Wirkmechanismus (Mechanism of Action)

Targets/IC₅₀/Ki	mTORC1 (Cell-free assay) ~10 nM mTORC2 (Cell-free assay) ~10 nM
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, this compound 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 this compound is needed to inhibit the S6K1 activity by ~90%. This chemical at 100-300 nM also completely inhibits the amino-acid-induced phosphorylation of S6K1 and S6 protein. Similar to S6K1, it 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, this compound 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. This compound 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 it dose not inhibit phorbol ester induced ERK or RSK phosphorylation and RSK activation. Compared with rapamycin, this chemical exhibits more significant potency to induce the complete dephosphorylation of 4E-BP1 at Thr³⁷, Thr⁴⁶ and Ser⁶⁵. It inhibits cell growth of both wild-type and mLST8-deficient MEFs and induces a G1 cell cycle arrest, more significantly than rapamycin.
Kinase-Assay	mTOR-Komplex-Kinase-Assays
Kinase-Assay	HEK-293-Zellen werden frisch in Hepes-Lysepuffer lysiert. Lysat (1-4 mg) wird durch Inkubation mit 5-20 μL Protein G-Sepharose, konjugiert an präimmunes IgG, vorklärt. Die Lysatextrakte werden dann mit 5-20 μL Protein G-Sepharose, konjugiert an 5-20 μg entweder Anti-Rictor- oder Anti-Raptor-Antikörper, oder präimmunes IgG, inkubiert. Alle Antikörper sind kovalent an Protein G-Sepharose konjugiert. Immunpräzipitationen werden 1 Stunde lang bei 4 °C auf einer Vibrationsplattform durchgeführt. Die Immunpräzipitate werden viermal mit Hepes-Lysepuffer gewaschen, gefolgt von zwei Waschschritten mit Hepes-Kinasepuffer. Für Raptor-Immunpräzipitate, die zur Phosphorylierung von S6K1 verwendet werden, enthält der Puffer für die ersten beiden Waschschritte 0,5 M NaCl, um eine optimale Kinaseaktivität zu gewährleisten. GST-Akt1 wird aus serumdeprivierten HEK-293-Zellen isoliert, die mit PI-103 (1 μM für 1 Stunde) inkubiert wurden. GST-S6K1 wird aus serumdeprivierten HEK-293-Zellen gereinigt, die mit Rapamycin (0,1 μM für 1 Stunde) inkubiert wurden. mTOR-Reaktionen werden durch Zugabe von 0,1 mM ATP und 10 mM MgCl₂ in Gegenwart verschiedener Konzentrationen von KU-0063794 und GST-Akt1 (0,5 μg) oder GST-S6K1 (0,5 μg) initiiert. Die Reaktionen werden 30 Minuten lang bei 30 °C auf einer Vibrationsplattform durchgeführt und durch Zugabe von SDS-Probenpuffer gestoppt. Reaktionsmischungen werden dann durch einen 0,22-μm-Porenfilter von Spin-X filtriert und Proben werden der Elektrophorese und Immunoblot-Analyse mit den angegebenen Antikörpern unterzogen.
In vivo	Ku0063794 inhibits tumor growth and mTOR signaling in a preclinical renal cell carcinoma model. However, this compound was not more effective in the animal study. A possible explanation for lack of greater activity in vivo for this chemical.
