Protease activated receptors (PARs) are a distinctive four-member family of seven transmembrane G protein-coupled receptors (GPCRs) widely expressed in inflammatory cells. PARs are cleaved by certain serine proteases to expose a tethered ligand domain, this ligand domain then binds to and activates the receptors to initiate multiple signalling cascades. These PAR-activating proteases therefore represent PAR agonists. This PAR-2 agonist peptide mimics the sequence of the “tethered ligand” and is therefore capable of activating the receptor independently of N-terminal proteolysis.

SLIGRL-NH2 inhibits the development of airway eosinophilia, hyper-responsiveness and displays bronchodilator activity in allergic mice and also facilitates gastrointestinal transit in mice in vivo.

PAR activation has been linked to inflammation, therefore compounds that mimic or interfere with the PAR-activating processes are attractive therapeutic candidates.
