Amino Acid Sequence

Phe-Ser-Leu-Leu-Arg-Tyr-NH2 trifluoroacetate salt

Applicazioni

FSLLRY-NH2 trifluoroacetate salt has been used as a protease-activated receptor 2 (PAR2) inhibitor to test its effects on urinary tract infections (UTIs) in a murine model. It has also been used to study the clinical itch datasets from phase 3 clinical trials for moderate-to-severe AD in atopic dermatitis (AD)-associated acute itch flare mice modelin rats.

Azioni biochim/fisiol

FSLLRY-NH2 is a peptide antagonist of the protease activated receptor 2 (PAR2). The peptide blocks agonist induced itching in rodent models. In cell based assays, the peptide inhibits agonist-induced cardiocyte remodeling, and production of cytokines by endothelial cells.
The ability of FSLLRY-NH2 to decrease visceral hypersensitivity (VH) suggests that PAR2 is involved in the maintenance of VH.

Itch is an evolutionarily conserved sensation that facilitates expulsion of pathogens and noxious stimuli from the skin. However, in organ failure, cancer, and chronic inflammatory disorders such as atopic dermatitis (AD), itch becomes chronic, intractable, and debilitating. In addition to
