ARA-290

An erythropoietin-derived 11-amino-acid peptide examined in laboratory tissue-protective research.

ARA-290 (also called cibinetide) is an 11-amino-acid peptide whose sequence is derived from the helix-B region of erythropoietin. In the published literature it appears predominantly in tissue-protective and innate-repair research models associated with the so-called innate repair receptor. Describing it as "studied in" these areas reflects where scientific attention has gone, not a claim that it produces any effect. This content is background about the molecule and is not medical guidance or intended for human use.

Classification and structure

ARA-290 is classified as a synthetic peptide fragment. Its sequence corresponds to a surface region of erythropoietin that has been separated from the protein's erythropoietic activity, making it of interest to researchers studying non-hematopoietic signaling. It is handled in the laboratory as a defined peptide research compound.

Areas of research

ARA-290 appears in a few defined areas of the research literature.

• Tissue-protective models — Investigated in research examining cellular stress and tissue-protective pathways.
• Innate repair receptor — Appears in the literature on non-hematopoietic erythropoietin signaling.
• Neuropathic research — Has been the subject of research examining small-fiber and sensory-nerve models.

As always in this library, describing a compound as “studied in” an area is a statement about where scientific attention has gone — not a claim that it produces any result in humans or animals.
