In this paper we investigated the influence on affinity, selectivity and intrinsic activity upon modification of the adenosine agonist scaffold at the 3'- and 5'-positions of the ribofuranosyl moiety and the 2- and N6-positions of the purine base. This resulted in the synthesis of various analogues, that is, 3-12 and 24-33, with good hA3AR selectivity and moderate-to-high affinities (as in 32, Ki=27 nM). Interesting was the ability to tune the intrinsic activity depending on the substituent introduced at the 3'-position.
