A new series of thienopyrimidinones is synthesized and evaluated as selective phosphodiesterase 7 (PDE7) inhibitors for the treatment of inflammatory diseases. The modification of the substituents on thienopyrimidinone revealed that an isopropylamino group at the 2-position was favorable for aqueous solubility. The introduction of 3-pyrrolidines at the 7-position resulted in good solubility, highly potent activity, and good PDE7 selectivity. Among the synthesized compounds, compound 46 exhibited the greatest inhibition of ear edema in a phorbol ester-induced mouse model.
