  3′-Amidated 3′-Deoxyxylofuranose Analogues of N ⁶-⁻Cyclopentyladenosines: a New Class of Non-Xanthine Antagonists at the Adenosine A₁ Receptor.

  摘要：

  Full adenosine A(1) receptor agonists like CPA and other N-6-substituted adenosine analogs have previously been shown to become partial agonists upon deletion of the 3'-hydroxyl moiety. The present study further explored the C-3' site for modification. The modest affinity at A(1) and A(2a) receptors found in the 3'-amido-3'-deoxyxylofuranosyladenine series prompted us to synthesize the corresponding N-6-cyclopentyl derivatives, which proved to exhibit potent antagonistic behaviour at the A(1) receptors. This represents a new perspective in the purinergic field.

  The present study explores the C-3' site of the 3-deoxy-3-xylofuranosyl ring of nucleoside analogues with an adenine or N-6-cyclopentyladenine (CPA) base moiety and evaluates the effect on adenosine receptor affinity. Two series of sugar-modified adenosines, i.e., 3'-amido-3'-deoxyadenosines and 3'-amidated 3'-deoxyxylofuranosyladenines, were synthesized and tested for their affinity at A(1) and A(2a) receptors in rat brain cortex and rat striatum, respectively. The modest affinity found in the ''xylo series'' prompted us to synthesize the corresponding N-6-cyclopentyl derivatives, which proved to be well accommodated by the A(1) receptors with potencies in the lower nanomolar range. This represents a new perspective in the purinergic field. The absence of a GTP-induced shift, i.e., the ratio between the affinities measured in the presence and absence of 1 mM GTP indicates an antagonistic behavior of this new class of CPA analogues.
