, Y and Z are set forth in the specification, as well as hydrates, solvates or pharmaceutically acceptable salts thereof. Also described are methods for preparing the compounds of Formula I. The novel compounds of the present invention are potent inhibitors of proteases, especially trypsin-like serine proteases, such as chymotrypsin, trypsin, plasmin and urokinase. Certain of the compounds exhibit direct, selective inhibition of urokinase, or are intermediates useful for forming compounds having such activity.

A study of the S1 binding of lead 5-methylthiothiophene amidine 3, an inhibitor of urokinase-type plasminogen activator, was undertaken by the introduction of a variety of substituents at the thiophene 5-position. The 5-alkyl substituted and unsubstituted thiophenes were prepared using organolithium chemistry. Heteroatom substituents were introduced at the 5-position using a novel displacement reaction of 5-methylsulfonylthiophenes and the corresponding oxygen or sulfur anions. Small alkyl group substitution at the 5-position provided inhibitors equipotent with 3 but possessing improved solubility. (C) 2002 Elsevier Science Ltd. All rights reserved.
