An orally available, long-acting inhibitor of phosphodiesterase (PDE) type 4 (PDE4), with anti-inflammatory and potential antineoplastic activities. Upon administration, roflumilast and its active metabolite roflumilast N-oxide selectively and competitively bind to and inhibit PDE4, which leads to an increase of both intracellular levels of cyclic-3′,5′-adenosine monophosphate (cAMP) and cAMP-mediated signaling. cAMP prevents phosphorylation of spleen tyrosine kinase (SYK) and abrogates activation of the PI3K/AKT/mTOR signaling pathway, which may result in the induction of apoptosis. PDE4, a member of the PDE superfamily that hydrolyses cAMP and 3′5′-cyclic guanosine monophosphate (cGMP) to their inactive 5′ monophosphates, is upregulated in a variety of cancers and may contribute to chemoresistance; it also plays a key role in inflammation, especially in inflammatory airway diseases. Check for active clinical trials or closed clinical trials using this agent.
