In vitro study | Calpeptin inhibits 20K phosphorylation in a dose-related manner in platelets stimulated by thrombin, ionomycin or collagen. In differentiating PC12 cells, Calpeptin promotes neurite elation via inhibition of Calpain activity. In rat retinal ganglion cells, Calpeptin atenates apoptosis, maintenance normal whole-cell membrane potential, and thus provide functional neuroprotection. Calpeptin in coagulation Blood enzyme, ionomycin or collagen-stimulated platelets dose-dependently inhibited 20K phosphorylation. In differentiated PC12 cells, Calpeptin promotes neurite elongation by inhibiting calpain activity. In rat retinal ganglion cells, Calpeptin attenuates apoptosis and maintains normal whole-cell membrane potential, thereby providing functional neuroprotection. |
In vivo study | 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. In a rat focal cerebral ischemia-reperfusion injury model Calpeptin reductions the neural apotosis in hippocampal CA1 sector via inhibition of the expression of Caspase-3. In the feline right ventricular (RV) PO (RVPO) model, calpeptin (0.6 mg/kg, I. v.) blocks the activation of calpain and caspase-3 and the cleavage of their substrates, as well as the programmed death of cardiomyocytes. In a rat model of focal cerebral ischemia-reperfusion, Calpeptin reduced neuronal apoptosis in the hippocampal CA1 region by inhibiting expression by Caspase-3. |

biological activity | Calpeptin is an effective, cell permeability calpain inhibitor. The ID50 of calpain I (porcine red blood cell), calpain II (porcine kidney), papain, and calpain I (human platelet) are 52 nM,34 nM, respectively, 138 nM, and 40 nM. Calpeptin is an effective, cell permeability calpain inhibitor. its ID50 for calpain I (porcine red blood cells), calpain II (porcine kidney), papain, and calpain I (human platelets) is 52 nM,34 nM,138 nM, and 40 nM, respectively. Calpeptin can reduce apoptosis and intracellular inflammatory changes in muscle cells. |

in vivo studies | in a fine 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. In a rat focus cerebral ischemia-reperfusion injury model, Calpeptin reduces the neuronal apoptosis in hippocampal CA1 sector via inhibition of the expression of Caspase-3. in the right ventricle (RV) PO (RVPO) model of cats, the calpeptin (0.6 mg/kg, I. v.) blocks the activation of calpain and caspase-3 and the lysis of its substrate, as well as the programmed death of myocardial cells. In the rat model of regional cerebral ischemia-reperfusion, Calpeptin reduce neuronal apoptosis in hippocampal CA1 region by inhibiting the expression of Caspase-3. |
