Stimulation of A1 adenosine receptors in the kidney reduces glomerular filtration rate (GFR) via tubuloglomerular feedback and increases sodium reabsorption. Blocking A1 adenosine receptors would therefore maintain GFR and cause natriuresis. Tonapofylline is a xanthine derivative that binds with high affinity to A1 adenosine receptors from several species including human and acts as a competitive antagonist at these receptors.
