The affinities (K_i) of the drug for the human adenosine receptors are 5.9 nM for the adenosine A_2A receptor, 410 nM for the adenosine A₁ receptor (69-fold lower than for the A_2A receptor), 260 nM for the adenosine A_2B receptor (44-fold lower than for the A_2A receptor), and >10,000 nM for the adenosine A₃ receptor (>1,695-fold lower than for the A_2A receptor).^[2]

Lu AA41063 was first described in the scientific literature by 2014.^[1][5]

Lu AA47070, a water-soluble phosphate ester prodrug of Lu AA41063, is orally active and was under development for the treatment of Parkinson's disease but was discontinued.^{[6][1][2][7][8]} In addition to its antiparkinsonian-like effects, Lu AA47070 reverses motivational deficits in animals and hence shows pro-motivational effects.^[9][10][11]
