Abstract

Abstract A PDE4B subtype selective inhibitor is expected to have a wider therapeutic window than non-selective PDE4 inhibitors. In this Letter, two series of 7, 8-dihydro-6H- thiopyrano [3, 2-d] pyrimidine derivatives and 5, 5-dioxo-7, 8-dihydro-6H-thiopyrano [3, 2-d] pyrimidine derivatives were evaluated for their PDE4B subtype selectivity using human PDE4B2 and PDE4D2 full length enzymes. To improve their PDE4B selectivity over ...
