  Selective Inhibitors of Cyclic AMP-Specific Phosphodiesterase:  Heterocycle-Condensed Purines

  摘要：

  To reverse the adverse reactions of alkylxanthines and to develop novel inhibitors of cyclic AMP-specific phosphodiesterase (PDE IV), a series of heterocycle-condensed purines were designed and synthesized. Some of these new compounds had similar or more potent and selective inhibitory activity against PDE IV than known PDE IV inhibitors. The tracheal-relaxant activity of these compounds was closely correlated with their PDE IV-inhibitory activity. Moreover, these purine analogues did not have any positive-chronotropic action or adenosine-antagonistic action on isolated heart preparations, which are the particular adverse reactions of alkylxanthines. Among them, 3,4-dipropyl-4,5,7,8-tetrahydro-3H-imidazo[1,2-i]purin-5-one (1c), which was the most selective and potent PDE TV inhibitor, did not cause emesis in Suncus murinus at a dosage range of 10-100 mg/kg (po), while an imidazole analogue of 1c (4c) and known PDE IV inhibitors such as rolipram and denbufylline caused emesis even at 10 or 30 mg/kg.
