| Name | PF-9366 |
| Description | PF-9366 is a human methionine adenosyltransferase 2A (Mat2A) inhibitor with an IC50 of 420 nM and a Kd of 170 nM. |
| Cell Research | Huh-7 cells are seeded at a concentration of 15,000 cells per well for 6-h incubation with compound (PF-9366) and 4,000 cells per well for 72-h incubation with the compound in 96-well plates in 200 μL of growth medium. NCI-H520 MAT2B knockdown cells are seeded at a concentration of 20,000 cells per well for 6 h incubation or 10,000 cells per well for 72 h incubation with the compound in 96 well plates in 200 μL of growth medium. Cells are allowed to attach overnight at 37°C with 5% CO2. A 5× solution of cycloleucine is prepared fresh from powder stock in the growth medium. Other compounds (PF-9366) are diluted in 100% DMSO using a three-fold dilution scheme and further diluted in growth medium to give 0.5% DMSO final. Consistency of cellular confluence for each cell line is monitored with the IncuCyte Zoom live cell imager. Proliferation is measured using CellTiterGlo reagent. Growth media is removed from the cell plates following compound treatment and 80 μL/well CellTiter Glo diluted 1:1 in PBS added. |
| Kinase Assay | The Mat2A and Mat2B proteins are extensively dialyzed into a buffer containing 150 mM KCl, 25 mM HEPES, pH 7.4, 5 mM MgCl2, 5% (v/v) glycerol, 2 mM TCEP. Concentrations are determined spectrophotometrically using an ?280 of 44,350 /M.cm for Mat2A and an ?280 of 36,440 /M.cm for Mat2B. PF-9366 are diluted from 100% DMSO stocks into a buffer without DMSO. In a typical experiment, nineteen 15 μL injections of 200 μM compound or 30-35 μM Mat2B are made into 10 μM Mat2A on a VP ITC or nineteen 2 μL injections of 200 μM compound into 10 μM Mat2A on an Auto iTC200. |
| In vitro | H520 lung carcinoma cells were treated with PF-9366 for 6 h. PF-9366 inhibited cellular SAM production with an IC50 of 1.2 μM. The IC50s of PF-9366 was modestly decreased in the H520 cells with Mat2B knockdown, to 0.86 mM. Huh-7 cells were more sensitive to compound exposure than the H520 cell line. After 6-h exposure to PF-9366, the IC50 for SAM synthesis inhibition was 225 nM. |
