Interaction with the S1 beta-pocket of urokinase: 8-heterocycle substituted and 6,8-disubstituted 2-naphthamidine urokinase inhibitors.
2004
Several 8-substituted 2-naphthamidine-based inhibitors of the serine protease urokinase plasminogen activator (uPA) are described. Direct attachment of five-membered saturated or unsaturated rings improved inhibitor performance; substitution with sulfones further improved binding profiles. Combination of these substituents or of previously described NH-linked heteroaromatic rings with 6-phenyl amide substituents provided further enhancements to potency and selectivity.
