[3H]OSIP339391, a selective, novel, and high affinity antagonist radioligand for adenosine A2B receptors

Until recently, the characterization of adenosine A2B receptors has been hampered by the lack of high affinity radioligands. This study describes the synthesis and in vitro characterization of the radiolabeled derivative of OSIP339391, a novel,
