Improved procedures have been developed for the synthesis of P1aspartate-based 2,6-dichlorobenzoyloxymethyl ketone 1 and fluoromethylketone 2, the prodrugs of two potent ICE-inhibitors. 1 was prepared from (R)-trans-4,5-O-isopropylidene-4,5-dihydroxy-2-pentenecarboxylic acid ethyl ester; 2 was obtained via a nitro-aldol condensation as key step from in situ generated fluoroacetaldehyde.

proteome. This huge task may be accelerated by using active-site directed probes which profile proteins in an activity-dependent manner. Herein, we have developed a fluorescently-labeled affinityprobe containing chemical reactivity specific towards caspases. Preliminary assays and proof-of-concept experiments demonstrated that this probe exhibits strong chemical reactivity towards caspase-1 over other enzymes

(EN) The present invention is directed to novel dipeptides thereof, represented by general Formula (I) where R1-R3 and AA are defined herein. The present invention relates to the discovery that compounds having Formula (I) are potent inhibitors of apoptotic cell death. Therefore, the inhibitors of this invention can retard or block cell death in a variety of clinical conditions in which the loss of cells, tissues or entire organs occurs.(FR) La présente invention concerne de nouveaux dipeptides représentés par la formule générale (I). Dans cette dernière, R1-R3 et AA sont tels que définis. Les composés présentant la formule (I) sont de puissants inhibiteurs de la mort cellulaire programmée. Par conséquent, les inhibiteurs de la présente invention peuvent retarder ou bloquer la mort cellulaire dans diverses conditions cliniques dans lesquelles peut se produire la perte des cellules, des tissus ou de la totalité des organes.
