Flecainide acetate is a class Ic antiarrhythmic agent, it is used to treat a variety of cardiac arrhythmias including paroxysmal atrial fibrillation, paroxysmal supraventricular tachycardia, and ventricular tachycardia. It works by regulating the flow of

Xamoterol hemifumarate is a potent and selective β1-adrenoceptor agonist.Xamoterol hemifumarate is a potential compound for the study of the relationship between cardiac arrhythmias and β1-adrenergic stimulation with IKr.

BN 50739 is an antagonist of platelet-activating factor (PAF). BN 50739 suppresses certain cardiac arrhythmias. PAF is released from ischaemic myocardium and may contribute to initiation of ischaemia-induced ventricular fibrillation (VF)

1. Crebanine iv 5mg kg can eonvert BaCl_2-induced arrhythmia into sinus rhythm in rats, and can significantly increase the tolerant dose of aconitine to produce ventrieular fibrillation(VF) and cardiac arrest (CA) in rata. 2. Crebanine can also decrease t

Nafazatrom is a pyrazolinone derivative and lipoxygenase inhibitor that increases endogenous prostacyclin (PGI2) and has experimental anticancer activity. Nafazatrom is also an antithrombotic drug that increases prostacyclin levels and reduces the inciden

Ru360, an oxygen-bridged dinuclear ruthenium amine complex, is a selective mitochondrial calcium uptake inhibitor. Ru360 potently inhibits Ca2+ uptake into mitochondria with an IC50 of 0.184 nM. Ru360 binds to mitochondria with high affinity (Kd of 0.34 nM). Ru360 has antiarrhythmic and cardioprotective effects[1][2]. Ru360 permeates slowly into the cell, and specifically inhibits mitochondrial calcium uptake in intact cardiomyocytes and in isolated heart. 1 μm Ru360 is taken up by myocardial cells and accumulated in the cytosol in a biphasic manner[1]. During pelleting hypoxia, Ru360 (10 µM) significantly improves cell viability in wild type cardiomyocytes[3]. Ru360 (15-50 nmol/kg) treatment abolishes the incidence of arrhythmias and haemodynamic dysfunction elicited by reperfusion in a whole rat model. Ru360 administration partially inhibits calcium uptake, preventing mitochondria from depolarization by the opening of the mitochondrial permeability transition pore (mPTP)[1]. [1].
