Target: Fatty acid synthase (SINGLE PROTEIN), Homo sapiens
UniProt: P49327
Assay: Biochemical Assay: The FASN enzyme was isolated from SKBr3 cells. SKBr3 is a human breast cancer cell-line with high levels of FASN expression. It is estimated that FASN comprises about 25% of the cytosolic proteins in this cell line. SKBr3 cells were homogenized in a dounce homogenizer then centrifuged for 15 minutes at 4° C. to remove particulate matter. The supernatant was then analyzed for protein content, diluted to the appropriate concentration, and used to measure FASN activity. The presence of FASN was confirmed by western blot analysis. A similar method for isolation of FASN from SKBr3 cells is described in Teresa, P. et al. (Clin. Cancer Res. 2009; 15(24), 7608-7615). FASN activity of the SKBr3 cell extract was determined by measuring either NADPH oxidation or the amount of thiol-containing coenzyme A (CoA) released during the fatty acid synthase reaction. The dye CPM (7-diethylamino-3-(4'-maleimidyl-phenyl)-4-methylcoumarin) contains a thiol reactive group that increases its fluorescence emission on reaction with the sulfhydryl group of CoA.

The inhibitor concentration is varied between 0.02-30,000 nM, while the Hsp27 peptide substrate and MgATP are held constant at 1 μM and 10 μM, respectively. Activated p38α is added to a final concentration of 20 pM for reactions with nonphosphorylated 1 nM His6-MK2 in the cascade reaction. For the p38α/PRAK cascade, unactivated GST-PRAK is held constant at 1 nM while p38α is added in to a final concentration of 20 pM. Kinase reactions are incubated at room temperature and quenched after 30 minutes by the addition of stop buffer (180 mM HEPES, 30 mM EDTA, and 0.2% Coating Reagent-3). Under these conditions, approximately 20% of the substrate Hsp27 peptide is phosphorylated. Reactions are initiated by the addition of activated p38α except for preincubation experiments, where reactions are initiated by the addition of Hsp27 peptide and MgATP. Preincubation of p38α with inhibitor or p38α with unactivated His6-MK2 or unactivated GST-PRAK and inhibitor are performed at 2X final assay concentrations at room temperature 240 minutes prior to adding ATP and Hsp27 peptide to initiate catalysis.

Assay: Enzymatic Screening Assay: The enzymatic test is a test in two steps.In a first step, it consists in placing in contact the compound according to the invention, the dialysed MetAP2 protein and the substrate (Met-Pro-Arg-pNa peptide synthesized by Neosystem), the N-terminal methionine of which can be cleaved with MetAP2, and which bears at the C-terminal end a para-nitroaniline (pNa) chromophore, which can itself be released by another peptidase only when the N-terminal methionine has been cleaved beforehand.Consequently, the second step consists in reacting the peptides cleaved in the preceding step with a second peptidase in order to release the chromophore. The peptidase used in this second step is cathepsin, which comes from the TagZyme DAPase kit (Quiagen, 34366).The MetAP2 activity is proportional to the amount of para-nitroaniline released, which is measured by absorbance at 405 nm.

Assay: Time Resolved-Fluorescence Resonance Energy Transfer (TR-FRET) Assay: Representative compounds were serially diluted in dimethyl sulfoxide (DMSO) starting at 50 uM (2x starting concentration; 10% DMSO) and 10 uL were transferred into a 384-well plate. Then 10 uL of a protein/probe/antibody mix was added to each well at final concentrations listed in TABLE 1. The samples are then mixed on a shaker for 1 minute and incubated for an additional 3 hours at room temperature. For each assay, the probe/antibody and protein/probe/antibody were included on each assay plate as negative and positive controls, respectively. Fluorescence was measured on the ENVISION plate reader (Perkin Elmer) using a 340/35 nm excitation filter and 520/525 (F-Bak peptide) and 495/510 nm (Tb-labeled anti-Histidine antibody) emission filters Inhibition constants (Ki) are shown in TABLE 2 below and were determined using Wang's equation (Wang Z.-X. An Exact Mathematical Expression For Describing Competitive Binding Of Two Different Ligands To A Protein Molecule. FEBS Lett. 1995, 360:111-4).

Assay: Time-Resolved Fluorescence Resonance Energy Transfer (TR-FRET) Binding Assay : Probe 2:The assay was carried out in 18 uL low volume plates (Owens Corning) in reaction buffer (50 mM HEPES (NaOH), pH 7.5, 100 mM NaCl, 10 mM MgCl2, 1 mM DTT, 1% Glycerol) using 6.8 nM recombinant, human, C-terminally-His tagged NAMPT, 1 nM Tb-anti-His antibody (Invitrogen, Cat #PV5895), and 200 nM probe (Oregon Green 488-conjugated APO0866; A-1287128.0. Plates were covered, and reactions were carried out for 2-3 hours. Plates were read with Envision (Laser Lantha low volume protocol) after 2 to 3 hours. Excitation was carried out at 337 nm, and the ratio of emission of Oregon Green (520 nm) to terbium (492 nm) was determined and used to calculate IC50 values of test compounds.
Measurement: IC50 = 436 nM (pChEMBL 6.360000133514404)
