Tópico(s)Synthesis and Characterization of Heterocyclic Compounds
ResumoNovel d- and l-4′-thioadenosine derivatives lacking the 4′-hydroxymethyl moiety were synthesized, starting from d-mannose and d-gulonic γ-lactone, respectively, as potent and selective species-independent A3 adenosine receptor (AR) antagonists. Among the novel 4′-truncated 2-H nucleosides tested, a N6-(3-chlorobenzyl) derivative 7c was the most potent at the human A3 AR (Ki = 1.5 nM), but a N6-(3-bromobenzyl) derivative 7d showed the optimal species-independent binding affinity.
