Protective Effect of T-588 on Toxic Damage by Serum Deprivation and Amyloid-β Protein in Cultured Neurons

Abstract

The present study examines the effect of the cognition enhancer (1R)-1-benzo[b]thiophen-5-yl-2-[2-(diethylamino)ethoxy]ethan-1-ol hydrochloride (T-588) on neuronal injury induced by serum deprivation or amyloid-β protein (Aβ). T-588 protected partially against neuronal injury induced by serum deprivation or Aβ in cultured cortical neurons. T-588 did not affect the phosphorylation of extracellular signal-regulated kinase (ERK) in cortical neurons and SH-SY5Y cells. These results suggest that T-588 has a protective effect in neuronal injury models and the effect is not mediated by an ERK signal pathway.
