生物活性:
Aprindine hydrochloride is a class I-b anti-arrhythmic agent and a hERG channel blocker with an IC50 of 0.23 μM. Aprindine hydrochloride has inhibitory effects on Na+/Ca2+ exchanger currents, which is partly responsible for their antiarrhythmic and cardioprotective effects. Aprindine hydrochloride is widely used for trial and ventricular tachyarrhythmias research research.

体外研究:
Aprindine (3?μM) inhibits the delayed rectifier K+?current (IK) with little influence on the inward rectifier K+?current (IK1) or the Ca2+?current.The muscarinic acetylcholine receptor-operated K+?current (IK.ACh) was activated by the extracellular application of carbachol (1?μM) or by the intracellular loading of GTPγS. Aprindine inhibits the carbachol- and GTPγS-induced IK.ACh with the IC50?values of 0.4?μM and 2.5?μM, respectively.
