  2-Nitro analogues of adenosine and 1-deazaadenosine: synthesis and binding studies at the adenosine A1, A2A and A3 receptor subtypes

  摘要：

  The influence of nitro substituents on the properties of adenosine and 1-deazaadenosine was studied. Combination of a nitro group at the 2-position with several N-6 substituents such as cyclopentyl and m-iodobenzyl gave a series of analogues with good adenosine receptor affinity, showing directable selectivity for the A(1), A(2A) and A(3) adenosine receptor subtypes.

  Regioselective nitration of purine nucleosides: synthesis of 2-nitroadenosine and 2-nitroinosine

  摘要：

  Nitration reactions of 6-substituted purine nucleosides with tetrabutylammonium nitrate/trifluoroacetic anhydride (TBAN/TFAA) have been studied. This nitrating mixture selectively nitrates C-6 substituted purines at the 2-position, but the method is limited to substrates without NH or OH substituents. Acetylated 6-chloropurine riboside was cleanly nitrated (DCM, 0 degrees C, 71%) and converted to nitro substituted adenosine and inosine in a few simple steps. (C) 2000 Elsevier Science Ltd.
