SEW84 is a potent and selective inhibitor of the Aha1-stimulated Hsp90 ATPase activity without inhibition of basal Hsp90 ATPase. It binds to the C-terminal domain of Aha1 and weakens the Hsp90-Aha1 interaction. SEW84 inhibits Aha1-dependent Hsp90 chaperoning activities including refolding of denatured firefly luciferase (in vitro) and in vivo transcriptional activity of the glucocorticoid receptor and AR androgen receptor in prostate cancer cell-based models. SEW84 preferentially clears Alzheimer disease related phosphorylated aggregation-prone Tau in primary rat cortical neurons.

Hsp90 plays an important role in health and is a therapeutic target for managing misfolding disease. Compounds that disrupt co-chaperone delivery of clients to Hsp90 target a subset of Hsp90 activities, thereby minimizing the toxicity of pan-Hsp90 inhibitors. Here, we
