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.

While it is well known that adenosine receptor activation protects the heart from ischemia/reperfusion injury, the precise mitochondrial mechanism responsible for the action remains unknown. This study probed the mitochondrial events associated with the cardioprotective effect of 5'-(N-ethylcarboxamido) adenosine (NECA)
