Abstract
(N)-Methanocarba adenosine 5′-methyluronamides containing known A3 AR (adenosine receptor)-enhancing modifications, ie, 2-(arylethynyl) adenine and N 6-methyl or N 6-(3- substituted-benzyl), were nanomolar full agonists of human (h) A3AR and highly selective (K i∼ 0.6 nM, N 6-methyl 2-(halophenylethynyl) analogues 13 and 14). Combined 2- arylethynyl-N 6-3-chlorobenzyl substitutions preserved A3AR affinity/selectivity in the (N)- ...
