Product Introduction

OTS514 hydrochloride is a highly effective TOPK(T-LAK cell-originated protein kinase) inhibitor (IC50: 2.6 nM).
In vitro
OTS514 can inhibit the growth of kidney cancer cell lines (VMRC-RCW, Caki-1, Caki-2, 769-P, and 786-O), in which TOPK was highly expressed (IC50:19.9-44.1 nM)[1]. OTS514 markedly inhibits the growth of TOPK-positive cancer cells. It also shows the significant growth-inhibitory effect on ovarian cancer cell lines (IC50: 3.0-46 nM)[3].
In vivo
In mouse xenograft studies with human lung cancer cells, OTS514 shows certain efficacy but also caused severe hematopoietic toxicity (reduction of red blood cells and white blood cells associated with marked increase in platelets)[2]. Compared with vehicle control (P < 0.001), OTS514 (p.o.) significantly elongated overall survival in the ES-2 abdominal dissemination xenograft model.
Cell Research
Cell lines: CD34+ HSCs. Concentrations: 20 or 40 nM. Incubation Time: 48 h. Method: Cells were cultured in RPMI supplemented with 20% fetal bovine serum and 1×StemSpan CC100.Cells were treated with OTS514 (20 or 40 nM) or OTS964 (100 or 200 nM) for 48 hours.Collected cells were washed with PBS and resuspended in 100 ml of PBS followed by staining with CD41a antibody for 20 min at room temperature.Finally,the cells were washed with PBS again and then analyzed for CD41a staining by flow cytometry.Expression of STAT5 was examined by Western blot with an anti-STAT5 antibody.
Animal Research
Animal: BALB/cSLC-nu/nu mice. Solvent: 5% glucose (i.v.); 0.5% methylcellulose (p.o.). Dosages: 1,2.5,and 5 mg/kg

In Vivo Formulation Calculator (Clear solution)

Please enter your animal experiment information in the following box and click Calculate to obtain the mother liquor preparation method and in vivo formula preparation method:
For example, your dosage is 10 mg/kg,each TargetMol | Animal experiments animal weighs 20 g, and the dosage volume is 100 μL. A total of TargetMol | Animal experiments 10 animals were administered, and the formula you used is 5% TargetMol | reagent DMSO+30% PEG300+5% Tween 80+60% ddH2O. So your working solution concentration is 2 mg/mL.
Mother liquor preparation method: 2 mg of drug dissolved in 50 μLDMSOTargetMol | reagent (mother liquor concentration of 40 mg/mL), if you need to configure a concentration that exceeds the solubility of the product, please contact us first.
Preparation method for in vivo formula: Take 50 μLDMSOTargetMol | reagent main solution, add 300 μLPEG300TargetMol | reagent mix well and clarify, then add 50 more μLTween 80, mix well and clarify, then add 600 more μLddH2OTargetMol | reagent mix well and clarify.
