Torin 2 mTOR Inhibitor

Kat.-Nr.: S2817

Torin 2 ist ein potenter und selektiver mTOR-Inhibitor mit einem IC50-Wert von 0,25 nM in der p53−/− MEFs-Zelllinie; 800-fach höhere Selektivität für mTOR gegenüber PI3K und verbesserte pharmakokinetische Eigenschaften. Diese Verbindung hemmt ATM/ATR/DNA-PK mit EC50-Werten von 28 nM/35 nM/118 nM in PC3-Zelllinien. Sie verringert die Zellviabilität und induziert Autophagy sowie Apoptosis.

Torin 2 has the same binding mode as PI3Kγ, V882 serves as a hinge binding point and in the inner hydrophobic pocket Y867, D841 and D964 provide three more hydrogen bonds with aminopyridine side chain analogous to Y2225, D2195 and D2357 of mTOR. This compound inhibits mTORC1, thus activates TFEB by promoting its nuclear translocation with EC50 of 1.666 mM. This chemical (< 50 nM) causes a significant reduction in viability of both MZ-CRC-1 and TT cells. It (100 nM) exerts a significant reduction of migration of both MZ-CRC-1 and TT cells.

Kinase-Assay
mTOR- und PI3K-Zellassays
Zelluläre IC50-Werte für mTOR werden unter Verwendung von p53−/− MEFs bestimmt. Zellen werden 1 Stunde lang mit Vehikel oder steigenden Konzentrationen von Torin 2 behandelt und dann lysiert. Die Phosphorylierung von S6K1 Thr-389 wird mittels Immunoblotting unter Verwendung eines phospho-spezifischen Antikörpers überwacht. In der Zwischenzeit werden zelluläre IC50-Werte für PI3Ka basierend auf der Phosphorylierung von Akt Thr-308 in p53−/−/mLST8−/− MEFs oder menschlichen PC3-Zellen, die die S473D-Mutante von Akt1 exprimieren, bestimmt.
In vivo

Torin 2 exhibits >95% pharmacodynamic response and half-time of 11.7 min in the mouse liver microsome stability study. This compound exhibits the best bioavailability (51%), short half-life (0.72 hours) and low clearance(19.6 mL/min/kg) in male Swiss albino mice following intravenous and oral administration. This chemical (20mg/kg) ablates MYCN tumors with reduction in MYCN protein levels and induction of apoptosis in Th-MYCN mice.
