Biological Activity

OTS-964 is a dimethylated derivative of OTS514 and potent, selective TOPK inhibitor with IC50 of 28 nM, exhibits excellent in vivo efficacy with liposomal formulation.
OTS-964 inhibits the growth of TOPK-positive cells with low IC50 values (A549 IC50=31 nM), decreases autophosphorylation of TOPK (Thr9), as well as phosphorylation of histone H3 (Ser10), in both T47D and LU-99 cells.
The liposomal OTS964 causes complete regression of tumors without any detectable toxicity in the xenograft models.
