Nine undescribed compounds and seven known compounds were isolated from the husks of Xanthoceras sorbifolia. Three of them showed significant inhibition on NO productions and controlled the NF-kappa B signaling pathway, suggesting their potential for the prevention of inflammation-related neurodegenerative disorders.
The husks of Xanthoceras sorbifolia Bunge were explored resulting in the isolation of nine undescribed compounds and seven known compounds. Their structures were defined by NMR spectroscopic techniques, HRESIMS ana-lyses and DP4+ possibility analysis. Three of them showed evident inhibition on NO productions in LPS-induced BV-2 cells by controlling the expression of the nuclear factor-kappa-B (NF-kappa B) signaling pathway. Furthermore, they also markedly decreased the expression of the proteins COX-2 and iNOS. In addition, most compounds showed no cytotoxicity against Hep 3B, A549, HCT 116, AGS, MCF-7 cell lines. These findings showed that the husks of X. sorbifolia might have considerable potential for the prevention of inflammation-related neurode-generative disorders.
