Assay: Inhibition Assay of PI3K: An exemplary system is PI 3-Kinase (human) HTRF Assay from Upstate. The assay can be carried out according to the procedures suggested by the manufacturer. Briefly, the assay is a time resolved FRET assay that indirectly measures PIP3 product formed by the activity of a PI3-K. The kinase reaction is performed in a microtitre plate (e.g., a 384 well microtitre plate). The total reaction volume is approximately 20 ul per well. In the first step, each well receives 2 ul of test compound in 20% dimethylsulphoxide resulting in a 2% DMSO final concentration. Next, approximately 14.5 ul of a kinase/PIP2 mixture (diluted in 1× reaction buffer) is added per well for a final concentration of 0.25-0.3 ug/ml kinase and 10 μM PIP2. The plate is sealed and incubated for 15 minutes at room temperature. To start the reaction, 3.5 ul of ATP (diluted in 1× reaction buffer) is added per well for a final concentration of 10 μM ATP. The plate is sealed and incubated for 1 hour at room temperature. The reaction is stopped by adding 5 ul of Stop Solution per well and then 5 ul of Detection Mix is added per well. The plate is sealed, incubated for 1 hour at room temperature, and then read on an appropriate plate reader.

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.

Target: Tyrosine-protein kinase Lyn (SINGLE PROTEIN), Homo sapiens
UniProt: P07948
Assay: Lyn Enzyme Activity : Lyn enzyme activity is measured using the IMAP (immobilized metal ion affinity-based fluorescence polarization) assay as outlined below.Lyn enzyme (Millipore catalog #14-510), is diluted to 250 mU/mL in KR buffer (10 mM Tris-HCl, 10 mM MgCl2, 0.01% Tween-20, 0.05% NaN3, 1 mM DTT, 2 mM MnCl2, pH 7.2).Serial dilution log 10 from 2 mM to 63.2 nM of test compounds are made in 100% DMSO. The dilutions in DMSO are then diluted 50-fold in KR-buffer of which 5 μl is used in the assay, leading to a final compound concentration range in the assay from 10 μM to 0.316 nM.5 μL/well of test compound in KR buffer (final DMSO concentration in the assay is 1%) is mixed with 5 μl/well of 250 mU/mL Lyn enzyme (final concentration in the assay is 62.5 mU/mL). Test compounds and Lyn enzyme are pre-incubated 60 minutes at room temperature, before adding 5 μL/well of 400 nM Fluorescin labeled substrate peptide (Blk/Lyntide substrate, e.g. #R7188/#R7233, Molecular Devices) in KR-buffer. Final peptide substrate concentration in assay is 100 nM. The kinase assay is started by adding 5 μL/well of 8 μM ATP in KR-buffer (final ATP concentration is 2 μM ATP, Km ATP in Lyn IMAP assay). Following incubation for 2 h at room temperature the enzyme reaction is stopped by adding 40 μL/well IMAP Progressive Binding Solution (according to suppliers (Molecular Devices) protocol using 75% 1× buffer A and 25% 1× buffer B with 1:600 Progressive Binding Solution). After 60 min incubation at room temperature in the dark the FP signal is read. Fluorescence at 535 nm is measured using parallel and perpendicular filters to determine differences in rotation due to binding of the phosphorylated substrate peptide to the beads. Values are calculated as percentage of the difference in readout (ΔmPi) of the controls with and without ATP. EC50 values are determined by curve fitting of the experimental results using Activity Base.

Assay: 5-HT2C Receptor Binding Assay: A solution of 200 μL in total was prepared by mixing 50 μL of [3H] mesulergine (manufactured by GE Healthcare) diluted with 50 mmol/L Tris-HCl (pH=7.4) (final concentration: about 2 nmol/L), 149 μL of the h-5-HT2C/CHO membrane preparation (protein amount: 20 μg/well), and 1 μL of the test drug dissolved in dimethylsulfoxide. The solution was reacted at 37° C. for 30 minutes, and then quickly suction-filtered under reduced pressure through a glass fiber filter coated with 1% aq. bovine serum albumin. The glass fiber filter was washed twice with 250 μL of 50 mmol/L Tris-HCl (pH=7.4), placed in a plastic vial containing 4 mL of liquid scintillator (ACS-II, manufactured by Amersham) or Ecoscint A (manufactured by National Diagnostics), and the remaining radioactivity on the filter paper was assayed with a liquid scintillation counter. The non-specific binding of [3H] mesulergine was defined as a binding amount in the presence of 10 μmol/L SB206553 (manufactured by Sigma Aldrich). The IC50 value was calculated according to Hill analysis, and the binding inhibition constant (Ki) was calculated according to the following formula: Binding inhibition constant (Ki)=IC50/(1+S/Kd) wherein S is a concentration of the added [3H] mesulergine, and Kd is a binding dissociation constant of [3H] mesulergine which was calculated from a saturated binding assay using the same cell membrane. A lower Ki value (i.e. a lower 5-HT2C binding inhibition constant) means that the test drug has a higher affinity for human serotonin reuptake inhibitory action.

Target: Glutamate NMDA receptor; GRIN1/GRIN2B (PROTEIN COMPLEX), Homo sapiens
UniProt: Q13224
Assay: NMDA receptor FLIPR assay: NMDA receptors are ion channels that are highly permeable to Ca2+ ions, rendering it possible to monitor NMDA receptor function using cell-based calcium flux assay. In this assay, co-agonists glutamate and glycine are added to cells heterologously expressing human GluN1/GluN2B NMDA receptors to initiate cellular Ca2+ influx. The time course of the changes in intracellular calcium is measured using a fluorescent dye and a FLIPR (Fluorometric Imaging Plate Reader) device.Twenty four hours before measurements, the expression of the NMDA receptors in the stable cell line is induced with Tet-On inducible system in the presence of a non-selective NMDA receptor blocker. On the day of the experiment, cell culture media is carefully washed and the cells are loaded with Calcium 5 Dye Kit (Molecular Devices) in dye loading buffer containing 149 mM NaCl, 4 mM KCl, 2 mM CaCl2, and 1.5 mM MgCl2, 10 mM HEPES and 5 mM D-glucose; pH 7.4. After 1 h incubation at the room temperature, the dye is washed away with the assay buffer (149 mM NaCl (standard assay) or 150 mM (HTS assay), 4 mM KCl (standard assay) or 3 mM (HTS assay), 2 mM CaCl2, 0.01 mM EDTA, 10 mM HEPES and 5 mM D-glucose; pH 7.4) In the FLIPR TETRA reader, various concentrations of the test compounds are added to the cells for 5 min while fluorescence is monitored to detect potential agonist activity. Next, co-agonists, glutamate and glycine are added for another 5 minutes. The concentration of glutamate corresponding to EC80 (standard assay) or EC40 (HTS assay) is used to maximize the assay's signal window or the ability to detect NMDA receptor antagonists and negative allosteric modulators, respectively. A saturating concentration (10 μM) of glycine is also present in the assay. A non-selective NMDA receptor antagonist, (+)MK-801 is used as a positive control for antagonist activity. The fluorescent signal in the presence of test compounds is quantified and normalized to the signal defined by the appropriate control wells.
