实验参考方法

Kinase experiment:

Kinase assays for AKT2, PKA, p70S6K and CDK2/cyclinA are all carried out in a radiometric filter binding format. Assay reactions are set up in the presence of compound. 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 BSA and 30 μM ATP (1.16 Ci/mmol) for 4 hours. For PKA, the PKA enzyme and 50 μM peptide (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 μM peptide 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 BSA, 0.001% Brij-35, 0.5% glycerol and 15μM ATP (2.3 Ci/mmol) for 60 minutes. For CDK2, the CDK2/cyclinA 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 BSA 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 added and radioactivity measured by scintillation counting on a Packard TopCount. IC50 values are calculated from replicate curves using GraphPad Prism software. AKT1 and 3 enzyme assays are carried out, while all other enzyme assays are performed[1].

Cell experiment:

Cells are plated in 96-well microplates at 16,000 cells per well in medium supplemented with 10% FBS, and grown for 24 hours before treatment with AT7867. AT7867 or vehicle control are added to the cells for 1 hour. Following this, cells are fixed with 3% paraformaldehyde, 0.25% glutaraldehyde, 0.25% Triton-X100, washed and blocked with 5% milk in tris-buffered saline with 0.1% Tween-20 (TBST) prior to overnight incubation with a phospho-GSK3β (serine 9) antibody. The plates are then washed, secondary antibody added, and enhancement of the signal performed using DELFIA reagents. Europium counts are normalized to the protein concentration, and the IC50 value for each inhibitor is calculated in GraphPad Prism using non-linear regression analysis and a sigmoidal dose-response (variable slope) equation[1].

Animal experiment:

Mice[1] Male athymic BALB/c mice (nu/nu) are used. A single dose of AT7867 is administered to BALB/c mice at 5 mg/kg intravenously (i.v.) and 20 mg/kg per os (p.o.). Plasma samples are collected from duplicate animals at each of the following time points; 0.083, 0.167, 0.33, 0.67, 1, 2, 4, 6, 16 and 24 hours following i.v. dosing and at 0.25, 0.5, 1, 2, 4, 6 and 24 hours following p.o. dosing. Mice are bled by cardiac puncture and all blood samples are centrifuged to obtain plasma, which is then frozen at -20°C until analysis. For bioanalysis, all plasma samples are prepared by protein precipitation with acetonitrile containing internal standard. Quantification of sample extracts is by comparison with a standard calibration line constructed with AT7867 and using an inhibitor specific liquid chromatography tandem mass spectrometry (LC-MS/MS) method. Pharmacokinetic parameters are determined.

产品描述

IC50: AKT1 32 nM, AKT2 17 nM, AKT3 47 nM, PKA 20 nM
The serine/threonine kinase AKT plays a pivotal role in signal transduction events involved in malignant transformation and chemoresistance and is an attractive target for the development of cancer therapeutics. Structure-based drug design and fragment-based lead discovery have identified AT7867 as a novel and potent inhibitor of both AKT and the downstream kinase p70 S6 kinase (p70S6K) and also of protein kinase A.
In vitro: AT7867 potently inhibits both AKT and p70S6K activity, measured by inhibition of protein phosphorylation of GSK3β and S6 ribosomal, and also the growth inhibition in a panel of human cancer cell lines. Induction of apoptosis by AT7867 was detected by multiple methods in tumor cells followingAT7867 treatment [1].
In vivo: Administration ofAT7867 (90 mg/kg p.o. or 20 mg/kg i.p.) to athymic mice implanted with the PTEN-deficient U87MG human glioblastoma xenograft model caused inhibition of phosphorylation of downstream substrates of both AKTand p70S6K and induction of apoptosis. These AT7867 doses also led to inhibition of human tumor growth in PTEN-deficient xenograft models. These findings suggest that a novel strategy of AKT and p70S6K blockade may have therapeutic value and supports further evaluation of AT7867 as a singleagent anticancer strategy [1].
Clinical trial: Currently no clinical data are available.
