生物活性

PF-04957325 is a highly potent and selective PDE8 inhibitor, with IC50s of 0.7 nM and 0.3 nM for PDE8A and PDE8B, respectively.

IC50 & Target

IC50: 0.7 nM (PDE8A), less than 0.3 nM (PDE8B)[1]

体外研究
(In Vitro)

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].

Cell Assay
[2]

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].
