Description | Calpeptin is a potent, cell-permeable calpain inhibitor. |
Targets&IC50 | Calpain I (porcine erythrocytes):52 nM(ID50), Papainb:138 nM(ID50), Calpain II (porcine kidney):34 nM(ID50), Calpain I (human platelets):40 nM(ID50) |
In vitro | Calpeptin inhibits 20K phosphorylation in a dose-related manner in platelets stimulated by thrombin, ionomycin or collagen. [1] In differentiating PC12 cells, Calpeptin promotes neurite elongation via inhibition of Calpain activity. [2] In rat retinal ganglion cells, Calpeptin attenuates apoptosis, maintains normal whole-cell membrane potential, and thus provides functional neuroprotection. [3] |
In vivo | In a feline right ventricular (RV) PO (RVPO) model, calpeptin (0.6 mg/kg, i.v.) blocks the activation of calpain and caspase-3, cleavage of their substrates, and cardiomyocyte programmed cell death. [4] In a rat focal cerebral ischemia–reperfusion injury model, Calpeptin reduces the neuronal apoptosis in hippocampal CA1 sector via inhibition of the expression of Caspase-3. [5] |
