Z-L-Abu-CONH(CH2)3-morpholine is a cell-permeable dipeptidyl alpha-ketoamide that acts as a potent, highly selective, reversible, and active site inhibitor of Calpain 1 and Calpain 2 (Ki = 140 nM and 41 nM, respectively). A weak inhibitor of cathepsin B (Ki = 6.9 muM). May have a neuroprotective role in the central nervous system following focal ischemia. Also protects against virus-induced apoptotic myocardial injury in mice.
