Peptidomimetic compounds possessing a caprolactam ring constraint were prepared and evaluated as interleukin-1 beta converting enzyme (ICE) inhibitors. The caprolactam ring was used to constrain the P3 region of our inhibitors. This strategy proved to be effective for the synthesis of ICE inhibitors, maintaining key hydrogen bond interactions with the enzyme and invoking a preferred conformation for binding. Several compounds exhibited IC50 values less than 10 nM in a caspase-1 enzyme assay and less than 100 nM in a THP-1 whole cell assay measuring IL-1 beta production. Two compounds, 13c and 13j, were found to have good oral bioavailability (> 50%) in rats when administered as prodrugs. (c) 2006 Elsevier Ltd. All rights reserved.

The present invention relates to interleukin - Iβ converting enzyme inhibitors
of formula I: wherein each X is independently selected from: i) -C(W)2-;
ii) -C(O)-; iii) -NR2-; iv) -S-; v) -S(O)-; vi) -S(O)2-;
vii) two units, one from each adjacent X unit, can be taken together to form a substituted
or unsubstituted double bond having the formula -CW=CW-; wherein
each W is hydrogen of a unit having the formula -(L2)j-R2,
the index j is 0 or 1;R is a carbocyclic or heterocyclic aryl ring; R1
is a cysteine trap; each R2 is independently a suitable substituent;
and L, L1, and L2 are linking units.
