Abstract
Protease‐activated receptor 2 (PAR‐2) is an important target for drug discovery in the pharmaceutical and cosmetic industries. Although many peptide agonists have been developed, they are active at micromolar concentrations or are metabolically unstable. In this study, we designed novel peptide agonists by peptoid technology and synthesized them by standard Fmoc SPPS (Solid Phase Peptide Synthesis) procedures. One of them, Furo‐LIGK‐nV‐NH2, showed very good agonist activity at nanomolar concentrations and showed markedly increased stability in rat plasma compared to that of the control agonist.
