Biological Activity
IC50: 0.7 nM (PDE8A), less than 0.3 nM (PDE8B)[1]
PF-04957325 is over two orders of magnitude less efficient than PICL in suppressing polyclonal Teff cell proliferation, and shows no effect on cytokine gene expression in these cells, despite its robust effect on T cell adhesion[1]. PF-04957325 is a selective PDE8 inhibitor and inhibits breast cancer cell migration[2]. PF-04957325 greatly potentiates steroidogenesis in WT adrenal cells. PF-04957325 shows a reported IC50 of 0.7 nM against PDE8A, 0.2 nM against PDE8B, and > 1.5 μM against all other PDE isoforms[3]. PF-04957325 treatment of WT Leydig cells or MA10 cells increases steroid production but has no effect in PDE8A (-/-)/B(-/-) double-knockout cells, confirming the selectivity of the drug. Moreover, under basal conditions, cotreatment with PF-04957325 plus rolipram, a PDE4-selective inhibitor, synergistically potentiates steroid production[4].

Solvent & Solubility
DMSO : ≥ 100 mg/mL (249.76 mM; Hygroscopic DMSO has a significant impact on the solubility of product, please use newly opened DMSO)
* "≥" means soluble, but saturation unknown.
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, 2 years; -20°C, 1 year. When stored at -80°C, please use it within 2 years. When stored at -20°C, please use it within 1 year.

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 (6.24 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 (6.24 mM); Clear solution

Protocol
Breast cancer cells are in a total volume of 0.1 mL of fresh medium containing the test reagents or vehicle (PF-04957325). Following incubation at 37°C for 72 h, 20 μL of a combined solution of MTS (2 mg/mL)/PMS (0.92 mg/mL) (20:1, mixed immediately before use) is added to each well, and the plates incubated for an additional 2 h at 37°C, protected from light, following which the absorbency of the formazan product formed is determined at 492 nm using a microtiter plate reader. All reagents tested are dissolved in DMSO and diluted into the cell culture medium[2].
