MAZ51
Based on 8 publication(s) in Google Scholar
MAZ51 is a selective inhibitor of VEGFR-3 (Flt-4) tyrosine kinase. MAZ51 inhibits VEGF-C-induced activation of VEGFR-3 without blocking VEGF-C-mediated stimulation of VEGFR2. MAZ51 had no effect on ligand-induced autophosphorylation of EGFR, IGF-1R and PDGFRβ. MAZ51 blocks proliferation and induces apoptosis in a wide variety of tumor cells. Antitumor activity.

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 90% (20% SBE-β-CD in Saline)
Solubility: ≥ 0.83 mg/mL (2.64 mM); Clear solution
This protocol yields a clear solution of ≥ 0.83 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (8.3 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.
For the following dissolution methods, please prepare the working solution directly:
