New discoveries in chemical research and development in 2021. As an important bridge between the micro, chemistry is one of the main methods and means for humans to understand and transform the material world. In an article, author is Zhao, Bo-Bo, once mentioned the application of 372-38-3, Safety of 1,3,5-Trifluorobenzene, category is benzoxazole. Now introduce a scientific discovery about this category.
Benzoxazole and its derivatives have been widely studied in recent years due to their various biological properties. A previous study has demonstrated that K313 (1H-indole-2,3-dione 3-(1,3-benzoxazol-2-ylhydrazone)), a novel benzoxazole derivative, inhibits T cell proliferation to yield immunosuppressive effects. However, there are no related reports about its anti-inflammatory effects. In the present study, we investigated the anti-inflammatory properties and the underlying molecular mechanism of K313 in lipopolysaccharide (LPS)-induced RAW264.7 macrophages. K313 dose-dependently (5, 10, and 20M) inhibited LPS-stimulated nitric oxide (NO), interleukin (IL)-6, tumor necrosis factor (TNF)-, and 3-nitrotyrosine (3-NT) production and significantly decreased the gene transcription levels of inducible nitric oxide (iNOS), IL-6, and TNF-. In addition, the results showed that the inflammatory cytokines suppressed by K313 were not regulated by p65 NF-B, ERK1/2, AKT, or p38 MAPK. Instead, K313 increased phosphorylation of glycogen synthase kinase-3 beta (GSK-3) (Ser9) resulting in GSK-3 deactivation. Moreover, in LPS-stimulated RAW264.7 macrophages, K313 and lithium chloride (LiCl) had a synergistic effect on the anti-inflammatory response. These results indicated that K313 exhibited anti-inflammatory properties and revealed the potential mechanism. K313 can increase GSK-3 (Ser9) phosphorylation to decrease GSK-3 activation in LPS-induced RAW264.7 macrophages.
