Fig. 6From: Further structure–activity relationships study of substituted dithiolethiones as glutathione-inducing neuroprotective agentsNeuroprotection of 6a against 6-OH induced neurotoxicity. SH-SY5Y cells were treated for 24 h with various concentrations of 6a, followed by co-treatment with 6-OHDA (40 μM) for a further 24 h, at which time cellular viability was assed. Data shown are mean ± SEM of at least three different experiments. *P < 0.05Back to article page
