Abstract

Acanthoic acid (AA) is a pimaradiene diterpene isolated from the Korean medicinal plant, Acanthopanax koreanum (Araliaceae), which has been traditionally used as a tonic and sedative as well as in the treatment of rheumatism and diabetes in korea. Proteinase-activated receptor-2 (PAR-2) agonist trypsin plays a role in inflammation, and human leukemic mast cells (HMC-l) express PAR-2. In the present study, the effect of acanthoic acid on production of tumor necrosis factor-${\alpha}$ (TNF-${\alpha}$) and tryptase in trypsin-stimulated HMC-1 was examined. (omitted)
