Two series of 5-substituted 2-amino-4-(3-trifluoromethylphenyl)thiophenes were prepared and evaluated as allosteric enhancers at the A(1) adenosine receptor (A(1)AR). In the 3-benzoyl series, a 5-phenyl group was found to confer the greatest potency (9a: ED(50)=2.1 microM, AE score=18%). However, the analogue
