Cell experiment [1]: | |
Cell lines |
DLD1-TRAIL/R cells |
Preparation method |
The solubility of this compound in DMSO is >10 mM. General tips for obtaining a higher concentration: Please warm the tube at 37℃ for 10 minutes and/or shake it in the ultrasonic bath for a while. Stock solution can be stored below -20℃ for several months. |
Reaction Conditions |
0, 10, 20 and 50 μM; 96 hrs |
Applications |
In DLD1-TRAIL/R cells, Calpain Inhibitor I combined with Ad/gTRAIL induced cell death dramatically while Calpain Inhibitor I or Ad/gTRAIL alone only had minimal killing effects. |
Animal experiment [2]: | |
Animal models |
Splanchnic artery occlusion (SAO)-shocked rats |
Dosage form |
15 mg/kg; i.p. |
Applications |
Calpain Inhibitor I, given intraperitoneally 30 mins before ischemia at a dose of 15 mg/kg, significantly reduced IκB-α degradation, the intensity of P-selectin/ICAM-1 in the reperfused ileum, neutrophil infiltration as well as malondialdehyde levels. Meanwhile, pretreatment of Calpain Inhibitor I markedly improved mean arterial blood pressure and the histological status of the reperfused tissue. |
Other notes |
Please test the solubility of all compounds indoor, and the actual solubility may slightly differ with the theoretical value. This is caused by an experimental system error and it is normal. |

Calpain Inhibitor I is an inhibitor of calpain I, calpain II, cathepsin B and cathepsin L with Ki values of 190 nM, 220 nM, 150 nM and 500 pM, respectively.
Calpain inhibitor I combined with Ad/gTRAIL induced cell death dramatically in DLD1-TRAIL/R cells, while calpain alone had only minimal killing effects. The combination of calpain inhibitor I and TRAIL protein resulted in cleavage of both caspase-8 and caspase-3 to active subunits [1].
Calpain inhibitor I treated male Sprangue-Dawley rats have seen reductions of P-selectin/ICAM-1 expression, neutrophil infiltration, lipid peroxidation, nitrotyrosine, PAR formation as well as IκB-α degradation [2].

Method for preparing DMSO master liquid: mg drug pre-dissolved in μL DMSO ( Master liquid concentration mg/mL, Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug. )
Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O, mix and clarify.
Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.
Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such as vortex, ultrasound or hot water bath can be used to aid dissolving.
