|Description||Ceritinib (LDK378) is potent inhibitor against ALK with IC50 of 0.2 nM in cell-free assays. Ceritinib (LDK378) also inhibits IGF-1R, InsR, STK22D and FLT3 with IC50 of 8 nM, 7 nM, 23 nM and 60 nM, respectively. Phase 3.|
|Features||Does not cross react with c-Met, and has an improved in vivo glucose homeostasis profile relative to TAE684. May be active in Crizotinib-relapsed tumors.|
LDK378 shows great anti-proliferative activity in Ba/F3-NPM-ALK and Karpas290 cells with IC50 of 26.0 nM and 22.8 nM, compared with IC50 of 319.5 nM and 2477 nM in Ba/F3-Tel-InsR and Ba/F3-WT cells. 
|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. |
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)

* Please note that Selleck tests the solubility of all compounds in-house, and the actual solubility may differ slightly from published values. This is normal and is due to slight batch-to-batch variations.

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.
Calculate the mass, volume or concentration required for a solution. The Selleck molarity calculator is based on the following equation:
Mass (mg) = Concentration (mM) × Volume (mL) × Molecular Weight (g/mol)
*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).
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 )
* When preparing stock solutions always use the batch-specific molecular weight of the product found on the vial label and MSDS / COA (available online).

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.
