Product Description

ENMD-2076 (ENMD2076) is a novel,potent and orally bioactive inhibitor of multikinase including Aurora A and Flt3 with potential antitumor activity. It inhibits Aurora A and Flt3 with IC50s of 14 nM and 1.86 nM, respectively, and exhibits 25-fold selectivity for Aurora A over Aurora B. It shows potent in vitro antiproliferative activity and high in vivo antitumor efficacy.

Biological Activity I Assay Protocols (From Reference)
ln Vitro
ENMD-2076 is specific for Aurora A over Aurora B (IC50=350 nM). ENMD-2076 inhibits HUVEC proliferation at an IC50 of 0.15 mM. The IC50 values for 10 human leukemia cell lines range from 0.025 to 0.53 mM. In this panel, MV4:11 cells are the most responsive by a factor of more than 4. The lymphoma-derived U937 cell line treated with ENMD-2076 demonstrates a dose-dependent increase in G2-M-phase arrest and apoptosis. ENMD-2076 suppresses cellular Flt3 ligand (FL)-induced Flt3 autophosphorylation in THP-1 cells, which have been demonstrated to express FL-responsive wild-type Flt-3 (18), with an IC50 of 28 nM. ENMD-2076 inhibits stem cell factor (SCF)-induced Kit autophosphorylation in MO7e cells with an IC50 of 40 nM. ENMD-2076 inhibits VEGFR2/KDR autophosphorylation with an IC50 of 7 nM [1].
ln Vivo
Treatment with ENMD-2076 leads to statistically significant tumor growth or regression inhibition that is dose dependent. Furthermore, as fast-growing tumors like A375 melanoma and slow-growing tumors like HT29 colon carcinoma are similarly inhibited by ENMD-2076, there is no correlation between tumor growth rate and antitumor efficacy, which is theoretically expected for a mitotic kinase inhibitor. With the exception of the A375 model, studies have not found any weight loss or indications of morbidity at daily doses of up to 302 mg/kg (equivalent to 200 mg/kg of the free base) for ENMD-2076.
Animal Protocol
Dissolved in water or ENMD-2076 free base in CMC-Tween vehicle (0.075% carboxymethylcellulose, 0.085% Tween 80 in water); 300 mg/kg; Oral gavage
Tumor models including HCT-116, HT29, CT-26, A375, MDA-MB-231, H929, OPM-2, MV4;11 and HL60 are established in CB.17 SCID or NCr nude mice.

*Note: Please select an appropriate solvent for the preparation of stock solution based on your experiment needs. For most products, DMSO can be used for preparing stock solutions (e.g. 5 mM, 10 mM, or 20 mM concentration); some products with high aqueous solubility may be dissolved in water directly. Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.

Calculator

Molarity Calculator allows you to calculate the mass, volume, and/or concentration required for a solution, as detailed below:

  • Calculate the Mass of a compound required to prepare a solution of known volume and concentration
  • Calculate the Volume of solution required to dissolve a compound of known mass to a desired concentration
  • Calculate the Concentration of a solution resulting from a known mass of compound in a specific volume
An example of molarity calculation using the molarity calculator is shown below:
What is the mass of compound required to make a 10 mM stock solution in 5 ml of DMSO given that the molecular weight of the compound is 350.26 g/mol?
  • Enter 350.26 in the Molecular Weight (MW) box
  • Enter 10 in the Concentration box and choose the correct unit (mM)
  • Enter 5 in the Volume box and choose the correct unit (mL)
  • Click the “Calculate” button
  • The answer of 17.513 mg appears in the Mass box. In a similar way, you may calculate the volume and concentration.

Dilution Calculator allows you to calculate how to dilute a stock solution of known concentrations. For example, you may Enter C1, C2 & V2 to calculate V1, as detailed below:

What volume of a given 10 mM stock solution is required to make 25 ml of a 25 μM solution?
Using the equation C1V1 = C2V2, where C1=10 mM, C2=25 μM, V2=25 ml and V1 is the unknown:
  • Enter 10 into the Concentration (Start) box and choose the correct unit (mM)
  • Enter 25 into the Concentration (End) box and select the correct unit (mM)
  • Enter 25 into the Volume (End) box and choose the correct unit (mL)
  • Click the “Calculate” button
  • The answer of 62.5 μL (0.1 ml) appears in the Volume (Start) box
