系数（6）， 得到白藜芦醇用于大鼠的等效剂量为11.2 mg/kg。 BQCA 目录号M8368 化学数据 18154 2 m m m mm
