| Description | Calpain Inhibitor I,ALLN 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 | |||||
| Targets | calpain I | calpain II | cathepsin B | cathepsin L | ||
| IC50 | 190 nM(Ki) | 220 nM(Ki) | 150 nM(Ki) | 500 nM(Ki) | ||
| 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].

天然产物，大多都有颜色，
存在干扰，多数情况下需要做样品的阴性对照，
尽量能用荧光的方法，
之前我们做过，将两个试剂盒的方法合并后，做的，
效果还可以

RMgX + RX = R-R + MgX2.
这个反应需要的能量比生成格氏试剂的高，
因此降低反应温度是第一个选择。
其次， 增加镁得摩尔比， 让 RX与镁有更多机会反应， 而不是与RMgX。
第三， 降低RX的浓度, 即用更多的溶剂， 因为溶剂和格氏试剂有很显著的溶剂络合。
第四， 缓慢滴加RX.， 即降低RX.在反应体系的浓度。
第五， 增加搅拌速率， 即， 让RX.与镁有更好的接触。
