A1AR antagonists compared to pyrrolo[2,3-d]pyrimidines. Compound 34a (APEPI) is one of the most potent and most selective nonxanthine A1AR antagonists known to date (Ki = 2.8 nM, > 2000-fold A1-selective). A new class of very potent A1AR antagonists has been identified, namely, 2-phenyl-7-deazaadenines bearing a substituent at the exocyclic amino group (N4-substituted pyrrolo[2,3-d]pyrimidines). (R)-N-

fluorescent properties. Pyrrolo[2,3-d]pyrimidine-4-amine derivatives which were simultaneously substituted at N7 and N(4), combining the substitution pattern of ADPEP (1) and DPEAP (2), showed very low affinity for A(1) ARs. This finding supports our previously published hypothesis of different binding modes for pyrrolopyrimidines, such as ADPEP (1) and DPEAP (2). DPEAP (2), a pyrrolo[2,3-d]pyrimidine-4-amine
