Application
Roflumilast N-Oxide: An Active Metabolite of Roflumilast, a Selective Phosphodiesterase 4 (PDE4) Inhibitor
Roflumilast N-oxide is an active metabolite of roflumilast [R0193] which is a selective phosphodiesterase 4 (PDE4) inhibitor. PDE4 is a key enzyme in the degradation of cyclic adenosine monophosphate (cyclic AMP) [A2381] and is centrally involved in the cytokine production of inflammatory cells. The inhibition of PDE4 activity leads to accumulation of intracellular cyclic AMP. Roflumilast N-oxide is also used for the treatment of chronic obstructive pulmonary disease (COPD). While the precise mechanism of the therapeutic action in COPD is not well defined, it is thought to be related to the effects of increased intracellular cyclic AMP in lung cells. (The product is for research purpose only.)
