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.[1] 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.[2] VER-155008 causes a dose-dependent inhibition of cytokine-dependent AML cell proliferation.[3] VER-155008 shows an effective inhibition of cell proliferation in A549 and H1975 cells.

Protocol (from reference)

Kinase Assay:[1] [5]
  • 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.

Cell Research:[1]
  • Cell lines: BT474, MB-468, HCT116, and HT29 cells
  • Concentrations: 50 μM
  • Incubation Time: 72 h
  • Method: All cell lines are grown in DMEM/10% FCS with GlutaMAX-I in a humidified atmosphere of 5% CO2 in air. Cell proliferation is determined using the sulforhodamine B (SRB) assay.
Animal Research:[1]
  • Animal Models: HCT116 tumor bearing
  • Dosages: 40 mg/kg
  • Administration: i.v.

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.
