|Description||VER-155008 is a potent Hsp70 family inhibitor with IC50 of 0.5 μM, 2.6 μM, and 2.6 μM in cell-free assays for HSP70, HSC70, and GRP78, respectively, >100-fold selectivity over HSP90.|
VER-155008 inhibits the proliferation of human breast and colon cancer cell lines BT474, MB-468, HCT116, and HT29 with GI50s in the range 5.3-14.4 μM, and induces Hsp90 client protein degradation in both HCT116 and BT474 cells. In the 8505C and FRO cells, VER-155008 reduces the cell viability and elevates the percentage of dead cells in a time- and dose- dependent manner. VER-155008 causes a dose-dependent inhibition of cytokine-dependent AML cell proliferation. VER-155008 shows an effective inhibition of cell proliferation in A549 and H1975 cells. 
|In vivo||In HCT116 tumor bearing mice, VER-155008 (25 or 40 mg/kg, i.v.) demonstrates rapid metabolism and clearance, along with tumor levels below the predicted pharmacologically active level.|
|Kinase Assay: ||
Hsc70, Hsp70 and Grp78 ﬂuorescence polarisation (FP) assay:The FP assay for Hsp70 is conducted in aqueous buffer consisting of 100 mM Tris pH 7.4, 150 mM KCl and 5 mM CaCl2, in a final assay volume of 100 µl, using 96 well black polystyrene high bind plates with a Fusion plate reader. N6-(6-amino)hexyl-ATP-5-FAM and the in-house protein preparation of GST-HSP70 3-382 have final concentrations in the assay of 20 nM and 400 nM, respectively. Compounds are tested as 10-point IC50s, with a final DMSO concentration of 5%. Assay mixtures are incubated for 3 h prior to reading on the Fusion (ex 485 nm; em 535 nm). The data is fitted using a 4 parameter logistical data model by XLFit 4. The FP assay for Hsc70 and Grp78 is carried out as described for Hsp70 using the same N6 -(6-amino)hexyl-ATP-5-FAM as the FP probe with the following modiﬁcations. For Hsc70, the protein and probe concentrations are 0.3 μM and 20 nM, respectively with a 30 min incubation at 22℃ while for Grp78, the protein and probe concentrations are 2 μM and 10 nM, respectively with a 2 h incubation at 22℃. The KD for the FAM-ATP probe was 0.24 μM for Hsc70 and 2 μM for Grp78.

* 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 (g) = Concentration (mol/L) × Volume (L) × 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.
