藥理研究

• 3-O-(2,3-dimethylbutanoyl)-13-O-decanoylingenol (DBDI)purified from the Euphorbia kansui L., inhibits degranulation in rat basophilic leukemia 2H3 cells upon aggregation of the FcepsilonRI. In the present study, we demonstrated that the DBDI significantly inhibits release of beta-hexosaminidase, synthesis of eicosanoids, and mobilization of intracellular Ca(2+) in the bone marrow-derived mouse mast cells stimulated with IgE and antigen. Furthermore, we revealed that phosphorylation of Syk, phospholipase C-gamma(2), and extracellular signal-related kinase 1/2 is significantly suppressed in the DBDI-treated mast cells. These findings suggest that the DBDI may have a therapeutic potential for allergic diseases by inhibiting intracellular signaling pathways for activation and chemical mediator release in mast cells.
