Assay: Competition Binding Assay: h-5HT3: In brief, Chinese Hamster Ovary (CHO) cells stably expressing human 5-HT3 serotonin receptors, grown to confluence in 175 cm2 flasks. Following aspiration of the culture medium, cells were harvested by mechanical agitation in ice cold PBS containing (in mM): (150 NaCl, 8 K2HPO4, 2 KH2PO4, pH 7.4, 37° C.), centrifuged at 4,000 g for 10 min and subsequently stored as a cell pellet at −80 C. When required, the pellet was thawed and resuspended in ice cold homogenization buffer (Tris 50 mM, EGTA 5.0 mM, phenylmethylsulphonylfluoride 0.1 mM, pH 7.6) and homogenized. The homogenate was centrifuged at 48,000 g for 10 minutes at 40° C. The resulting pellet was resuspended in ice cold binding buffer comprising (in mM): NaCl 140, KCl 2.8, CaCl2 1.0; MgCl2, 2.0; HEPES 10 (pH 7.4) and centrifuged as above.

Target: Coagulation factor XI (SINGLE PROTEIN), Homo sapiens
UniProt: P03951
Assay: Factor XIa assay : The effectiveness of compounds of the present invention as inhibitors of the coagulation Factors XIa, VIIa, IXa, Xa, XIIa, plasma kallikrein or thrombin, can be determined using a relevant purified serine protease, respectively, and an appropriate synthetic substrate. The rate of hydrolysis of the chromogenic or fluorogenic substrate by the relevant serine protease was measured both in the absence and presence of compounds of the present invention. Hydrolysis of the substrate resulted in the release of pNA (para nitroaniline), which was monitored spectrophotometrically by measuring the increase in absorbance at 405 nm, or the release of AMC (amino methylcoumarin), which was monitored spectrofluorometrically by measuring the increase in emission at 460 nm with excitation at 380 nm. A decrease in the rate of absorbance or fluorescence change in the presence of inhibitor is indicative of enzyme inhibition. Such methods are known to one skilled in the art. The results of this assay are expressed as the inhibitory constant, Ki.Factor XIa determinations were made in 50 mM HEPES buffer at pH 7.4 containing 145 mM NaCl, 5 mM KCl, and 0.1% PEG 8000 (polyethylene glycol; JT Baker or Fisher Scientific). Determinations were made using purified human Factor XIa at a final concentration of 25-200 pM (Haematologic Technologies) and the synthetic substrate S-2366 (pyroGlu-Pro-Arg-pNA; CHROMOGENIX or AnaSpec) at a concentration of 0.0002-0.001 M.

Assay: R132H IDH1 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. The IC50 values of the exemplified compounds are included in the tables above in Examples section.Using the above biological assay, all compounds in the examples have IC50 of about 1 nM to about 40,000 nM, or more specifically, about 1 nM to about 20,000 nM, or even more specifically, about 5 nM to about 15,000 nM, or even more specifically, about 5 nM to about 10,000 nM, or even more specifically, about 5 nM to about 5,000 nM, or still more specifically, about 5 nM to about 1,000 nM.

Each test compound that was diluted with the medium was added to the wells (10 μL/well), wherein each final concentration was adjusted to 0.001, 0.003, 0.01, 0.03, 0.1, 0.3, 1, 3, and 10 μmol/L, or 0.01, 0.03, 0.1, 0.3, 1, 3, 10, 30, and 100 μmol/L. After 0.5 hour, R-848 that is TLR7/8 ligand was added to each well (10 μL/well), wherein each final concentration was adjusted to 200 nmol/L. The total volume was adjusted to 110 μL/well, the test samples were incubated in CO2 incubator for 20±1 hours, and then the SEAP activity was measured as activation of TLR7. The SEAP activity was evaluated as follows: p-nitro-phenyl phosphate (pNPP) (Invitrogen) was added to the incubated sample (50 μL/well); after 15 minutes, 4 mol/L sodium hydroxide solution (nacalai tesque) was added thereto (50 μL/well) to quench the reaction; and the absorbance of each sample was measured at 405 nm with microplate reader Elx808 (BioTek). The 50% inhibitory concentration (IC50 value) of each sample compound was calculated based on 100% of the SEAP activity wherein the test sample comprises no sample compound.

The total volume was adjusted to 110 μL/well, the test samples were incubated in CO2 incubator for 20±1 hours, and then the SEAP activity was measured as activation of TLR7. The SEAP activity was evaluated as follows: p-nitro-phenyl phosphate (pNPP) (Invitrogen) was added to the incubated sample (50 μL/well); after 15 minutes, 4 mol/L sodium hydroxide solution (nacalai tesque) was added thereto (50 μL/well) to quench the reaction; and the absorbance of each sample was measured at 405 nm with microplate reader Elx808 (BioTek). The 50% inhibitory concentration (IC50 value) of each sample compound was calculated based on 100% of the SEAP activity wherein the test sample comprises no sample compound.

Target: Toll-like receptor 7 (SINGLE PROTEIN), Homo sapiens
UniProt: Q9NYK1
Assay: Inhibition of the Activation Assay: As human TLR7 expressing cell line, HEK293 cell line was bought from IMGENEX Corporation (TLR7/NF-ηB/SEAPorter HEK293 cell), which is human embryonic kidney cell line and stably expresses full-length human TLR7 gene and secreted alkaline phosphatase (SEAP) reporter gene under the transcriptional control of an NE-ηB response element. The TLR7/NF-ηB/SEAPorter HEK293 cell was cultivated with DMEM containing 10% fetal bovine serum (FBS) and 10 μg/mL blasticidin S at 37° C. in the presence of 5% CO2. The TLR7/NF-ηB/SEAPorter HEK293 cell was seeded into 96-well microtiter plate at 5×104 cell/90 μL/well, and the place was cultivated at 37° C. in a CO2 incubator overnight. Each test compound that was diluted with the medium was added to the wells (10 μL/well), wherein each final concentration was adjusted to 0.001, 0.003, 0.01, 0.03, 0.1, 0.3, 1, 3, and 10 μmol/L, or 0.01, 0.03, 0.1, 0.3, 1, 3, 10, 30, and 100 μmol/L.
