ChEBI: CGP-42112A is a hexapeptide consisting of L-tyrosine, L-lysine, L-histidine, L-proline and L-isoleucine amino acid residues coupled in sequence and in which the amino group of the L-tyrosyl residue is substituted by a (pyridin-3-ylcarbonyl)nitrilo group and in which the L-lysyl side chain amino group is substituted by a {N(2)-[(benzyloxy)carbonyl]-L-arginyl}nitrilo group. It is a potent angiotensin II receptor type 2 (AT2 receptor) agonist. It has a role as an angiotensin receptor agonist, a vasodilator agent, an antineoplastic agent, an anti-inflammatory agent and a neuroprotective agent. It is an oligopeptide, a benzyl ester and a pyridinecarboxamide.
