p-ALK / ALK / p-AKT / AKT / p-ERK / ERK; 

PubMed: 28425916     

Inhibition of ALK autophosphorylation and downstream signaling by ceritinib, crizotinib and PF06463922 in NB-1 cells. Cells were harvested after treatment for 4 hr with the indicated compounds at different concentrations. Whole cell lysates were analyzed by Western blotting to detect the levels of ALK, AKT and ERK proteins and their phosphorylation.

pROS1 / ROS1 / pSTAT3 / STAT3 ; 

PubMed: 25351743     

Inhibition of phospho-ROS1 by various ALK inhibitors in Ba/F3 models. CD74-ROS1 expressing Ba/F3 cells were exposed to increasing concentrations of crizotinib, ceritinib, AP26113, or ASP3026 for 3 h. Cell lysates were immunoblotted to detect the indicated proteins.

Cell viability; 

PubMed: 29067644     

The effects of ceritinib treatment on cell viability in ARMS and ERMS cell lines. Cells were treated with 0-5 μM ceritinib for 72 h (Rh30, RD), 120 h (Rh41), or 144 h (Rh18, Aska) and cell viability was assessed. The y-axis represents relative cell viability compared to non-treated cells (control). Effects on cell viability were determined in triplicate. Values are presented as mean ± SD. Dotted line represents the IC50-value. The human synovial sarcoma cell line Aska with constitutive ALK phosphorylation was used as a positive control.

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]
- Collapse

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.

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.
