  2-Amino-6-furan-2-yl-4-substituted Nicotinonitriles as A_2A Adenosine Receptor Antagonists

  摘要：

  A2A adenosine receptor antagonists usually have bi- or tricyclic N aromatic systems with varying substitution patterns to achieve desired receptor affinity and selectivity. Using a pharmacophore model designed by overlap of nonxanthine type of previously known A2A antagonists, we synthesized a new class of compounds having a 2-amino nicotinonitrile core moiety. From our data, we conclude that the presence of at least one furan group rather than phenyl is beneficial for high affinity on the A2A adenosine receptor. Compounds 39 (LUF6050) and 44 (LUF6080) of the series had Ki values of 1.4 and 1.0 nM, respectively, with reasonable selectivity toward the other adenosine receptor subtypes, A,, A2B, and A3. The high affinity of 44 was corroborated in a cAMP second messenger assay, yielding subnanomolar potency for this compound.

  Polyfunctional 4-(3-cyanopyridin-2-ylthio)acetoacetates were used in the synthesis of 4-hydroxy-1H-thieno[2,3-b:4,5-b]dipyridin-2-ones. The latter were used in reactions with arylidene-malononitriles or in three-component reactions with aldehydes and malononitrile to give 2-amino-4-aryl-3-cyano-5-oxo-5,6-dihydro-4H-pyrano[2,3-d]pyrido[3',2':4,5]thieno[3,2-b]pyridines. Utilizing 4-(3-cyanopyridin-2

  多官能团 4-(3-cyanopyridin-2-ylthio)acetoacetates 用于合成 4-hydroxy-1H-thieno[2,3-b:4,5-b]dipyridin-2-ones。后者用于与亚芳基-丙二腈的反应或与醛和丙二腈的三组分反应，得到 2-amino-4-aryl-3-cyano-5-oxo-5,6-dihydro-4H-pyrano[2, 3-d]吡啶并[3',2':4,5]噻吩并[3,2-b]吡啶。利用 4-(3-cyanopyridin-2-ylthio)acetoacetates 和亚芳基丙二腈或醛和丙二腈，我们开发了一种合成取代的 3-alkoxycarbonyl-6-amino-4-aryl-2-(3-cyanopyridin-2-基硫甲基）-4H-吡喃。取代的 4-(3-cyanopyridin-2-ylthio)acetoacetates 与水合肼反应生成取代的
