chemoattractant

Copper tripeptide (GHK-Cu) is a naturally occurring copper complex of the tripeptide glycyl-L-histidyl-L-lysine, with a strong affinity for copper(II). First isolated from human plasma, it is also found in saliva and urine.

H-Pro-Gly-Pro-OH, a collagen-derived matrikine, traditionally acts as a neutrophil chemoattractant, guiding these cells to target locations to orchestrate localized repair responses. Additionally, this compound initiates the transcription of neurotrophins and their receptor genes following cerebral ischemia [1] [2].

C5a Anaphylatoxin (human) is a pro-inflammatory peptide that acts as a leukocyte chemoattractant and is used in research on inflammation and immune responses, including allergic asthma [1] [2].

WRW4-OH is a bioactive peptide that impedes the interaction of the FPRL1 agonist WKYMVm with its designated receptor. As a classical chemoattractant receptor prevalent in phagocytic cells of peripheral blood and brain, FPRL1's activation is integral to inflammatory responses within host defense mechanisms and is implicated in neurodegenerative disorders.

N-Formyl-Nle-Leu-Phe-Nle-Tyr-Lys TFA (For-Nle-Leu-Phe-Nle-Tyr-Lys-OH (TFA)) (For-Nle-Leu-Phe-Nle-Tyr-Lys-OH TFA) is a formyl peptide receptor (FPR) agonist and a potent chemoattractant for human neutrophils, with its radioiodinated form retaining full biological activity.
