区分化合物的激动或拮抗行为对于合理发现选择性调节剂非常有用。我们合成了截短的核苷衍生物并发现6c ( K i = 2.40 nM) 作为一种有效的人类 A 3腺苷受体 (hA 3 AR) 激动剂,并且细微的化学修饰诱导了从拮抗剂到激动剂的转变。我们通过开发新的 hA 3 AR 同源模型来阐明这种转变,该模型考虑了配体的药理学特征。结合分子动力学(MD)模拟和受体-配体复合物的三维(3D)结构网络分析,结果表明与Thr94的氢键为3.36和His272 7.43可以使3'-氨基与TM3和TM7形成稳定的相互作用,相应的诱导拟合效应可能在呈现激动效应中起重要作用。我们的结果为化合物在原子水平上的作用提供了更精确的理解,并为设计具有特定药理学特征的新药提供了基本原理。

A3 adenosinereceptor (AR) ligands including A3 AR agonist, N6-(3-iodobenzyl)adenosine-5'-N-methyluronamide (1a, IB-MECA) were examined for adiponectin production in human bone marrow mesenchymal stem cells (hBM-MSCs). In this model, 1a significantly increased adiponectin production, which is associated with improved insulin sensitivity. However, A3 AR antagonists also promoted adiponectin production
检查 A3 腺苷受体 (AR) 配体(包括 A3 AR 激动剂、N6-(3-碘苄基)腺苷-5'-N-甲基脲酰胺 (1a, IB-MECA))在人骨髓间充质干细胞 (hBM-MSC) 中的脂联素生成情况)。在该模型中,1a 显着增加了脂联素的产生,这与胰岛素敏感性的改善有关。然而,A3 AR 拮抗剂也促进 hBM-MSC 中脂联素的产生,表明 A3 AR 途径可能不直接参与脂联素促进活性。在一项靶标解卷积研究中,它们的脂联素促进活性与其与过氧化物酶体增殖物激活受体 (PPAR) γ 和 PPARδ 的结合活性显着相关。它们既充当 PPARγ 部分激动剂又充当 PPARδ 拮抗剂。在糖尿病小鼠模型中,1a 及其结构类似物 A3 AR 拮抗剂显着降低血清葡萄糖和甘油三酯水平,支持其抗糖尿病潜力。这些发现表明,这些化合物的多药效团可以为它们针对各种人类疾病的多效功效提供治疗见解。
