  描述：

  8-pyridin-2-yl-1H-[1,2,4]triazolo[5,1-f]purin-5-amine 在 sodium hydride 作用下， 以 N,N-二甲基甲酰胺 为溶剂， 生成 3-[2-[4-[4-(2-Methoxyethoxy)phenyl]piperazin-1-yl]ethyl]-8-pyridin-2-yl-[1,2,4]triazolo[5,1-f]purin-5-amine

  名称：

  3H-[1,2,4]-Triazolo[5,1-i]purin-5-amine derivatives as adenosine A2A antagonists

  摘要：

  A novel series of 3-substituted-8-aryl-[1,2,4]-triazolo[5,1-i]purin-5-amine analogs related to Sch 58261 was synthesized in order to identify potent adenosine A(2A) receptor antagonists with improved selectivity over the A(1) receptor, physiochemical properties, and pharmacokinetic profiles as compared to those of Sch 58261. As a result of structural modifications, numerous analogs with excellent in vitro binding affinities and selectivities were identified. Moreover, compound 27 displayed both superior in vitro and highly promising in vivo profiles. (c) 2007 Elsevier Ltd. All rights reserved.
