产品描述 Description

PF-04957325 is a kind of highly potent PDE8-selective inhibitor and the values of IC50 for PDE8A and PDE8B are 0.7nM and 0.3nM, respectively [1].

PF-04957325 (0.1, 1μM; 45min) inhibited T cell adhere to endothelial cells [2]. PF-04957325 (0.01 ~1000nM) increased concentrations of cAMP in a concentration-dependent manner in HASM cells [3].

PF-04957325 (0.1, 1mg/kg; 21d; i.g.) downregulated the expression levels of IL-1β, IL-6 and COX-2 in AβO-induced alzheimer’s disease (AD) C57BL/6J mice; PF-04957325 (1mg/kg; 21d; i.g.) increased the expression of CD206 and Arg-1 with a significant effect in AβO-induced AD C57BL/6J mice [4]. PF-04957325 (10mg/kg; 4d; bid; s.c.) showed significant reductions in the number of infiltrates in the brain meninges and spinal cord in experimental autoimmune encephalomyelitis (EAE) C57BL/6 mice [5].

PF-04957325是一种高效的PDE8选择性抑制剂，其抑制PDE8A和PDE8B的IC50分别为0.7nM和0.3nM[1]。

PF-04957325（0.1和1μM；45min）可以抑制T细胞与内皮细胞的黏附[2]。PF-04957325（0.01 ~1000nM）以浓度依赖的方式增加HASM细胞内的cAMP浓度[3]。

PF-04957325（0.1、1mg/kg；21d；i.g.）下调了由AβO引发的阿尔茨海默症C57BL/6J小鼠模型体内IL-1β、IL-6和COX-2的表达水平；PF-04957325（1mg/kg；21d；i.g.）对增加由AβO引发的阿尔茨海默症C57BL/6J小鼠模型的CD206和Arg-1的表达有显著作用[4]。PF-04957325（1mg/kg；4d；bid；s.c.）显著减少了实验性自身免疫性脑脊髓炎C57BL/6小鼠模型的脑膜和脊髓中的浸润物数量[5]。

实验参考方法 Experimental Reference Method

Cell experiment [1]:

Cell lines

Murine brain endothelium-derived cell line bEnd.3

Preparation Method

PF-04957325 was added to bEnd.3 cells for the last 45min of incubation. T cell blasts or Teff cells were labeled with Calcein AM and then were incubated on bEnd.3 cells. Calcein AM labeled T cell blasts or Teff cells were used as positive controls.

Reaction Conditions

0.1 and 1μM; 45min

Applications

PF-04957325 suppressed T cell adhesion to endothelial cells.
Animal experiment [2]:

Animal models

Male C57BL/6J mice

Preparation Method

The alzheimer’s disease (AD) mouse models were established by microinjecting AβO into the hippocampus. The mice were administered by gavage with PF-04957325 at the dose of 0.1 or 1mg/kg or its vehicle for consecutive 21d after 3d of AβO stimulation. The inflammatory factors were determined using Mouse Quantikine ELISA kits.

Dosage form

0.1, 1mg/kg; 21d; i.g.

Applications

PF-04957325 downregulated the expression levels of IL-1β, IL-6, and COX-2 in AβO-induced AD model mice.
