Calpain Inhibitor XII

Calpain inhibitor XII is a reversible and selective inhibitor of calpain I (µ-calpain, Ki = 19 nM), with lower affinities for calpain II (m-calpain, Ki = 120 nM) and cathepsin B (Ki = 750 nM). Calpain inhibitors, including this compound, have been used to study the role of calpains in diverse processes, including neutrophil chemotaxis, neuronal signaling, and cardiac response to injury.Formal Name: [3-methyl-1-[[[1-[oxo[(2-pyridinylmethyl)amino]acetyl]butyl]amino]carbonyl]butyl]-carbamic acid, phenylmethyl ester.
