  Synthesis and Structure-Activity Relationships of 6-Heterocyclic-Substituted Purines as Inactivation Modifiers of Cardiac Sodium Channels

  摘要：

  Purine-based analogs of SDZ 211-500 (5) were prepared and evaluated as inactivation modifiers of guinea pig or human cardiac sodium (Na) channels expressed in Xenopus oocytes. Substances which remove or slow the Na channel inactivation process in cardiac tissue are anticipated to prolong the effective refractory period and increase inotropy and thus have potential utility as antiarrhythmic agents. Heterocyclic substitution at the 6-position of the purine ring resulted in compounds with increased Na activity and potency, with 5-membered heterocycles being optimal. Only minor modifications to the benzhydrylpiperazine side chain were tolerated. Selected compounds which delayed the inactivation of Na channels were found to increase refractoriness and contractility in a rabbit Langendorff heart model, consistent with the cellular mechanism. Activity in both the oocyte and rabbit heart assays was specific to the S enantiomers. Preliminary in vivo activity has been demonstrated following intravenous infusion. The most promising compound on the basis of in vitro data is the formylpyrrole (S)-74, which is 25-fold more potent than DPI 201-106 (1) in the human heart Na channel assay.

  The Suzuki-Miyaura reaction of 9-unsubstituted 2-, 6-, and 8-halopurine bases with diverse aryl- and alkenylboronic acids in water-acetonitrile mixtures under microwave irradiation was used for the single-step synthesis of arylpurines. In most cases the product crystallized directly from the reaction mixture in high yields and good purity. The scope and limitations of these reactions were studied.

  通过水-乙腈混合物中微波辐照下，9-未取代的2-、6-和8-卤代嘌呤碱与多种芳基和烯基硼酸的Suzuki-Miyaura反应，实现了单步合成芳基嘌呤。在大多数情况下，产物以高产率直接从反应混合物中结晶，纯度良好。研究了这些反应的范围和局限性。
