摘要

The degenerative process of the nigral dopamine(DA)rgic neurons in Parkinson's disease (PD) involves both oxidative stress and neuroinflammation. In the present study, we aimed at developing a novel antioxidant and anti-inflammatory agent for PD therapy. Toward this end, we screened a novel focused library of isothiocyanate derivatives that we have generated for an anti-inflammatory property. We obtained a novel compound ITC-57 and found that ITC-57 effectively induced gene expression of the antioxidant enzymes NAD(P)H quinone oxidoreductase-1, the catalytic and modulatory subunits of glutamylcysteine ligase, and HO-1 in DAergic neuronal CATH.a cells and protected CATH.a cells from oxidative damages. The compound also induced the same antioxidant enzymes in microglial BV-2 cells and suppressed the production of the proinflammatory molecules nitric oxide, interleukin-1 (IL-1) and tumor necrosis factor- (TNF-) in lipopolysaccharide-activated BV-2 cells. In the 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP)-elicited mouse model of PD, ITC-57 protected the DAergic neurons from degeneration, induced HO-1, lowered TNF-, and suppressed microglial activation in the nigra. Furthermore, ITC-57 prevented the PD-associated motor deficits from occurring. Taken together, ITC-57 would be useful toward development of a disease-modifying therapy for PD.
