  • Quantitation of crystal violet uptake by ORF-expressing cells exposed to crizotinib (CRZ) or ceritinib (CER) normalized to Lac Z. Mean and SE are shown for six (CRZ) or four (CER) independent experiments of three replicates each.

    Cancer Cell, 2015, 27(3): 397-408 . Ceritinib (LDK378) purchased from Selleck.

    H3122 cells expressing pRS or shSMARCE1 vectors were cultured in the absence or presence of 100 nM NVP-TAE684, 400 nM Ceritinib, 1 μM gefitinib or their combination for 3 h. Cell lysates were harvested for immunoblot analysis and probed for the indicated proteins.

    Cell Res, 2015, 25(4): 445-58. Ceritinib (LDK378) purchased from Selleck.

  • (A) H3122 LDK_R show increased invasive and migratory capabilities compared to parental H3122, (B) loss of E-cadherin and increased mesenchymal markers including vimentin and AXL. Knockdown of vimentin decreased AXL expression in H3122 LDK_R.

In vivo LDK378 is designed to reduce the possibility of forming reactive metabolites and shows undetectable levels of glutathione (GSH) adducts (<1%) in liver microsomes. LDK378 has relatively good metabolic stability, with moderate CYP3A4 (Midazolam substrate) inhibition and hERG inhibition. LDK378 exhibits low plasma clearance in animals (mouse, rat, dog and monkey) compared to liver blood flow, with the oral bioavailability of above 55% in mouse, rat, dog and monkey. LDK378 induces a dose-dependent growth inhibition and tumor regression in the Karpas299 and H2228 rat xenograft models, with no body-weight loss. LDK378 shows no impact on insulin levels or plasma glucose utilization in the mouse upon chronic dosing up to 100 mg/kg. [1]


Kinase Assay:[1]

Enzymatic kinase profiling description:

All kinases are expressed as either Histidine- or GST-tagged fusion proteins using the baculovirus expression technology except for the untagged ERK2 which is produced in E. coli. The kinase activity is measured in the LabChip mobility shift assay. The assay is performed at 30°C for 60 min. The effect of LDK378 on the enzymatic activity is obtained from the linear progress curves in the absence and presence of LDK378 and routinely determines from one reading (end point measurement)

  • Cell lines: Ba/F3-NPM-ALK, Ba/F3-Tel-InsR, Ba/F3-WT, Karpas299 cells
  • Concentrations: ~100 μM
  • Incubation Time: 2-3 days
  • Method: Luciferase-expressing cells are incubated with serial dilutions of LDK378 or DMSO for 2-3 days. Luciferase expression is used as a measure of cell proliferation/survival and is evaluated with the Bright-Glo Luciferase Assay System. IC50 values are generated by using XLFit software.

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.
