  描述：

  5-acetyl-2-ethyl-4-nitro-6-phenylpyridazin-3(2H)-one 在 sodium ethanolate 作用下， 以 乙醇 为溶剂， 反应 0.83h， 生成 ethyl 6-ethyl-3-methyl-7-oxo-4-phenyl-1H-pyrrolo[2,3-d]pyridazine-2-carboxylate

  名称：

  Novel Heterocyclic-Fused Pyridazinones as Potent and Selective Phosphodiesterase IV Inhibitors

  摘要：

  A series of 6-aryl-4,5-heterocyclic-fused pyridazinones were designed and synthesized as selective phosphodiesterase (PDE) TV inhibitors. Biological evaluation of these compounds demonstrated a good selectivity profile toward the PDE TV family and greatly attenuated affinity for the Rolipram high-affinity binding site that seems to be responsible for undesiderable side effects. Structure-activity relationships (SARs) studies showed that the presence of an ethyl group at pyridazine N-2 is associated with the best potency and selectivity profile.
