The synthesis of a new family of A(1)-adenosine receptor (A(1)AR) ligands 3a-n has been performed in a straightforward way. Affinity data at A(1)AR, A(2)AAR and A(3)AR in bovine membranes show that these new compounds bind the A(1)AR in a selective way over A(2A)AR and A(3)AR and one of them (3j) presents a very high affinity, probably due to the phenethylamine substituent at C-4.
