title: Novel, potent non-covalent thrombin inhibitors incorporating p(3)-lactam scaffolds.
abstract: Evolution of P(1)-argininal inhibitor prototypes led to a series of non-covalent P(3)-7-membered lactam inhibitors 1a-w, featuring novel peptidomimetic units that probe each of the S(1), S(2), and S(3) specificity pockets of thrombin. Rigid P(1)-arginine surrogates possessing a wide range of basicity (calcd pK(a)'s approximately neutral-14) were surveyed. The design, synthesis, and biological activity of these targets are presented.
