  • ERK1/2 inhibition reverse EMT in H1299- EML4-ALK cells. H1299-EML4-ALK cells were treated with FR180204 (10 μM), crizotinib (10 nM) and S3I-201(20 μM) for 24 h, cell extracts were analyzed by immunoblotting.

    Biochem Biophys Res Commun, 2015, 459(3): 398-404. FR 180204 purchased from Selleck.

In vitro

In AP-1-transfected cells, FR180204 dose-dependently inhibits AP-1 transactivation with IC50 of 3.1 μM. [1] FR 180204 inhibits spontaneous mesothelioma cell growth. [3]

In vivo In collagen-induced arthritis mice, FR180204 (100 mg/kg, i.p., b.i.d.) significantly decreases the severity of symptoms and body weight loss. [2] In a mouse model of dengue virus (DENV) infection, FR180204 limits hepatocyte apoptosis, reduces DENV-induced liver injury, and improves Clinical parameters. [4]


Kinase Assay:[1]

ERK assay:

Nunc-Immuno MaxiSorp plates are coated with 20 μg/ml MBP solution in phosphate-buffered saline (PBS). After washing with PBS containing 0.05% Tween 20 (T-PBS), blocking buffer (T-PBS containing 3% BSA) is added to each well and the plates are incubated for 10 min at room temperature. After washing with T-PBS, chemical compounds, ATP and recombinant ERK2 diluted in assay dilution buffer (20 mM Mops, pH 7.2, 25 mM β-glycerol phosphate, 5 mM EGTA, 1 mM sodium orthovanadate, 1 mM dithiothreitol, and 50 μg/ml BSA) and are added to each well. Vehicle groups (containing 0.1% DMSO) and kinase-withdrawal groups are used for the control and basal determinations. After incubation for 1 h at room temperature, plates are washed twice with T-PBS. Anti-phospho MBP antibody (0.2 μg/ml) is added to each well, and the plates are incubated for 1 h at room temperature. After washing, anti-mouse HRP-conjugated polyclonal antibodies are added and the plates were incubated for 30 min. SuperSignal chemiluminescent substrate is used for the measurement of HRP activity according to the manufacturer’s instructions. Prism 4.0 software is used for the Lineweaver–Burk plot analysis, IC50 and Ki determinations.

*When preparing stock solutions, please always use the batch-specific molecular weight of the product found on the via label and MSDS / COA (available on product pages).

Dilution Calculator

Dilution Calculator

Calculate the dilution required to prepare a stock solution. The Selleck dilution calculator is based on the following equation:

Concentration (start) x Volume (start) = Concentration (final) x Volume (final)

This equation is commonly abbreviated as: C1V1 = C2V2 ( Input Output )

Definitions of molecular mass, molecular weight, molar mass and molar weight:

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.
