  Potent and selective adenosine A2A receptor antagonists: [1,2,4]-triazolo[4,3-c]pyrimidin-3-ones

  摘要：

  Antagonism of the adenosine A(2A) receptor affords a possible treatment of Parkinson's disease. In the course of investigating pyrazolo[4,3-e]-1,2,4-triazolo[1,5-c]pyrimidine A(2A) antagonists, we prepared [1,2,4]-triazolo[4,3-c]pyrimidin-3-ones with potent and selective (vs A(1)) A(2A) antagonist activity. Structure-activity relationships are described for this series. (C) 2011 Elsevier Ltd. All rights reserved.

  Compounds of the Formula I wherein R 1 and R 2 together with the carbon atoms to which they are bonded optionally form a further heteroaromatic ring of the formula (II) as well as pharmaceutically acceptable salts, solvates, esters and prodrugs thereof are adenosine A2a receptor antagonists and, therefore, are useful in the treatment of central nervous system diseases, in particular Parkinson's disease.
