Sample solution is provided at 25 µL, 10mM.
K-252c is a cell-permeable, reversible, and ATP-competitive inhibitor of protein kinase C (PKC) and protein kinase A (PKA) with IC50 value of 2.45 μM and 25.7 μM, respectively. This component was inhibits β-lactamase, malate dehydrogenase and chymotrypsin with IC50 values of 8, 8 and 10 μM respectively [1].
Protein kinase is known as kinase enzymes that modify other proteins by chemically adding phosphate groups to them (phosphorylation). Phosphorylation can result in a functional change of the target protein (substrate) by changing enzyme activity, cellular location, or association with other proteins in the cells. PKA and PKC are important family member of AGC kinases.
K-252a was previously shown to block nerve growth factor (NGF)-induced neurite outgrowth and the changes in protein phosphorylation elicited by NGF in PC12h cells [2].
The effect of K-252c was also investigated on the severe combined immunodeficient (SCID) mouse-human skin model of psoriasis. It was shown that psoriasis significantly improved after 2 weeks treatment of K-252c [3].

Working concentration: mg/ml;
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 saline, 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.
