Biochem/physiol Actions

MRS-1706 is a high-affinity, potent and selective adenosine 2B receptor (A2B) antagonist/inverse agonist (human A1/A2A/A2B/A3 Ki = 157/112/1.39/230 nM; rat A1/A2A Ki = 37.6/548 nM). MRS-1706 (20 nM), but not the A2A antagonist SCH 58261 (20 nM), completely blocks the enhancement of electrically evoked tritium overflow from isolated rat tail artery by 10 μM adenosine receptor agonist NECA in the presence of 30 nM A1 antagonist DPCPX.

Adenosine receptors involved in the modulation of noradrenaline release from postganglionic sympathetic nerves in rat tail artery were characterized by studying the effects of adenosine-receptor agonists and antagonists on electrically evoked tritium overflow (100 pulses, 5 Hz) and by immunohistochemistry.

The human adenosine A(2B) receptor belongs to class A G protein-coupled receptors (GPCRs). In our previous work, constitutively active mutant (CAM) human adenosine A(2B) receptors were identified from a random mutation bank. In the current study, three known A(2B) receptor

No highly selective antagonists of the A(2B) adenosine receptor (AR) have been reported; however such antagonists have therapeutic potential as antiasthmatic agents. Here we report the synthesis of potent and selective A(2B) receptor antagonists. The structure-activity relationships (SAR) of 8-phenyl-1
