Übersicht

Information

KU-0063794 is a potent and highly specific dual-mTOR inhibitor ofmTORC1andmTORC2withIC50of ~10 nM in cell-free assays; no effect on PI3Ks.
In vitro

Compared with the mTOR inhibitor PP242, KU-0063794 exhibits higher specificity for mTOR, as being inactive against PI3Ks or 76 other kinases. In HEK-293 cells, KU-0063794 at 30 nM is sufficient to rapidly ablate S6K1 activity by blocking the phosphorylation of the hydrophobic motif (Thr³⁸⁹) and subsequently the phosphorylation of the T-loop residue (Thr²²⁹). In case of IGF1 stimulation of serum-starved HEK-293 cells, 300 nM of KU-0063794 is needed to inhibit the S6K1 activity by ~90%. KU-0063794 at 100-300 nM also completely inhibits the amino-acid-induced phosphorylation of S6K1 and S6 protein. Similar to S6K1, KU-0063794 inhibits the phosphorylation of mTORC1 at Ser²⁴⁴⁸ and mTORC2 at Ser²⁴⁸¹ in a dose-dependent and time-dependent manner. In the presence of serum or following IGF1 stimulation, KU-0063794 induces a dose-dependent inhibition of the activity and phosphorylation of Akt at Ser⁴⁷³ and unexpected Thr³⁰⁸ as well as the phosphorylation of the Akt substrates PRAS40 at Thr²⁴⁶, GSK3α/GSK3β at Ser²¹/Ser⁹ and Foxo-1/3a at Thr²⁴/Thr³². KU-0063794 but not rapamycin inhibits SGK1 activity and Ser⁴²² phosphorylation as well as its physiological substrate NDGR1 in a dose-dependent manner, to the same extent as S6K1 and Akt phosphorylation, whereas KU-0063794 dose not inhibit phorbol ester induced ERK or RSK phosphorylation and RSK activation. Compared with rapamycin, KU-0063794 exhibits more significant potency to induce the complete dephosphorylation of 4E-BP1 at Thr³⁷, Thr⁴⁶ and Ser⁶⁵. KU-0063794 inhibits cell growth of both wild-type and mLST8-deficient MEFs and induces a G1 cell cycle arrest, more significantly than rapamycin.

In vivo

Ku0063794 inhibits tumor growth and mTOR signaling in a preclinical renal cell carcinoma model. However, Ku0063794 was not more effective than temsirolimus in the animal study. A possible explanation for lack of greater activity in vivo for Ku0063794 is that temsirolimus has important effects on the tumor microenvironment. Temsirolimus decreased angiogenesis in the xenograft tumors while Ku0063794 did not. Temsirolimus treated tumors expressed less VEGF and PDGF than Ku0063794 treated tumors, thus stimulating less angiogenesis.
