  家族 2 和家族 10 的植物醛脱氢酶氧化咪唑和吡唑衍生的醛

  摘要：

  家族 2 的植物胞质醛脱氢酶（ALDH2，EC 1.2.1.3）是非特异性酶，参与乙醛的代谢或苯丙素的生物合成等。植物氨基醛脱氢酶（AMADH、ALDH10 家族、EC 1.2.1.19）具有广泛的特异性，在多胺降解或渗透保护剂的产生中发挥着重要作用。我们测试了咪唑和吡唑甲醛及其烷基、烯丙基、苄基、苯基、嘧啶基或噻吩基衍生物作为植物 ALDH2 和 ALDH10 酶的可能底物。咪唑是组氨酸、组胺以及某些生物碱的组成部分。它也出现在合成药物中，例如咪唑抗真菌剂。含有吡唑的生物化合物很少见（例如吡唑-1-丙氨酸和吡唑呋林抗生素），但该环经常作为许多合成药物和农药的成分被发现。目的是评估基于唑杂环的醛化合物是否被酶氧化，这将进一步支持它们作为解毒醛清除剂的预期作用。所分析的咪唑和吡唑甲醛仅被 ALDH10 缓慢转化，但被胞质玉米 ALDH2 异构体（特别是 ALDH2C1）充分氧化。在后一种情况下，各自的K

  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
