Description:OTS514 is a highly potent TOPK inhibitor with an IC50 of 2.6 nM. OTS514 strongly suppresses the growth of TOPK-positive cancer cells. OTS514 induces cell cycle arrest and apoptosis.

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[2].

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)[1].
