SYNTHESIS AND BIOLOGICAL EVALUATION OF NOVEL COUMARIN DERIVATIVES AS ANTIPLATELET AGENTS

摘要

In order to develop anti-thrombotic agents with higher potency, a series of novel coumarin derivatives (5a-m) were designed, synthesized and biologically evaluated. Compound 5e displayed the strongest activity in inhibiting the adenosine diphosphate (ADP)-induced platelet aggregation in vitro, with 2.3-fold more effectiveness than clinically used antiplatelet drug aspirin (ASP). Thus, Compound 5e could deserve further investigations as antiplatelet agents.
