Benzonatate
(Synonyms: 苯佐那酯,Benzononatine) 目录号 : GC42919A voltage-gated sodium channel blocker
Cas No.:104-31-4
Sample solution is provided at 25 µL, 10mM.
Benzonatate is a reversible voltage-gated sodium channel blocker.[1] It blocks Nav1.7 currents in a concentration- and voltage-dependent manner (IC50s = 5.9 and 1.4 μM at holding potentials of -100 and -70 mV, respectively) and inhibits action potential firing in catecholamine A differentiated (CAD) cells. Benzonatate also blocks 80% of Nav1.3 currents in N1E-115 cells when used at a concentration of 100 μM. In vivo, benzonatate (0.85 mg/min) reduces the frequency, but has no effect on the amplitude, of the cough reflex in anesthetized dogs.[2] Formulations containing benzonatate have been used as antitussive agents for the treatment of coughs.

工作液浓度: mg/ml;
DMSO母液配制方法: mg 药物溶于 μL DMSO溶液(母液浓度 mg/mL,
体内配方配制方法:取 μL DMSO母液,加入 μL PEG300,混匀澄清后加入μL Tween 80,混匀澄清后加入 μL saline,混匀澄清。
1. 首先保证母液是澄清的;
2.
一定要按照顺序依次将溶剂加入,进行下一步操作之前必须保证上一步操作得到的是澄清的溶液,可采用涡旋、超声或水浴加热等物理方法助溶。
