LN229 GBM cell lysates were immunoblotted with antibodies recognizing specific focal adhesion proteins. Note the decreased levels of Cas, paxillin, and FAK tyrosine phosphorylation in cells treated with CB-5083. In addition, CB-5083 treatment leads to decreased levels of total PTP-PEST expression, but Vcp protein expression levels are not impacted.

Incubation with VCP inhibitors results in activation of Unfolded Protein Response (UPR). SKOV3 cells were incubated with (C) 2.5 μM CB-5083 for 0, 1, 3, 6, 12, 24 and 48 h. Whole cell lysates were subjected to Western blot analysis and probed for UPR-related proteins

Cycloheximide (CHX) chase experiments in the presence of the unrelated competitive p97 inhibitor CB-5083 (5 μm) or DMSO alone. Cells were lysed at indicated time points after CHX addition and lysates subjected to Western blotting. Tubulin was probed as loading control. UT = untreated.

|Description||CB-5083 is a potent, selective, and orally bioavailable p97 AAA ATPase inhibitor with IC50 of 11 nM. Phase 1.|
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. 
|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. |
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.

For best results, use promptly after mixing.
* 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.
Calculate the mass, volume or concentration required for a solution. The Selleck molarity calculator is based on the following equation:
Mass (mg) = Concentration (mM) × Volume (mL) × Molecular Weight (g/mol)
*When preparing stock solutions, please always use the batch-specific molecular weight of the product found on the via label and MSDS / COA (available on product pages).
Calculate the dilution required to prepare a stock solution. The Selleck dilution calculator is based on the following equation:
Concentration (start) x Volume (start) = Concentration (final) x Volume (final)
This equation is commonly abbreviated as: C1V1 = C2V2 ( Input Output )
* When preparing stock solutions always use the batch-specific molecular weight of the product found on the vial label and MSDS / COA (available online).

Definitions of molecular mass, molecular weight, molar mass and molar weight:
Molecular mass (molecular weight) is the mass of one molecule of a substance and is expressed in the unified atomic mass units (u). (1 u is equal to 1/12 the mass of one atom of carbon-12)
Molar mass (molar weight) is the mass of one mole of a substance and is expressed in g/mol.
