Definitions

  • the invention relates to spirotricyclic derivatives, the process for their preparation, and their use as phosphodiesterase 7 (PDE7) inhibitors.
  • Phosphodiesterases play an important role in various biological processes by hydrolysing the key second messengers adenosine and guanosine 3′,5′-cyclic monophosphates (cAMP and cGMP respectively) into their corresponding 5′-monophosphate nucleotides. Therefore, inhibition of PDE activity produces an increase of cAMP and cGMP intracellular levels that activate specific protein phosphorylation pathways involved in a variety of functional responses.
  • At least eleven isoenzymes of mammalian cyclic nucleotide phosphodiesterases numbered PDE 1 through PDE 11, have been identified on the basis of primary structure, substrate specificity or sensitivity to cofactors or inhibitory drugs.
  • PDE7 is a cAMP-specific PDE.
  • PDE7 activity or protein has been detected in T-cell lines, B-cell lines, airway epithelial (AE) cell lines and several foetal tissues.
  • AE airway epithelial
  • AE cells actively participate in inflammatory airway diseases by liberating mediators such as arachidonate metabolites and cytokines.
  • mediators such as arachidonate metabolites and cytokines.
  • Selective inhibition of PDE7 may be a useful anti-inflammatory approach for treating AE cells related diseases.
