  N⁶-Methoxy-2-alkynyladenosine Derivatives as Highly Potent and Selective Ligands at the Human A₃ Adenosine Receptor

  摘要：

  A new series of N-6-methoxy-2-(ar)alkynyladenosine derivatives has been synthesized and tested at the human recombinant adenosine receptors. Binding studies demonstrated that the new compounds possess high affinity and selectivity for the A(3) subtype. Among them, compounds bearing an N-methylcarboxamido substituent in the 4'-position showed the highest A(3) affinity and selectivity. In particular, the N-6-methoxy-2-p-acetylphenylethynylMECA (40; K-i A(3) = 2.5 nM, A(3) selectivity versus A(1) = 21 500 and A(2A) = 4200) results in one of the most potent and selective agonists at the human A(3) adenosine receptor reported so far. Furthermore, functional assay, performed with selected new compounds, revealed that the presence of an alkylcarboxamido group in the 4'-position seems to be essential to obtain full agonists at the A(3) subtype. Finally, results of molecular docking analysis were in agreement with binding and functional data and could explain the high affinity and potency of the new compounds.
