Routine screening of compounds for inhibition of ADP-inducedplateletaggregation in vitro revealed that 1,1'-hexamethylenebis[3-cyclohexyl-3-[(cyclohexylimino) (4-morpholinyl) methyl]urea] (1) was active and represented the first example of a bis(acylguanidine) with possible antithrombotic activity. In order to develop a structure-activity relationship for this class of compounds, we synthesized a
