The enzyme phosphodiesterase 10A (PDE10A) regulates the activity of striatal, medium spiny neurons (MSNs), which are divided into a behaviorally stimulating, Gs-coupled D1 receptor-expressing "direct" pathway and a behaviorally suppressant, Gi-coupled D2 receptor-expressing "indirect" pathway. Activating both pathways, PDE10A inhibitors (PDE10AIs) combine(More)
Gastrin delays gastric emptying of liquids probably by reducing gastric tone. The mechanism responsible for the relaxatory effect induced by pentagastrin was unknown. The aim of this study was to investigate the effects of pentagastrin and the underlying mechanisms responsible for these effects. Could nitric oxide (NO) be involved as a mediator. Gastric(More)
Adenosine A2A antagonists are believed to have therapeutic potential in the treatment of Parkinson's disease (PD). We have characterized the dual adenosine A2A/A1 receptor antagonist JNJ-40255293 (2-amino-8-[2-(4-morpholinyl)ethoxy]-4-phenyl-5H-indeno[1,2-d]pyrimidin-5-one). JNJ-40255293 was a high-affinity (7.5 nM) antagonist at the human A2A receptor with(More)
