Ajmaline is an alkaloid that has been found in R. serpentina and has ion channel inhibitory and antiarrhythmic activities.1,2,3,4,5 It inhibits the human-ether-a-go-go (hERG) potassium channel, also known as Kv11.1, and the voltage-gated potassium channel subtypes Kv1.5 and Kv4.3 with IC50 values of 42.3, 293, and 186 ?M, respectively, in Xenopus oocytes expressing the channels.2,3 Ajmaline (1 ?g/ml) increases the action potential duration in isolated dog atrium and ventricle.4 It increases the functional refractory duration in the atrium, ventricle, and atrioventricular conduction system in anesthetized dogs when administered intravenously at a dose of 1 mg/kg.4 Ajmaline (2 mg/kg, i.v.) reduces the number of premature ventricular complexes and decreases the duration of ventricular tachycardia and ventricular fibrillation in coronary artery-ligated anesthetized rats.5

计算结果:
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。
3. 以上所有助溶剂都可在 GlpBio 网站选购。
