  Ribose-Modified Adenosine Analogs as Potential Partial Agonists for the Adenosine Receptor

  摘要：

  We have adopted a practical three-step route for the synthesis of 2'- and 3'-deoxy analogues of N-6-substituted adenosines: protection of the hydroxyl groups, replacement of the N-6-amino by a better leaving group, and combined deprotection and N-6-amination in the last step. This route was used to synthesize deoxy analogues of CPA, CHA, and R- and S-PIA. The compounds were tested on the adenosine A(1) and A(2a) receptors in our search for partial agonists for these receptors. The GTP shift was used as an in vitro measure for the intrinsic activity of these compounds; the in vivo intrinsic activities of the deoxy analogues of CPA and R-PIA were determined in the rat cardiovascular system. Thus, it was shown that the hydroxyl groups are determinants for the affinity and intrinsic activity of these analogues. Removal of the 2'-and 3'-hydroxyl groups affects affinity and intrinsic activity, whereas removal of the 5'-hydroxyl group decreases only affinity.

  A number of cycloalkyl substituents (from C-3 to C-8) have been int-reduced on the 6-amino group of adenosine, 1-deazaadenosine, and 2'-deoxyadenosine, bearing or not a chlorine atom at the 2-position, to evaluate the influence on the A(1) and A(2A) affinity of steric hindrance and lipophilicity. Furthermore, the guanosine 5'-triphosphate (GTP) shift and the maximal induction of guanosine 5'-(gamma-thio)triphosphate ([S-35]GTP gamma S) binding to G proteins in rat brain membranes were used to determine the intrinsic activity of these nucleosides at the A(1) adenosine receptor. All compounds of the ribose-bearing series proved to be full agonists, the 1-deaza derivatives showing affinities for the Al receptor about 10-fold lower than the corresponding adenosines. On the other hand, all the 2'-deoxyribose derivatives bind to the A(1) receptor with affinities in the high nanomolar range, with the 2-chloro substituted compounds showing slightly higher affinities than the 2-unsubstituted counterparts. In terms of the potencies, the most potent compounds proved to be those bearing four- and five-membered rings. Both GTP shifts and [S-35]-GTP gamma S experiments showed that most of the 2'-deoxyadenosine derivatives are partial agonists, The 2'-deoxyadenosine derivatives which were identified as partial agonists consistently detected fewer Az receptors in the high-affinity state than full agonists. However, it is worthwhile noting that there was not a simple Linear relationship between receptor occupancy and activation. These results indicate that a critical density of A(1) adenosine receptors in the high-affinity state is required for G protein activation.
