Ceritinib diHCl (LDK-378; LDK378; Zykadia; Spexib), the dihydrochloride salt of ceritinib, is an ALK (anaplastic lymphoma kinase positive) inhibitor approved in 2014 for the treatment of non-small cell lung cancer (NSCLC).
Targets |
ALK (IC50 = 0.2 nM); IGF-1R (IC50 = 8 nM); InsR (IC50 = 7 nM); STK22D (IC50 = 23 nM)

Enzyme Assay |
All kinases are expressed using the baculovirus expression technology as either GST- or histidine-tagged fusion proteins, with the exception of untagged ERK2, which is made in E. coli. Using the LabChip mobility shift assay, the kinase activity is determined. For sixty minutes, the assay is run at 30°C. LDK378's impact on enzymatic activity is typically determined from a single reading (end point measurement), which is derived from the linear progress curves in both the presence and absence of LDK378.

|
Cell Assay |
LDK378 or DMSO are serially diluted and incubated with luciferase-expressing cells for two to three days. Using the Bright-Glo Luciferase Assay System, luciferase expression is measured as a proxy for cell proliferation and survival. The XLFit program is used to generate IC50 values.

Solubility (In Vivo) |
Solubility in Formulation 1: 2.5 mg/mL (3.96 mM) in 10% DMSO + 40% PEG300 + 5% Tween80 + 45% Saline (add these co-solvents sequentially from left to right, and one by one), clear solution; with sonication.
For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 25.0 mg/mL clear DMSO stock solution to 400 μL PEG300 and mix evenly; then add 50 μL Tween-80 to the above solution and mix evenly; then add 450 μL normal saline to adjust the volume to 1 mL. Preparation of saline: Dissolve 0.9 g of sodium chloride in 100 mL ddH₂ O to obtain a clear solution. Solubility in Formulation 2: ≥ 2.5 mg/mL (3.96 mM) (saturation unknown) in 10% DMSO + 90% (20% SBE-β-CD in Saline) (add these co-solvents sequentially from left to right, and one by one), clear solution. For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 25.0 mg/mL clear DMSO stock solution to 900 μL of 20% SBE-β-CD physiological saline solution and mix evenly. Preparation of 20% SBE-β-CD in Saline (4°C,1 week): Dissolve 2 g SBE-β-CD in 10 mL saline to obtain a clear solution. View More
Solubility in Formulation 3: ≥ 2.5 mg/mL (3.96 mM) (saturation unknown) in 10% DMSO + 90% Corn Oil (add these co-solvents sequentially from left to right, and one by one), clear solution. Solubility in Formulation 4: 33.33 mg/mL (52.82 mM) in PBS (add these co-solvents sequentially from left to right, and one by one), clear solution; with ultrasonication. |

*Note: Please select an appropriate solvent for the preparation of stock solution based on your experiment needs. For most products, DMSO can be used for preparing stock solutions (e.g. 5 mM, 10 mM, or 20 mM concentration); some products with high aqueous solubility may be dissolved in water directly. Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.
Calculation results
Working concentration: mg/mL;
Method for preparing DMSO stock solution: mg drug pre-dissolved in μL DMSO (stock solution concentration mg/mL). Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug.
Method for preparing in vivo formulation::Take μL DMSO stock solution, next add μL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O,mix and clarify.
(1) Please be sure that the solution is clear before the addition of next solvent. Dissolution methods like vortex, ultrasound or warming and heat may be used to aid dissolving.
(2) Be sure to add the solvent(s) in order.
