Immunopharmacology Ligand
Compound class: Peptide or derivative
Comment: Cibinetide (ARA 290) is an engineered peptide that mimics the 3 dimensional structure of the helix B surface domain of erythropoietin (EPO). It is designed to bind selectively to the non-hematopoietic EPO receptor (sometimes referred to as the innate repair receptor or IRR), that is believed to be a heterodimer of EPOR and the cytokine family beta common receptor (βCR, CD131) [1-2]. Non-hematopoietic EPO ligands have potential tissue protective and anti-inflammatory actions [4-6,8-10]. The IRR is suggested to be a point of integration between the immune system and pain signalling (via nociception) [11].
Cibinetide is SEQ ID NO. 282 (and peptide ID) as claimed in patent WO2009094172 [3].

2D Structure

An image of the ligand's 2D structure. For small molecules with SMILES these are drawn using the NCI/CADD Chemical Identifier Resolver. Click on the image to access the chemical structure search tool with the ligand pre-loaded in the structure editor. For other types of ligands, e.g. longer nucleotides and peptides, a manually drawn representation of the molecule may be provided.

SMILES / InChI / InChIKey

SMILES (Simplified Molecular Input Line Entry Specification) A specification for unambiguously describing the structure of chemical molecules using short ASCII strings. Canonical SMILES specify a unique representation of the 2D structure without chiral or isotopic specifications. Isomeric SMILES include chiral specification and isotopes.

Standard InChI (IUPAC International Chemical Identifier) and InChIKey InChI is a non-proprietary, standard, textual identifier for chemical substances designed to facilitate linking of information and database searching. An InChIKey is a simplified version of a full InChI, designed for easier web searching.
