SKI II is an inhibitor of sphingosine kinase with IC50 value of 0.5μM[1].
SKI II is selective against SK and has no inhibition of human protein kinases ERK2, PKC-I and the lipid kinase PI3K. It is reported that SKI II is not a competitive inhibitor at the ATP-binding site of SK. SKI II also inhibits endogenous SK in intact MDA-MB-231 cells [1].
As a SK inhibitor, SKI II prevents SK from catalyzing the generation of sphingosine 1-phosphate (S1P). The blockage of S1P formation leads to inhibition of proliferation, as well as the induction of apoptosis in cancer cells. SKI II shows cytotoxicity in T-24 human bladder carcinoma cells, MCF-7 human breast adenocarcinoma cells and the subline of MCF-7 cells, MCF-7/VP, with IC50 values of 4.6μM, 1.2μM and 0.9μM, respectively [1].

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.
