摘要

We studied parameters of specific binding for various ligands of imidazole receptors and alpha2-adrenoceptors on human platelets. Pharmacological activity of compounds was evaluated by their effects on platelet aggregation induced by ADP in low concentrations (0.125-1.5 microM). In contrast to alpha2-adrenoceptor agonist norepinephrine inducing reversible aggregation of cells, selective stimulation of imidazole receptors with moxonidine produced a disaggregation effect. The data suggest that human platelets can be used as an experimental test system for screening and study of molecular mechanisms underlying the influence of new compounds.
