• Uses: CGS 21680A is a potent, selective agonist of the adenosine A2A receptor (Ki = 11-46 nM). It is less effective at adenosine A1 and A3 receptors (Kis = 0.5-3.1 and 0.6-1 μM, respectively) and is without effect at adenosine A2B (Ki > 10 μM). CGS 21680A is commonly used to study the actions of the adenosine A2A receptor in cells and tissues.[Cayman Chemical] Adenosine receptors are related to many diseases such as cardiovascular, autoimmune, and cancer. CGS 21680 is a potent and selective agonist of the adenosine A2A receptor, a member of G protein coupled receptor (1,2,3).
