PAR2 (1-6) is a synthetic peptide agonist of proteinase-activated receptor 2 (PAR2) that corresponds to residues 1-6 of the amino terminal tethered ligand sequence of mouse and rat PAR2. It also corresponds to residues 39-44 and 37-42 of the mouse and rat full-length sequences, respectively. PAR2 (1-6) induces relaxation in precontracted rat arteries in a concentration-dependent manner, an effect that can be reduced by the nitric oxide synthase inhibitor L-NNA . It inhibits keratinocyte growth in the presence and absence of growth factors. PAR2 (1-6) inhibits LPS-induced pulmonary neutrophil influx and increases in matrix metalloproteinase-2 (MMP-2) activity in mice.

PAR-2 Activating Peptide acetate (SLIGRL-NH2 acetate) is an agonist of Protease-Activated Receptor-2 (PAR-2).

Anti-PAR2 Antibody is a neutralizing monoclonal antibody targeting Protease-activated Receptor 2 (PAR2). By specifically binding to its extracellular domain and interfering with protease-mediated receptor activation, this antibody effectively inhibits downstream inflammatory signaling and nociceptive transmission, and is commonly used in studies of acute/chronic inflammation, neurogenic pain, and dermatological conditions.

AY 77 (Unk-Cha-Chg-NH2) is a potent and selective PAR2 agonist. AY 77 showed selectivity for Ca2+ and ERK1/2 signaling (ec50 value of Ca2+ release was 40 nM and ec50 value of ERK1/2 phosphorylation was 2 μM). AY 77 can promote migration of human breast cancer cells in vitro.

Trypsin is a serine protease that can be isolated from fish to hydrolyze lysine or arginine carboxy-side proteins. With the anti-inflammatory activity, Trypsin could induce the cell membrane fusion of PDCoV-infected cells through the interaction between the S glycoprotein of PDCoV and pAPN, activate PAR2 and PAR4, and promote cell proliferation and differentiation. Trypsin can be used to promote wound healing and study neurogenic inflammation.
