Tetracyclic guanines have been shown to be potent and selective inhibitors of the cGMP-hydrolyzing enzymes PDE1 and PDE5. In general, these compounds are inactive or only weakly active as inhibitors of PDE3, which is a major isozyme involved in cAMP

The synthesis and CETP inhibitory activity of a series of compounds related to wiedendiols ( 1a,1b ) are reported. It is proposed that a two point pharmacophore consisting of a catechol group and a large hydrophobic anchor is necessary for activity.
