Tip60 HAT activators as therapeutic modulators for Alzheimer's disease.

ABSTRACT: Reduced histone acetylation in the brain causes transcriptional dysregulation and cognitive impairment that are key initial steps in Alzheimer's disease (AD) etiology. Unfortunately, current treatment strategies primarily focus on histone deacetylase inhibition (HDACi) that causes detrimental side effects due to non-specific acetylation. Here, we test Tip60 histone acetyltransferase (HAT) activation as a therapeutic strategy for selectively restoring cognition-associated histone acetylation depleted in AD by developing compounds that enhance Tip60's neuroprotective HAT function. Several compounds show high Tip60-binding affinity predictions in silico, enhanced Tip60 HAT action in vitro, and restore Tip60 knockdown mediated functional deficits in Drosophila in vivo. Furthermore, compounds p
