In the course of our research for the low-molecular weight RGD peptide mimics, we have found that a rigid 2-acylimino-3H-thiazoline structure is suitable for the peptide backbone mimics. Introduction of amidinophenyl and p-alanine moiety as arginine and aspartic acid side-chain surrogates to this backbone mimic resulted in a highly potent fibrinogen receptor antagonist 2-(4-amidinobenzoylimino)-3.4-dimethyl-N-(2-carboxyethyl)-3H-thiazoline-5-carboxamide (7c). namely PS-028 (K-i, = 46.5 +/- 5.5 pM).
