PF-719
PF-719 is a highly selective Pyk2 inhibitor with an IC50 value of 17 nM. PF-719 promotes the activation of LKB1 and p38 MAPK. PF-719 blocks synaptic deficits induced by Amyloid-beta oligomers and reverses the inhibition of long-term potentiation induced by β-amyloid oligomers. PF-719 can be used in research related to Alzheimer's disease and autoimmune diseases.

Biological Activity
PF-719 (2 h) inhibits the activity of Pyk2 and significantly increases the phosphorylation levels of Tau at the S396/S404 and S202/T205 sites in mature iPSC-derived cortical neurons, without altering the activity of GSK3β[1].
Pretreatment of acute hippocampal slices from wild-type mice with PF-719 (500 nM; 30 min) completely reverses the β-amyloid oligomer-induced inhibition of long-term potentiation[2].
PF-719 is a highly selective inhibitor of purified Pyk2 kinase in vitro, with an IC50 value of 17 nM[3].
PF-719 (1 μM; 1 h pre-incubation, 3 h chemokinesis assay) inhibits CXCL13-induced chemotaxis of primary mouse splenic B-2 cells and marginal zone (MZ) B cells, as well as S1P-induced chemotaxis of MZ B cells at a concentration of 1 μM[3].
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: ≥ 2.08 mg/mL (4.64 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.
Add each solvent one by one: 10% DMSO 90% (20% SBE-β-CD in Saline)
Solubility: ≥ 2.08 mg/mL (4.64 mM); Clear solution
This protocol yields a clear solution of ≥ 2.08 mg/mL (saturation unknown).
