Replaces Prod. #: ALX-260-014

Membrane permeable inhibitor of calpain I and II, cathepsin L and cathepsin K (IC50=0.11 nM). Promotes neurite elongation in differentiating PC12 cells. Prevents Ca2+-ionophore induced degradation of actin binding protein and P235 in platelets. Inhibits myosin light chain phosphorylation in platelets stimulated by collagen, ionomycin (Prod. No. ALX-450-006) or thrombin. Inhibits LPS induced iNOS transcription and NF-κB activation, possibly via proteasome inhibition.
