Research Compound Database

Also: Cibinetide, ARA 290, Erythropoietin Mimetic Peptide

ARA-290 is an engineered peptide derived from erythropoietin that selectively activates the tissue-protective receptor complex without stimulating red blood cell production. It is primarily researched for neuropathic pain relief, nerve repair, inflammation reduction, and metabolic support in conditions like sarcoidosis and type 2 diabetes.

Also: Lys-Pro-Val, Alpha-MSH C-terminus tripeptide

KPV is a naturally occurring tripeptide (Lysine-Proline-Valine) derived from the C-terminus of alpha-MSH. It is one of the most potent anti-inflammatory peptides identified, with documented effects on gut inflammation, skin conditions, and systemic immune modulation. Its small size allows it to penetrate gut epithelium and cross the blood-brain barrier.

Also: PNC27, p53-Derived Peptide, Antitumor Peptide PNC-27

PNC-27 is an experimental anti-cancer peptide derived from the p53 tumor suppressor protein. It is designed to selectively target and kill cancer cells by exploiting the aberrant membrane expression of HDM-2 (the p53-binding protein) that is found on the surface of cancer cells but not normal cells. Research is entirely preclinical — no human trials completed.

Also: Tα1, Zadaxin, Thymalfasin

Thymosin Alpha-1 is a naturally occurring 28-amino acid peptide that acts as a potent immune modulator. It is the first thymic peptide to receive regulatory approval (in over 30 countries) for treatment of Hepatitis B and as an immune adjuvant. It enhances both innate and adaptive immunity.

Also: TB4-Frag, Ac-SDKP, N-Acetyl-Seryl-Aspartyl-Lysyl-Proline

The TB-4 fragment (Ac-SDKP) is the active anti-fibrotic and cardioprotective component of Thymosin Beta-4. While full TB-500 handles actin sequestration and cell motility, Ac-SDKP specifically inhibits TGF-β-driven fibrosis and inflammation. It naturally circulates in blood and is regulated by ACE (angiotensin-converting enzyme).

Also: Vasoactive Intestinal Peptide, VIP-28

VIP (Vasoactive Intestinal Peptide) is a 28-amino acid neuropeptide with potent anti-inflammatory, vasodilatory, and immunomodulatory properties. It is naturally produced throughout the body and plays a critical role in regulating the autonomic nervous system, gut motility, immune tolerance, and circadian rhythm. Research interest has surged due to its potential in treating Long COVID, MCAS, dysautonomia, and autoimmune conditions.

Also: Lys-Glu, KE Peptide, Dipeptide KE

Vilon is a dipeptide immunomodulatory bioregulator that is one of the simplest peptides in the Khavinson series. Despite its tiny size (just two amino acids), it demonstrates significant immune regulatory, anti-aging, and gene-regulatory effects. Used in longevity protocols for immune system restoration and as part of comprehensive Khavinson peptide stacks.
