Abstract:
-Hydroxy- and -ketoester functionalized D-Phe-Pro-Lys tripeptides were found to be potent thrombin active site inhibitors. The ketoester derivatives were characterized by slow binding kinetics. The most potent of the series was 9 (BMS 181, 412) with an overall inhibition constant Ki* of 0.0017 μM.
