Abstract

The synthesis and the biological evaluation of new potent phosphodiesterase type 4 (PDE4) inhibitors are presented. This new series was elaborated by replacement of the metabolically resistant phenyl hexafluorocarbinol of L-791,943 (1) by a substituted aminopyridine residue. The structure–activity relationship of N-substitution on 3 led to the identification of (−)-3n which exhibited a good PDE4 inhibitor activity (HWB-TNFα= 0.12 ...
