Ogerin is a selective GPR68 positive allosteric modulator (pEC50: 6.83) that blocks recall in fear conditioning in mice. It exhibits inverse agonist and antagonist activity (Ki, 220 nM) at the A2A receptor and weak antagonist activity (Ki, 736 nM) at the 5-HT2B receptor.

SCH442416 (SCH 442416) is an selective antagonist of adenosine A2A receptor. SCH442416 binds to human and rat A2A receptors with high affinity (Ki values are 0.048 and 0.5 nM respectively).

Regadenoson (CVT-3146) is an adenosine derivative and selective A2A adenosine receptor agonist with coronary vasodilating activity. Upon administration, regadenoson selectively binds to and activates the A2A adenosine receptor, which induces coronary vasodilation. This leads to an increase in coronary blood flow and enhances myocardial perfusion. Compared to adenosine, regadenoson has a longer half-life and shows higher selectivity towards the A2A adenosine receptor. This agent is a very weak agonist for the A1 adenosine receptor and has negligible affinity for the A2B and A3 adenosine receptors.
