Novel D- and l-4'-thioadenosine derivatives lacking the 4'-hydroxymethyl moiety were synthesized, starting from d-mannose and d-gulonic gamma-lactone, respectively, as potent and selective species-independent A 3 adenosine receptor (AR) antagonists. Among the novel 4'-truncated 2-H nucleosides tested, a N(6)-(3-chlorobenzyl) derivative 7c was the most potent at the human A 3 AR (K i = 1.5 nM), but a N(6)-(3-bromobenzyl) derivative 7d showed the optimal species-independent binding affinity. ...[more]
