Use | SKI-178 is a sphingosine kinase 1 (SphK1) inhibitor (IC50 = 0.1-1.8 μM). SKI-178 induces prolonged mitosis followed by apoptotic cell death through the intrinsic apoptotic cascade. The sustained activation of CDK1 during prolonged mitosis, mediated by SKI-178 leads to the simultaneous phosphorylation of the prosurvival Bcl-2 family members, Bcl-2 and Bcl-xl, as well as the phosphorylation and subsequent degradation of Mcl-1. SKI-178 is a novel therapeutic agent for the treatment of AML, including multidrug-resistant/recurrent AML subtypes. |
