Procaspase-6 inhibitor 13 is a small molecule, noncovalent, allosteric inhibitor of procaspase-6 with KD of 0.38 uM.Procaspase-6 inhibitor 13 binds to pro-C6 at the dimer interface and contacts amino acids Y198, T199 and E214.Procaspase-6 inhibitor 13 significantly stabilizes procaspase-6.

MMPSI is a potent and selective small molecule caspase 3 and caspase 7 inhibitor with an IC50 of 1.7 μM for human caspase-3. MMPSI can significantly reduce ischemia-reperfusion-induced infarct size in the isolated rabbit heart, and reduce apoptosis in both the ischemic myocardium and isolated cardiomyocytes. MMPSI can be used for researching cardioprotection.

AC-VEID-CHO (TFA) is a peptide-derived caspase inhibitor and has potency of inhibition for Caspase-6, Caspase-3 and Caspase-7 with IC50 values of 16.2 nM, 13.6 nM and 162.1 nM, respectively. AC-VEID-CHO (TFA) can be used for the research of neurodegenerative conditions including Alzheimer’s and Huntington’s disease.

Z-LEVD-FMK is a cell-permeable caspase-4 inhibitor. Z-LEVD-FMK blocks ER stress-induced apoptosis in cancer cells.

M867 is a selective and reversible inhibitor of caspase-3 with an IC50 of 1.4 nM and Ki of 0.7 nM. M867 has anti apoptotic activity.
