About ARA-290

Molecular weight
1257.3 g/mol
CAS number
1208243-50-8

ARA-290 (cibinetide) is a synthetic 11-residue peptide engineered from the helix-B surface domain of erythropoietin (EPO). It is studied as a selective agonist of the innate repair receptor, a complex of the EPO receptor and the beta-common receptor (CD131), engaging tissue-protective signalling without activating the erythropoietic receptor. Its N-terminal residue is a cyclised pyroglutamate.
