초록

Microglial activation has been associated with neurodegenerative diseases by inducing the neuroinflammatory mediators such as nitric oxide (NO), TNF-alpha and IL-1 beta. (-)-Nyasol, a norlignan isolated from a medicinal plant Anemarrhena asphodeloides, showed anti-inflammatory potential in lipopolysaccharide (LPS)-activated BV-2 microglial cells. (-)-Nyasol inhibited the production of NO and prostaglandin E-2 (PGE(2)) and also the expression of inducible nitric oxide synthase and cyclooxygenase-2, which are responsible for the respective production of NO and PGE(2). It also suppressed the mRNA levels of TNF-alpha and IL-1 beta in activated microglial cells. These effects of (-)-nyasol were correlated with the inactivation of p38 MAPK and the suppression of LPS-induced I-kappa B alpha degradation. Taken together, these results suggest that (-)-nyasol can be a modulator in neuroinflammatory conditions induced by microglial activation.
