title: 2-Nitro analogues of adenosine and 1-deazaadenosine: synthesis and binding studies at the adenosine A1, A2A and A3 receptor subtypes.
abstract: 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 N6 substituents such as cyclopentyl and m-iodobenzyl gave a series of analogues with good adenosine receptor affinity, showing directable selectivity for the A1, A2A and A3 adenosine receptor subtypes.
