  Truncated Nucleosides as A₃ Adenosine Receptor Ligands: Combined 2-Arylethynyl and Bicyclohexane Substitutions

  摘要：

  C2-Arylethynyladenosine-5'-N-methyluronamides containing a bicyclo[3.1.0]hexane [(N)-methanocarba] ring are selective A(3) adenosine receptor (AR) agonists. Similar 4'-truncated C2-arylethynyl-(N)-methanocarba nucleosides containing alkyl or alkylaryl groups at the N-6 position were low-efficacy agonists or antagonists of the human A(3)AR with high selectivity. Higher hA(3)AR affinity was associated with N-6-methyl and ethyl (K-i = 3-6 nM) than with N-6-arylallcyl groups. However, combined C2-phenylethynyl and N-6-2-phenylethyl substitutions in selective antagonist 15 provided a K-i of 20 nM. Differences between 4'-truncated and nontruncated analogues of extended C2-p-biphenylethynyl substitution suggested a ligand reorientation in AR binding, dominated by bulky N-6 groups in analogues lacking a stabilizing S'-uronamide moiety. Thus, 4'-truncation of C2-arylethynyl-(N)-methanocarba adenosine derivatives is compatible with general preservation of A(3)AR selectivity, especially with small N-6 groups, but reduced efficacy in A(3)AR-induced inhibition of adenylate cyclase.

  (N)-Methanocarba nucleosides containing bicyclo[3.1.0]hexane replacement of the ribose ring previously demonstrated selectivity as A3 adenosine receptor (AR) agonists (5′-uronamides) or antagonists (5′-truncated). Here, these two series were modified in parallel at the adenine C2 position. N6-3-Chlorobenzyl-5′-N-methyluronamides derivatives with functionalized 2-alkynyl chains of varying length terminating
