摘要:
Investigations on P-2-P-3-heterocyclic dipeptide surrogates directed towards identification of an orally bioavailable thrombin inhibitor led us to pursue novel classes of achiral, non-covalent P-1-arginine derivatives. The design. synthesis. and biological activity of inhibitors NC1-NC30 that feature three classes of monocyclic P-1-arginine surrogates will be disclosed: (1) (hetero)aromatic amidines, amines and hydrox amidines, (2) 2-aminopyrazines. and (3) 2-aminopyrimidines and 2-aminotetrahydropyrimidines.
