PDB Ligand Immunopharmacology Ligand
Compound class: Synthetic organic
Comment: AZ3451 is a negative allosteric modulator of protease-activated receptor 2 (PAR2) that prevents receptor activation and signalling [1]. Substantial evidence indicates that PARs are involved in inflammatory disease, with roles in causing inflammatory reactions in peripheral limb tissue, and modulating arthritic joint inflammation and pain.
