Application

KU 0063794 has been used:
  • as a mammalian target of rapamycin (mTOR) inhibitor to study the effects of follicular stimulating hormone (FSH) in mTOR phosphorylation and vascular cell adhesion molecule-1 (VCAM-1) expression in human umbilical vascular endothelial cells (HUVECs)
  • as a mTOR inhibitor to treat effector memory (EM) CD8+ T cells for metabolic flux analysis
  • as an autophagy inducer to demonstrate the utility of p62 and LC3B-II quantification in HEK293T cells and primary cultures of rat neurons and astrocytes using time-resolved fluorescence resonance energy transfer (TR-FRET)

Biochem/physiol Actions

KU 0063794 induces autophagy. It is cell-permeant and suppresses activation and hydrophobic motif phosphorylation of protein kinase B (Akt), p70 ribosomal S6 kinase (S6K) and serum and glucocorticoid protein kinase (SGK).
KU 0063794 is a potent and selective inhibitor of mammalian target of rapamycin (mTOR) (IC50 ~10 nM for both mTORC1 and mTORC2) that inhibits both mTORC1 and mTORC2 in vitro and in vivo (IC50 ~10 nM for both mTORC1 and mTORC2). KU 0063794 does not significantly inhibit 76 other protein kinases tested as well as seven lipid kinases including PI3K and AKT.
