What is ARA-290?

ARA-290 (Cibinetide) is an 11-amino acid synthetic peptide derived from the helix B surface peptide (HBSP) of erythropoietin (EPO). Unlike EPO itself, ARA-290 selectively activates the innate repair receptor (IRR) — a heterodimeric complex of the EPO receptor and the beta common receptor (βcR) — without engaging the classical homodimeric EPO receptor responsible for erythropoiesis. This separation of tissue-protective signalling from haematopoietic activity makes ARA-290 a focused research tool for studying EPO’s non-erythroid cytoprotective and anti-inflammatory properties.

Research Applications

Mechanism of Action

ARA-290 binds the IRR (a heterodimer of EPO receptor subunit + βcR subunit), triggering a distinct intracellular signalling cascade from classical EPO. Downstream activates PI3K/Akt (cell survival), JAK2/STAT3 (anti-apoptotic gene expression), and MAPK/ERK (cell proliferation) pathways. Critically, does not activate the EPOR homodimer, so does not stimulate erythropoiesis, haemoglobin synthesis, or platelet aggregation risk associated with exogenous EPO administration.

Key Research Data

Phase 2 RCT (Sarcoidosis SFN) N=55; ARA-290 4mg SC × 28 days vs placebo. Primary endpoint: corneal nerve fibre density (CNFD). Result: significant CNFD preservation + pain NRS reduction (p<0.05)
Pancreatic islet study Human islets treated with IL-1β + IFN-γ; ARA-290 rescued GSIS, reduced apoptosis markers (caspase-3), reduced TNF-α secretion
Rodent ischaemia model ARA-290 SC pre-treatment reduced renal tubular injury scores 40-60% vs vehicle in I/R models (rat)
Selectivity vs EPO No haematopoietic effect confirmed across multiple studies: haematocrit, haemoglobin, reticulocyte count unchanged at research doses

Frequently Asked Questions

How do I reconstitute this peptide?
Add 1–2mL bacteriostatic water to the lyophilized vial by directing water down the inner wall of the vial. Swirl gently until the powder fully dissolves — do not shake or vortex. The solution should be clear and colourless. Use immediately or refrigerate at 2–8°C.
How should this peptide be stored?
Store lyophilized peptide vials at −20°C for long-term storage. Once reconstituted, store at 2–8°C (refrigerator) and use within 21–28 days. Avoid repeated freeze-thaw cycles, direct light, and heat exposure.
What purity is this QSC compound and how is it verified?
All QSC compounds are tested to ≥99% purity by HPLC peak area analysis on every production batch. Molecular identity is confirmed by mass spectrometry. A Certificate of Analysis (COA) is published on the product page and independently verifiable at verify.janoshik.com using the batch reference number.
