Parstatin(mouse), a cell-penetrating PAR-1 thrombin receptor agonist peptide, is a potent inhibitor of angiogenesis.

Parstatin(human), a cell-penetrating PAR-1 thrombin receptor agonist peptide, is a potent inhibitor of angiogenesis.

Protease-Activated Receptor-1, PAR-1 Agonist TFA is a selective proteinase-activated receptor1 (PAR-1) agonist peptide. Protease-Activated Receptor-1, PAR-1 Agonist TFA corresponds to PAR1 tethered ligand and which can selectively mimic theactions of thrombin via this receptor.

Parstatin(human) TFA, a cell-penetrating PAR-1 thrombin receptor agonist peptide, is a potent inhibitor of angiogenesis.

Parstatin(mouse) TFA, a cell-penetrating PAR-1 thrombin receptor agonist peptide, is a potent inhibitor of angiogenesis.

FR171113 is a specific and non-peptide thrombin receptor antagonist. FR171113 exhibits the antithrombotic effects of a PAR1 antagonist. FR171113 inhibits thrombin-induced platelet aggregation with an IC50 of 0.29 μM..

SCH79797 is a highly potent, selective nonpeptide protease activated receptor 1 (PAR1) antagonist. SCH79797 inhibits binding of a high-affinity thrombin receptor-activating peptide to PAR1 with an IC50 of 70 nM and a Ki of 35 nM. SCH79797 inhibits thrombin-induced platelet aggregation with an IC50 of 3 μM. SCH79797 has antiproliferative and pro-apoptotic effects, and limits myocardial ischemia/reperfusion injury in rat hearts. SCH79797 also potently prevents PAR1 activation in vascular smooth muscle cells, endothelial cells, and astrocytes.

ENMD-1068 is a novel selective PAR2 antagonist without inhibitory activity against thrombin-mediated PAR3 and PAR4 signaling; blocks TNFα production in synovial explants from patients with arthritis, and inhibits mast cell tryptase-induced recruitment of eosinophils into the pleural cavity of mice, dose dependently attenuates joint inflammation.

I-287 is a potent, selective, orally active inhibitor of PAR2, negative PAR2 allosteric modulator, inhibits PAR2-mediated activation of Gq and G12/13 but not Gi/o proteins (IC50=45-390 nM); I-287 is a negative allosteric modulator (NAM) and not an orthosteric competitive antagonist of hPAR2. I-287 inhibits PAR2-mediated activation of DAG/Ca2+/PKC and RhoA/SRF-RE, as well as FAK and ERK1/2 signaling pathways, shows no effect on PAR2-mediated recruitment of βarrestin2 and receptor internalization. I-287 inhibits PAR2-induced secretion of IL-8 cytokine in vitro and reduces Freund's adjuvant (CFA)-induced paw edema model in mice.

PAR2 antagonist C391 (C391) is a selective PAR2 antagonist, potently inhibits peptidomimetic-induced PAR2 Ca2+ signalling with IC50 of 1.3 uM.C391 blocks both PAR2 Ca2+ and MAPK signalling pathways activated by peptidomimetics and/or proteinase activation.C391 effectively attenuated compound 48/80-induced thermal hyperalgesia in vivo.C391 blocked A. alternata-induced, PAR2-dependent Ca2+ and MAPK signalling in 16HBE14o- cells, as well as β-arrestin recruitment in HEK 293 cells.C391 effectively attenuated A. alternata-induced inflammation, mucus production, mucus cell hyperplasia and airway hyperresponsiveness in acute allergen-challenged murine models.

BMS-98614 is an orally active, selective thrombin receptor protease-activated receptor-4 (PAR-4) antagonist with an IC50 value of 0.4 nM. BMS-98614 has excellent antithrombotic effect.

1-Piperidine Propionic Acid (1-PPA) is an allosteric Inhibitor of protease activated receptor-2 (PAR2) with IC50 of 2.3 uM.

NRD-21 is a potent, selective, reversible, negative allosteric modulator of PAR1 with IC50 of 0.37 uM in calcium mobilization assays.

TFLLRN-NH2 is a potent, PAR1-selective agonist peptide with EC50 of 1.9 uM.
