  affinity adenosine receptor that functions by Gs mediated elevation of cAMP and subsequent downstream signaling. The receptor has been implicated in lung inflammatory disorders like COPD and asthma. Several potent and selective A2BAdoR antagonists have been reported in literature, however most of the compounds suffer from poor pharmacokinetic profile. Therefore, with the aim to identify novel, potent and

  甲2BA Dor是低亲和力腺苷受体，通过GS功能介导的cAMP的升高和随后的下游信号传导。该受体与肺炎性疾病如COPD和哮喘有关。在文献中已经报道了几种有效的和选择性的A 2B AdoR拮抗剂，但是大多数化合物的药代动力学特性较差。因此，为了鉴定具有改善的药代动力学特性的新颖，有效和选择性的A 2B AdoR拮抗剂，我们首先探索了更受约束的MRS-1754形式（4）。为了改善代谢稳定性，尝试了几种接头修饰，以取代黄嘌呤头基的C8位和末端苯环之间的酰胺接头以及不同的苯基或其他杂芳基。SAR优化导致鉴定了两种新型A 2B AdoR拮抗剂，即8- 1- [5-Oxo-1-（4-三氟甲基-苯基）-吡咯烷-3-基甲基] -1H-吡唑-4-基} -1 ，3-二丙基-黄嘌呤（31）和8-（1- 2-氧代-2- [4-（3-三氟甲基-苯基）-哌嗪-1-基]-乙基} -1H-吡唑-4-基）-1,3-二丙
