During our search for topically-active Caspase-1 inhibitors, we identified a novel class of potent inhibitors based on a 1,3,5-trisubstituted uracil motif equipped with an l-aspartate semi-aldehyde derived warhead. In the literature, the majority of Caspase-1 inhibitors possessing the same warhead have been designed and evaluated for oral administration as the ethyl acetal pro-drug form. For our topical

Novel arylsulfonamide ether compounds and pharmaceutical compositions thereof are described. The use of the novel arylsulfonamide ether compounds and pharmaceutical compositions thereof as inhibitors of interleukin-1&bgr; converting enzyme and other cysteine proteases in the ICE family is also decribed. In addition, methods of treating stroke, inflammatory diseases, septic shock, repurfusion injury, Alzheimer's disease, and shigellosis using a compound of the invention or a pharmaceutical composition thereof are described.
A compound, or a pharmaceutically acceptable salt or ester thereof, of formula I:
X—W
wherein X is a caspase-selective structure and W has the structure of
—NH—CH(Y)(Z)
wherein Y is a structure that can form a reversible covalent bond with a caspase; and
Z is selected from a carboxyl moiety or a carboxylic acid mimetic.

propionic acidmoiety as an electrophile for covalent attack by the active‐site cysteine residue of caspase1. The syntheses of several cyanopropanate‐containing small molecules based on the optimized peptidic scaffold of prodrug VX‐765 were accomplished. These compounds were found to be potentinhibitors of caspase1 (IC50 values ≤1 nM). Examination of these novel small molecules against a caspase panel
