Biological Activity

Description GSK620 is a pan-BD2 inhibitor, which shows an anti-inflammatory phenotype in human whole blood with excellent broad selectivity, developability, and in vivo oral pharmacokinetics.
Targets
BD2 [1]
()
In vitro

GSK620 is highly selective for the BET-BD2 family of proteins, with >200-fold selectivity over all other bromodomains. GSK620 is capable of reducing the MCP-1 response in a concentration-dependent manner, providing strong evidence that GSK620 is indeed engaging BD2 in cells.[1]

In vivo

GSK620 is a potent and selective pan-BD2 inhibitor with excellent in vivo PK properties and excellent developability properties, with the exception of moderate FaSSIF solubility driven by its highly crystalline nature.[1]

Protocol (from reference)

Cell Research:

[1]

  • Cell lines: human whole blood, hepatocytes
  • Concentrations: 0.5 μM
  • Incubation Time: 60 min, 120 min
  • Method:

    GSK620 is diluted in 100% DMSO to give a range of appropriate concentrations at 140× the required final assay concentration, of which 1 μL is added to a 96 well tissue culture plate. Then 130 μL of human whole blood, collected into sodium heparin anticoagulant (1 unit/mL final) is added to each well and plates are incubated at 37℃ (5% CO2) for 30 min before the addition of 10 μL of 2.8 μg/mL LPS, diluted in complete RPMI 1640 (final concentration 200 ng/mL), to give a total volume of 140 μL per well. After further incubation for 24 h at 37℃, 140 μL of PBS is added to each well. The plates are sealed, shaken for 10 min, and then centrifuged (2500 rpm × 10 min). Finally, 100 μL of the supernatant is removed and MCP-1 levels assayed immediately by immunoassay.

Animal Research:

  • Animal Models: Male Wistar Han rats, male Beagle dog
  • Dosages: 0.5 mg/kg, 1 mg/kg, 3 mg/kg

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.
