Abstract

Fourteen benzofuran compounds were identified in the fruits of Psoralea corylifolia L., with four previously undescribed compounds (4, 9-11) being discovered. Their chemical structures were definitively determined through comprehensive spectral data analysis. The compounds were investigated for their antioxidant, anti-tumor, and anti-inflammatory properties, revealing that benzofuran compounds exhibit significant anti-inflammatory effects. Compound 2 demonstrated the most potent anti-inflammatory effect, surpassing that of the positive control drug. The potential anti-inflammatory mechanism of 2 was extensively explored through network pharmacology research. Subsequent validation of the selected targets via Western blot analysis confirmed that 2 exerts its anti-inflammatory effects by activating the TLR4/NF-κB pathway. These findings offer a novel perspective on the development of benzofuran glycoside compounds and Psoralea fructus.
