Atherosclerosis is a chronic inflammatory disease characterized by accumulation of lipid and fibrous components in arterial vessels, giving rise to atheromas. Development of Atheromatou plaques leads to arterial steatosis, triggering ischemic events. Atherotrombosis has a strong correlation with atherosclerosis, where rupture of atheromatous plaques cause release of vessel wall's pro-thrombotic components, activating platelet aggregation and thromosis. Due to the major role played by platelets on thrombus-embolic conditions, drugs that inhibit platelet aggregation demonstrate great relevance for atherothrombosis prevention, reducing patient mortality. Currently, there are a variety of drugs acting on several different targets, preventing platelet activation. However, these therapies demosntrate side effects such as thrombocytopenia, neutropenia, hemorrhage and low oral availability. Thus, the application of molecular modifications such as hybridization can produce novel, more efficient antiplatelet aggregation inhibitors. In this project we describe the synthesis and characterization of novel N-acilhydrazone compounds, acting through multiple mechanisms such as platelet calcium chelation and nitric oxide donation by furoxanic subunits. Furthermore, we demonstrate that such compounds exhibit biological activity in in vivo bleeding time, in vitro antiplatelet aggregation and in vivo antinociceptive assays. Therefore, novel N-acilhydrazone compounds demonstrate potential as antiplatelet drugs for atherothrombosis prevention.
