4.15mg/ml Taking the 1 mL working solution as an example, add 50 μL of 83 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. 
* <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.
* Room temperature shipping (Stability testing shows this product can be shipped without any cooling measures.)

Biological Activity

Description CB-5083 is a potent, selective, and orally bioavailable p97 AAA ATPase inhibitor with IC50 of 11 nM. Phase 1.
Targets
p97 AAA ATPase [1]
(Cell-free assay)
11 nM
In vitro In A549 cells, CB-5083 causes significant K48 poly-ubiquitinated protein and CHOP accumulation as well as p62 reduction, and kills tumor cells with IC50 of 680 nM. [1]
In vivo In mice bearing human HCT 116 colon tumor xenografts, CB-5083 (75 mg/kg, p.o.) significantly inhibits tumor growth. In mice bearing established human AMO-1 multiple myeloma and A549 lung carcinoma tumor xenografts, CB-5083 (100 mg/kg, p.o.) also results in significant tumor growth inhibition. [1]

Protocol (from reference)

Kinase Assay:[1]
  • ATPase assay

    Compounds are diluted in DMSO with a 3-fold 10-point serial dilution starting at 10 μM. The assay is done in a 384-well plate with each row as a single dilution series with duplicate of each compound concentration point. In 5 μL total volume, 20 nM p97 hexameric enzyme and 20 μM ATP are added to start the reaction. The plate is sealed and incubated at 37 °C for 15 min after mixing thoroughly in an orbital shaker. Compound dilution, ATP and enzymes addition are conducted with automated liquid handling using the Freedom Evo. ADP Glo reagents 1 and 2 are added according to the manufacturer’s protocol. The luminescence is measured by Envision plate reader as the end point of the reaction. The IC50 of each compound is derived by fitting the luminescence values to a four-parameter sigmoidal curve.
Cell Assay:[1]
  • Cell lines

    A549 cells

  • Concentrations

    ~40.0 μM

  • Incubation Time

    72 h

  • Method

    A549 and other tumor cell lines are cultured according to ATCC guidelines. Cells are cultured in black or white, clear-bottomed, tissue culture-treated 384-well plates. Cells are treated with 10-point dose titration of the compound in well duplicates. After a 72 h treatment, CellTiter-Glo is added to the white plates to measure cell viability. Luminescence values are fit to a four-parameter sigmoidal curve to determine IC50 concentrations.
Animal Study:[1]
  • Animal Models

    Nu/Nu nude female mice bearing human HCT 116 colon tumor xenografts

  • Dosages

    75 mg/kg, qd

  • Administration

    p.o.
