Pleyotropic antiaggregant effects of an innovative antiarrhythmic of class III SS-68, an indole derivative

Abstract

A new indole derivative with the lab code-number SS-68 demonstrates a significant antiarrhythmic (anti-fibrillation) activity associated with the predominant influence on potassium and calcium conductivity of cardiomyocytes plasmalemmas. The preliminary data give evidence of SS-68 possessing an antiaggregant activity. The influence of SS-68 on the platelet formation stage of hemostasis was determined by assessment of the anti-platelet effect (measuring platelet aggregation with Born/ O’Brien method), the dynamics of intracellular concentration of calcium ions in platelets was studied with FURA-2/АМ fluorescent probe
