J. Cacciola et al., SYNTHESIS OF CONFORMATIONALLY-RESTRICTED BOROPEPTIDE THROMBIN INHIBITORS, Bioorganic & medicinal chemistry letters, 6(3), 1996, pp. 301-306
A series of boropeptide thrombin inhibitors was prepared in which the
P3 residues of 2 (Ac-(D)-Phe-Pro-boroLys-OH . HCl) and 3 (3-Phenylprop
ionyl-Pro-borolys-OH . HCl) were replaced by conformationally-restrict
ed, benzoic acid-derived residues 4. The potent binding affinity of th
e resulting inhibitors such as 10 may be due in part to a unique mode
of binding in the thrombin active site.
