Quinidine gluconic acid
Based on 25 publication(s) in Google Scholar
Quinidine gluconic acid is an orally effective antiarrhythmic agent. Quinidine gluconic acid blocks the fast inward sodium current in a use-dependent manner, blocks IKr in a reverse use-dependent manner, and blocks the ultra-rapid delayed rectifier potassium current with an EC50 of 6.2 μM, while also inhibiting CYP2D6 and P-gp. Quinidine gluconic acid induces PARP cleavage, Caspase-3 activation, and increases the proportion of sub-G1 phase apoptotic (Apoptotic) cells. Quinidine gluconic acid can be used in research on ischemia/reperfusion-induced cardiac injury, drug-resistant leukemia, convulsions, and uterine sarcoma.
