Disclosed are (N)-methanocarba adenine nucleosides, e.g., of the formula (I): as A
3
adenosine receptor agonists, pharmaceutical compositions comprising such nucleosides, and a method of use of these nucleosides, wherein A, a, R
2
, and R
3
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.
本发明涉及(N)-methanocarba腺嘌呤核苷,例如式(I)的核苷,作为A3腺苷受体激动剂,包含此类核苷的制药组合物以及使用这些核苷的方法,其中A,a,R2和R3如规范中所定义。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。本发明还涉及包含树状分子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。这样的共轭物具有作为双重激动剂,双重拮抗剂或激动剂/拮抗剂组合物的潜力。
