Product Description

GNE-272 is a novel, potent and selective in vivo chemical probe for and inhibitor of the CBP/EP300 bromodomains with IC50 values of 0.02, 0.03 and 13 μM for CBP, EP300 and BRD4, respectively. The single bromodomain of the closely related transcriptional regulators CBP/EP300 is a target of much recent interest in cancer and immune system regulation. A co-crystal structure of a ligand-efficient screening hit and the CBP bromodomain guided initial design targeting the LPF shelf, ZA loop, and acetylated lysine binding regions. Structure-activity relationship studies allowed us to identify a more potent analogue. Optimization of permeability and microsomal stability and subsequent improvement of mouse hepatocyte stability afforded 59 (GNE-272, TR-FRET IC50 = 0.02 μM, BRET IC50 = 0.41 μM, BRD4(1) IC50 = 13 μM) that retained the best balance of cell potency, selectivity, and in vivo PK. GNE-272 showed a marked antiproliferative effect in hematologic cancer cell lines and modulates MYC expression in vivo that corresponds with antitumor activity in an AML tumor model.

Biological Activity I Assay Protocols (From Reference)
ln Vitro
GNE-272 is 650 times more selective than BRD4 and has good selectivity for CBP/EP300. Tested at 10 μM across 42 receptor and 35 kinase off-target screens, GNE-272 did not inhibit any target by more than thirty percent. Furthermore, GNE-272 does not inhibit several cytochrome P450s (3A4, 1A2, 2C9, 2C19, 2D6) at concentrations greater than 10 μM. The efficacy of this chemical in BRET cell tests is good. GNE-272 was found to decrease MYC10 (MV4-11 cell line) expression with an EC50 of 0.91 μM in an orthogonal assessment of target engagement, and there was a strong connection between BRET and MYC cell assays [1].
ln Vivo
GNE-272 had a good oral bioavailability of 26 μM when given at a dose of 100 mg/kg in mice PK tests, but showed limited clearance following an intravenous injection of 1 mg/kg. not in conjunction with Cmax. GNE-272 influences MYC expression in vivo and exhibits strong anti-proliferative effects in hematological cancer cell lines, both of which are indicative of anti-tumor efficacy in AML tumor models [1].

*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
