How to use

In Vitro:

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.

In Vivo:

SCH-442416 (0.017 mg/kg; i.p.) completely abrogates the CGS-21680-induced decrease in skeletal muscle injury. SCH-442416 (1 μM•2μL; i.v.) increases the GS and GLAST protein expression in rats. SCH442416 (1 μM) significantly attenuates the adenosine-induced dilation (from 15.3 to 5.6 μm).
