Target: Metabotropic glutamate receptor 8 (SINGLE PROTEIN), Rattus norvegicus
UniProt: P70579
Assay: Pharmacological Assay: Metabotropic glutamate receptors were transiently transfected in HEK293 cells by electroporation as described elsewhere (Brabet I. et al., 1998) and plated in 96-well microplates. The high affinity glutamate transporter EAAC1 was co-transfected with the receptor in order to avoid any influence of glutamate released by the cells in the assay medium. In the experiments carried out by the inventors, Group-III mGluRs were co-transfected with a chimeric G-protein which couples the activation of the receptor to the phospholipase-C (PLC) pathway. Thus receptor activation induces production of inositol phosphate (IP) which in turn induces intracellular Ca2+ release. Receptor activity was then determined by measurement of the IP production or Ca release as already described (Goudet C. et al., PNAS 2004). For intracellular calcium measurements, cells expressing mGluRs were loaded with Ca2+-sensitive fluorescent dye Fluo-4 AM (Invitrogen, Cergy-Pontoise, France) dissolved in Hanks' balanced Salt Solution.

Assay: Inhibition Assay: The hERG inhibition study aims at quantifying the in vitro effects of compounds of the invention on the potassium-selective IKr current generated in normoxic conditions in stably transfected HEK 293 cells with the human ether-a-go-go-related gene (hERG). Whole-cell currents (acquisition by manual patch-clamp) elicited during a voltage pulse were recorded in baseline conditions and following application of tested compounds (5 minutes of exposure). The concentrations of tested compounds (0.3 μM; 3 μM; 10 μM; 30 μM) reflect a range believed to exceed the concentrations at expected efficacy doses in preclinical models. The pulses protocol applied is described as follow: the holding potential (every 3 seconds) was stepped from −80 mV to a maximum value of +40 mV, starting with −40 mV, in eight increments of +10 mV, for a period of 1 second. The membrane potential was then returned to −55 mV, after each of these incremented steps, for 1 second and finally repolarized to −80 mV for 1 second.

The concentration of 2-HG in the resulting supernatants was measured by LC-MS (see below).LC-MS method. Reaction mixture supernatants were submitted to chromatographic separation on a BiobasicAX column (2.1 mm×20 mm, 5 μm particle, Thermo Scientific Inc.). The chromatographic mobile phases were A) 25 mM ammonium biocarbonate and B) acetonitrile (0.1% ammonium hydroxide). Nicotinamide was eluted at 1 ml/min using a 85-5% B gradient over 0.9 minutes (Agilent 1200SL LC system, Thermofisher LX-4 autosampler) and analyzed by multiple reaction monitoring (MRM) on a API4000 QTrap mass spectrometer (ABSciex, Framingham, Mass.) in the positive electrospray ionization (ESI+) mode. The mass transition for 2-HG and 13C-2-HG were 147→129 and 152→134, respectively. The relative responses (2-HG/13C-2-HG) were measured at varied inhibitor concentrations and used to calculate inhibitory IC50 values (normalized IC50 regression curves).

Assay: Measurement of FXIa Inhibition: To determine the factor XIa inhibition of the substances according to the invention, a biochemical test system is used which utilizes the reaction of a peptidic factor XIa substrate to determine the enzymatic activity of human factor XIa. Here, factor XIa cleaves from the peptic factor XIa substrate the C-terminal aminomethylcoumarin (AMC), the fluorescence of which is measured. The determinations are carried out in microtitre plates.Test substances are dissolved in dimethyl sulphoxide and serially diluted in dimethyl sulphoxide (3000 μM to 0.0078 μM; resulting final concentrations in the test: 50 μM to 0.00013 μM). In each case 1 μl of the diluted substance solutions are placed into the wells of white microtitre plates from Greiner (384 wells). 20 μl of assay buffer (50 mM of Tris/HCl pH 7.4; 100 mM of sodium chloride solution; 5 mM of calcium chloride solution; 0.1% of bovine serum albumin) and 20 μl of factor XIa from Kordia (0.45 nM in assay buffer) are then added successively. After 15 min of incubation, the enzyme reaction is started by addition of 20 μl of the factor XIa substrate Boc-Glu(OBzl)-Ala-Arg-AMC dissolved in assay buffer (10 μM in assay buffer) from Bachem, the mixture is incubated at room temperature (22° C.) for 30 min and fluorescence is then measured (excitation: 360 nm, emission: 460 nm). The measured emissions of the test batches with test substance are compared to those of control batches without test substance (only dimethyl sulphoxide instead of test substance in dimethyl sulphoxide), and the IC50 values are calculated from the concentration/activity relationships.

Assay: Fluorescence-Based (Inhibitor)-Screening Assay: In order to monitor MAO enzymatic activities and/or their inhibition rate by inhibitor(s) of interest, a fluorescence-based (inhibitor)-screening assay was set up. 3-(2-Aminophenyl)-3-oxopropanamine (kynuramine dihydrobromide, Sigma Aldrich), a non fluorescent compound was chosen as a substrate. Kynuramine is a non-specific substrate for both MAO-A and MAO-B activities. While undergoing oxidative deamination by MAO activities, kynuramine is converted into 4-hydroxyquinoline (4-HQ), a resulting fluorescent product.The monoamine oxidase activity was estimated by measuring the conversion of kynuramine into 4-hydroxyquinoline. Assays were conducted in 96-well black plates with clear bottom (Corning) in a final volume of 100 uL. The assay buffer was 100 mM HEPES, pH 7.5. Each experiment was performed in duplicate within the same experiment.Briefly, a fixed amount of MAO (0.25 ug for MAO-A and 0.5 ug for MAO-B) was incubated on ice for 15 minutes in the reaction buffer, in the absence and/or in the presence of at least eight 3-fold serial dilutions each. Clorgyline and Deprenyl (Sigma Aldrich) was used as a control for specific inhibition of MAO-A and MAO-B respectively. After leaving the enzyme(s) interacting with the inhibitor, KM of kynuramine was added to each reaction for MAO-B and MAO-A assay respectively, and the reaction was left for 1 hour at 37° C. in the dark. The oxidative deamination of the substrate was stopped by adding 50 uL of NaOH 2N. The conversion of kynuramine to 4-hydroxyquinoline, was monitored by fluorescence (excitation at 320 nm, emission at 360 nm) using a microplate reader (Infinite 200, Tecan). Arbitrary units were used to measure levels of fluorescence produced in the absence and/or in the presence of inhibitor. The maximum of oxidative deamination activity was obtained by measuring the amount of 4-hydroxyquinoline formed from kynuramine deamination in the absence of inhibitor and corrected for background fluorescence in the absence of MAO enzymes. The IC50 values of each inhibitor were calculated with GraphPad Prism Software.

Assay: Inhibition Assay: The hERG inhibition study aims at quantifying the in vitro effects of compounds of the invention on the potassium-selective IKr current generated in normoxic conditions in stably transfected HEK 293 cells with the human ether-a-go-go-related gene (hERG). Whole-cell currents (acquisition by manual patch-clamp) elicited during a voltage pulse were recorded in baseline conditions and following application of tested compounds (5 minutes of exposure). The concentrations of tested compounds (0.3 μM; 3 μM; 10 μM; 30 μM) reflect a range believed to exceed the concentrations at expected efficacy doses in preclinical models. The pulses protocol applied is described as follow: the holding potential (every 3 seconds) was stepped from −80 mV to a maximum value of +40 mV, starting with −40 mV, in eight increments of +10 mV, for a period of 1 second. The membrane potential was then returned to −55 mV, after each of these incremented steps, for 1 second and finally repolarized to −80 mV for 1 second.

Reactions were terminated by rapid filtration onto 96-well Unifilter GF/B filter plates (Perkin Elmer, Shelton, Conn.) using a 96-well tissue harvester (Packard) and followed by three filtration washes with 200 ul ice-cold binding buffer (10 mM NaH2PO4, 10 mM Na2HPO4, pH 7.4). Filter plates were subsequently dried at 50° C. for 1-2 hours.

Target: Cytochrome P450 2C19 (SINGLE PROTEIN), Homo sapiens
UniProt: P33261
Assay: Cytochrome P450 2C9 Inhibition Assay (Mephenytoin): The inhibition of cytochrome P450 2C19-isoenzyme catalysed hydroxylation of Mephenytoin by the test compound is assayed at 37° C. with human liver microsomes. All assays are carried out on a robotic system in 96 well plates. The final incubation volume contains TRIS buffer (0.1 M), MgCl2 (5 mM), human liver microsomes (0.5 mg/ml), (S)-Mephenytoin (70 uM) and the test compound at five different concentrations or no compound (high control) in duplicate (e.g. highest concentration 10-50 uM with subsequent serial 1:4 dilutions). Following a short preincubation period, reactions are started with the cofactor (NADPH, 1 mM) and stopped by cooling the incubation down to 8° C. and subsequently by addition of one volume of acetonitrile.
