  Rapid Multistep Synthesis of 1,2,4-Oxadiazoles in a Single Continuous Microreactor Sequence

  摘要：

  A general method for the synthesis of bis-substituted 1,2,4-oxadiazoles from readily available aryinitriles and activated carbonyls in a single continuous microreactor sequence is described. The synthesis incorporates three sequential microreactors to produce 1,2,4-oxadiazoles in similar to 30 min in quantities (40-80 mg) sufficient for full characterization and rapid library supply.

  In this study, a series of compounds with 1,2,4-oxadiazole core was designed and synthesized for the optimi-zation of JC01, an anti-inflammatory hit identified from our in-house compound library using NF-xB pathway luciferase assay and NO production assay. All the synthetic compounds 1-29 have been screened for their anti-inflammatory effects by evaluating their inhibition against LPS-induced NO release, and compound 17 exhibited the highest activity. Western blotting and immunofluorescence analysis revealed that 17 prominently inhibited LPS-induced activation of NF-kappa B in RAW264.7 cells and blocked the phosphorylation of p65. Consistent with these results, it was found that 17 prevented the nuclear translocation of NF-kappa B induced by LPS. These data highlighted 17 as a promising anti-inflammatory agent by inhibiting NF-kappa B activity.
