Disclosed are (N)-methanocarba adenine nucleosides, e.g., of the formula (I): as A3 adenosine receptor agonists, pharmaceutical compositions comprising such nucleosides, and a method of use of these nucleosides, wherein A, a, R2, and R3 are as defined in the specification. These nucleosides are contemplated for use in the treatment a number of diseases, for example, inflammation, cardiac ischemia, stroke, asthma, diabetes, and cardiac arrhythmias. Also disclosed are conjugates comprising a dendrimer and one or more ligands, which are functionalized congeners of an agonist or antagonist of a receptor of the G-protein coupled receptor (GPCR) superfamily. Such conjugates are have the potential of being used as dual agonists, dual antagonists, or agonist/antagonist combinations.
揭示了(N)-methanocarba腺嘌呤核苷,例如,化学式(I)所示的腺苷受体A3激动剂,包括这种核苷的药物组合物,以及这些核苷的使用方法,其中A、a、R2和R3如规范中定义。这些核苷被考虑用于治疗多种疾病,例如炎症、心脏缺血、中风、哮喘、糖尿病和心律失常。还揭示了包括树枝状聚合物和一个或多个配体的共轭物,这些配体是G蛋白偶联受体(GPCR)超家族受体的激动剂或拮抗剂的功能化同系物。这种共轭物有潜力用作双激动剂、双拮抗剂或激动剂/拮抗剂组合物。
