  2-(N-Acyl) and 2-N-acyl-N6-substituted analogues of adenosine and their affinity at the human adenosine receptors

  摘要：

  A series of 2-(N-acyl) and 2-(N-acyl)-N-6-alkyladenosine analogues have been synthesized from the intermediate 2-amino-6-chloroadenosine derivatives (2b and 7) and evaluated for their affinity at the human A(1), A(2A), and A(3) receptors. We found that 2-(N-acyl) derivatives of adenosine showed relatively low affinity at A(2A) and A(3) receptors, while the N-6-cyclopentyl substituent in 4h and 4i induced high potency [A(1) (K-i) = 20.7 and 31.8 nM respectively] at the A(1) receptor and resulted therefore in increased selectivity for this subtype. The general synthetic methods and their binding studies are presented herein. (C) 2004 Elsevier Ltd. All rights reserved.
