Recombinant MAT2A was isolated from the cell lysate of 150 g of infected cells using HP Ni sepharose column chromatography. The recombinant MAT2A homodimer was eluted with 250 and 500 mM imidazole, and the MAT2A-containing fractions were 379 were identified by sodium dodecyl sulfate polyacrylamide gel electrophoresis and mixed. To determine the inhibitory potency of the compounds against the MAT2A homodimer, the protein was diluted to 4 μg / mL in assay buffer (50 mM Tris, pH 8.0, 50 mM KCl, 15 mM MgCl2, 0.3 mM EDTA, 0.005% [w / v] bovine serum albumin [BSA]). The assay compound was prepared in 100% dimethyl sulfoxide (DMSO) at 50x the desired final concentration. A 1 μL volume of the compound dilution was added to 40 μL of enzyme dilution, and the mixture was allowed to equilibrate for 60 minutes at 25°C. The enzyme assay was started by adding 10 μR of the substrate mixture (500 μM ATP, pH 7, 0.400 μM P-methionine in 1x assay buffer) and the mixture was incubated for a further 60 minutes at 25°C. The reaction was stopped and the phosphate released by the enzyme was measured in stoichiometric amounts by the production of Sadenosyl methionine (SAM) using the PiColorLock Gold kit (Innova Biosciences, UK).The absolute quantities of the product were determined by comparison with a normal curve of potassium phosphate buffer, pH 8.0. The specific compounds disclosed herein were tested in the preceding assay and were determined to inhibit MAT2A with an IC50 according to the following ratings: 380 (A) less than 100 nM, (B) between 100 nM and 1 μM and (C) between 1 μM and 10 μM, as shown in Table 4 below. Example 276 White Gear Cell Assay (SAM) MAT2A activity in cells was measured by directly quantifying the abundance of its enzyme product, SAM. Cancer cells were treated with candidate MAT2A inhibitors for an appropriate incubation period, and the cells were then lysed using a reagent that quenched any other enzymatic activity. Soluble metabolites, including SAM, were collected, and SAM itself was measured directly from the lysate using quantitative LC-MS / MS. A typical assay was performed using a human colon carcinoma HCT116 cell line that was genetically engineered to delete the MTAP gene (commercially available in Horizon Discovery). This cell line was used because loss of the MTAP gene has been shown to predict sensitivity to MAT2A inhibitors. Cells were seeded in 96-well plates at the appropriate cell density. After 24 hours, the cells were then treated with the candidate MAT2A inhibitor. Prior to cell addition, the compound was serially diluted first in 100% DMSO, typically as a 3-fold serial dilution starting at the higher dose. 381 of 500x with 10 dose points including DMSO as the sole control. The compound was then transferred to a working raw material plant in cell culture medium by adding 5 pl of the compound in DMSO to 495 pl of cell culture medium. This working raw material was then added to cells by another 5-fold dilution, adding 25 pl of working raw material to 100 pl of cells in culture medium. After compound addition, the cells were incubated at 37 °C / 5% CO2 for 72 hours. To measure SAM levels after treatment with the compound, cells were gently washed once in ammonium carbonate buffer (75 mM at pH 7.4), placed on dry ice, and lysed with a metabolite extraction buffer (80% cold methanol and 20% water (v / v) with acetic acid to a final concentration of 1 M with 200 ng / mL of deuterated d3-SAM as an internal control). After centrifugation at 4 °C at 3,200 rpm for 30 minutes, the supernatant was collected and stored at -80 °C until analysis by Liquid Chromatography-Tandem Mass Spectrometry (LC-MS / MS). The LC-MS / MS analysis was performed using an API6500 Mass Spectrometer (Sciex, Framingham, MA, USA) operating in positive ion sputtering mode and equipped with a BEH Amida Waters UPLC Acquity column (Waters, Milford, MA, USA). 382 acquired Multiple Reaction Monitoring data for SAM and the d3-SAM norm, using a mass transition pair am / z 399.2^250.1 and 402.2^250.1, respectively. In a normal LC-MS / MS analysis, the initial flow rate was 0.5 ml / min of 25% mobile phase A (acetonitrile and water at 5:95 (v / v) with 1% formic acid and 10 mM ammonium acetate) and 75% mobile phase B (acetonitrile and water at 95:5 (v / v) with 1% formic acid and 10 mM ammonium acetate), 0.2-0.5 min with 75%-35% mobile phase B, 25%-65% mobile phase A, to 0.5 min with 65% mobile phase A and 35% mobile phase B, 1.0-1.1 min with 35%-75% mobile phase B, 65%-25% mobile phase A, to 1.1 min with 25% mobile phase A and 75% of mobile phase B with a total circulation time of 1.5 minutes. The specific compounds disclosed herein were tested in the preceding assay and were determined to inhibit SAM with an IC50 according to the following ratings: (A) less than 100 nM (> 60% maximum inhibition), (B) between 100 nM and 1 pM (> 60% maximum inhibition) and (NT) not tested, as shown in Table 4 below. Example 277: Assay for Inhibition of Proliferation Cellular 383 The impact of the compound on cancer cell growth was evaluated by treating cancer cells with the compound for 4 days and then measuring proliferation using an ATP-based cell proliferation readout (Cell Titer Glo, Promega Corporation). In a standard assay, an isogenic pair of human HACT116 colon carcinoma cell lines that differ only in their MTAP deletion status (HCT116 MTAP+ / + and HCT116 MTAP- / -) were placed in 96-well plates at the appropriate cell density. After 24 hours, the cells were treated with the candidate MAT2A inhibitor. Before cell addition, the compound was serially diluted in 100% DMSO (typically as a 3x dilution starting at a 500x upper dose with 10 dose points including DMSO as the sole control). The compound was then transferred to a working stock plate in cell culture medium by adding 5 µl of the compound in DMSO to 495 µl of cell culture medium. The working stock was then added to the cells by another 5x dilution, adding 25 µl of the working stock to 100 µl of cells in the culture medium.After the compound was added, the cells were incubated at 37 °C / 5% CO2 for 4 days. 384 To measure cell proliferation inhibition, cells were allowed to equilibrate to room temperature for 30 minutes and then treated with 125 pL of Cell Titer Glo reagent. The plate was then covered with an aluminate foil and shaken for 15 minutes to ensure thorough mixing and complete cell lysis. The luminescent signal was then measured using a Veritas plate-based luminometer, version 1.9.2, using the ATP normal curve to confirm assay reproducibility from run to run. This luminescence measurement was converted into a proliferation index by subtracting the ATP luminescence signal measured from a blank (no cells) dish from each data point and dividing by the ATP luminescence signal measured in a 0.2% DMSO control dish adjusted for the blank dish signal.The compound's activity was then represented as a percentage change in proliferation relative to control DMSO within the plaque versus log10 of the compound's concentration in molar units (M). The specific compounds disclosed herein were tested in the following assay and were determined to inhibit cell proliferation with an IC50 according to the following ratings: (A) less than 100 nM (>30% maximum inhibition for MTAP - / -; >10% maximum inhibition for MTAP + / +), (B) 385 between 100 nM and 10 μM (> 30% maximum inhibition for MTAP - / -; > 10% maximum inhibition for MTAP + / + ), (C) more than 10 μM and (NT) not tested, as shown in Table 4 below.
