Paired basic amino acid cleaving enzyme 4 (PACE4), a serine endoprotease of the proprotein convertases family, has been recognized as a promising target for prostate cancer. We previously reported a selective and potent peptide-based inhibitor for PACE4, named the multi-Leu peptide (Ac-LLLLRVKR-NH2 sequence), which was then modified into a more potent and stable compound named C23 with the following structure: Ac-dLeu-LLLRVK-Amba (Amba: 4-amidinobenzylamide). Despite improvements in both in vitro and in vivo profiles of C23, its selectivity for PACE4 over furin was significantly reduced. We examined other Arg-mimetics instead of Amba to regain the lost selectivity. Our results indicated that the replacement of Amba with 5-(aminomethyl)picolinimidamide increased affinity for PACE4 and restored selectivity. Our results also provide a better insight on how structural differences between S1 pockets of PACE4 and furin could be employed in the rational design of selective inhibitors.

In this account, we describe the development of an efficient and convergent process for the peptidomimetic thrombin inhibitor 1 on production plant scale. Starting from nicotinonitrile (13), (2S,4R)-1-(tert-butoxycarbonyl)-4-hydroxy-2- pyrrolidinecarboxylic acid (5) and (2R)-2-amino-3-cyclohexylpropanoic acid (29) compound 1 was obtained in 16 chemical steps. New methods had been developed for the preparation of the key intermediate dehydroproline 22 and the transformation of nitriles into amidines. The thrombin inhibitor 1 was isolated by special techniques (nanofiltration and spray drying). Almost all salts of 1 are amorphous, however, a crystalline complex was obtained with 1,2-benzisothiazol-3(2H)-one 1,1-dioxide (Saccharin).

There is provided a compound of formula I wherein Ra, R1, R2, Y and R3 have meanings given in the description and pharmaceutically acceptable derivatives (including prodrugs) thereof, which compounds and derivatives are useful as, or are useful as prodrugs of, competitive inhibitors of trypsin-like proteases, such as thrombin, and thus, in particular, in the treatment of conditions where inhibition of thrombin is required (e.g. thrombosis) or as anticoagulants.
