General description
A cell-permeable, ATP competitive, reversible indolizinoquinoxalin derivative that acts as a specific inhibitor of T-LAK-cell-originated protein kinase (TOPK/PBK)(IC50 = 2 µM). Does not affect the activities of ERK1, JNK1, and p38 MAP kinases. At higher concentrations (~ 5 µM) also inhibits MEK1 activity. Shown to suppress the proliferation of HCT116 colon cancer cell line and block tumor growth in colon cancer xenograft models in a dose-dependent manner. Diminishes TOPK activity only in cells over-expressing TOPK without significantly affecting cells with low levels of expression. Also shown to increase the expression of p53, active caspase-7, cleaved poly-ADP-Ribose polymerase, and increase the phosphorylation of Cdc2.
