title: [Effect of dopamineamides of polyunsaturated fatty acids on blood coagulation system and cerebral circulation].
abstract: A series of original dopaminamides of polyunsaturated fatty acids were synthesized and characterized with respect to antiaggregant and cerebrovascular stimulant properties. It was established that dopaminamides of linolic, dimethyllinolic, docosapentaenoic, docosahexaenoic (DHEA) and stearidonic (C18:4 and C18:3) acids decrease ADP and arachidonic acid (AA) induced human thrombocyte aggregation in vitro. The most pronounced antiaggregant effect was observed for DHEA dopaminamide: in a dose of 10 mg/kg, this agent produced a significant decrease in the AA induced thrombocyte aggregation. DHEA per se in the same dose increases the activated partial thromboplastin time (APTT), while not affecting the prothrombin time. The synthesized dopaminamides of arachidonic, eicosapentaenoic, and docosahexaenoic acids stimulate local circulation in the cerebral cortex. The most pronounced cerebrovascular effect was also produced by DHEA dopaminamide.
