Background

Capadenoson is a selective agonist of Adenosine A1 receptor [1].Adenosine A1 receptor is a member of G-protein coupled receptor 1 family and plays an important role in the fertilization process, kidney function and ethanol intoxication. Many studies have shown that Adenosine A1 receptor is correlated with a variety of diseases, like angina, heart failure, and its agonist is becoming a promising target in clinic [1].Capadenoson is a potent Adenosine A1 receptor agonist and belongs to the non-nucleosidic adenosine receptor family. When tested with perfused rat hearts isolated from Wista and SHR strains, capadenoson combined with CCPA treatment significantly decreased NE release in a dose-dependent manner [1].In dog model with heart failure induced by microembolization, oral administration of capadenoson for 12 weeks improved left ventricular function and prevented progressive remodeling [2]. When pre-treated Wistar rats with capadenoson (0.15 mg/kg) for 5 days, physical restraint for 2 hours increased heart rate [1].When tested with male patients with stable angina, oral administration of capadenoson lowered exercise heart failure at comparable maximum workload [3].
