WRG-28
Based on 3 publication(s) in Google Scholar
WRG-28 is a selective, extracellularly acting DDR2 allosteric inhibitor, with an IC50 of 230 nM. WRG-28 inhibits tumor invasion, migration and tumor-supporting effects of cancer-associated fibroblasts (CAFs). WRG-28 inhibits metastatic breast tumor cell colonization in the lungs. WRG-28 also shows good activity of relieving rheumatoid arthritis in CAIA model of mice.

DDR2 230 nM (IC50) |
WRG-28 (1, 2 μM; 4 h) blunts collagen I-mediated DDR2 tyrosine phosphorylation and (1 μM; 7 h) ERK activation as well as SNAIL1 protein stabilization in HEK293 cells (expressing DDR2) (IC50=286 nM)[1].
WRG-28 (1 μM; 48 h) blunts tumor cell invasion and migration by inhibiting DDR2 in BT549 and 4T1 breast cancer cells[1].
WRG-28 (1 μM; 4 days) inhibits tumor-promoting effects of CAFs[1].
WRG-28 (0.5, 1 μM; 4 h) maintains inhibitory action toward acquired DDR2 mutations that are resistant to TKIs[1].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

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: ≥ 1 mg/mL (2.44 mM); Clear solution
This protocol yields a clear solution of ≥ 1 mg/mL (saturation unknown).
