N6-Cyclopentyladenosine (CPA) is a selective agonist of the adenosine A1 receptor, mimicking its action with Ki values of 2.3 nM, 790 nM, and 43 nM for human A1, A2A, and A3 receptors, respectively. CPA is used to modulate cellular signaling, neurotransmission, and other biological processes.

Carboxypeptidase A1 (CPA1) is secreted as a pancreatic peptidase that comes from the precursor form of inactive procarboxypeptidase. CPA1 comprises a signal peptide, a pro region and a mature chain, and can be activated after cleavage of the pro peptide. It has a free C-terminal carboxyl group, with the preference of residues with aromatic or branched aliphatic side chains. CPA1 cleaves the C-terminal amide or ester bond of peptides and involves in zymogen inhibition. Three different forms of human pancreatic procarboxypeptidase A have been isolated. In contrast to procarboxypeptidase B which was always secreted by the pancreas as a monomer, procarboxypeptidase A occurs as a monomer and/or associated to one or two functionally different proteins, such as zymogen E.
