Unique pharmacological property of ISRIB in inhibition of Aß-induced neuronal cell death.

ABSTRACT

A pharmacological approach to ameliorate Alzheimer's disease (AD) has not yet been established. In the present study, we investigated the pharmacological characteristics of the recently identified memory-enhancing compound, ISRIB for the amelioration of AD. ISRIB potently attenuated amyloid ß-induced neuronal cell death at concentrations of 12.5-25 nM, but did not inhibit amyloid ß production in the HEK293T cell line expressing the amyloid precursor protein (APP). These results suggest that ISRIB possesses the unique pharmacological property of attenuating amyloid ß-induced neuronal cell death without affecting amyloid ß production.
