 Use of SEW84


SEW84 (SEW04784) is a first-in-class, specific inhibitor of the Aha1-stimulated Hsp90 (ASH) ATPase activity (IC50=0.3 uM) without inhibiting basal Hsp90 ATPase;SEW84 binds to the C-terminal domain of Aha1 (Kd=1.7 uM) to weaken its asymmetric binding to Hsp90.SEW84 inhibited the GR- and AR-dependent luciferase expression with IC50 of 1.3 uM and 0.7 uM respectively.SEW84 blocks Aha1-dependent Hsp90 chaperoning activities, including the in vitro and in vivo refolding of firefly luciferase, and the transcriptional activity of the androgen receptor in cell-based models of prostate cancer.SEW84 promotes the clearance of phosphorylated tau in cellular and tissue models of neurodegenerative tauopathy.
