In vitro
AT7867 also inhibits structurally related AGC kinases p70S6K and PKA with IC50 of 20 nM and 85 nM, respectively. This compound shows ATP-competitive activity to Akt2 with Ki of 18 nM. It exhibits antiproliferation in cell lines with PTEN or PIK3CA mutations and shows great potent to MES-SA, MDA-MB-468, MCF-7, HCT116 and HT29 with IC50 of 0.94 μM, 2.26 μM, 1.86 μM, 1.76 μM and 3.04 μM, respectively. This chemical also suppresses the cell growth of U87MG, PC-3 and DU145 cells with IC50 of 8.22 μM, 10.37 μM and 11.86 μM, respectively. It suppresses Akt activity by inhibiting phosphorylation of GSK-3β in human tumor cells with IC50 of 2-4 μM. This compound also induces the phosphorylation of the following Akt direct substrates including proapoptotic transcription factors FKHR (FoxO1a), FKHRL1 (FoxO3a) and the downstream target S6RP in U87MG cells.
Kinase Assay
In vitro kinase assays
Kinase assays for Akt2, PKA, p70S6K, and CDK2/cyclin A are all carried out in a radiometric filter binding format. Assay reactions are set up in the presence of AT7867. For Akt2, the Akt2 enzyme and 25 μM Aktide-2T peptide (HARKRERTYSFGHHA) are incubated in 20 mM MOPS (pH 7.2), 25 mM β-glycerophosphate, 5 mM EDTA, 15 mM MgCl2, 1 mM sodium orthovanadate, 1 mM DTT, 10 μg/mL bovine serum albumin, and 30 μM ATP (1.16 Ci/mmol) for 4 hours. For PKA, the PKA enzyme and 50 μMpeptide (GRTGRRNSI) are incubated in 2 mM MOPS (pH 7.2), 25 mM β-glycerophosphate, 5 mM EDTA, 15 mM MgCl2, 1 mM orthovanadate, 1 mM DTT, and 40 μM ATP (0.88 Ci/mmol) for 20 minutes. For p70S6K, the p70S6K enzyme and 25 μMpeptide substrate (AKRRRLSSLRA) are incubated in 10 mM MOPS (pH 7), 0.2 mM EDTA, 1 mM MgCl2, 0.01% β-mercaptoethanol, 0.1 mg/mL bovine serum albumin, 0.001% Brij-35, 0.5% glycerol, and 15 μM ATP (2.3 Ci/mmol) for 60 min. For CDK2, the CDK2/cyclin A enzyme and 0.12 μg/mL histone H1 are incubated in 20 mM MOPS (pH 7.2), 25 mM β-glycerophosphate, 5 mM EDTA, 15 mM MgCl2, 1 mM sodium orthovanadate, 1 mM DTT, 0.1 mg/mL bovine serum albumin, and 45 μM ATP (0.78 Ci/mmol) for 4 hours. Assay reactions are stopped by adding an excess of orthophosphoric acid, and the stopped reaction mixture is then transferred to Millipore MAPH filter plates and filtered. The plates are then washed, scintillant is added, and radioactivity is measured by scintillation counting on a Packard TopCount. IC50 values are calculated from replicate curves using GraphPad Prism software. Akt1 and Akt3 enzyme assays are carried out.
In vivo
AT7867 shows bioavailability of 44% in mice by p.o. route. This compound could increase the cleaved PARP in MES-SA xenografts at 20 mg/kg i.p. or 90 mg/kg p.o.. It significantly inhibits the tumor growth in MES-SA xenografts or U87MG xenografts with T/C of 0.37 and 0.51, respectively.
