ARA-290

ARA-290, also known as cibinetide, is a synthetic 11-amino-acid peptide developed from the three-dimensional structure of erythropoietin and first described in research published in 2008. It has the molecular formula C51H84N16O21, a molecular weight of 1,257.3 g/mol, and is identified by CAS number 1208243-50-8, excluding salt counterions. The peptide is notable for mimicking the exposed surface of erythropoietin’s helix B—a region investigated for tissue-protective signaling separate from red blood cell production. ARA-290 is classified as an erythropoietin-derived peptide mimetic and contains an N-terminal pyroglutamate residue.
