体外研究 | Sophoricoside is an isoflavone glycoside isolated from Sophora japonica and has anti-inflammatory, anti-cancer and immunosuppressive effects. The results show that Sophoricoside (50 μM) significantly inhibits the PMACI-induced histamine release. The inhibition rate reaches up to 30.24%. The maximal rates of TNF-α, IL-8 and IL-6 inhibition by Sophoricoside (50 μM) are approximately 31.42%, 43.43% and 34.24%, respectively. The rates of the levels of Rel/p65 inhibition in nuclear by Sophoricoside (50 μM) is approximately 50.14%. Results show that the enhanced caspase-1 activity induced by PMACI is significantly reduced by Sophoricoside in a dose-dependent manner. |
体内研究 | When the Sophoricoside is orally administered 1 h before compound 48/80 injections, the scratching behaviors is reduced. The inhibition rate of Sophoricoside (2 mg/kg) is approximately 41.21%. Orally administered Sophoricoside inhibits the scratching behaviors by 47.31%. When mice are treated for 2 weeks with Sophoricoside, the atopic dermatitis is recovered to a significant extent. |
