Adenosine has been suggested to play a role in asthma, possibly via activation of A(2B) adenosine receptors on mast cells and other pulmonary cells. We describe our initial efforts to discover a xanthine based selective A(2B) AdoR antagonist that resulted in the discovery of CVT-5440, a high affinity A(2B) AdoR antagonist with good selectivity (A(2B) AdoR K-i = 50 nM, selectivity A(1) > 200: A(2A) > 200: A(3) > 167).
