体内研究:
GB83 (5 μg; i.p.) reverses neutrophil elastase‐induced synovitis and pain in PAR2 KO mice.Animal Model:8-14 weeks, 20-30 g male C57Bl/6 mice (PAR2 KO mice)
Dosage:5 μg
Administration:I.p.; 3 times at 10?min before and 110 and 230?min after neutrophil elastase administered
Result:Significantly blocked the neutrophil elastase induced increase in vascular perfusion, as well as the number of rolling adherent leukocytes, and also significantly attenuated hindpaw allodynia.

体外研究:
