  Design and synthesis of N6-substituted-4′-thioadenosine-5′-uronamides as potent and selective human A3 adenosine receptor agonists

  摘要：

  On the basis of a bioisosteric rationale, 4'-thionucleoside analogues of IB-MECA (N-6-(3-Iodo-benzyl)-9-(5'-methylaminocarbonyl-beta-D-ribofuranosyl)adenine), which is a potent and selective A(3) adenosine receptor (AR) agonist, were synthesized from D-gulonic acid gamma-lactone. The 4'-thio analogue (5h) of IB-MECA showed extremely high binding affinity (K-i = 0.25 nM) at the human A(3)AR and was more potent than IB-MECA (K-i = 1.4 nM). Bulky substituents at the 5'-uronamide position, such as cyclohexyl and 2-methylbenzyl, in this series of 2-H nucleoside derivatives were tolerated in A3AR binding, although small alkyl analogues were more potent.
