Electrochemical Synthesis of Novel 1,3-Indandione Derivatives and Evaluation of Their Antiplatelet Aggregation Activities

Electrochemical oxidation of some selected catechol derivatives, using cyclic voltammetry, in the presence of different 2-aryl-1,3-indandiones as nucleophiles, resulted in electrochemical synthesis of new 1,3- indandione derivatives in an undivided cell in good yield and purity. a michael addition mechanism was proposed for the formation of the analogs based on the reaction conditions which were provided in electrochemical cell. the in-vitro antiplatelet and anticoagulant activity of these compounds was evaluated, using arachidonic acid (aa) and adenosine diphosphate (adp) as the platelet aggregation inducers. the results show that the incorporation of catechol ring in 1,3-indandione nucleus leads to the emergence of antiplatelet aggregation activity in these compounds. the compounds may exert their antiaggregation activity by interfering with the arachidonic acid pathway.
