  • PDE4

    PDE4B, IC50:130 nM
描述 cAMP is a fundamental second-messenger molecule produced in essentially all mammalian cells. 3′5′-Cyclic nucleotide phosphodiesterases (PDEs) are the enzymatic machinery that is responsible for the degradation of cAMP in cells by catalysing the hydrolysis of cAMP to 5′AMP. PDE4 family members specifically degrade cAMP, and they are expressed essentially in all immune cells including macrophages, neutrophils, eosinophils and lymphocytes, and in many other cell types, including epithelial cells, endothelium and fibroblasts. Rolipram is a selective inhibitor of phosphodiesterase PDE4, especially the PDE4B with IC50 of 130 nM and IC50 of 240 nM for PDE4D, with anti-inflammatory activity. Transient global cerebral ischemia in rats was induced by BCCAO. Rolipram at 0.3 mg/kg, but not 0.1 mg/kg, increased the time spent in the open arms and Discrimination index in the object location task, and the number of DCX-immunoreactive (DCX is a microtubule protein transiently expressed in both cytoplasm and dendrites of newborn neurons) neurons in BCCAO mice as compared to the BCCAO + veh group[3]. Bevacizumab (6.5 μg/ml) and rolipram (103 μM) individually led to the significant increase in the relative values of p53 and cleaved-caspase3 expressions in glioblastoma cancer stem-like cells (GCSCs) and the effect was strongly amplified when bevacizumab and rolipram were added to culture medium simultaneously[4]. Rolipram inhibited LPS-induced TNF production and TNF mRNA levelsin a dose-dependent manner (IC50 25.9 nM) in J774 mouse macrophages, which was mediated by MAPK phosphatase-1 (MKP-1)[5].
