PP242 exhibits potent selectivity for mTOR over other PI3K family kinases such as p110α, p110β, p110γ, p110δ, and DNA-PK with IC50 of 1.96 μM, 2.2 μM, 1.27 μM, 0.102 μM, and 0.408 μM, respectively. This compound displays some inhibitory activity against Ret, PKCα, PKCβ, and JAK2, while exhibits remarkable selectivity against 215 other protein kinases. Unlike rapamycin, this inhibitor inhibits both mTORC1 and mTORC2. In BT549 cells, this chemical treatment (0.04-10 μM) inhibits the phosphorylation of Akt, the mTOR substrate p70S6K, and its downstream target S6 in a dose-dependent manner. It potently inhibits PKCα with IC50 of 49 nM. Low concentrations of this compound inhibit the phosphorylation of Akt S473 and higher concentrations partially inhibit Akt T308-P in addition to S473-P. As this agent is a more effective mTORC1 inhibitor than rapamycin, it inhibits the proliferation of primary MEFs, and the phosphorylation of 4EBP1 at T36/45 and S65, more potently than rapamycin. This compound but not rapamycin potently inhibits cap-dependent translation, by causing a higher level of binding between 4EBP1 and eIF4E than rapamycin. It potently inhibits the proliferation of p190-transformed murine BM, SUP-B15, and K562 cells with GI50 of 12 nM, 90 nM, and 85 nM, respectively. This inhibitor also inhibits the growth of solid tumor cell lines such as SKOV3, PC3, 786-O, and U87 with GI50 of 0.49 μM, 0.19 μM, 2.13 μM, and 1.57 μM, respectively. It is also more effective than rapamycin in achieving cytoreduction and apoptosis in multiple myeloma (MM) cells.
Kinase Assay
In vitro mTOR (FRAP1) kinase assay
Recombinant mTOR wordt geïncubeerd met deze verbinding in 2-voudige verdunningen over een concentratiebereik van 50-0,001 μM in een assay die 50 mM HEPES, pH 7,5, 1 mM EGTA, 10 mM MgCl2, 0,01% Tween, 10 μM ATP (2,5 μCi γ-32P-ATP) en 3 μg/mL BSA bevat. Rat recombinant PHAS-1/4EBP1 (2 mg/mL) wordt gebruikt als substraat. Reacties worden beëindigd door op nitrocellulose te spotten, die wordt gewassen met 1 M NaCl/1% fosforzuur (ongeveer 6 keer, elk 5-10 minuten). De vellen worden gedroogd en de overgedragen radioactiviteit gekwantificeerd door fosforbeeldvorming. De IC50-waarde wordt berekend door de gegevens te fitten aan een sigmoïdale dosis-respons curve met behulp van het Prism-softwarepakket.
In vivo
Administration of PP242 is able to completely inhibit the phosphorylation of Akt at S473 and T308 in fat and liver of mice. This compound only partially inhibits the phosphorylation of Akt in skeletal muscle and is more effective at inhibiting the phosphorylation of T308 than S473, despite able to fully inhibit the phosphorylation of 4EBP1 and S6. Oral administration of this chemical potently delays the leukemia onset in the mice model, and induces leukemia regression by inhibiting mTORC2 and mTORC1 activation that correlates with loss in cell size. This treatment potently inhibits the growth of 8226 cells in mice.

Vraag 1:
Do you have any suggestions about potential candidates for vehicles that we could use for in vivo studies of it?

Antwoord:
In the recommended solvent (30% PEG400 + 0.5% Tween80 + 5% Propylene glycol), it is a suspension, and this formulation is for oral gavage. For IV injection, this compound can be dissolved in 2% DMSO+30% PEG 300+5% Tween 80+ddH2O at 5mg/ml as a clear solution.
