DS12881479
Based on 1 publication(s) in Google Scholar
DS12881479 is a selective non-ATP-competitive MNK1 inhibitor with an IC50 value of 387 nM. DS12881479 stabilizes MNK1 in its autoinhibited DFD-out conformation, blocks eIF4E phosphorylation, suppresses tumor cell proliferation and induces weak apoptosis. DS12881479 also inhibits FLT3 and DYRK1a kinase activity at high concentrations. DS12881479 can be used for the research of cancer, such as leukemia.

DS12881479 (72-120 h) inhibits proliferation of MV4-11, MOLM-13, and MM.1S cancer cells with IC50 values of 3.32 ± 0.66 μM, 12.08 ± 0.92 μM, and 5.32 ± 1.38 μM, respectively, and lacks activity against MDA-MB-231 cells (IC50 >20 μM)[1].
DS12881479 (300-1000 nM; 24 h) inhibits eIF4E phosphorylation in MV4-11 cells without degrading MNK1 or MNK2 protein[1].
DS12881479 (300 nM; 24 h) weakly induces apoptosis in MV4-11 cells, with a total apoptotic rate of 13.9%[1].
DS12881479 potently inhibits inactive human Mnk1 with an IC50 of 21 nM, and shows weaker inhibition of active human Mnk1 with an IC50 of 416 nM[2].
DS12881479 (5 μM) inhibits only FLT3 and DYRK1a by over 50%, demonstrating good selectivity for human Mnk1 over most other tested active kinases[2].

Solvent & Solubility
DMSO : 250 mg/mL (829.43 mM; Need ultrasonic; Hygroscopic DMSO has a significant impact on the solubility of product, please use newly opened DMSO)
Please refer to the solubility information to select the appropriate solvent. Once prepared, please aliquot and store the solution to prevent product inactivation from repeated freeze-thaw cycles.
Storage method and period of stock solution: -80°C, 6 months; -20°C, 1 month. When stored at -80°C, please use it within 6 months. When stored at -20°C, please use it within 1 month.

Select the appropriate dissolution method based on your experimental animal and administration route.
- For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
- To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for In Vivo experiments, it is recommended to prepare freshly and use it on the same day.
- The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.
Add each solvent one by one: 10% DMSO 40% PEG300 5% Tween-80 45% Saline
Solubility: ≥ 2.08 mg/mL (6.90 mM); Clear solution
This protocol yields a clear solution of ≥ 2.08 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (20.8 mg/mL) to 400 μL PEG300, and mix evenly; then add 50 μL Tween-80 and mix evenly; then add 450 μL Saline to adjust the volume to 1 mL.
Preparation of Saline: Dissolve 0.9 g sodium chloride in ddH₂O and dilute to 100 mL to obtain a clear Saline solution.
Please enter the basic information of animal experiments:

Recommended: Prepare an additional quantity of animals to account for potential losses during experiments.
Please enter your animal formula composition:

The co-solvents required include: DMSO, . All of co-solvents are available by MedChemExpress (MCE). , Tween 80. All of co-solvents are available by MedChemExpress (MCE).
Working solution concentration: 0.22 mg/mL
Method for preparing stock solution: mg drug dissolved in μL DMSO. Stock solution concentration: mg/mL.
1. Take μL DMSO stock solution;
2. Add μL .
μL , mix evenly;
3. Then add μL Tween 80, mix evenly;
4. Then add μL
Please ensure that the stock solution in the first step is dissolved to a clear state, and add co-solvents in sequence. You can use ultrasonic heating (ultrasonic cleaner, recommended frequency 20-40 kHz), vortexing, etc. to assist dissolution.
