SCH442416 is a potent, selective and brain-penetrant antagonist of adenosine A2A receptor (A2AR), with Kis of 0.048 and 0.5 nM for human and rat A2AR respectively. SCH442416 displays more than 23000-fold selectivity over A1R, A2BR, and A3R (Ki=1111, 10000, and 10000 nM, respectively). SCH442416 can be used for imaging of adenosine A2A receptors in rat and primate brain.
体外研究
SCH442416 is selective for A2AR (Ki=0.50 nM) in rat striatal membranes over A1R and A3R (Ki=1815 and >10000, respectively).
SCH442416 (0.1-10 μM) increases the glutamine synthetase (GS) and glutamate aspartate transporter (GLAST) proteins expression of Müller cells in Group 1 μM.
