Synthesis of thiophene-2-carboxamidines containing 2-amino-thiazoles and their biological evaluation as urokinase inhibitors
摘要:
The serine protease urokinase (uPa) has been implicated in the progression of both breast and prostate cancer. Utilizing structure based design, the synthesis of a series of substituted 4-[2-amino- 1,3-thiazolyl]-thiophene-2-carboxamidine is described. Further optimization of this series by substitution of the terminal amine yielded urokinase inhibitors with excellent activities. (C) 2001 Elsevier Science Ltd. All rights reserved.

The present invention is directed to compounds of Formula I:
wherein X is O, S or NR7 and R1-R7, 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.

straightforward solid-phase synthesis of 2-aminoimidazolone derivatives is described. The synthesis starts with immobilization of thioureas onto solid support, followed by HBTU/DIEA assisted coupling of Boc-protected aminoacids. Upon removal of the Boc group, intramolecularcyclization and simultaneous cleavage are promoted by polyamine resin to give the 2-aminoimidazolone derivatives in good yields and excellent
