Biological Activity

Description GSK2879552 2HCl is a potent, selective, orally bioavailable, irreversible LSD1 inhibitor with Kiapp of 1.7 μM. Phase 1.
LSD1 [1]
(Cell-free assay)
1.7 μM(Ki)
In vitro

In 165 cell lines, GSK2879552 inhibits the growth of 9/28 small cell lung carcinoma (SCLC) lines and 20/29 AML lines ranged from 40% to 100%. The subset of SCLC lines and primary samples that undergo growth inhibition in response to GSK2879552 exhibit DNA hypomethylation of a signature set of probes. [1]

Protocol (from reference)

Kinase Assay:[1]
  • LSD1 enzyme assay:

    LSD1 activity was measured using a horseradish peroxidase (HRP) coupled assay with amplex red as an electron donor. The formation of product over time is measured using fluorescence intensity, Ex 531 nm and Em 595 nm, in a PerkinElmer EnVision plate reader. Final assay conditions are: 5 nM LSD1, 2.5 μM H3K4me2 peptide, 50 mM HEPES pH 7, 1 U/ml of HRP, 1 mM CHAPS, 0.03% dBSA and 10 μM amplex red.

Cell Research:[1]
  • Cell lines: 165 human cancer cell lines
  • Concentrations: ~10 μM
  • Incubation Time: 6 d
  • Method: The optimal cell seeding is determined empirically for all cell lines by examining the growth of a wide range of seeding densities in a 384-well format to identify conditions that permitted proliferation for 6 days. Cells are then plated at the optimal seeding density 24 h before treatment (in duplicate) with a 20-point twofold dilution series of GSK2879552 or 0.15% DMSO. Plates are incubated for 6 days at 37°C in 5% CO2. Cells are then lysed with CellTiter-Glo (CTG) (Promega) and chemiluminescent signal is detected with a TECAN Safire2 microplate reader. In addition, an untreated plate of cells is harvested at the time of compound addition (T0) to quantify the starting number of cells. CTG values obtained after the 6 day treatment are expressed as a percent of the T0 value and plotted against compound concentration. Data are fit with a four-parameter equation to generate a concentration response curve and the concentration of GSK126 required to inhibit 50% of growth (growth IC50) is determined.

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.
