Two series of new PAR1 antagonists have been identified. The first incorporates a cinnamoylpiperidine motif and the second a cinnamoylpyridine pattern. The synthesis, biological activity and structure-activity relationship of these compounds are presented. In each series, one analog showed potent in vivo anti-thrombotic activity in a rat AV shunt model, with up to 53% inhibition at 1.25 mpk iv for compound 30. (C) 2010 Elsevier Ltd.
