Description

Description générale

A cell-permeable dipeptidyl α-ketoamide that acts as a potent, highly selective, reversible, and active site inhibitor of calpain-1 and -2 (K_i = 140 nM and 41 nM, respectively). Weakly inhibits cathepsin B (K_i = 6.9 µM). Reported to have a neuroprotective role in the central nervous system following focal ischemia. Also protects against virus-induced apoptotic myocardial injury in mice.

A cell-permeable dipeptidyl a-ketoamide that acts as a potent, highly selective, reversible, active site inhibitor of calpain-1 (K_i = 140 nM) and calpain-2 (K_i = 41 nM). Weakly inhibits cathepsin B (K_i = 6.9 µM). Shown to inhibit calpain-m-mediated degradation of neurofilament protein (NFP) (IC₅₀ = 600 nM). Also shown to exhibit neuroprotective effects in the central nervous system following focal ischemia. Reported to protect against reovirus-induced myocarditis in mice.
