AH-1058

AH-1058 is a newly synthesized antiarrhythmic agent that exhibits significant antiarrhythmic activity by delaying premature ventricular complexes and ventricular fibrillation in experimental arrhythmia models. AH-1058 effectively inhibits both ventricular tachycardia and ventricular fibrillation in the reperfusion-induced arrhythmia model in rats. AH-1058 demonstrates potent calcium channel-blocking effects, suppressing L-type Ca2+ currents in isolated cardiomyocytes.
