  Synthesis of hypermodified adenosine derivatives as selective adenosine A3 receptor ligands

  摘要：

  We investigated the A(3)AR affinity and selectivity of a series of 2-substituted 3'-azido and 3'-amino adenosine derivatives as well as some 5-uronamide derivatives thereof. All compounds showed high A3AR selectivity. While the 3'-azides appeared to be A3AR antagonists with moderate A3AR affinity, their 3'-amino congeners exhibit significantly improved A3AR affinity and behave as partial agonists. For both the 3'-azides and the 3'-amines, the 5'-methylcarbamoyl modification improved the overall affinity. Introduction of a 2-phenylethynyl substituent provided high affinity for the A3AR.
