ALK4290
Based on 1 Customer Validation
ALK4290 (AKST4290) is a potent, orally active and selective CCR3 inhibitor with a Ki of 3.2 nM. ALK4290 blocks CCR3-mediated signaling, abrogates macrophage supernatant-driven mesothelial-to-mesenchymal transition, and decreases p38 phosphorylation. ALK4290 inhibits CCL26-CCR3 axis-driven GPX2-mediated B-cell activation, and targets B cells to inhibit activation by GPX2-overexpressing tumor cells. ALK4290 can be used for the research of hepatocellular carcinome and Parkinson’s disease.

Biological Activity
|
CCR3 3.2 nM (Ki) |
ALK4290 (5 µM; 1 h) abrogates macrophage-driven mesothelial-to-mesenchymal transition in human peritoneal mesothelial cells by inhibiting the CCR3/p38 MAPK pathway[1].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
-
Cell Line:human peritoneal mesothelial cells (HPMCs)
-
Concentration:5 µM
-
Incubation Time:1 h
-
Result:Abrogated the MMT-promoting effects of control macrophage-derived supernatant on HPMCs, reversing the reduction in E-cadherin protein expression and the increases in α-SMA, fibronectin (FN), and collagen I protein expression.
Blocked MMT in HPMCs exposed to HpMSCs-CM-treated macrophage-derived supernatant.
Decreased the phosphorylation level of p38 in HPMCs exposed to supernatant from THP1-derived macrophages treated with or without HpMSCs-CM.
Showed no significant effect on p-AKT/AKT or p-ERK/ERK ratios.

Solvent & Solubility
DMSO : 50 mg/mL (97.65 mM; ultrasonic and warming and heat to 60°C; 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: ≥ 2.5 mg/mL (4.88 mM); Clear solution
This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 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.
Add each solvent one by one: 10% DMSO 90% (20% SBE-β-CD in Saline)
Solubility: 2.5 mg/mL (4.88 mM); Suspended solution; Need ultrasonic
This protocol yields a suspended solution of 2.5 mg/mL. Suspended solution can be used for oral and intraperitoneal injection.
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 900 μL 20% SBE-β-CD in Saline, and mix evenly.
Preparation of 20% SBE-β-CD in Saline (4°C, storage for one week): 2 g SBE-β-CD powder is dissolved in 10 mL Saline, completely dissolve until clear.
