A series of novel thienopyrimidin-4-amines have been synthesized and evaluated as phosphodiesterase (PDE) inhibitors. A rationale for the observed selectivity against PDE7 has been obtained from molecular modelling studies on the most active compounds. This journal is the Partner Organisations 2014.
