Roflupram (FFPM) is a potent anti-inflammatory phosphodiesterase 4 (PDE4) inhibitor that was found to suppress inflammasome activation in microglial cells by enhancing autophagy. In microglial BV-2 cells roflupram enhanced the level of microtubule-associated protein 1 light chain 3 II (LC3-II) and decreased the autophagy receptor ubiquitin-binding protein p62 (SQSTM1), enhancing autophagy, reducing the activation of inflammasome and suppressing the production of IL-1β. Roflupram (FFPM) was found to reverse learning and memory deficits in APP/PS1 transgenic mice.

Inhibition of phosphodiesterase 4 (PDE4) suppressed the inflammatory responses in the brain. However, the underlying mechanisms are poorly understood. Roflupram (ROF) is a novel PDE4 inhibitor. In the present study, we found that ROF enhanced the level of microtubule-associated protein

Phosphodiesterase 4 catalyzes the hydrolysis of cyclic AMP and is a target for the development of anti-inflammatory agents. We have designed and synthesized a series of phenyl alkyl ketones as PDE4 inhibitors. Among them, 13 compounds were identified as having

In the present study, we investigated the effect of classic PDE4 inhibitor rolipram and novel PDE4 inhibitor ZL-n-91 on LPS-induced acute lung injury (ALI) in mice and its mechanism. ALI was induced in ICR mice by instilling intratracheally with LPS
Thus far, phosphodiesterase-4 (PDE4) inhibitors have not been approved for application in Alzheimer's disease (AD) in a clinical setting due to severe side effects, such as nausea and vomiting. In this study, we investigated the effect of FFPM, a novel
International immunopharmacology, 90, 107176-107176 (2020-11-28)
Roflupram (ROF) is a novel phosphodiesterase 4 inhibitor. We previously found that ROF suppressed the production of pro-inflammatory factors in microglial cells; however, the underlying mechanisms are largely unknown. The present study aimed to elucidate the underlying molecular mechanisms of
