Fig. 8. Compound 14 activated Nrf2/HO-1 signaling pathway. (A–C) The expressions of Nrf2 and HO-1 were determined by Western blot analysis and the quantification of protein expression was performed by Image J. (D) The inhibitory effect of 14 (16 μM) on the nuclear translocation of Nrf2 induced by LPS via confocal laser scanning microscopy. RAW264.7 cells stained for Nrf2 (red) and nuclei (DAPI, blue) (scale bar: 10 μm). The values are presented as mean ± SD of three independent experiments, n 3. ###p <0.001, vs. the control group; **p <0.01, ***p <0.001, vs. LPS-treated group.
