Synthesis of novel 3-carboxamide-benzocoumarin derivatives as orally active antithrombotic agents

In an effort to develop potent antithrombotic agents, a series of novel 3-carboxamide-benzocoumarin derivatives were synthesized and screened for their in vivo antithrombotic activity. Among 20 compounds tested, the compound 12b showed the most promising antithrombotic activity which was comparable with clinically used aspirin or warfarin, but, at variance with these standard drugs, 12b did not exhibit the increased bleeding time, suggesting its potential as a novel antithrombotic agent.
