prototypical A1AR agonists has been hindered due to dose limiting adverse effects. Recently, we demonstrated that the biased bitopic agonist 1, consisting of an adenosine pharmacophore linked to an allosteric moiety, could stimulate cardioprotective A1AR signaling in the absence of unwanted bradycardia. Therefore, this study aimed to investigate the structure–activity relationship of compound 1 biased
腺苷A 1受体(A 1 AR)是心肌缺血再灌注损伤的潜在新型治疗靶标。但是,迄今为止,由于剂量限制的不良反应,原型A 1 AR激动剂的临床翻译受到了阻碍。最近,我们证明,由连接至变构部分的腺苷药效基团组成的偏向性双位激动剂1可以在不存在心动过缓的情况下刺激心脏保护性A 1 AR信号传导。因此,本研究旨在研究化合物1激动剂的构效关系。一系列的新的衍生物的1合成并进行药理学分析。对正构腺苷药效团,接头和变构2-氨基-3-苯甲酰基噻吩药效团进行了修饰,以探究其结构-活性关系,特别是在信号偏向方面以及A 1 AR活性和亚型选择性方面。总的来说,我们的发现表明,变构部分,特别是噻吩支架的4-(三氟甲基)苯基取代基,在赋予A 1 AR上的双位配体偏倚方面很重要。
