Excessive release of proinflammatory cytokines by activated microglia can cause neurotoxicity in neurodegenerative diseases. We found that Brevicompanine E (BE), isolated from a deep ocean sediment derived fungus Penicillium sp., inhibited lipopolysaccharide (LPS)-induced tumor necrosis factor-α (TNF-α), interleukin-1β (IL-1β), inducible nitric oxide (iNOS) and cyclooxygenase-2 (COX-2) production in microglia. Moreover, electrophoretic mobility shift assay (EMSA) demonstrated that BE attenuated nuclear factor-κB (NF-κB) and activator protein-1 (AP-1) DNA binding activity in LPS-induced microglia. Consistent with this finding, BE inhibited LPS-induced IκBα degradation, NF-κB nuclear translocation, and also Akt, c-Jun NH2-terminal kinase (JNK) phosphorylation. Thus, BE may be potentially useful for modulating neuroinflammation.
