  A Series of Ligands Displaying a Remarkable Agonistic−Antagonistic Profile at the Adenosine A₁ Receptor

  摘要：

  Adenosine receptor agonists are usually variations of the natural ligand, adenosine. The ribose moiety in the ligand has previously been shown to be of great importance for the agonistic effects of the compound. In this paper, we present a series of nonadenosine ligands selective for the adenosine A(1) receptor with an extraordinary pharmacological profile. 2-Amino-4-benzo[1,3]dioxol-5-yl-6-(2-hydroxyethylsulfanyl)pyridine-3,5-dicarbonitrile (70, LUF 5853) shows full agonistic behavior comparable with the reference compound CPA, while also displaying comparable receptor binding affinity (K-i = 11 nM). In contrast, compound 58 (2-amino-4-(3-trifluoromethylphenyl)-6-(2-hydroxyethylsulfanyl)pyridine-3,5-dicarbonitrile, LUF 5948) has a binding affinity of 14 nM and acts as an inverse agonist. Also present within this same series are compounds that show neutral antagonism of the adenosine A(1) receptor, for example compound 65 (2-amino-4-(4-difluoromethoxyphenyl)-6-(2-hydroxyethylsulfanyl)pyridine-3,5-dicarbonitrile, LUF 5826).

  Amino-3,5-Dicyanopyridines Targeting the Adenosine Receptors. Ranging from Pan Ligands to Combined A1/A2B Partial Agonists

  摘要：

  氨基-3,5-二氰吡啶衍生物属于一个引人注目的腺苷受体（AR）配体系列，这个系列是由学术研究人员和工业界共同开发的。事实上，迄今为止进行的研究强调了二氰吡啶骨架的多功能性，可以获得不仅具有广泛亲和力而且在不同AR上具有不同效力的AR配体。这些观察结果促使我们对这个系列的结构-活性关系（SARs）进行研究，从而得到了重要的先前报道的结果。当前的SAR研究有助于确认R2位置的1H-咪唑-2-基团是产生有效AR激动剂的重要特征。此外，R1取代基的性质不仅高度影响对hA1和hA2B AR的亲和力/活性，还影响对其他亚型的选择性。开发了有效的hA1和hA2B AR配体，其中2-氨基-6-[(1H-咪唑-2-基甲基)硫基]-4-[4-(丙-2-烯-1-氧基)苯基]吡啶-3,5-二腈（3）在这些亚型中的活性处于低纳摩尔范围，并显示出对hA2A和hA3 AR的良好选择性趋势。这种结合的hA1/hA2B部分激动剂活性对葡萄糖稳态产生协同效应，可能有助于治疗糖尿病及相关并发症。

  2-Aminopyridine-3,5-dicarbonitrile compounds were previously identified as mimetics of dominant-negative prion protein mutants and inhibit prion replication in cultured cells. Here, we report findings from a comprehensive structure-activity relationship study of the 6-aminopyridine-3,5-dicarbonitrile scaffold. We identify compounds with significantly improved bioactivity (approximately 40-fold) against

  2-Amino-4-aryl-6-mercaptopyridine-3,5-dicarbonitriles as starting materials have been prepared by reducing of 2-amino-4-aryl-6-(phenylthio)pyridine-3,5-dicarbonitrile derivatives which were synthesized on stepwise one-pot three component reaction of malononitrile, aldehydes and thiophenol in the presence of base catalysts such as triethylamine, high surface area (HSA) MgO or nanocrystalline magnesium oxide. Alkylation of 2-amino-4-aryl-6- mercaptopyridine-3,5-dicarbonitriles with alpha-halogen compounds in presence of sodium alkoxide as base catalyst followed with cyclization afforded thethieno[2,3-b]pyridine derivatives in excellent yields and in a short reaction time.
