  Structure−Activity Relationships of 2-Chloro-N⁶-substituted-4‘-thioadenosine-5‘-uronamides as Highly Potent and Selective Agonists at the Human A₃ Adenosine Receptor

  摘要：

  We have established structure-activity relationships of novel 4'-thionucleoside analogues as the A(3) adenosine receptor (AR) agonists. Binding affinity, selectivity toward other AR subtypes.. and efficacy in inhibition of adenylate cyclase were studied. From this study, 2-chloro-N-6-methyl-4'-thioadenosine-5'-methyluronamide (36a) emerged as the most potent and selective agonist at the human A(3) AR. We have also revealed that. similar to 4'-oxoadenosine analogues, at least one hydrogen on the 5'-uronamide moiety was necessary for high-affinity binding at the human A(3) AR, presumably to allow this group to donate a H bond within the binding site. Furthermore, bulky substituents on the 5'-uronarnide reduced binding affinity, but in some cases large 5'-uronamide substituents, such as substituted benzyl and 2-phenylethyl groups. maintained moderate affinity with reduced efficacy, leading to A(3) AR partial agonists or antagonists. In several cases for which the corresponding 4'-oxonucleosides have been studied, the 4'-thionucleosides showed higher binding affinity to the A(3) AR.

  4'-Thio analogues 3-5 of Cl-IB-MECA (2) (K-i = 1.0 +/- 0.2 nM at the human A(3) adenosine receptor) were synthesized from D-gulono-gamma-lactone via 4-thioribosyl acetate 14 as the key intermediate. All synthesized 4-thionucleosides exhibited higher binding affinity to the human A(3) adenosine receptor than Cl-IB-MECA, among which 4 showed the most potent binding affinity (K-i = 0.28 +/- 0.09 nM). 4 was also selective for A(3) vs human A(1) and human A(2A) receptors by 4800- and 36000-fold, respectively.

  4'-Thionucleoside derivatives as potent and selective A(3) adenosine receptor agonists were synthesized, starting from D-gulono-gamma-lactone via D-thioribosyl acetate as a key intermediate, among which the 2-chloro-N-6-methyladenosine-5'-methyluronamide showed the most potent and selective binding affinity (K-i = 0.28 +/- 0.09 nM) at the human A(3) adenosine receptor.
