  Agonists for the Adenosine A₁ Receptor with Tunable Residence Time. A Case for Nonribose 4-Amino-6-aryl-5-cyano-2-thiopyrimidines

  摘要：

  We report the synthesis and evaluation of previously unreported 4-amino-6-aryl-5-cyano-2-thiopyrimidines as selective human adenosine A(1) receptor (hA(1)AR) agonists with tunable binding kinetics, this without affecting their nanomolar affinity for the target receptor. They show a very diverse range of kinetic profiles (from 1 min (compound 52) to 1 h (compound 43)), and their structure-affinity relationships (SAR) and structure-kinetics relationships (SKR) were established. When put in perspective with the increasing importance of binding kinetics in drug discovery, these results bring new evidence of the consequences of affinity-only driven selection of drug candidates, that is, the potential elimination of slightly less active compounds that may display preferable binding kinetics.

  Notwithstanding the combination of cholinesterase (ChE) inhibition and calcium channel blockade within a multitarget therapeutic approach is envisaged as potentially beneficial to confront Alzheimer's disease (AD), this strategy has been scarcely investigated. To explore this promising line, a series of 5-amino-4-aryl-3,4,6,7,8,9-hexahydropyrimido [4,5-b]quinoline-2(1H)-thiones (tacripyrimidines) (4a-l)

  尽管在多靶点治疗方法中胆碱酯酶（ChE）抑制和钙通道阻滞相结合被认为对对抗阿尔茨海默氏病（AD）具有潜在的益处，但几乎没有研究这种策略。为了探索这一有前途的路线，一系列的5-氨基-4-芳基-3,4,6,7,8,9-六氢嘧啶基[4,5-b]喹啉-2（1 H）-硫酮（tacripyrimidines）（通过并置他克林，一种ChE抑制剂（ChEI）和3,4-二氢嘧啶-2（1 H）-硫酮设计了4a - 1）作为有效的钙通道阻滞剂（CCBs）。根据其设计，所有tacripyrimidines，未取代的母体化合物及其p-甲氧基衍生物，起中等至强效CCB的作用，其活性通常与参考CCB药物尼莫地平相似或更高，并且是中等至良好的ChEI。最有趣的是，3'-甲氧基衍生物（4e）作为第一种平衡良好的ChEI / CCB试剂出现，起低微摩尔hChEI（分别在hAChE和hBuChE上分别为3.05μM和3.19μM）和中等CCB（1μM时为30
