Adenosine A1 receptor activator T62 is an allosteric enhancer of adenosine A1 receptor. Adenosine A1 receptor activator T62 produces antinociception in animal models of acute pain and also reduces hypersensitivity in models of inflammatory and nerve-injury pain[1][2][3].
Adenosine A1 receptor activator T62 (0.3-3 μg; intrathecal administration; male SpragueDawley rats) treatment produces a dose-dependent antihypersensitivity effect, with no effect on ambulation or activity level[1]. Animal Model: Male SpragueDawley rats (250 g) after paw incision surgery[1]
