MRS 1523 can exert an antihyperalgesic effect through N-type Ca channel block and action potential inhibition in isolated rat dorsal root ganglion (DRG) neurons. MRS 1523 is an effective and selective adenosine A3receptor antagonist Ki: 18.9 nM and 113 n
MRS-1191 is an effective and selective A3 adenosine receptor antagonist (KB: 92 nM, a Ki: 31.4 nM for humanA3receptor and an IC50: 120 nM for CHO cells).
Adenosine receptor inhibitor 1 is a highly potent and selective antagonist of adenosine receptor (AR). It exhibits exceptional affinity for A1 AR, A2A AR, A2B AR, and A3 AR, with respective Ki values of >1000, 68.5, >1000, >1000 nM. This compound demonstrates notable antinociceptive, anti-inflammatory, and peripheral analgesic properties. Therefore, Adenosine receptor inhibitor 1 holds great promise for investigating cancer and neurodegenerative diseases [1].
