Description
ARA-290 (cibinetide) is a synthetic 11-amino-acid research peptide derived from the helix B region of erythropoietin. It is supplied as a high-purity lyophilized powder for laboratory use only.
The compound is typically described as an N-terminally pyroglutamate-modified analog with the sequence Pyr-Glu-Gln-Leu-Glu-Arg-Ala-Leu-Asn-Ser-Ser. Reported specifications commonly include a molecular weight of approximately 1257 g/mol and a molecular formula of C₅₁H₈₄N₁₆O₂₁. Identity and purity are confirmed by HPLC and mass spectrometry.
In laboratory and preclinical research, ARA-290 has been investigated for effects on innate repair receptor (EPOR/βcR) signaling, including studies related to tissue-protective, anti-inflammatory, and small-fiber neuropathy models in experimental systems. These findings are limited to research settings and do not establish approved medical use.
