  • Ulixertinib inhibited the proliferation of SUDHL-10 and Raji cells. (A) The activation of ERK1/2 was analyzed by Western blotting. Ulixertinib (0.1, 0.4 and 1.0 nM) significantly inhibited ERK1/2 activation in a dose-dependent manner compared with control cells. Cell proliferation was measured by the CCK-8 assay. Ulixertinib (0.1, 0.4 and 1.0 nM) significantly inhibited proliferation of SUDHL-10 (B) and Raji cells (C) in a time- and dose-dependent manner compared with control cells.

Biological Activity

Description Ulixertinib (BVD-523, VRT752271) is a potent and reversible ERK1/ERK2 inhibitor with IC50 of <0.3 nM for ERK2. Phase 1.
Targets
ERK1 [1] ERK2 [1]
<0.3 nM
In vitro

In an A375 melanoma cell line containing a b-RAFV600E mutation, Ulixertinib reduces the levels of phosphorylated ERK2 (pERK) and of the phosphorylation of the downstream kinase RSK (pRSK) with IC50 of 4.1/0.14 μM, respectively. Ulixertinib also inhibits A375 cell proliferation with IC50 of 180 nM. [1]

ERK2 Rapidfire Mass Spectrometry Inhibition of Catalysis Assay:

MEK U911-activated ERK2 protein is expressed and purified in-house. Enzyme and substrate solutions are made up in assay buffer consisting of 50 mM Tris (pH 7.5), 10 mM MgCl2, 0.1 mM EGTA, 10 mM DTT and 0.01% (v/v) CHAPS. 1.2 nM ERK2 protein is prepared in assay buffer and 10 µL is dispensed into each well of a polypropylene, 384-well plate containing test and reference control compounds. The compound plates had previously been dosed with a 12 point range from 100 µM down to 0.1 nM in order to calculate compound IC50s, with a total DMSO concentration in the assay of 1%. Following a 20 minute pre-incubation of enzyme and compound at room temperature, 10 µL of substrate solution is added consisting of 16 µM Erktide (IPTTPITTTYFFFK) and 120 µM ATP (measured Km) in assay buffer. The reaction is allowed to progress for 20 minutes at room temperature before being quenched by the addition of 80 µl 1% (v/v) formic acid. The assay plates are then run on the RapidFire Mass Spectrometry platform to measure substrate (unphosphorylated Erktide) and product (phosphorylated Erktide) levels.

  • Cell lines: A375 cells
  • Concentrations: ~30 μM
  • Incubation Time: 72 h
  • Method: A375 cells are cultured in cell media composed of DMEM, 10% (v/v) Foetal Calf Serum and 1% (v/v) L-Glutamine. After harvesting, cells are dispensed into black, 384-well Costar plates to give 200 cells per well in a total volume of 40 µL cell media, and are incubated overnight at 37°C, 90% relative humidity and 5% CO2 in a rotating incubator. Test compounds and reference controls are dosed directly into the cell plates, into the inner 308 wells, using a Labcyte Echo 555 acoustic dispenser. The cells are dosed over a 12 point range from 30 µM down to 0.03 nM in order to calculate compound IC50s, with a total DMSO concentration in the assay of 0.3%. The cell plates are then incubated for 72 hours at 37°C. Cells were fixed and stained by the addition of 20 µL 12% formaldehyde in PBS/A (4% final concentration) and 1:2000 dilution of Hoechst 33342, with a 30 minute room temperature incubation, and then washed with PBS/A. A cell count is performed on the stained cell plates using a Cellomics ArrayScanTM VTI imaging platform. A Day 0 cell plate is also fixed, stained and read to generate a cell count baseline for determining compound cytotoxic effects as well as anti-proliferative effects.

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.
