potent, structurally simple, and highly selective A1AR ligands. The most attractive ligands were confirmed as antagonists of the canonical cyclic adenosine monophosphate pathway, and some pharmacokinetic parameters were preliminarilly evaluated. The library, built through a reliable and efficient three-component reaction, comprehensively explored the chemical space allowing the identification of the
我们在此记录了大量 108 种 2-氨基-4,6-二取代-嘧啶衍生物,作为有效、结构简单且高度选择性的 A 1 AR 配体。最有吸引力的配体被确认为经典环磷酸腺苷途径的拮抗剂,并初步评估了一些药代动力学参数。该库通过可靠且高效的三组分反应构建,全面探索了化学空间,从而识别了该支架周围结构-活性和结构-选择性关系的最突出特征。其中包括对嘧啶核心 R 4和 R 6位置芳香族残基选择性谱的影响,但最重要的是,在环外氨基处引入的甲基对前所未有的 A 1 AR 选择性谱发挥了突出作用。 A 1和 A 2A AR 的结构-活性关系趋势可以通过严格的自由能扰动模拟方便地解释,该模拟从指导这些系列设计的受体驱动对接模型开始。

New adenosine receptor ligands were designed as hybrid structures between previously synthesized substituted dicyanopyridines and aminopyrimidines, yielding two series of cyano-substituted diphenylaminopyrimidines. We were interested in assessing the effect of this substitution pattern on both affinity and intrinsic activity, as the dicyanopyridines comprised both agonists and inverse agonists, whereas

An expedient route for the synthesis of libraries of diversely decorated 2-aminopyrimidine-5-carbonitriles is reported. This approach is based on a three-component reaction followed by spontaneous aromatization.
