Target: Methionine aminopeptidase 2 (SINGLE PROTEIN), Homo sapiens
UniProt: P50579
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.

The phosphorylation of biotinylated-BAD (S112) peptide by full length recombinant Pim-1, Pim-2, or Pim-3 protein was detected with streptavidin:Allophycocyanin (APC) conjugate and a europium (Eu) labeled antibody directed against phosphorylated-BAD (S112). Excitation of Eu by a high energy laser light (337 nm) leads to a transfer of energy to the APC molecule, and results in an emission at 665 nm. The fluorescence is directly proportional to the amount of phosphorylated BAD peptide present in the reaction. Compounds were prepared in DMSO by conducting 3-fold serial dilutions to give a 22-point dosing curve having a high dose of 1 μM. A reference compound was included on each assay plate [Costar 3658] in order to validate that plate; on one plate of every assay run, two additional reference compounds were included. The Reaction Buffer consisted of 45 mM Hepes, pH 7.0, 15 mM NaCl, and 1 mM MgCl. The quench/detection buffer consisted of 50 mM Tris, 100 mM NaCl, 0.05% BSA, 0.1% Tween and 3 mM EDTA. Biotinylated BAD peptide (Biopeptide), 10 mM ATP (Sigma), Labeled p-BAD (S112) mAb (Cell Signalling and Perkin Elmer) [with 0.05% BSA and 2 mM DTT added] streptavidin:Allophycocyanin [Perkin Elmer]. Final concentrations either Pim-1 enzyme [5 pM], or Pim-2 enzyme [0.5 pM], DMSO [1%], BLC BAD (S112) [0.5 μM], ATP [1.5 μM], streptavidin:Allophycocyanin [0.002 mg/mL] and biotinylated-BAD (S112) mAb [100 pM]. Initial incubations were carried out at RT (22° C.) for 30 min for both Pim-1 and for Pim-2. Pim enzyme is added to compound in buffer, and plates are incubated of 30 min. Biotinylated BAD and ATP are added and plates are incubated for 1 h. A mixture of labeled p-BAD (S112) mAb and quench/detection buffer are added and incubated for 2 h. Fluorescence was measured by an HTRF® Envision microplate reader.

Assay: Surface plasmon resonance (SPR): Methods for Determining IC50s.The present method includes utility of a Surface plasmon resonance (SPR)- based biosensor (Biacore GE Healthcare, Uppsala, Sweden) to characterize BCL-2 inhibitors.Biacore utilizes the phenomenon of surface plasmon resonance (SPR) to detect and measure binding interactions. In a typical Biacore experiment, one of the interacting molecules (ligand) is immobilized on a flexible dextran matrix while the interacting partner (analyte) is allowed to flow across that surface. A binding interaction results in an increase in mass on the sensor surface and a corresponding direct change in the refractive index of the medium in the vicinity of the sensor surface. Changes in refractive index or signal are recorded in resonance units (R.U.) Signal changes due to association and dissociation of complexes are monitored in a non-invasive manner, continuously and in real-time, the results of which are reported in the form of a sensorgram.

Assay: Glucokinase-Activating Assay: To test the exemplified compounds, the following assay was employed. Recombinant human liver glucokinase was expressed as a FLAG fusion protein in E. coli, and purified on ANTIFLAG M2 AFFINITY GEL (Sigma). The assay was carried out at 30° C. in a 96-well plate. In the plate was distributed 69 ul each of assay buffer (25 mM Hepes Buffer: pH=7.2, 2 mM MgCl2, 1 mM ATP, 0.5 mM TNAD, 1 mM dithiothreitol), to which was added 1 ul of a DMSO solution of the compound or DMSO as control. Then, 20 ul of pre-ice-cooled enzyme mixture (FLAG-GK, 20 U/ml G6PDH) was distributed thereto, to which was added 10 ul of 25 mM glucose as substrate to initiate the reaction (final glucose concentration=2.5 mM). After starting the reaction, the absorbance at 405 nm was measured every 30 seconds for 10 minutes to evaluate the compound based on the initial increase for 5 minutes. FLAG-GK was added so that the increase of absorbance after 5 minutes fell between 0.05 to 0.1 in the presence of 1% DMSO. The OD values of the respective compounds were measured in the respective concentrations, wherein the OD value of DMSO as control is regarded as 100%. From the OD values at the respective concentrations, Emax (%, 2.5 mM Glu) and EC50 (nM, 2.5 mM Glu) were calculated and used as indicators of the GK activation capability of the compounds. According to the above assay, the GK activation capability of the exemplified compounds of the present invention was determined. The following table shows the results. Where different enantiomers of the same compound were tested, two numbers are provided. Where 3 numbers are provided, for example, Ex. #30, data for the racemic form is also shown.

Assay: B-RAF (V600E) Kinase Assay: In a dilution series 10 uL/well of test substance solution are placed in a multiwell plate. The dilution series is selected so that generally a range of concentrations of 2 uM to 0.119 nM or 0.017 nM is covered. If necessary the initial concentration of 2 uM is changed to 50 uM, 10 uM or 0.4 uM or 0.2857 uM and further dilution is carried out accordingly. The final concentration of DMSO is 5%. 10 uL/well of the B-Raf (V600E)-kinase solution are pipetted in (containing 0.5 ng B-Raf (V600E)-kinase (e.g. from Upstate) in 20 mM Tris-HCl pH 7.5, 0.1 mM EDTA, 0.1 mM EGTA, 0.286 mM sodium orthovanadate, 10% glycerol, 1 mg/mL bovine serum albumin, 1 mM dithiothreitol) and the mixture is incubated for 1 h at RT under with shaking. The kinase reaction is started by the addition of 20 uL/well ATP solution [final concentration: 250 uM ATP, 30 mM Tris-HCl pH 7.5, 0.02% Brij, 0.2 mM sodium orthovanadate, 10 mM magnesium acetate, 0.1 mM EGTA, phosphatase cocktail (Sigma, #P2850, dilution recommended by the manufacturer)] and 10 uL/well MEK1 solution [containing 50 ng biotinylated MEK1 (prepared from purified MEK1 according to standard procedure, e.g. with EZ-Link Sulpho-NHS-LC-Biotin reagent, Pierce, #21335)] and carried out for 60 min at RT with constant shaking. The reaction is stopped by the addition of 12 uL/well of a 100 mM EDTA solution and incubation is continued for a further 5 min. 55 uL/well of the reaction solution are transferred into a streptavidin-coated plate (e.g. Streptawell HighBond, Roche, #11989685001) and shaken gently for 1 h at RT, in order to bind biotinylated MEK1 to the plate. After elimination of the liquid the plate is washed five times with 200 uL/well of 1Ã¿PBS and 100 uL/well solution of primary antibody plus europium-labelled secondary antibody [Anti Phospho-MEK (Ser217/221), Cell Signaling, #9121 and Eu-N1 labelled goat-anti-rabbit antibody, Perkin Elmer, #AD0105] is added, the primary antibody is diluted 1:2000 and the secondary antibody is diluted to 0.4-0.5 ug/mL in Delfia Assay Buffer (Perkin Elmer, #1244-111). After 1 h shaking at RT the solution is poured away and washed five times with 200 uL/well Delfia Wash Buffer (Perkin Elmer, #4010-0010/#1244-114). After the addition of 200 uL/well Enhancement Solution (Perkin Elmer, #4001-0010/#1244-105) the mixture is shaken for 10 min at RT and then measured in a Wallac Victor using the program "Delfia Time Resolved Fluorescence (Europium)".

Assay: Calcium Mobilization Assay: Functional modulation of CXCR4 was determined by calcium mobilization assay using leukemic lymphoid CEM cells, which naturally express high levels of CXCR4. Generally, the assay is carried out as follows: Cells are grown in vitro to confluency. On the day of the assay, cells are removed from the incubator, culture medium removed and replaced with a calcium sensitive dye (Calcium3 assay kit; Molecular Devices, Sunnyvale, Calif.). The cells are allowed to dye load for 45-60 min at 37 °C. in the cell culture incubator and then allowed to equilibrate to room temperature for no more than 15 min before assay. Compound plates were generated containing up to 3% dimethyl sulfoxide in media kept at room temperature. Test compounds were added to the cells at a 1:3 dilution, and calcium mobilization was measured using a Flex Station fluorescence imager (Molecular Devices). This first read was used to determine direct agonist activation of the CXCR4 receptor by the test compounds.

Assay: MGAT LCMS Assay: The MGAT enzyme reactions were performed in CORNING Falcon 96-well Polypropylene plates, in a total volume of 60 uL of 50 mM Potassium Phosphate buffer pH 7.4, containing a final concentration of 100 uM 2-oleoylglycerol, 15 uM oleoyl-Coenzyme A and 0.0013 ug/uL Human or Mouse MGAT-2 or 0.0026 ug/uL Rat recombinant MGAT-2 membranes expressed in Sf9 cells. Assay plates were run through a fully automated robotics system and shaken for 5 seconds every minute for a total 10 minutes. The reactions were then quenched with 120 uL of ice cold methanol containing 1 ug/mL 1,2-distearoyl-rac-glycerol as the internal standard. Plates were shaken for 2 minutes and spun down to remove protein precipitation. After the spin, samples were transferred to LC/MS compatible PCR plates. For LC/MS analysis, a ThermoFisher Surveyor pump, utilizing a Waters Symmetry C8, 50x2.1 mm column, was used for the chromatography of enzyme products.

Assay: PARP Enzyme Inhibition Assay: PARP1 assay was conducted in PARP assay buffer containing 50 mM Tris pH 8.0, 1 mM DTT, 4 mM MgCl2. PARP reactions contained 1.5 uM [3H]-NAD+ (1.6 uCi/mmol), 200 nM biotinylated histone H1, 200 nM sIDNA, and 1 nM PARP enzyme. Auto reactions utilizing SPA bead-based detection were carried out in 100 uL volumes in white 96 well plates. Reactions were initiated by adding 50 ul of 2xNAD+ substrate mixture to 50 uL of 2x enzyme mixture containing PARP and DNA. These reactions were terminated by the addition of 150 uL of 1.5 mM benzamide (~1000-fold over its IC50). 170 uL of the stopped reaction mixtures were transferred to streptavidin Flash Plates, incubated for 1 hour, and counted using a TopCount microplate scintillation counter.
