  Inhibition of cyclic adenosine-3',5'-monophosphate phosphodiesterase from vascular smooth muscle by rolipram analogs

  摘要：

  Rolipram [(R,S)-4-[3-(cyclopentyloxy)-4-methoxyphenyl]-2-pyrrolidone] has been shown to inhibit selectively the cAMP phosphodiesterase (PDE) of vascular smooth muscle. In order to further explore the structural requirements for selective PDE inhibition, we synthesized a series of rolipram derivatives differently substituted either at the pyrrolidinone or at the aromatic ring. Among these compounds, rolipram was the most active compound. Semirigid analogues were prepared and used for an evaluation of the active conformation of rolipram. Structural comparison with two other potent and chemically different smooth muscle cAMP-PDE inhibitors, trequinsin and Ro 20-1724, allows us to propose a first topological model of the smooth muscle cAMP-PDE pharmacophore.

  The present invention is directed to a method for reducing the emetogenic effects of PDE inhibitors, and more particularly is directed to compounds having PDE4 inhibition activity with little or no emetogenic side-effects, and chemical methods including benzylation for preparing such compounds. A benzyl group may be attached to either a carbon or nitrogen atom of a PDE4 inhibitor. Suitable benzylation chemistry is to extract a hydrogen from a PDE4 inhibitor, preferably with a base, and then react the resulting nucleophilic PDE4 inhibitor with a benzylating agent, e.g., benzyl bromide or a derivative thereof.
