Hodgson, Robert A. published the artcileCharacterization of the potent and highly selective A2A receptor antagonists preladenant and SCH 412348 [7-[2-[4-2,4-difluorophenyl]-1-piperazinyl]ethyl]-2-(2-furanyl)-7H-pyrazolo[4,3-e][1,2,4]triazolo[1,5-c]pyrimidin-5-amine] in rodent models of movement disorders and depression, Name: 2-(Furan-2-yl)-7-(2-(4-(4-(2-methoxyethoxy)phenyl)piperazin-1-yl)ethyl)-7H-pyrazolo[4,3-e][1,2,4]triazolo[1,5-c]pyrimidin-5-amine, the publication is Journal of Pharmacology and Experimental Therapeutics (2009), 330(1), 294-303, database is CAplus and MEDLINE.
The adenosine A2A receptor has been implicated in the underlying biol. of various neurol. and psychiatric disorders, including Parkinson’s disease (PD) and depression. Preladenant and SCH 412348 [7-[2-[4-2,4-difluorophenyl]-1-piperazinyl]ethyl]-2-(2-furanyl)-7H-pyrazolo[4,3-e][1,2,4]triazolo[1,5-c]pyrimidin-5-amine] are potent competitive antagonists of the human A2A receptor (Ki = 1.1 and 0.6 nM, resp.) and have > 1000-fold selectivity over all other adenosine receptors, making these compounds the most selective A2A receptor antagonists reported to date. Both compounds attenuate hypolocomotion induced by the A2A receptor agonist CGS-21680 [2-[p-(2-carboxyethyl)phenethylamino]-5′-N-ethylcarboxamidoadenosine], suggesting that they inhibit A2A receptor activity in vivo. Their high degree of selectivity and robust in vivo activity make preladenant and SCH 412348 useful tools to investigate the role of the A2A receptor system in animal models of PD and depression. Oral administration of preladenant and SCH 412348 (0.1-1 mg/kg) to rats potentiated 3,4-dihydroxy-
