Abstract

Aim. To study the biochemical effect on hemostasis of a new cyclohexilammonium salt of 2-[1-ethyl-3-methyl-7(dioxotiethanyl-3)xantinyl-8-thio]acetic acid in vitro. Methods. Thromboelastography was performed using the citrate blood samples of healthy male donors. Global hemostatic effect, fibrinogen and platelet function, fibrinolysis and clot strength, and stability were analyzed at thromboelastography. The impact of firstly synthesized xantine derivative and pentoxifylline on the functional activity of platelets in vitro was studied using a laser analyzer of platelet aggregation. Adenosine diphosphate, collagen, epinephrine and ristocetin induced clotting were registered. General clotting characteristics, maximal aggregation values, maximal aggregation speed, mean platelet aggregate size, activity of platelet-derived factor 3, level of platelet-derived factor 4 were measured. Release of platelet-derived factors 3 and 4 at platelet aggregation were assessed after adenosinediphosphate-induced aggregation and centrifugation. Results. Cyclohexylammonium salt of 2-[1-ethyl-3-methyl-7-(dioxotiethanyl-3)xantinyl-8-thio]acetic acid in vitro showed antiaggregatory activity that exceeds such of pentoxifylline. It has been revealed that the second platelet aggregation wave, that is induced by small dose of adenosinediphosphate, is absent in the presence of the new cyclohexylammonium salt, lag-period in collagen-induced platelet aggregation elongates, and availability and release of platelet-derived factors 3 and 4 decreases. Conclusion. The research findings show potentially high antiaggregatory activity of 2-[1-ethyl-3-methyl-7-(dioxotiethanyl-3)xantinyl-8-thio]acetic acid cyclohexylammonium salt as an inhibitor of platelet release reaction.
