Description: SJA6017, also known as Calpain Inhibitor VI, is a calpain inhibitor (calpain-1; IC50 = 7.5 nM) and m-calpain (calpain-2; IC50 = 78 nM). It also inhibits cathepsins B and L (IC50s = 15 and 1.6 nM, respectively). Treatment with SJA6017 reduces apoptotic cell death, preserves spinal cord tissue and improves functional outcome. Treating calpain-induced apoptosis with this agent may be a feasible therapeutic strategy for patients with spinal cord injury.
