01Definition
ARA-290 is a regenerative research compound. An erythropoietin-derived peptide studied for innate-repair-receptor signaling. It is also known as Cibinetide.
Sequence · 11-aa EPO helix-B fragment
02Research Mechanism
ARA-290 (cibinetide) is an 11-amino-acid peptide derived from the helix-B region of erythropoietin. It is studied as a selective agonist of the innate repair receptor — a heterocomplex of the EPO receptor and the β-common receptor (CD131) — associated with tissue protection and anti-inflammatory signaling.
