Adenosine Receptors

SYN115 is an orally administered, potent and selective inhibitor of the adenosine 2a (A2a) receptor that is being developed initially for the treatment of Parkinson?€?s disease, but may also have utility in other CNS disorders.

CGS 21680 is a specific adenosine A2A subtype receptor agonist.

N-[(4-Aminophenyl)methyl]adenosine is a adenosine receptor inhibitor, with Ki of 29 nM for Rat ecto-5??-Nucleotidase. IC50 value: 29.0 ± 1.7 nM (Ki) Target: Adenosine Receptor

SCH 442416 is a selective adenosine A2A receptor antagonist; binds to human and rat A2A receptors with high affinity (Ki values are 0.048 and 0.5 nM respectively). Displays > 23000-fold selectivity for hA2A over hA1 in vitro with minimal affinity for hA2B and hA3 receptors (IC50 > 10 μM).

MT-DADMe-ImmA is an inhibitor of human 5'-methylthioadenosine phosphorylase (MTAP) with a Ki of 90 pM.

IB-MECA has been shown to act as a potent and selective Adenosine A3-R agonist with Ki values of 1.1, 54 and 56 nM for Adenosine A3-R, Adenosine A1-R and Adenosine A2A-R, respectively.

N6-Ethyladenosine is an adenosine derivative, acts as a Adenosine receptor agonist, with Kis of 4.9 and 4.7 nM for hA1AR and hA3AR, respectively.

Tonapofylline (BG 9928) is an orally active and selective adenosine A1 receptor antagonist with a Ki of 7.4 nM for human adenosine A1 receptor (hA1), which displays 915-fold selectivity versus human adenosine A2A receptor and 12-fold selectivity versus human adenosine A2B receptor and is used in development for the treatment of heart failure.

MRS 1754 is a selective antagonist radioligand for A2B adenosine receptor with very low affinity for A1 and A3 receptors of both humans and rats.

AB928 is an orally bioavailable, selective dual adenosine receptor (A2aR/A2bR) antagonist. AB928 relieves adenosine-mediated immune suppression. AB928 has immunomodulatory and antitumor activities.
