E-4031 shortens cardiac action potential duration.
By Anonymous on 05/16/2019
Assay Type: In Vitro
Species: Other
Cell Line/Tissue: Cardiomyocytes

A representative action potential of a guinea pig cardiomyocyte before and after perfusion with 500 nM E-4031 for 5 min and stimulated at a frequency of 1 Hz in a whole cell patch clamp model. E-4031 significantly shortened action potential duration of guinea pig ventricular cardiomyocytes.

Antiarrhythmic drug E-4031 was studied to identify drug effect: Overall great product.
By Anonymous on 10/22/2018
Assay Type: In Vitro
Species: Human

As an antiarrhythmic drug E-4031 was studied to identify drug effect. Concentration dependent Kv channel blocking and control of release were studied. The compound showed blocking activity which is not dependent on concentration administered and data was reproducible. Great product stability and dissolves nicely.
