Abstract 

Microglial activation plays a pivotal role in the pathogenesis of neurodegenerative diseases by producing various proinflammatory cytokines and nitric oxide (NO). In the present study, the anti-inflammatory and subsequent neuroprotective effects of catechol and its derivatives including 3-methylcatechol, 4-methylcatechol, and 4-tert-butylcatechol were investigated in microglia and neuroblastoma cells in culture. The four catechol compounds showed anti-inflammatory effects with different potency. The catechols significantly decreased lipopolysaccharide (LPS)-induced NO and tumor necrosis factor (TNF)-α production in BV-2 microglia cells. The catechols also inhibited the expression of inducible nitric oxide synthase (iNOS) and TNF-α at mRNA or protein levels in the LPS-stimulated BV-2 cells. In addition, the catechols inhibited LPS-induced nuclear translocation of p65 subunit of nuclear factor (NF)-κB, IκB degradation, and phosphorylation of p38 mitogen-activated protein kinase (MAPK) in BV-2 cells. Moreover, the catechols attenuated the cytotoxicity of LPS-stimulated BV-2 microglia toward co-cultured rat B35 neuroblastoma cells. The catechols, however, did not protect B35 cells against H2O2 toxicity, indicating that the compounds exerted the neuroprotective effect by inhibiting the inflammatory activation of microglia in the co-culture. The anti-inflammatory and neuroprotective properties of the catechols in cultured microglia and neuroblastoma cells suggest a therapeutic potential of these compounds for the treatment of neurodegenerative diseases that are associated with an excessive microglial activation.
