Background

Tonapofylline (BG 9928) is an orally active and selective adenosine A1 receptor antagonist with a Ki of 7.4 nM for human adenosine A1 receptor (hA1), which displays 915-fold selectivity versus human adenosine A2A receptor and 12-fold selectivity versus human adenosine A2B receptor and is used in development for the treatment of heart failure[1][2]. Ki: 7.4 nM (Human adenosine A1 receptor)[1]

Tonapofylline (BG 9928) (1 mg/kg; p.o., b.i.d, days 0-6) produces sustained reductions in post-Cisplatin serum creatinine and blood urea nitrogen levels, improves body weight recovery and significant attenuation of Cisplatin-induced (5.5 mg/kg) kidney pathology scores[3]. Animal Model: Female viral antigen-free Sprague-Dawley rats[3]
