8-ethoxy-9-ethyladenine (ANR 94) had been characterized in vitro as an adenosine receptor antagonist. Its chemical structure had been shown . ANR 94 has shown high selectivity and affinity for the human adenosine A2A receptor subtype and high antiparkinsonian activity in unilaterally 6-hydroxydopamine (6-OHDA)-lesioned rats . The Ki value of ANR 94 to the adenosine A2A receptor is 46 nM . Adenosine is deeply involved in the control of motor behaviour and substantial evidences . In Chinese hamster ovary (CHO) cells stably transfected with human recombinant adenosine receptors, ANR 94 was more selective than ANR 82 at the adenosine A2A receptor, with a Ki value of 46 nM . Treatment with ANR 94 (0.5 mg/kg i.p. for 7 days) significantly prevented 1-methyl-4-phenyl-1, 2, 3, 6-tetrahydropyridine (MPTP)-induced degeneration of TH-positive cells (p < 0.0005) . In rats, at a dose of 5 mg/kg i.p., ANR 94 did not modify spontaneous motility, whereas at higher doses (10 or 15 mg/kg), it induced hypermotility. ANR 94 at a dose of 1 mg/kg had a low efficacy on catalepsy, whereas 5 mg/kg was fully effective. In deeply cataleptic rats, ANR 94 at a dose of 5 mg/kg i.p. during the 90-min testing period significantly reversed the catalepsy induced by 0.2 mg/kg of haloperidol. From 30-60 min, the effect of ANR 94 was maximal. The anticataleptic effect of ANR 94 had a long duration of over 150 min. In 6-OHDA-lesioned rats, ANR 94 significantly increased the number of contralateral rotations induced by l-DOPA (3 mg/kg); this effect lasted up to 120-130 min .
