Following the demonstration that substitution of 1-phenylpyrazolo[3,4-d]pyrimidines at C6 with thioethers containing amide moieties could effect adenosine A(1) and A(2a) receptor selectivity, two compounds with high A(1) selectivity have been obtained by a combined C4, C6 substitution. This further demonstrates that distal moieties at C6 can effect selectivity and that C4 substitutents have an important role.
