Assay: Evaluation of Agonistic Activity for Human 5-HT1A Receptor and Human D4 Receptor: Aequorin, Gα16 proteins, and each receptor were transiently expressed in CHO-K1 cell (Chinese hamster ovary), and seeded to 384-well plate. The plate was incubated in a CO2 incubator at 37° C. for 24 hours. Each example compound dissolved in DMSO was added thereto, and the change of luminescence amount was measured with Hamamatsu FDSS/μCELL System (Hamamatsu Photonics). As for the agonistic activity, the maximum activity (Emax) of each compound was calculated on the assumption that the luminescence amount of the well without the compound is 0% and the luminescence amount of the well containing 10 μmol/L endogenous ligand is 100%.

Assay: Enzymatic Assay: Each test compound (10 mM stock in DMSO) is diluted in DMSO to make a 10-point, 3-fold dilution series. 125 nL of each dilution or DMSO alone is dispensed to a 384-well Greiner Lumitrac 200 assay plate using an Echo® Liquid Handler. To each well of the plate is added 20 uL of enzyme in assay buffer or assay buffer alone. Assay buffer consists of 50 mM sodium phosphate, pH 7.0, 50 mM magnesium chloride, 50 mM sodium chloride, and 0.01% (w/v) bovine serum albumin. When present, the R132H mutant IDH1 enzyme is at a working concentration of 1.875 nM (final concentration in assay of 1.5 nM). The assay plate is allowed to incubate for 30 minutes at room temperature and 5 uL of 5× substrate mixture (2.5 uM nicotinamide adenine dinucleotide phosphate, 100 uM adenosine diphosphate, 7.5 mM glyceraldehyde-3-phosphate, 7.5 ug/mL of spinach glyceraldehyde-3-phosphate dehydrogenase, 25 nM phosphoglycerate kinase, and 5 mM alpha-ketoglutarate in assay buffer) is added to all wells. The reaction plate is incubated for 60 minutes followed by addition of 25 uL of Promega Kinase-GLO reagent to all wells and 10-minute incubation.Luminescence is measured using a PerkinElmer Envision plate reader. The percent activity of each dilution is determined as the ratio of background corrected signal to the background corrected signal of wells receiving only DMSO. IC50 values are determined by fitting percent activity data to a four-parameter logistic dose response equation.

Biochemistry. 1994, 33, 14393-14399.) was used as the substrate for Factor D (104 mM). Hydrolysis of this compound by Factor D liberated a free sulfhydryl group which is then reacted with 5,5′-dithiobis(2nitrobenzoic acid) producing an intense yellow color (Habeeb, A. F. S. A. Reaction of protein sulfhydryl groups with Ellman's Reagent. Methods in Enzymol. 1976, 25, 457-464). The assays were performed in 96 well microtiter plates and rates of hydrolysis were monitored at 405 nm on a Biotek Synergy H1 plate reader. Hydrolysis rates were reported as change in mOD/min. The assay was conducted in 100 mM HEPES, 500 mM NaCl, pH 7.5 containing 10% DMSO in a final volume of 50 μL per well.

Assay: Per2 Assay: Compounds were screened by using a high-throughput circadian assay system as previously described in Zhang, E. E. et al. Cell, 2009, 139, 199-210. In brief, stable U20S reporter cells harboring Per2-dLuc were plated at a density of 30,000 cells/well in Corning 96-well, solid white, flat bottom, TC-treated microplates (Corning), and incubated for 48 hours at 37° C. in the presence of 5% CO2 in a medium of Dulbecco's Modified Eagle Medium (DMEM) supplemented with 10% fetal bovine serum (FBS) and penicillin (100 units/mL)-streptomycin (100 μg/mL). Compounds of formula I are solubilized in dimethylsulfoxide (DMSO), typically at a concentration of 2 mg/mL. DMSO stocks are then serially diluted in DMSO, typically diluting 3-fold for each dilution step. Following the 48 h period, cell culture medium is removed from plated cells and cells are synchronized with 200 μL/well of complete cell culture medium (described above), supplemented with 5 μM forskolin (Tocris) and 1 mM beetle luciferin (Promega). Immediately following synchronization, 1 μL of compound dilution is added to each well. Plates are sealed, shaken briefly, and gene expression was monitored by measuring luminescence (Tecan Infinite M200 or Tecan Infinite M200 Pro) continuously for a minimum of 3 days at 35° C. Raw luminescence data (counts) are first analyzed using Multicycle software (Actimetrics, Inc.) to determine the amplitude (amp), period, and phase (phz) for each compound concentration. The period length for control wells (i.e. no compound, DMSO only) should be 26-30 h. Amp data are then plotted against the logarithm compound concentration (M) and analyzed by nonlinear regression analysis to determine the EC50.

Assay: Inhibition of IRAP Assay: Rat epididymal fat pads were homogenized and subjected to ultracentrifugation at 100,000×g for 30 minutes to obtain microsomes containing IRAP. The microsomes (with a total protein content of 55 g/well) were mixed with a solvent (dimethyl sulfoxide; hereinafter, abbreviated as DMSO (final concentration: 0.1%)) or with each test compound (common ratio: 3; maximum concentration: 10 μM). AVP was then added to the solution to a final concentration of 25 μM, and the resulting solution was allowed to react for one hour at 37° C. An aqueous trifluoroacetic acid (hereinafter, abbreviated as TFA) solution was then added to the solution (final concentration: 1%) to stop the enzymatic reaction. Residual AVP was then determined by mass spectrometry (MALDI-MS). Based on the results, IC50 values (nM), i.e. concentrations required for 50% inhibition of decrease in AVP level in the solvent control group, of the individual test compounds were calculated by the logistic regression to evaluate inhibition of IRAP activity. As comparative examples, similar tests were performed with the compounds of the Reference Examples 1 and 2 described below: (2S,3S)-3-amino-2-hydroxy-5-methyl-2-({4-[(trans-4-methylcyclohexyl)oxy]pyridin-2-yl}methyl)hexanoic acid dihydrochloride; and (2S,3R)-3-amino-2-hydroxy-5-methyl-2-({4-[(trans-4-methylcyclohexyl)oxy]pyridin-2-yl}methyl)hexanoic acid hydrochloride, respectively.

Assay: Btk Enzyme Activity Assay: BTK enzymatic activity was determined with the LANCE (Lanthanide Chelate Excite) TR-FRET (Time-resolved fluorescence resonance energy transfer) assay. In this assay, the potency (IC50) of each compound was determined from an eleven point (1:3 serial dilution; final compound concentration range in assay from 1 μM to 0.017 nM) titration curve using the following outlined procedure. To each well of a black non-binding surface Corning 384-well microplate (Corning Catalog #3820), 5 nL of compound (2000 fold dilution in final assay volume of 10 μL) was dispensed, followed by the addition of 7.5 μL of 1× kinase buffer (50 mM Hepes 7.5, 10 mM MgCl2, 0.01% Brij-35, 1 mM EGTA, 0.05% BSA & 1 mM DTT) containing 5.09 pg/μL (66.67 pM) of BTK enzyme (recombinant protein from baculovirus-transfected Sf9 cells: full-length BTK, 6HIS-tag cleaved). Following a 60 minute compound & enzyme incubation, each reaction was initiated by the addition of 2.5 μL 1× kinase buffer containing 8 μM biotinylated A5 peptide (Biotin-EQEDEPEGDYFEWLE-NH2) (SEQ.ID.NO.: 1), and 100 μM ATP. The final reaction in each well of 10 μL consists of 50 pM hBTK, 2 μM biotin-A5-peptide, and 25 μM ATP. Phosphorylation reactions were allowed to proceed for 120 minutes. Reactions were immediately quenched by the addition of 20 uL of 1× quench buffer (15 mM EDTA, 25 mM Hepes 7.3, and 0.1% Triton X-100) containing detection reagents (0.626 nM of LANCE-Eu-W1024-anti-phosphoTyrosine antibody, PerkinElmer and 86.8 nM of Streptavidin-conjugated Dylight 650, Dyomics/ThermoFisher Scientific). After 60 minutes incubation with detection reagents, reaction plates were read on a PerkinElmer EnVision plate reader using standard TR-FRET protocol. Briefly, excitation of donor molecules (Eu-chelate:anti-phospho-antibody) with a laser light source at 337 nm produces energy that can be transferred to Dylight-650 acceptor molecules if this donor:acceptor pair is within close proximity Fluorescence intensity at both 665 nm (acceptor) and 615 nm (donor) are measured and a TR-FRET ratio calculated for each well (acceptor intensity/donor intensity). IC50 values were determined by 4 parameter robust fit of TR-FRET ratio values vs. (Log10)) compound concentrations.

Assay: Fluorescence Polarization (FP) Competitive Binding Assay: A fluorescence polarization (FP) competitive binding assay was used to determine the binding affinities of representative menin inhibitors. A FAM labeled fluorescent probe was designed and synthesized based on a MLL1 peptide (FAM-MM2). Equilibrium dissociation constant (Kd) value of FAM-MM2 to menin protein was determined from protein saturation experiments by monitoring the total fluorescence polarization of mixtures composed with the fluorescent probe at a fixed concentration and the protein with increasing concentrations up to full saturation. Serial dilutions of the protein were mixed with FAM-MM2 to a final volume of 200 μl in the assay buffer (PBS with 0.02% Bovine γ-Globulin and 4% DMSO. 0.01% Triton X-100 was added right before assays). Final FAM-MM2 concentration was 2 nM. Plates were incubated at room temperature for 30 minutes with gentle shaking to assure equilibrium. FP values in millipolarization units (mP) were measured using the Infinite M-1000 plate reader (Tecan U.S., Research Triangle Park, N.C.) in Microfluor 1 96-well, black, v-bottom plates (Thermo Scientific, Waltham, Mash.) at an excitation wavelength of 485 nm and an emission wavelength of 530 nm. Kd value of FAM-MM2, which was calculated by fitting the sigmoidal dose-dependent FP increases as a function of protein concentrations using Graphpad Prism 6.0 software (Graphpad Software, San Diego, Calif.), is determined as 1.4 nM.

The plate was placed in High-Throughput Screening System FDSS 3000 (Hamamatsu Photonics K.K.). Measurement of fluorescence intensity by FDSS 3000 was started, and 40 μl, of DMSO solutions containing different concentrations of the test, compound as prepared by dilution with dilution buffer (20 mM HEPES, 137 mM NaCl, 2.7 mM KCl, 0.9 mM MgCl2, 5.0 mM CaCl2, 5.6 mM D-glucose, 2.5 mM probenecid, 0.1.% Pluronic F-127, pH 7.5) were dispensed to each well through the built-in automatic dispenser. Five minutes after, 50 nM ATP solution (50 μL) prepared by dilution with the dilution buffer was dispensed through the built-in automatic dispenser, and the measurement of fluorescence intensity was continued for 3 min. For each well, the specific maximum fluorescence intensity was calculated as the ratio of the maximum fluorescence intensity after addition of the ATP solution to the fluorescence intensity at the starting of the measurement. The 50% inhibitory concentration (IC50) was calculated under the assumption that the specific maximum fluorescence intensity without test compound is 0% inhibition and that the specific maximum fluorescence intensity when the dilution buffer was added in place of ATP solution is 100% inhibition, to evaluate the inhibitory activity of the test compound. FDSS software (Hamamatsu Photonics K.K.) was used for calculation of the specific maximum fluorescence intensity. IC50 was calculated using Microsoft Excel (Microsoft Corporation) and Ltd.).
