The present invention is concerned with novel compounds of formula (I) which are inhibitors of a membrane tripeptidyl peptidase responsible for the inactivation of endogenous neuropeptides such as cholecystokinis (CCKs). The invention further relates to methods for preparing such compounds, pharmaceutical compositions comprising said compounds as well as the use as a medicine of said compounds.

IRL 3461, N-butanesulfonyl- [N-(3,5-dimethylbenzoyl) -N-methyl-3-[4-(5-isoxazolyl)-phenyl]-alanyl]-(L)-valineamide, a potent and bifunctional (ETA+ETB) [Ki(ETA)= 1.8 nM, Ki(ETB)= 1.2 nM] antagonist was discovered by structural modification of IRL 2500, an ET, selective antagonist. IRL 3461 was found to be stable on incubation with human, rat, mouse, and guinea pig plasmas. (C) 1998 Elsevier Science Ltd. All rights reserved.

We have systematically explored the structure-activity relationship (SAR) for a series of compounds 2 as inhibitors of tripeptidyl-peptidase II (TPP II), a serine protease responsible for the degradation of cholecystokinin-8 (CCK-8). This SAR evaluation of the core structure 2 suggest a fairly restrictive pharmacophore for such related structures, but has yielded a limited set of compounds (2b, 2c, 2d, 2s, and 2t) with potent TPP II inhibitory activity (IC50 4-11 nM).
