Cayman MX1013

MX1013 is a dipeptide pan-caspase inhibitor that inhibits caspase-1 (IC₅₀ = 20 nM), caspase-3 (IC₅₀ = 30 nM), and caspase-6, -7, -8, and -9 (IC₅₀s = 5-18 nM). It is selective for caspases over calpain I, cathepsin B, cathepsin D, renin, thrombin, and Factor Xa (IC₅₀s = >10 μM). MX1013 (0.05 μM) inhibits anti-Fas antibody-induced caspase-3 processing and poly(ADP)ribose polymerase (PARP) cleavage in Jurkat cells, indicating inhibition of apoptosis. It increases survival in a mouse model of anti-Fas antibody-induced liver failure when administered at doses of greater than or equal to 0.25 mg/kg. MX1013 reduces infarct size in rat models of acute myocardial infarction-reperfusion or transient focal brain ischemia-reperfusion injury when administered intravenously as a 20 mg/kg bolus dose followed by a 5 mg/kg per hour infusion.
