It has been used in trials studying the treatment and basic science of Drug Abuse, Sleep Disorder, Hepatic Impairment, Parkinson's Disease, and Restless Legs Syndrome, among others.

N6-Ethyladenosine, an adenosine derivative, acts as an agonist of Adenosine receptors (hA1AR and hA3AR) with Ki values of 4.9 nM and 4.7 nM, respectively.

Tozadenant (SYN115) is an adenosine A2A receptor antagonist(Ki of 11.5 nM and 6 nM on human and rhesus,respectively)

AB928 is an orally bioavailable, selective dual adenosine receptor (A2aR/A2bR) antagonist. It has immunomodulatory activity[1].

CGS 15943 is an orally bioavailable non-xanthine antagonist of the Adenosine Receptor. In transfected CHO cells, its Ki values for human A1, A2A, A2B, and A3 Adenosine Receptors are 3.5, 4.2, 16, and 50 nM, respectively.

MRS-1706 has Ki values of 1.39, 112, 157, and 230 nM for human A2B, A2A, A1, and A3 receptors respectively. MRS-1706 is an effective and selective adenosine A2B receptor inverse agonist.

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).

Vipadenant (CEB-4520)(BIIB-014) is an adenosine A2a antagonist with Ki of 1.3 nM; less potent for A1(Ki=69 nM).

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.

AZD4635 (HTL1071) is a new-type adenosine 2A receptor (A2AR) inhibitor(Ki=1.7 nM).
