Product Information:

OTS514 is a potent TOPK (T-LAK cell-originated protein kinase) inhibitor. OTS514 exhibits growth suppressive effect on small cell lung cancer. TS514 effectively suppressed growth of SCLC cell lines (IC50 ; 0.4 ~ 42.6 nM) and led to their apoptotic cell death. Treatment with OTS514 suppressed forkhead box protein M1 (FOXM1) activity, which was involved in stemness of CSC. Furthermore, OTS514 treatment reduced CD90-positive SCLC cells and showed higher cytotoxic effect against lung sphere-derived CSC-like SCLC cells.

In Vitro

OTS514 (1.5625-100 nM) induces cell cycle arrest and apoptosis at nanomolar concentrations in a series of human myeloma cell lines (HMCL) and prevents outgrowth of a putative CD138+ stem cell population from multiple myeloma (MM) patient-derived peripheral blood mononuclear cells.

 

In Vivo

OTS514 (1-5 mg/kg; once a day for 2 weeks; intravenous administration) induces tumor regression in a xenograft model of A549 cells (TOPK-positive lung cancer cells).
