The mammalian target of rapamycin (mTOR) is a serine-threonine kinase which acts as part of two distinct complexes, TORC1 and TORC2. Both complexes (TORC1/2) play central roles in cell growth, gene expression, angiogenesis, and cell survival. Ku-0063794 is a cell-permeable, selective dual inhibitor of mTORC1 and mTORC2 (IC50 = 10 nM). It does not affect the activity of 76 other protein kinases or seven lipid kinases, including PI3Ks. Ku-0063794 inhibits cell growth by inducing G1-cell cycle arrest and autophagy, but not apoptosis, and inhibits tumor growth in a xenograft model of renal cell carcinoma (8 mg/kg for 46 days).
용도
Ku 0063794 is a specific mammalian target of rapamycin (mTOR) inhibitor and may be used for the treatment of cancers.
정의
ChEBI: A member of the class of pyridopyrimidines that is an mTOR inhibitor and shows anti-tumour properties.
생물학적 활성
Selective inhibitor of mammalian target of rapamycin (mTOR) (IC 50 ~10 nM for mTORC1 and mTORC2 respectively). Displays no activity at PI 3-kinase or 76 other kinases tested. Inhibits activation and hydrophobic motif phosphorylation of Akt, S6K and SGK, but not RSK. Suppresses cell growth and induces G 1 cell cycle arrest in vitro .
