  5‘-Deoxy Congeners of 9-(3-Amido-3-deoxy-β-d-xylofuranosyl)-N⁶-cyclopentyladenine:  New Adenosine A₁ Receptor Antagonists and Inverse Agonists

  摘要：

  The synthesis and structure-activity relationship of AT6-cyclopentyl-3'-substituted-xylofuranosyladenosine analogues with respect to various adenosine receptors were explored in order to identify selective and potent antagonists and inverse agonists for the adenosine A(1) receptor. In particular, the effects of removal of the 5'-OH group and introduction of selected substituents at the 3'-NH2 position of 9-(3-amino-3-deoxy-beta-D-xylofuranosyl)-N-6-cyclopentyladenine were probed. A solid phase-assisted synthetic approach was used to optimize the 3'-amide functionality. In view of the general concern of the presence of a 5'-OH moiety with regard to cellular toxicity, the present study describes 5'-deoxy compounds with reasonable affinity for the human adenosine A, receptor. Interestingly, this study shows that optimization of the 3'-"up" amide sustituent can substantially compensate for the drop in affinity for the adenosine A, receptor, which is generally observed upon removal of the 5'-OH group. The fact that for several 3'-amido-substituted (5'-deoxy)-N-6-cyclopentyladenosine derivatives, guanosine 5'-triphosphate-induced shifts in K-i values were significantly lower than 1 implies that these analogues behave as inverse agonists. This is further supported by their 1,3-dipropyl-8-cyclopentylxanthine-like capacity to increase forskolin-induced adenosine cyclic 3',5'-phosphate production.
