Lu AA41063 is a selective adenosine A_2A receptor antagonist. ^{[1] [2] [3] [4] [5]} Structurally, it is a non-xanthine. ^[2]

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]}

PMID   23960840. Antagonists of the A2A subtype of adenosine receptor have emerged as a leading candidate class of nondopaminergic antiparkinsonian agents (Feigin, 2003). The ability of Lu AA47070, adenosine A2A antagonist to reverse the effects of D2 receptor blockade suggests that this compound could have potential utility as a treatment for parkinsonism, and for some of the motivational symptoms of depression. In the adult male Sprague Dawley rats the tremulous jaw movements induced by subchronic administration of the DA D2 antagonist pimozide were reversed by Lu AA47070. Lu AA47070 was also able to reverse the catalepsy induced by subchronic administration of the D2 antagonist pimozide and it also reverse the locomotor suppression induced by subchronic administration of the D2 antagonist pimozide (Collins et al., 2012).
