Ajmaline (Synonyms: Cardiorythmine; (+)-Ajmaline)

Cat. No.: HY-B1167 Purity: 99.84%
Handling Instructions

Ajmaline (Cardiorythmine) is a sodium channel blocking, class 1A anti-arrhythmic agent. Ajmaline blocks HERG currents with an IC50 of 1 μM in HEK cells and 42.3 μM in Xenopus oocytes. Ajmaline can be used for the research of the ventricular tachyarrhythmia.

Description

Ajmaline (Cardiorythmine) is a sodium channel blocking, class 1A anti-arrhythmic agent. Ajmaline blocks HERG currents with an IC50 of 1 μM in HEK cells and 42.3 μM in Xenopus oocytes. Ajmaline can be used for the research of the ventricular tachyarrhythmia[1][2].

In Vitro

Electrophysiological experiments are performed with human embryonic kidney (HEK) cells (whole-cell patch clamp) and Xenopus oocytes (double-electrode voltage clamp) expressing wild-type and mutant HERG channels. Ajmaline blocks HERG currents with an IC50 of 1.0μM in HEK cells and 42.3μM in Xenopus oocytes[2].
