2-chloro-3-Deazaadenosine, a stable analog of adenosine, is an agonist for adenosine receptors [1].

Adenosine receptors are members of G-protein-coupled receptors (GPCRs). Extracellular adenosine acts as a local modulator with a generally cytoprotective function in the body. Extracellular adenosine has been implicated in increasing the ratio of oxygen supply to demand, protecting against ischaemic damage by cell conditioning, triggering anti-inflammatory responses and the promotion of angiogenesis [2].

In vitro: The Ki values of 2-chloro-3-Deazaadenosine for A1, A2A, A2B, and A3 receptors were 0.3, 0.08, 25.5, and 1.9 μM, respectively [1]. 2-chloroadenosine (25 μM) increased activity of platelet adenylate cyclase to about 150–160% of the control value. Higher concentrations of 2-chloroadenosine showed less effect above 100 μM [3].

In vivo: In the rat with delayed ischaemic damage, Iterative focal injections of 2-chloroadenosine protected against selective hippocampal CA1 loss [4].
