Biochem/physiol Actions

Capadenoson (BAY 68-4986) is an adenosine receptor A1 (A1AR) partial agonist (GTPγS binding EC50/Emax = 0.1 nM/74% vs. 0.3 nM/100% with CCPA; human cortex membranes) that exerts additional biased A2BAR agonism toward cAMP signal transduction (pEC50 = 8.94/cAMP, 6.20/Ca+2, 6.12/pERK, 5.03/IP1), while exhibiting weak A2A & A3 potency. Capadenoson offers cardioprotection efficacy in an ischemia-reperfusion injury rat model in vivo (25/28% infarct size reduction with 0.1/0.3 mg/kg iv.) without the risk of a full atrioventricular (AV) block (isolated perfused rat heart rate = 100% up to 10 nM, 90% at ≥10 μM) seen with the full A1 agonist CCPA.

Adenosine is known to be released under a variety of physiological and pathophysiological conditions to facilitate the protection and regeneration of injured ischemic tissues. The activation of myocardial adenosine A1 receptors (A1 Rs) has been shown to inhibit myocardial pathologies associated

Adenosine, a purine nucleoside, is present in all cells in tightly regulated concentrations. It has many different physiological effects in the whole body and in the heart. Adenosine activates four G protein-coupled receptors A1, A2a, A2b, and A3. Activation of

Cardiac arrest is a leading cause of death in the United States, and, currently, therapeutic hypothermia, now called targeted temperature management (TTM), is the only recent treatment modality proven to increase survival rates and reduce morbidity for this condition. Shivering

The adenosine A2B receptor (A2BAR) has been identified as an important therapeutic target in cardiovascular disease, however in vitro and in vivo targeting has been limited by the paucity of pharmacological tools, particularly potent agonists. Interestingly, 2-((6-amino-3,5-dicyano-4-(4-(cyclopropylmethoxy)phenyl)-2-pyridinyl)thio)acetamide (BAY60-6583), a potent
Samantha L Cooper et al.

Adenosine is a local mediator that regulates physiological and pathological processes via activation of four GPCRs (A1 , A2A , A2B , and A3 ). We have investigated the effect of two A1 -receptor-selective agonists and the novel A1 -receptor
