The antiarrhythmic activity of amino acid-containing derivatives of 1,4-naphthoquinone

In recent times, the issue of cardiac arrhythmia disturbances has garnered increasing attention from researchers. Pharmacotherapy continues to be the primary method for treating rhythm disturbances; however, its effectiveness is often limited due to the common side effects associated with many antiarrhythmic drugs, among which negative inotropic action plays a significant role. One direction in the development of antiarrhythmic agents involves the targeted search for new drugs among agents with metabolic effects. The aim of this study was to investigate the antiarrhythmic activity using models of occlusion and reperfusion arrhythmias in cats, aconitine arrhythmias in rats, and calcium chloride ventricular fibrillation in rats of five original amino acid-containing derivatives of 1,4-naphthoquinone, synthesized at the Lviv Polytechnic Institute under the guidance of Ph.D. A.P. Kartoflitska. The conducted research indicated that the studied compounds exhibit antiarrhythmic effects. The enhancement of the antiarrhythmic activity occurred primarily in those arrhythmia models where metabolic disorders play a significant role in the pathogenesis.
