Selective adenosine A1 receptor antagonist; displays 890-fold selectivity for rat A1 receptors over A2A receptors (Ki values are 0.19 and 170 nM respectively). Displays no effect on recombinant rat A3 receptors expressed on CHO cells at concentrations up to 10 μM. Exhibits diuretic and renal protective effects in rats.

We injected this drug at 1 mg/Kg and 2 mg/Kg systemically (IP) into transgenic mice and monitored the effect on motor behavior. The drug efficiently induced motor symptoms in the transgenic mice at these concentrations.
The drug dissolves well in saline + 0.3% tween 80 with 3X vortex (1min) and sonicate (5min).
