Information
OTS514 hydrochloride OTS514 is a highly potent TOPK(T-LAK cell-originated protein kinase) inhibitor with an IC50 value of 2.6 nM. OTS514 induces cell cycle arrest and apoptosis .
Targets
TOPK (Cell-free assay) 2.6 nM
In vitro
OTS514 has growth inhibitory effect on five kidney cancer cell lines, VMRC-RCW, Caki-1, Caki-2, 769-P and 786-O, in which TOPK was highly expressed. The IC50 values range from 19.9 to 44.1 nM. OTS514 strongly suppressed the growth of TOPK-positive cancer cells. It also shows significant growth-inhibitory effect on ovarian cancer cell lines with IC50 values of 3.0 to 46 nM.
In vivo
Mouse xenograft studies with human lung cancer cells demonstrated the in vivo efficacy of OTS514 but found that the compound also caused severe hematopoietic toxicity [reduction of red blood cells (RBCs) and white blood cells (WBCs) associated with marked increase in platelets]. Oral administration of OTS514 significantly elongated overall survival in the ES-2 abdominal dissemination xenograft model, compared with vehicle control (P < 0.001).
