  Structure-Activity Relationships of N6-Benzyladenosine-5'-uronamides as A3-Selective Adenosine Agonists

  摘要：

  Adenosine analogues modified at the 5'-position as uronamides and/or as N-6-benzyl derivatives were synthesized. These derivatives were examined for affinity in radioligand binding assays at the newly discovered rat brain A(3) adenosine receptor and at rat brain A(1) and Az, receptors. 5'Uronamide substituents favored AS selectivity in the order N-methyl > N-ethyl approximate to unsubstituted carboxamide > N-cyclopropyl. 5'-(N-Methylcarboxamido)-N-6-benzyladenosine was 37-56-fold more selective for Ag receptors. Potency at A(3) receptors was enhanced upon substitution of the benzyl substituent with nitro and other groups. 5'-N-Methyluronamides and N-6-(3-substituted-benzyl) adenosines are optimal for potency and selectivity at A(3) receptors. A series of 3-(halobenzyl)5'-N-ethyluronamide derivatives showed the order of potency at A(1) and A(2)a receptors of I similar to Br > Cl > F. At A(3) receptors the 3-F derivative was weaker than the other halo derivatives. 5'-N-Methyl-N-6- (3-iodobenzyl) adenosine displayed a K-i value of 1.1 nM at A(3) receptors and selectivity versus A(1) and A(2a), receptors of 50-fold. A series of methoxybenzyl derivatives showed that a C-methoxy group best favored A(3) selectivity. A 4-sulfobenzyl derivative was a specific ligand at A(3) receptors of moderate potency. An aryl amino derivative was prepared as a probe for radioiodination and receptor cross-linking.
