Clear solution	5%DMSO 1 40%PEG300 2 5%Tween80 3 50%ddH2O	0.8mg/ml	Taking the 1 mL working solution as an example, add 50 μL of 16 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.
Clear solution	5%DMSO 1 Corn oil	0.5mg/ml	Taking the 1 mL working solution as an example, add 50 μL of 10 mg/ml clear DMSO stock solution to 950 μL of corn oil and mix evenly. The mixed solution should be used immediately for optimal results.

* <1 mg/ml means slightly soluble or insoluble.
* Please note that Selleck tests the solubility of all compounds in-house, and the actual solubility may differ slightly from published values. This is normal and is due to slight batch-to-batch variations.

生物活性

製品説明	Prexasertib(LY2606368) is an ATP-competitive CHK1 inhibitor with a Ki value of 0.9 nmol/L. For CHK2 and RSK, its IC50 values are 8 nM and 9 nM respectively in cell-free assay.
in vitro	In nonclinical studies, LY2606368 induced DNA damage as measured by replication catastrophe and increases in pH2A.X, a marker of double-stranded DNA breaks^[1]. Treatment of cells with LY2606368 results in the rapid appearance of TUNEL and pH2AX-positive double-stranded DNA breaks in the S-phase cell population. In a functional assay, LY2606368 potently abrogated the G2–M checkpoint activated by doxorubicin in p53-deficient HeLa cells with an EC50 of 9 nmol/L. LY2606368 was broadly antiproliferative with IC50 values typically <50 nmol/L in the most sensitive cell lines with a minority of cell lines showing considerable resistance with IC50's >1,000 nmol/L. LY2606368 requires CDC25A and CDK2 to cause DNA damage^[2].
in vivo	LY2606368 inhibited tumor growth in cancer xenografts as monotherapy and in combination with other agents^[1]. In an orthotopic SKOV3 ovarian cancer model, LY2606368 was shown to inhibit the growth of primary tumors and significantly reduce the incidence of metastases and ascites accumulation. LY2606368 also demonstrated efficacy in an SW1990 orthotopic pancreatic cancer model resulting in a 92% inhibition of primary tumor growth and the elimination of metastases to the lymphnode, spleen, and intestine^[3].

	実験の流れ	HeLa cells were plated onto T25 flasks and allowed to recover for 24 hours. LY2606368 was then added to give final concentrations of 33 or 100 nmol/L. In some experiments, 20μmol/L Z-VAD-FMK was included during the drug treatment. Cells were treated for 12 hours, and during the last 2 hours, colchicine was added to 1 μg/mL. Fixation of nuclei for metaphase spreads was done following the method of Bayani and Squire. Chromosome spreads were done. A 12-μL volume of cell suspension in 3:1 methanol/acetic acid fixative was dropped from a height of 3 cm onto dry glass slides or coverslips. The slides were then heated for 45 seconds on a 43°C metal block, before being removed to allow drying to complete at room temperature. Coverslips were mounted on slides with Vectashield Hard Set mounting medium with DAPI. Slides were examined with a Leica DMR fluorescence microscope and images were captured using a SPOT RT3 Slider camera.
