Acyl guanidine, thioguanidine and amidine compounds are provided which have the structure
wherein Z is a substructure which when linked to
forms a prodrug of compounds with pharmaceutically active properties. In preferred embodiments, Z is a thrombin inhibitor substructure containing residues binding at the distal and proximal sites with the proviso that Z does not contain boron or a boron-containing moiety.
Ax and A'x may be the same or different and are independently selected from Acyl, H or alkyl, at least one of Ax and A'x being Acyl; and
including all stereoisomers thereof, and pharmaceutically acceptable salts thereof.
