Application

Calpain Inhibitor II has been used in western blotting. It has also been used to study the mechanism of Spy1A (a cyclin-like protein) degradation during cell cycle.
Calpain inhibitor II is a cell-permeable peptide that restricts the activity of calpain, cathepsin L and cathepsin B. Calpain inhibitor II also prevents the methylmercury-induced cell death of cultured rat cerebellar neurons.

Biochem/physiol Actions

Calpain is a cysteine protease expressed in the nervous system. Calpain exhibits a calcium-dependent enzyme activity. In mice models, inhibition of calpain prevents leukocyte infiltration induced by angiotensin II and also attenuates prevascular inflammation.

In this study, 22 new betulinic acid (BA) derivatives were synthesized and tested for their inhibition of the chymotrypsin-like activity of 20S proteasome. From the SAR study, we concluded that the C-3 and C-30 positions are the pharmacophores for increasing
