Abstract
ST1535 (2-butyl-9-methyl-8-(2H-1,2,3-triazol 2-yl)-9 H-purin-6-ylamine) is a novel compound showing a preferential adenosine A(2A) receptor antagonist profile. To explore the potential neuroprotective profile of this compound, we evaluated whether ST1535 prevented quinolinic acid (QA)-induced glutamate outflow in the rat striatum (a reliable index of neuroprotective activity in vivo). Microdialysis experiments were performed in naive Wistar rats. In these experiments, a behaviourally active and inactive doses of ST1535 were used. Both doses significantly prevented QA-induced glutamate outflow in the striatum. These results show that ST1535 protects towards striatal excitotoxicity, even though its reduced A(2A)/A(1) selectivity might limit its actual neuroprotective potential.
