Calpain Inhibitor-1 (compound 36) is a highly potent and selective inhibitor of Calpain 1 (Cal1), which is a cysteine protease. It exhibits an IC50 value of 100 nM and a Ki value of 2.89 μM.
ALLM (Calpain inhibitor II), a potent calpain and cathepsin protease inhibitor, not only prevents neuronal cell death but also enhances chronic neurological function following spinal cord injury (SCI)[1][2].
SJA6017 is a inhibitor of calpain-1 (IC50 = 7.5 nM) and calpain-2 ( IC50 = 78 nM). SJA6017 also inhibits cathepsins B (IC50s = 15 nM) and cathepsins L (IC50s = 1.6 nM). SJA6017 reduces apoptotic cell death, preserves spinal cord tissue and improves functi
Pheleuin is a pyrazinone derivative synthesized from a dipeptide aldehyde. Although the biological activity of this compound has not been reported, similar diketopiperazines are known to inhibit calpain and or regulate S. aureus virulence factor expression.
