Synthesis and biological activities of 1-pyridylisoquinoline and 1-pyridyldihydroisoquinoline derivatives as PDE4 inhibitors

A novel series of 1-pyridylisoquinoline and 1-pyridyldihydroisoquinoline derivatives has been prepared. These compounds showed potent PDE4 inhibitory activities and a broad margin between the Ki value of the rolipram binding affinity and the IC50 value of PDE4 inhibition. They also exhibited potent inhibitory activities toward LPS-induced TNF-α production in mice.
