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[1]. OTS514 induces cell cycle arrest and apoptosis[2].

IC50 & Target

IC50: 2.6 nM (TOPK)[1]
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].

MCE has not independently confirmed the accuracy of these methods. They are for reference only.

Cell Viability Assay[2]

Cell Line: Human myeloma cell lines (MM1.S, MM1.R, RPMI 8226, 8226Dox40, KMS34, KMS34CFZ, KMS11, JJN3, LP-1, NCI H929, U266B1)
Concentration: 1.5625, 3.125, 6.25, 12.5, 25, 50, and 100 nM
Incubation Time: 72 hours
Result: IC50 values ranged from 11.6 to 29.4 nM in parental cell lines, indicating a potent inhibitory effect. Only the RPMI 8226-Dox40 cell line, which overexpresses the multi-drug resistance transporter gene ABCB1, is resistant.
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].

MCE has not independently confirmed the accuracy of these methods. They are for reference only.

Animal Model: Female BALB/cSLC-nu/nu mice bearing a xenograft model of A549 cells[1]
Dosage: 1, 2.5, and 5 mg/kg
Administration: Intravenously treated; once every day for 2 weeks
Result: Resulted in tumor growth inhibition (TGI) of 5.7, 43.3, and 65.3% on day 15, respectively, without any body weight loss.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
