N6-Cyclopentyladenosine (CPA) is a selective agonist of the adenosine A1 receptor and can be used to mimic the action of the adenosine A1 receptor, with Ki's of 2.3 nM, 790 nM, and 43 nM for human A1, A2A, and A3 receptors, respectively.N6-Cyclopentyladenosine (CPA) can be used to modulate cellular signaling and neurotransmission and other biological processes. Cyclopentyladenosine (CPA) is used to regulate cell signaling, neurotransmitter release and other biological processes.

CCPA (2-chloro-N(6)cyclopentyladenosine) is a potent and selective agonist of adenosine A1 receptor
