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.

Animal A (mg/kg) = Animal B (mg/kg) multiplied by | Animal B Km |
Animal A Km |
For example, to modify the dose of Compound A used for a mouse (20 mg/kg) to a dose based on the BSA for a rat, multiply 20 mg/kg by the Km factor for a mouse and then divide by the Km factor for a rat. This calculation results in a rat equivalent dose for Compound A of 10 mg/kg.
