Assay: NAMPT Enzyme Assay: To measure the inhibition of NAMPT activity hNAMPT protein stock and anti 6His-Tb (Cisbio; Cat. No. 61HISTLB) is diluted to 3× final concentration with assay buffer (50 mM Tris-HCl (pH7.5), 1 mM DTT, 100 mM NaCl, 10 mM MgCl2, 0.005% Tween 20). To this solution is added test compounds or vehicle control (DMSO) and BodiPY ligand (structure below). The plate is shaken for 1-2 min, sealed and incubated for 1 hour at rt in the dark. The TR-FRET signal is measured using BMG Pherastar (Lanthascreen protocol on BMG Pherastar). Excitation was carried out at 320 nm, and the ratio of emission of BodiPY (520 nm) to terbium (486 nm) was determined. Concentration response curves are generated by calculating the excitation increase in test compound-treated samples relative to DMSO-treated controls. For the assay method described above, test compound percent inhibition values at a single concentration are calculated relative to control (DMSO) treated samples. Compound concentration response curves are fitted to generate IC50 values from those curves. One skilled in the art will appreciate that these values generated either as percentage inhibition at a single concentration or IC50 values are subject to experimental variation.

Assay: Enzyme Activity: Determination of IC50 : The Class B enzyme activities were measured in the presence of the test inhibitor in a fluorescence assay against a commercially available substrate consisting of a cephalosporin core linking 7-hydroxycoumarin to fluorescein (CCF2-FA). The enzyme (NDM-1, IMP-1 or VIM-1) and the substrate were diluted in 100 mM KH2PO4 buffer (pH 7) containing 0.005% Tween-20 and 10 μM ZnSO4. In the assay, the final concentration of enzyme was 1 pM, 2 pM and 30 pM for NDM-1, IMP-1 and VIM-1, respectively, and the final concentration of CCF2-FA was 1.25 μM. The test inhibitor was dissolved in dimethylsulfoxide and diluted 1:50 in the assay, resulting in a final concentration range of 20 μM to 0.00063 μM. In a 384-well microplate, the test inhibitor was incubated with the metallo-β-lactamase enzyme and the substrate for 2 hours at 25° C. Fluorescence at 460 nm following excitation at 405 nm was measured. The IC50 value was determined from semi-logarithmic plots of enzyme inhibition versus inhibitor concentration, with a curve generated using a 4-parameter fit.

Assay: TYK2 JH2 Domain Binding Assay: The binding reaction was assembled by combining 16 μl of DNA-tagged kinase extract, 3.8 μl liganded affinity beads, and 0.18 μl test compound (PBS/0.05% Tween 20/10 mM DTT/0.1% BSA/2 μg/ml sonicated salmon sperm DNA)]. Extracts were used directly in binding assays without any enzyme purification steps at a ≥10,000-fold overall stock dilution (final DNA-tagged enzyme concentration <0.1 nM). Extracts were loaded with DNA-tag and diluted into the binding reaction in a two step process. First extracts were diluted 1:100 in 1× binding buffer (PBS/0.05% Tween 20/10 mM DTT/0.1% BSA/2 μg/ml sonicated salmon sperm DNA) containing 10 nM DNA-tag. This dilution was allowed to equilibrate at room temperature for 15 minutes and then subsequently diluted 1:100 in 1× binding buffer. Test compounds were prepared as 111× stocks in 100% DMSO. Kds were determined using an 11-point 3-fold compound dilution series with three DMSO control points. All compounds for Kd measurements are distributed by acoustic transfer (non-contact dispensing) in 100% DMSO

Assay: Luciferase Reporter Gene Assay for ALK2 and TGFbeta Activity: In this reporter gene cell based ALK2 and TGFβ assay, the C2Cl2 cell line was employed for the measurement of ALK2 activity, using a BRE-Luc SMAD1/5/8 reporter and BMP6 as the agonist. The HEK293T cell line was employed to measure TGFβ activity, using a SBE-Luc SMAD2/3 reporter and TGFβ as the agonist. Luciferase reporter assays were read using Promega Steady-Glo Luciferase Assay System.Cells were plated in 96 well white clear bottom assay plates at 10 k cells/well for C2Cl2-BRE, 15 k cells/well for HEK293-SBE in DMEM containing 2% FBS 1% P/S. Cells were given a minimum of 4 hours in incubator at 37° C./5% CO2 to adhere prior to further treatment. Compounds were diluted in DMSO to a 10-point dilution curve and added to the plate to reach the following final concentrations: 10000, 3000, 1000, 300, 100, and 30 nM in the HEK293-SBE assay and 1000, 300, 100, 30, 10, 3, 1, 0.3 nM in the C2Cl2-BRE assay. Negative and positive control wells received 2 μL DMSO as vehicle treatment. Plates were returned to incubator for 45 minutes and then BMP6 and TGFB were added to a final concentration of 50 ng/mL and 5 ng/mL, respectively. Plates were returned to the incubator and left overnight. After a minimum of 18 hours post BMP6/TGFβ addition, the plates were read using Promega Steady-Glo Luciferase Assay System. A 1:1 mixture of prepared steady-glo and phenol free DMEM was prepared, and 50 μL/well was added to the assay plates whose media had been flicked off. Plates were given 10 minutes post steady-glo addition before luminescence was read on a Spectramax M5e microplate reader. Negative control wells were averaged and subtracted from all other wells on the plate. Inhibition was calculated as the percent of signal loss compared to the averaged positive control wells.

In assay buffer containing 12.5 mM HEPES pH 7.4, 75 mM NaCl, 1 mM MgCl2, 1 mM BME, 5 uM Cyclophilin A and 2 uM test compound, a 5 uM stock of GMP-PNP-loaded K-Ras (1-169) G12C is diluted 10-fold to yield a final concentration of 0.5 uM; with final sample volume being 100 uL. The sample is incubated at 25�� C. for a time period of up to 24 hours prior to quenching by the addition of 10 uL of 5% Formic Acid. Quenched samples are centrifuged at 15000 rpm for 15 minutes in a benchtop centrifuge before injecting a 10 uL aliquot onto a reverse phase C4 column and eluting into the mass spectrometer with an increasing acetonitrile gradient in the mobile phase. Analysis of raw data may be carried out using Waters MassLynx MS software, with % bound calculated from the deconvoluted protein peaks for labeled and unlabeled K-Ras.

Assay: SHP2 Allosteric Inhibition Assay: SHP2 is allosterically activated through binding of bis-tyrosyl-phorphorylated peptides to its Src Homology 2 (SH2) domains. The latter activation step leads to the release of the auto-inhibitory interface of SHP2, which in turn renders the SHP2 protein tyrosine phosphatase (PTP) active and available for substrate recognition and reaction catalysis. The catalytic activity of SHP2 was monitored using the surrogate substrate DiFMUP in a prompt fluorescence assay format.<p id="p-0219" num="0218">More specifically, the phosphatase reactions were performed at room temperature in 96-well black polystyrene plate, flat bottom, low flange, non-binding surface (Corning, Cat #3575) using a final reaction volume of 50 μl and the following assay buffer conditions: 60 mM HEPES, pH 7.2, 75 mM NaCl, 75 mM KCl, 1 mM EDTA 0.005% Brij-35, 5 mM DTT. The inhibition of SHP2 by compounds of the disclosure (concentrations varying from 0.003-100 μM) was monitored using an assay in which 0.25 nM of SHP2 was incubated with of 0.5 μM of peptide IRSl_pY1172(dPEG8)pY1222 (sequence: H2N-LN(pY)IDLDLV(dPEG8)LST(pY)ASINFQK-amide). After 30-60 minutes incubation at 25° C. the surrogate substrate DiFMUP (Invitrogen, cat #D6567, 100 μM final) was added to the reaction and the conversion of DiFMUP to 6,8-difluoro-7-hydroxyl-4-methylcoumarin (DiFMU) was monitored continuously for 10 minutes with excitation at 355 nm and emission at 460 nm using a microplate reader (PolarStar, BMG).

Assay: Biochemical Assay: The purpose of CDK2/Cyclin E1 assay is to evaluate the inhibition (% inhibition, Kiapp and Ki values) of small molecule inhibitors by using a fluorescence-based microfluidic mobility shift assay. CDK2/Cyclin E1 full length catalyzes the production of ADP from ATP that accompanies the phosphoryl transfer to the substrate peptide FL-Peptide-18 (5-FAM-QSPKKG-CONH2, CPC Scientific, Sunnyvale, Calif.) (SEQ ID NO:1). The mobility shift assay electrophoretically separates the fluorescently labeled peptides (substrate and phosphorylated product) following the kinase reaction. Both substrate and product are measured and the ratio of these values is used to generate % conversion of substrate to product by the LabChip EZ Reader. Wild-type CDK2/wild-type full length Cyclin E1 enzyme complex was produced in-house (baculoviral expression, LJIC-2080/LJIC-2103) and phosphorylated by CDK7/Cyclin H1/Matl enzyme complex with CDK2:CDK7 ratio of 50:1 (concentration mg/mL) in the presence of 10 mM MgCl2 and 5 mM ATP at room temperature for one hour. Typical reaction solutions (50 μL final reaction volume) contained 2% DMSO (±inhibitor), 4 mM MgCl2, 1 mM DTT, 150 μM ATP (ATP Km=67.4 μM), 0.005% Tween-20, 3 μM FL-Peptide-18, and 0.36 nM (catalytically competent active site) phosphorylated wild-type full length CDK2/Cyclin E1 enzyme complex in 25 mM HEPES buffer at pH 7.15. The assay was initiated with the addition of ATP, following a fifteen minutes pre-incubation of enzyme and inhibitor at room temperature in the reaction mixture. The reaction was stopped after 45 minutes at room temperature by the addition of 50 μL of 80 mM EDTA.

Assay: Fluorescence Polarization Assay: eIF4E protein was pre-incubated with EDA-m7GDP-ATTO-550 in FPB at 2xconcentrations for 5 minutes prior to the addition of compounds. Compounds (100x) were prepared using 3-fold serial dilutions in 100% DMSO, and subsequently diluted 1:50 in FPB to produce 2x stocks. 50 ul of 2x eIF4E/EDA-m7GDP-ATTO-550 were transferred to the wells of a 96-well half-area black flat bottom polystyrene plate. 50 ul of 2x test compound were added, and binding reactions were allowed to equilibrate for 30 minutes at room temperature while protected from light. The fluorescent polarization signal was detected using a Victor 2 multi-label counter (Perkin Elmer) and the concentration necessary to achieve inhibition of eIF4E/EDA-m7GDP-ATTO-550 binding by 50% (IC50) was calculated using data from an 8-point compound dilution series.

Assay: Inhibition Test for Each Compound of the Present Invention Against 20-HETE Producing Enzymes (CYP4F2 and CYP4A11): In the CYP4F2 inhibition test, the reaction solution containing each compound [final concentration of 50 mM, KPO4 (pH 7.4), 2.5 μM luciferine derivative, and 1 mM NADPH] was added to an Escherichia coli membrane fraction (100 μg/mL protein) in which human CYP4F2 had been expressed. In the CYP4A11 inhibition test, the reaction solution containing each compound [final concentration of 100 mM, Tris-HCl (pH 7.5), 60 μM luciferine derivative, 1.3 mM NADP+, 3.3 mM Glucose 6-Phosphate, 3.3 mM MgCl2, and 0.4 U/mL Glucose 6-Phosphate dehydrogenase] was added to an Escherichia coli membrane fraction (100 μg/mL protein) in which human CYP4A11 had been expressed. Following this, the membrane fraction was left to stand at room temperature for 60 minutes to perform an enzymatic reaction. After the reaction, a luciferine detection reagent was added, and the luminescence value was measured using a plate reader. By using that value, the percent inhibition of 20-HETE producing enzyme (%) was calculated according to the equation described below, and the 50% inhibitory concentration (IC50 value) for each compound was calculated.

Assay: In Vitro CBP Inhibition: The CBP-inhibitory activity of the compounds described herein was determined by calculating the IC50. More specifically, CBP inhibitor activity was assayed as follows: CBP was cloned and expressed in E. coli as His-tag protein and purified by Nickel affinity and gel-filtration chromatography. The protein was further characterized as a single band with the correct molecular weight by SDS-PAGE. CBP binding and inhibition is assessed by monitoring the interaction of biotinylated H4-tetraacetyl peptide (AnaSpec, H4K5/8/12/16(Ac), biotin-labeled) with the target using the AlphaScreen technology (Perkin Elmer). In a 384-well ProxiPlate CBP (50 nM final) was combined with peptide (20 nM final) in 50 mM HEPES (pH 7.3), 10 mM NaCl, 0.25 mM TCEP, 0.1% (w/v) BSA, and 0.005% (w/v) Brij-35 either in the presence of DMSO (final 0.4% DMSO) or compound dilution series in DMSO. After 20 min incubation at room temp, Alpha-streptavidin donor beads and Nickel Chelate acceptor beads were added to a final concentration of 5 μg/mL. After 2 hr of equilibration, plates were read on an Envision instrument and the IC50 calculated using a four parameter non-linear curve fit.
