derivatives were less potent than corresponding 8‐styrylcaffeine derivatives at adenosine receptors. The most potent azo compound of the present series was 8‐(m‐chlorophenylazo)caffeine (14b) exhibiting a Ki value of 400 nM at A2A‐adenosine receptors and 20‐fold selectivity versus A1‐receptors. Due to the facile synthetic access to 8‐(phenylazo)xanthine derivatives, which are obtained by coupling of 8‐unsubstituted
