N6-Cyclopentyladenosine (CPA) is a drug which acts as a selective adenosine A1 receptor agonist.[1] It has mainly cardiovascular effects with only subtle alterations of behavior.[2] CPA is widely used in scientific research into the adenosine receptors and has been used to derive a large family of derivatives.[3][4][5][6][7]
