  Extended N6 substitution of rigid C2-arylethynyl nucleosides for exploring the role of extracellular loops in ligand recognition at the A3 adenosine receptor

  摘要：

  2-Arylethynyl-(N)-methanocarba adenosine 5'-methyluronamides containing rigid N-6-(trans-2-phenylcyclopropyl) and 2-phenylethynyl groups were synthesized as agonists for probing structural features of the A(3) adenosine receptor (AR). Radioligand binding confirmed A(3)AR selectivity and N-6-1S,2R stereoselectivity for one diastereomeric pair. The environment of receptor-bound, conformationally constrained N-6 groups was explored by docking to an A(3)AR homology model, indicating specific hydrophobic interactions with the second extracellular loop able to modulate the affinity profile. 2-Pyridylethynyl derivative 18 was administered orally in mice to reduce chronic neuropathic pain in the chronic constriction injury model.
