title: Selective urokinase-type plasminogen activator (uPA) inhibitors. Part 2: (3-Substituted-5-halo-2-pyridinyl)guanidines.
abstract: Based on previous modeling predictions, a series of (3-substituted-5-chloro-2-pyridinyl)guanidines have been designed with good potency and selectivity for urokinase-type plasminogen activator (uPA). Compound 36 has a K(i) of 0.17 microM and greater than 300-fold selectivity with respect to tPA and plasmin.
