XL388 (Compound 28) also inhibits DNA-PK with an IC50 of 8.831 μM. XL388 inhibits cellular phosphorylation of mTOR complex 1 (p-p70S6K, pS6, and p-4E-BP1) and mTOR complex 2 (pAKT (S473)) substrates. XL388 acts in an ATP-competitive manner, with a linear increase in IC50 values with increasing ATP concentration[1]. XL388 shows a dose-dependent effect in promoting MG-63 cell apoptosis. XL388 (100 nM) induces apoptosis in other two OS cell lines (U2OS and SaOs-2), but not in non-cancerous MC3T3-E1 cells. XL388 potently inhibits activation of both mTORC1 and mTORC2 in MG-63 cells. The effect of XL388 on mTORC1/2 activation is again dose-dependent. Further, mTORC1/2 activation is almost blocked in XL388 (100 nM)-treated U2OS cells, SaOs-2 cells and primary human OS cells[2].

The measurement of mTOR enzyme activity is performed in an ELISA format following the phosphorylation of 4E-BP1 protein. All experiments are performed in the 384-well format. Generally, 0.5 μL of DMSO containing varying concentrations of the test compound is mixed with 15 μL of the enzyme solution. Kinase reactions are initiated with the addition of 15 μL of a solution containing the substrate. The assay conditions are as follows: 0.2 nM mTOR, 10 μM ATP, and 50 nM NHis-tagged 4E-BP1 in 20 mM Hepes, pH 7.2, 1 mM DTT, 50 mM NaCl, 10 mM MnCl2, 0.02 mg/mL BSA, 0.01% CHAPS, 50 mM β-glycerophophate. Following an incubation of 120 min at ambient temperature, 20 μL of the reaction mixture is transferred to a Ni-chelate-coated 384-well plate. The binding step of the 4E-BP1 protein proceeded for 60 min, followed by washing four times each with 50 μL of Tris-buffered saline solution (TBS). Anti-phospho-4E-BP1 rabbit immunoglobulin G (IgG; 20 μL, 1:5000) in 5% BSA-TBST (0.2% Tween-20 in TBS) is added, and the reaction mixuture is further incubated for 60 min. Incubation with a secondary horseradish peroxidase (HRP)-tagged anti-IgG is similarly performed after the primary antibody is washed off (four washes of 50 μL). Following the final wash step with TBST, 20 μL of SuperSignal ELISA Femto is added and the luminescence measured using an EnVision plate reader. Data are reported as the mean (n≥2) [1].

U2OS, SaOs-2 and MG-63 OS cell lines as well as the murine calvaria-derived osteoblastic MC3T3-E1 cells are maintained and culture. The OB-6 human osteoblastic cells are cultured. For primary culture of murine osteoblasts, the trimmed calvariae of neonatal mice are digested with 0.1% collagenase I and 0.25% dispase. The resolving cell suspensions are neutralized with complete culture medium and are filtered. The calvarial osteoblasts are then resuspended in 10 mL α-MEM containing 15% FBS, and are cultured. Cells (5×104/well) are suspended in 1 mL of DMEM with 1% agar, 10 % FBS and with indicated XL388 (5, 25, 100 and 200nM) treatment. The cell suspension is then added on top of a pre-solidified 1% agar in a 100 mm culture dish. The drug containing medium is refreshed every 2 days. After 10-day incubation, the number of remaining colonies are stained and manually counted[2].

Mice, Rats, Dogs and Monkeys[1]
Pharmacokinetic studies of XL388 are determined in female athymic nude mice, female CD rats, male beagle dogs, and male cynomolgus monkeys. XL388 is administered intravenously and by oral gavage at 10 mg/kg as a solution formulated in EPW (5% ethanol/45% PEG400/water+1:2 HCl (m/m)) to mice, 3 mg/kg as a solution formulated in EPW (5% ethanol/45% PEG400/water+1:2 HCl (m/m)) to CD rats and male beagle dogs, and 3 mg/kg as a solution formulated in EPW (5% ethanol/45% PEG400/water+1:1.5 HCl (m/m)) to male cynomolgus monkeys. The plasma levels of XL388 are monitored over a 24 h period.
