UniProt: P23458
Assay: HTRF Biochemical Assay: The reactions employed a common peptide substrate, LCB-EQEDEPEGDYFEWLW-NH2 (in-house). The basic assay protocol is as follows: First, 250 nL of diluted compounds in DMSO were dispensed into the wells of a dry 384-well Black plate (Greiner #781076) using a Labcyte Echo 555 acoustic dispenser. Subsequent reagent additions employed an Agilent Bravo. Next, 18 uL of 1.11x enzyme and 1.11x substrate in 1x assay buffer (Invitrogen kinase buffer # PV3189, 2 mM DTT, 0.05% BSA) were added to the wells and shaken and then preincubated for 30 minutes at room temperature to allow compound binding to equilibrate. After equilibration, 2 uL of 10xATP in 1x assay buffer was added to initiate the kinase reaction and the plates were shaken and then incubated at room temperature for 120 minutes. At the end of the incubation, 20 uL of 2x stop buffer (streptavidin-Dylight 650 (Thermo #84547B/100 mL), Eu-tagged pY20 antibody (Perkin Elmer #AD0067), EDTA, HEPES, and Triton) was added to quench the reaction.

Assay: Enzymatic Screening Assay: The enzymatic test is a test in two steps.In a first step, it consists in placing in contact the compound according to the invention, the dialysed MetAP2 protein and the substrate (Met-Pro-Arg-pNa peptide synthesized by Neosystem), the N-terminal methionine of which can be cleaved with MetAP2, and which bears at the C-terminal end a para-nitroaniline (pNa) chromophore, which can itself be released by another peptidase only when the N-terminal methionine has been cleaved beforehand.Consequently, the second step consists in reacting the peptides cleaved in the preceding step with a second peptidase in order to release the chromophore. The peptidase used in this second step is cathepsin, which comes from the TagZyme DAPase kit (Quiagen, 34366).The MetAP2 activity is proportional to the amount of para-nitroaniline released, which is measured by absorbance at 405 nm.

Assay: Inhibition FRET Assay: The Calbiochem InnoZyme activity kit was used for measuring the inhibition effect inhibitors on human erythrocyte calpain 1 activity. A calpain FRET substrate, (DABCYL)-TPLKSPPPSPR-(EDANS) (SEQ ID NO: 9), was used to detect the activity of Cal1. 20 μM of the FRET substrate, 10 nM of native Cal1, and 20 μM TCEP (reducing agent) were added to the reaction mixture containing assay buffer (Tris [10 mM], NaCl [100 mM], pH 7.4). Cal1 was activated by the addition of 10 μM calcium. Cleavage of the scissile bond amide bond, K-S, releases the fluorophore (EDANS) from the internal quenching molecule (DABCYL), resulting in an increase in fluorescence measured at 320 nm excitation and 480 nm emission wave lengths for 30 min. Each inhibitor was added to the reaction mixture at varying concentrations (10 nM, 100 nM, 1 μM, and 10 μM) to detect inhibition of Cal1 and reduction in fluorescence was measured by 96 well-plate reader.

Assay: YO-PRO Assay: HEK cells stably expressing P2X7 were used to screen drugs using the YO-PRO1 assay. Cells were grown to confluency in adherent culture at 37° C. in a humidified 5% CO2 incubator (split ⅕ every 3-4 days with DMEM, 10% FCS, 1% Penicillin/Streptomycin, 250 μg/ml Geneticin). Adherent cells were detached by incubation with Trypsine (1 ml per 165 cm2 dish) for 2 minutes, then washed off with 10 ml PBS (without Mg2+ and Ca2+), and resuspended in DMEM, 10% FCS, 1% Penicillin/Streptomycin, no Geneticin. 10,000 cells per well (48 hours before the assay) or 25,000 cells per well (Vi-cell XR (Beckman Coulter) (24 hours before the assay) in 50 μl full medium were seeded on 384-well black-wall, clear bottom plates, that were coated before with 10 μl per well Poly-L-Lysine, incubated for 30-60 minutes at 37° C. and washed once with PBS. Medium was removed from cells and 50 μl of assay buffer containing 0.5 μM YO-PRO-1 was added into the wells. Solutions of antagonist compounds were prepared by serial dilutions of a 10 mM DMSO solution of the antagonist into PBS using a BioMek (Beckman Coulter). Each concentration was performed in duplicate. For IC50 measurements 10 concentration points were measured (10 μM being the highest concentration followed by 9 serial dilution steps ⅓). The cells were incubated with the antagonists of the present invention together with ATP at a final concentration of 250 μM for 90 minutes. During this time period, four time points were taken. Each time point comprised the average of several measurements made within a few seconds. Fluorescence was measured in the FLIPR tetra (Molecular Devices) using the filters appropriate for YO-PRO-1 fluorescence (excitation485/20, emission 530/25).

UniProt: P49674
Assay: Kinase Assay: The kinase assay was performed in V-bottom 384-well plates. The final assay volume was 30 ul prepared from 15 ul additions of enzyme, substrates (fluoresceinated peptide FL-AHA-KRRRAL-PSER-VASLPGL-OH and ATP) and test compounds in assay buffer (20 mM HEPES pH 7.4, 30 mM MgCl2, 0.015% Brij35 and 4 mM DTT). The reaction was incubated at room temperature for 22 hours and terminated by adding 45 ul of 35 mM EDTA to each sample. The reaction mixture was analyzed on the Caliper LABCHIPÂ®3000 (Caliper, Hopkinton, Mass.) by electrophoretic separation of the unphosphorylated substrate and phosphorylated product Inhibition data were calculated by comparison of the no enzyme control reactions for 100% inhibition and vehicle-only reactions for 0% inhibition. The final concentration of reagents in the assay were 200 pM CK1ε or CK1δ, 50 uM ATP, 1.5 uM FL-AHA-KRRRAL-PSER-VASLPGL-OH, and 1.6% DMSO. Dose response curves were generated to determine the concentration required to inhibit 50% of the kinase activity (IC50). Compounds were dissolved at 10 mM in dimethylsulfoxide (DMSO) and evaluated at eleven concentrations. IC50 values were derived by non-linear regression analysis.

Assay: Fluorescence Polarization Assay: The enzyme and the substrate were each diluted with a 50 mM tris-hydrochloric acid buffer (pH 7.5) containing 12.5 mM KCl, 3.75 mM MgCl2, 25 μM iron sulfate, 5 mM ascorbic acid, and 2.5 mM DTT, whereas each test compound was diluted with dimethyl sulfoxide (DMSO).A test compound and the substrate solution were preliminarily added onto 384-well plates and reaction was initiated by adding a human PHD2 enzyme solution (40 ng/well). After 20-min incubation at 30° C., an EDTA-containing quench solution was added and the amount of the proline residues hydroxylated via binding to an added HIF-OH antibody solution was quantified by fluorescence polarization.

Target: Cannabinoid receptor 2 (SINGLE PROTEIN), Homo sapiens
UniProt: P34972
Assay: Binding Assay: The binding assays were performed by testing the ability of the new compounds to displace the radiolabeled synthetic non-selective cannabinoid agonist [3H]CP55940 (168 Ci/mmol; PerkinElmer) from the human CB1 (hCB1) or human CB2 (hCB2) receptors on membranes derived from stably transfected HEK-293 cells (PerkinElmer). Membranes were diluted in assay buffer (50 mM Tris-HCl, 1 mM EDTA, 1 mM MgCl2, 1 mg/ml BSA, pH=7.4). The amount of membrane was determined for each batch of membranes according to protein binding assay. The minimum amount of membrane that gave 50% specific binding was used for the binding assay. In most assays, binding was tested using 8 μg and 4 μg protein of hCB1 and hCB2 membranes, respectively. The tested compounds were dissolved in DMSO and diluted in assay buffer to a final concentration of 0.1% solvent. Total binding of [3H]CP55940 was evaluated with 1.5 nM to hCB1 and with 0.5 nM to hCB2, according to Kd affinity of [3H]CP55940 for the respective membranes. The ability of the tested compounds to displace [3H]CP55940 was evaluated first at a single concentration point of 100 nM for binding toward hCB2 or hCB1. In certain cases, the displacement was tested at compound concentrations ranging from 0.03 nM to 10 μM. Non-specific binding was measured by the addition of 1 μM of unlabelled CP55940 to the tubes. Binding assays were performed in triplicate in a total volume of 500 μl for 60 minutes at 30° C., in a shaking bath. Free and bound radioligands were separated by rapid filtration through GF/C filter plates (PerkinElmer) that had been presoaked with 0.1% Polyethylenimine (Sigma). Filters were shaken for 1 hour in 7 ml scintillation fluid (PerkinElmer) and radioactivity was determined by liquid scintillation counter (Wallac; PerkinElmer).
