Biological Activity

Description VER-50589 is a potent HSP90 inhibitor with IC50 of 21 nM for HSP90β.
HSP90β [1]
21 nM
In vitro

VER-50589 inhibits the intrinsic ATPase activity of recombinant yeast Hsp90 with IC50 of 143 nM, and produces antiproliferative activity in a panel of human cancer cell lines and nontumorigenic cells in vitro. VER-50589 causes induction of HSP72 and HSP27 alongside depletion of client proteins, including C-RAF, B-RAF, and survivin, and the protein arginine methyltransferase PRMT5, which further result in cell cycle arrest and apoptosis. [1]

In vivo In HCT116 human colon cancer xenografts, VER-50589 (100 mg/kg i.p.) results in a statistically significant reduction of ∼30% in tumor volume and weight, as well as induction of HSP72 and depletion of ERBB2 and C-RAF. [1]

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 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.

Bio Calculators

Molarity Calculator

Molarity Calculator

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)

  • Mass
    Molecular Weight

*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).

Dilution Calculator

Dilution Calculator

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 )

  • C1

* 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.
