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.
Partial adenosine receptor A1 and cAMP-biased A2B agonist with in vivo cardioprotection efficacy without the risk of a full atrioventricular block.
