2-Chloro-N⁶-cyclopentyladenosine (CCPA) is a specific receptor agonist for the Adenosine A1 receptor.^[1] It is similar to N⁶-cyclopentyladenosine. Due to CCPA's high affinity for Adenosine A1 receptors, its tritiated derivative [³H]CCPA can be used as a diagnostic tool for detecting the receptors in tissue with low receptor density.
