| Popis: | BJ-1103, as a 6-aminopyridin-3-ol skeletal compound, was originally developed as an antioxidant against free radicals and oxidative stress was prepared from pyridoxine·HCl by the reported procedure. In the present study, we examined the effect of BJ-1103 on neuroprotection and neuroinflammation. Our data showed that BJ-1103 can protect HT22 cells against glutamate-induced cell cytotoxicity. And, BJ-1103 also inhibited LPS-induced inflammatory action. In addition, BJ-1103-induced heme oxygenase-1 (HO-1) expression and elevated HO-1 activities in the two cell lines studied. Additionally, BJ-1103 treatment induced nuclear transcription factor erythroid-2 related factor 2 (Nrf2) and increased the promoter activity of antioxidant response elements (AREs). We have demonstrated using the Nrf2 siRNA, HO inhibitor or HO-1 siRNA that BJ-1103 suppressed neurotoxicity and neuroinflammation through the Nrf2-mediated HO-1 expression. These results demonstrated that BJ-1103 may have good therapeutic agent against neurodegenerative diseases that are induced by oxidative stress and neuroinflammation. |
