Antiarrhythmic

Hirsuteine
Catalog No: CFN90615

Hirsuteine exhibits potent neuroprotective effects against glutamate-induced HT22 cell death. Hirsuteine non-competitively antagonizes nicotine-evoked dopamine release by blocking ion permeation through nicotinic receptor channel complexes.

Hirsutine
Catalog No: CFN90617

Hirsutine has anticancer, cardioprotective, anti‑hypertensive and anti-arrhythmic activities, it also has vasodilatation activity, the mechanism is related to blockade of Ca2+ influx through L-type Ca2+ channels and inhibition of intracellular Ca2+ release may have no relationship with K+ channels. Hirsutine reduces the production of various neurotoxic factors in activated microglial cells and possesses neuroprotective activity in a model of inflammation-induced neurotoxicity.

Ajmaline
Catalog No: CFN93513

Ajmaline is a class Ia anti-arrhythmic compound that is widely used for the diagnosis of Brugada syndrome and the acute treatment of atrial or ventricular tachycardia. Ajmaline inhibits cardiac Kv1.5 and Kv4.3 channels at therapeutic concentrations.

Dimethyl lithospermate B
Catalog No: CFN90690

Dimethyl lithospermate B is a highly potent natural antioxidant and antidiabetic polyphenol with unknown mode of action.Dimethyl lithospermate B slows inactivation of INa, leading to increased inward current during the early phases of the action potential (AP), might be an excellent candidate for a Na(+) channel agonist; it is effective in eliminating the arrhythmogenic substrate responsible for the Brugada syndrome and that it deserves further study as a pharmacological adjunct to implanted cardioverter/defibrillator usage.

Astringin
Catalog No: CFN92486

Astringinin is a potent antiarrhythmic agent with cardioprotective activity in ischemic and ischemic-reperfused rat heart, the beneficial effects of astringinin in the ischemic and ischemic-reperfused hearts may be correlated with its antioxidant activity and upregulation of NO production. Astringinin can significantly attenuate proinflammatory responses and hepatic injury after trauma-hemorrhage, the salutary effects of astringinin administration on attenuation of hepatic injury following trauma-hemorrhage are likely due to reduction of pro-inflammatory mediator levels.
