Assay: Inhibition of Tautomerase Activity of Human MIF: Inhibition of the tautomerase activity of MIF was measured using 4-hydroxyphenyl pyruvic acid (HPP) as substrate, largely following previously reported protocols (Taylor et al., Biochemistry, 1999, 38, 7444-7452). HPP was dissolved in 0.5 M acetate buffer, pH 6.0 to a final concentration of 10 mM and incubated overnight at room temperature to allow equilibration of the keto and enol forms. MIF (6 μL) was premixed in 500 mM boric acid, pH 6.2 (142 μL) and transferred to a transparent U bottom 96-well plate to a final concentration of 50 nM MIF. At this concentration high signal-to-noise and linearity were observed after analysis of progress curves for enol production at different protein concentrations. Inhibitors were dissolved in DMSO to 10 mM and an initial screen was performed. For compounds that showed ca. 25% or greater inhibition at 10 μM, an inhibition constant, was measured.Compounds were placed into wells (2 μL) at 6 different concentrations and incubated for 30 minutes until the assay was started by addition of HPP (504) at two concentrations (1.0 and 2.5 mM). The negative control was MIF incubated with DMSO vehicle, which in all assays was 1% and did not influence tautomerase activity. MIF activity was monitored at 305 nm for formation of the borate-enol complex using an Infinite F500 plate reader (TECAN, Morrisville, N.C.) for 175 seconds. Calculation of initial velocities and the nonlinear regression analyses for the enzyme kinetics were repeated three times with the program Prism6 (GraphPad, La Jolla, Calif.).Data obtained for the Example compounds, obtained using the methods described in Example B, are provided in Table 3. Results are also included for a reference compound ISO-1 (Chang, K. F.; Al-Abed, Y. Bioorg. Med. Chem. Lett. 2006, 16, 3376-3379; Balachandran, S. et al. Bioorg. Med. Chem. Lett. 2009, 19, 4773-4776). X-ray crystal structures were obtained for complexes of 3a, 3b, and 3v (Examples 1, 2, and 21) with human MIF as described below in Example C, which confirm the binding of these inhibitors in the tautomerase active site.

Assay: PI3-Kinase HTRF Assay: A PI3-Kinase HTRF® assay kit (cat No. 33-016) purchased from Millipore Corporation is used to screen compounds provided herein. This assay uses specific, high affinity binding of the GRP1 pleckstrin homology (PH) domain to PIP3, the product of a Class 1A or 1B PI3 Kinase acting on its physiological substrate PIP2. During the detection phase of the assay, a complex is generated between the GST-tagged PH domain and biotinylated short chain PIP3. The biotinylated PIP3 and the GST-tagged PH domain recruited fluorophores (Streptavidin-Allophycocyanin and Europium-labeled anti-GST respectively) to form the fluorescence resonance energy transfer (FRET) architecture, generating a stable time-resolved FRET signal. The FRET complex is disrupted in a competitive manner by non-biotinylated PIP3, a product formed in the PI3 Kinase assay.PI3 Kinase α, γ or δ activity is assayed using the PI3 Kinase HTRF® assay kit (catalogue No. 33-016) purchased from Millipore Corporation. Purified recombinant PI3Kα (catalogue No. 14-602-K), PI3Kβ (catalogue No. 14-603-K), PI3Kγ (catalogue No. 14-558-K), and PI3Kδ (catalogue No. 14-604-K) are obtained from Millipore Corporation. Purified recombinant PI3K enzyme is used to catalyze the phosphorylation of phosphatidylinositol 4,5-bisphosphate (PIP2 at 10 μM) to phosphatidylinositol 3,4,5-trisphosphate (PIP3) in the presence of 10 μM ATP. The assay is carried out in 384-well format and detected using a Perkin Elmer EnVision Xcite Multilabel Reader. Emission ratios are converted into percent inhibitions and imported into GraphPad Prism software. The concentration necessary to achieve inhibition of enzyme activity by 50% (IC50) is calculated using concentrations ranging from 20 μM to 0.1 nM (12-point curve). IC50 values are determined using a nonlinear regression model available in GraphPad Prism 5.

Assay: Apoptosis Signal-Regulating Kinase Assay: The assay measures the phosphorylation level of a biotinylated peptide substrate by the ASK1 kinase using HTRF detection. This is a competitive, time-resolved fluorescence resonance energy transfer (TR-FRET) immunoassay, based on HTRF® KinEASE™-STK manual from Cisbio. Test compound, 1 μM STK3 peptide substrate, 4 nM of ASK1 kinase were incubated with 10 mM MOP buffer, pH. 7.0 containing 10 mM Mg-acetate, 0.025% NP-40, 1 mM DTT, 0.05% BSA and 1.5% glycerol for 30 minutes then 100 μM ATP was added to start the kinase reaction and incubated for 3 hr. Peptide antibody labeled with 1× Eu3+ Cryptate buffer containing 10 mM EDTA and 125 nM Streptavidin XL665 were added to stop the reaction and phosphorylated peptide substrate was detected using Envision 2103 Multilabeled reader from PerkinElmer. The fluorescence was measured at 615 nm (Cryptate) and 665 nm (XL665) and a ratio of 665 nm/615 nm was calculated for each well. The resulting TR-FRET level (a ratio of 665 nm/615 nm) was proportional to the phosphorylation level. Under these assay conditions, the degree of phosphorylation of peptide substrate was linear with time and concentration for the enzyme.

UniProt: Q86V86
Assay: Enzyme Assay: The assay for the determination of Pim activity is based on the formation of phosphorylated biotinylated-BAD peptide at the Serine 112 residue (S112) and employs HTRF® (homogeneous time resolved fluorescence) technology to detect the product in a 96-well plate format. 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 10-point dosing curve having a high dose of 1 uM. A reference compound was included on each assay plate in order to validate that plate; on

Assay: Heat-Based Assay: CHO cells stably expressing human TRPV1 (hTRPV1) were used. Functional assessment of heat-induced activation of hTRPV1 was carried out in a cell-based Ca2+ flux assay using ABI7500 Fast Real-Time PCR System as described in Reubish et al., "Functional assessment of temperature-gated ion-channel activity using a real-time PCR machine," www.BioTechniques.com 47(3):iii-ix (2009), which is hereby incorporated by reference. Briefly, hTRPV1/CHO cells were cultured in growth media in a tissue culture dish at 37° C. in a CO2 incubator. On the day of the assay, culture media were removed and the cells were then detached using 0.05% trypsin at 37° C. with 5% CO2, for 90 s. The detached cells were centrifuged (1000 rpm, 4 min) to remove trypsin-containing supernatant and resuspended in assay buffer (115 mM NaCl, 5.4 mM KCl, 0.8 mM MgCl2.6H2O, 1.8 mM CaCl2.2H2O, 13.8 mM D-glucose, and 20 mM HEPES). Then, the cells were loaded with 5 μM Fluo-4, a Ca2+ reporter dye, in the presence of 2.5 mM probenecid at 37° C. with 5% CO2, for 45 min. Thereafter, the cells were washed twice with measuring buffer (assay buffer supplemented with 0.1% BSA and 3.2 mM CaCl2) then transferred to a Fast 96-well Reaction Plate (0.1 mL) (Part no. 4346907, MICROAMP, Applied Biosystems, Foster City, Calif.). The cell density was 100,000 cells/24 μL/well. A solution of the compound under test (6 μL/well) was added into each well of the 96-well plate. Thus, the reaction volume per well was 30 μL. The plates were then placed inside an ABI7500 Fast Real-Time PCR instrument (Applied Biosystems) to read fluorescence at different temperatures using 7500 software, version 2.0.2 (Applied Biosystems). The initial temperature was set at 25° C. for 1 min. followed by a temperature ramp to 45° C. in 100 s to deliver heat to cells.

Assay: In Vitro Assay: On day of the assay, 100 uL of 0.05% CHAPS (in deionized H2O) was added to all wells of the GFB Unifilter plate and allowed soak for 1 h. A wash buffer of 50 mM HEPES (pH 7.4), 150 mM NaCl, and 5 mM MgCl2 was prepared to wash the filter plate. To prepare an assay buffer, BSA was added to the wash buffer to reach 0.01% and DTT was added to reach 1 mM. For IC50 mode, 10 mM compound stocks were serially diluted in DMSO with DMSO to give 20x required final concentration in DMSO (15 uL compound+30 uL DMSO). The 20x compound stocks were diluted in DMSO with Assay Buffer 4-fold to reach 5x the final test concentration in 25% DMSO (10 uL compound+30 uL Assay Buffer). Solutions were mixed by aspiration several times with a pipette set on 50 uL volume. For the assay, 10 uL of 5x compound stock solutions in 25% DMSO were added to the assay plate in duplicate.
