In vivo Batch:
Homogeneous suspension	CMC-NA	≥5mg/ml	Taking the 1 mL working solution as an example, add 5 mg of this product to 1 ml of CMC-Na solution, mix evenly to obtain a homogeneous suspension with a final concentration of 5 mg/ml.
Clear solution	5%DMSO 1 40%PEG300 2 5%Tween80 3 50%ddH2O Validated by Selleck labs. Should you need adjustments to this formulation, contact our sales team for custom testing.	5.000mg/ml (9.99mM)	Taking the 1 mL working solution as an example, add 50 μL of 100 mg/ml clarified DMSO stock solution to 400 μL of PEG300, mix evenly to clarify it; add 50 μL of Tween80 to the above system, mix evenly to clarify; then continue to add 500 μL of ddH2O to adjust the volume to 1 mL. The mixed solution should be used immediately for optimal results.

Method for preparing DMSO master liquid: mg drug pre-dissolved in μL DMSO ( Master liquid concentration mg/mL, Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug. )

Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH₂O, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such as vortex, ultrasound or hot water bath can be used to aid dissolving.

Mechanism of Action

Features	Allosteric, HSET-selective inhibitor.
Targets/IC₅₀/Ki	HSET 75 μM
In vitro	CW069 increases multipolar spindles in N1E-115 cells with supernumerary centrosomes without altering bipolar spindle morphology in normal human dermal fibroblast cells. This compound inhibits growth in cancer N1E-115 cells with IC50 of 10 μM, but not in NHDF or primary human bone marrow cells.
Kinase Assay	In Vitro Enzymatic ATPase Assay
Kinase Assay	The protocol is optimized for use with full-length, N-terminal, 6His-tagged HSET and KSP, and measured the MT-stimulated activity of the proteins. Inhibition of the Gsp synthetase activity of HSET/KSP is observed spectrophotometrically by coupling the hydrolysis of ATP to oxidation of NADH via pyruvate kinase/lactate dehydrogenase reactions. The assay is initiated by adding purified Gsp synthetase/amidase (12.8 nM) to an assay mixture containing the following components (final concentration): 6 nM protein, 0.07 mg/ml MTs (University Biologicals), 1.56 mM glutathione, 10 mM spermidine, 2 mM ATP, 2.7 mM MgCl₂, 1 mM phospho(enol)-pyruvate, 0.2 mM NADH, 50 μg/ml lactate dehydrogenase, 100 μg/ml pyruvate kinase, and various concentrations of this compound all in 50 mM Na PIPES (pH 6.8) at 37°C. The ADP-Glo detection assay (Promega) is performed as described in the manufacturer’s instructions. All compound additions were performed using a multidrop BioMek Nxp. Plates were read using a Pherastar microplate reader.
