Neustadt, Bernard R. published the artcilePotent, selective, and orally active adenosine A2A receptor antagonists: Arylpiperazine derivatives of pyrazolo[4,3-e]-1,2,4-triazolo[1,5-c]pyrimidines, Formula: C25H29N9O3, the publication is Bioorganic & Medicinal Chemistry Letters (2007), 17(5), 1376-1380, database is CAplus and MEDLINE.
Antagonism of the adenosine A2A receptor offers great promise in the treatment of Parkinson’s disease. Employing the known pyrazolo[4,3-e]-1,2,4-triazolo[1,5-c]pyrimidine A2A antagonist SCH 58261 as a starting point, we identified the potent and selective (vs. A1) antagonist 11h (I), orally active in the rat haloperidol-induced catalepsy model. We further optimized this lead to the methoxyethoxyethyl ether 12a (SCH 420814), which shows broad selectivity, good pharmacokinetic properties, and excellent in vivo activity.
