Biological Activity

Description VER-49009 (CCT0129397) is a potent HSP90 inhibitor with IC50 of 47 nM for HSP90β.
HSP90β [1]
47 nM
In vitro

VER-49009 inhibits the intrinsic ATPase activity of recombinant yeast Hsp90 with IC50 of 167 nM, and produces antiproliferative activity in a panel of human cancer cell lines and nontumorigenic cells in vitro. VER-49009 causes induction of HSP72 and HSP27 with depletion of client proteins, including C-RAF, B-RAF, and survivin, and PRMT5, which further result in cell cycle arrest and apoptosis. [1] VER-49009 inhibits the cell proliferation, and induces G2 phase arrest in hepatic stellate cell line CFSC cells, which may suggest a rational approach in the prevention of liver fibrosis. [2]

In vivo In athymic mice, VER-49009 (20 mg/kg, i.v.) shows rapid clearance with values of 0.187 L/h. In an orthotopic human ovarian carcinoma model, VER-49009 (4 mg/kg, i.p.) also induces the depletion of the sensitive HSP90 client protein ERBB2. [1]

Protocol (from reference)

Kinase Assay:


  • Fluorescence Polarization Assay:

    Binding of HSP90 inhibitors to human full-length recombinant HSP90β is determined by a competitive binding fluorescence polarization assay, using a fluorescent pyrazole resorcinol probe.

Cell Research:


  • Cell lines: Melanoma cells (SKMEL 2, SKMEL 5, SKMEL 28, WM266.4); Colon cancer cells (HCT116, BEneg, BE2, HT29, HT29oxaliR); Ovarian cancer cells (CH1, CH1doxR); Breast cancer cells (MB-231, MB-468, BT20, ZR751, MCF7, BT-474); nontumorigenic cells (HUVEC, MCF10a, PNT
  • Concentrations: ~10 μM
  • Incubation Time: 4 days
  • Method:

    Antiproliferative effects are measured using the sulforhodamine B assay. HUVEC sensitivity is determined by an alkaline phosphatase method.

Animal Research:


  • Animal Models: Mice bearing established OVCAR3 human ovarian xenografts.
  • Dosages: ~4 mg/kg
  • Administration: i.p.

Method for preparing DMSO master liquid: mg drug pre-dissolved in μL DMSO ( Master liquid concentration mg/mL, Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug. )

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.
