Assay: Surface Plasmon Resonance (SPR)Assay: The interactions between compounds and ABAD were performed using the dual flow cell BIACORE 3000 instrument. Surface Plasmon Resonance (SPR) studies were performed on a BIACORE 3000 at 25° C. SPR binding experiments with ABAD were performed in phosphate-buffered saline (PBS, pH 7.4, 0.005% surfactant P20) as the running and the sample buffer. The surface of the sensor chip was first activated with mixtures of N-hydroxysuccinimide (NHS, 115 mg/ml) and N-(3-dimethyl-aminopropyl)-N'-ethyl-carbodiimide-hydrochloride (EDC, 750 mg/ml) for 7 minutes. ABAD was dissolved in PBS buffer (pH 5.0) at a concentration of 10 μg/ml. The protein was immobilized directly and covalently on the hydrophilic carboxymethylated dextran matrix of the CM5 sensor chip (BIACORE) by using the standard primary amine coupling reaction on a CM5 sensor chip according to standard procedures. After the immobilization of the protein, excess activated carboxylic acid groups were quenched with ethanolamine (1 M, pH 8.5). Special care was taken during injection of samples because of carryover effects. Special washing routines were used to clean the system before injection of new samples. In addition, predipping of needles was performed. The sample flow was 40 μl/minute in experiments performed for the determination of the kinetic and equilibrium constants. Regeneration of the surfaces between subsequent binding experiments was achieved by washing the surface extensively (>>1 hour) with buffer solution.

Assay: Mutant IDH1 Biochemical Assay: LC-MS Detection of 2-HG: Mutant IDH1 R132H catalytic activity was monitored using the quantitative liquid chromatography/mass spectrometry (LC-MS) detection of 2-HG, a product of the NADPH-dependent alpha-KG reduction reaction.More specifically, the biochemical reactions were performed at room temperature in 384-well Greiner flat-bottom plates (Costar, Cat. No. 781201) using a final reaction volume of 30 μL and the following assay buffer conditions: 50 mM HEPES pH 7.4, 10 mM MgCl2, 50 mM KCl, 1 mM DTT, 0.02% BSA, 5 uM NADPH and 100 uM alpha-KG.The final reaction mixture contained 3.3% DMSO and inhibitors with concentrations ranging 0.02-50 μM. The IDH1 enzyme was used at a final concentration of 0.25 nM. Following 45 minutes incubation, the reaction mixtures were quenched by the addition of 10 μL of 16% formic acid containing 800 nM of 5-carbon labeled 13C-2-HG). The protein was then precipitated by the addition of 2.5 volumes of acetonitrile followed by centrifugation (3000×g, 20 minutes). 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).

Target: Kappa-type opioid receptor (SINGLE PROTEIN), Homo sapiens
UniProt: P41145
Assay: Functional Assay: Functional [35S]GTPgammaS binding assays were conducted as follows. kippa opioid receptor membrane solution was prepared by sequentially adding final concentrations of 0.026 ug/ul kippa membrane protein (in-house), 10 ug/mL saponin, 3 uM GDP and 0.20 nM [35S]GTPgammaS to binding buffer (100 mM NaCl, 10 mM MgCl2, 20 mM HEPES, pH 7.4) on ice. The prepared membrane solution (190 ul/well) was transferred to 96-shallow well polypropylene plates containing 10 ul of 20x concentrated stock solutions of agonist prepared in DMSO. Plates were incubated for 30 min at a temperature of about 25° C. with shaking. 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 2001 ice-cold binding buffer (10 mM NaH2PO4, 10 mM Na2HPO4, pH 7.4). Filter plates were subsequently dried at 50° C. for 2-3 hours.

Target: Delta-type opioid receptor (SINGLE PROTEIN), Homo sapiens
UniProt: P41143
Assay: Beta-Opioid Binding Assay: Radioligand dose-displacement assays used 0.2 nM [3H]-Naltrindole (NEN; 33.0 Ci/mmole) with 10-20 ug membrane protein (recombinant delta opioid receptor expressend in CHO-K1 cells; Perkin Elmer) in a final volume of 500 uL binding buffer (5 mM MgCl2, 5% DMSO, 50 mM Trizma base, pH 7.4). Non-specific binding was determined in the presence of 25 uM unlabeled naloxone. All reactions were performed in 96-deep well polypropylene plates for 1 h at a temperature of about 25 °C. Binding reactions were determined by rapid filtration onto 96-well Unifilter GF/C filter plates (Packard) presoaked in 0.5% polyethylenimine (Sigma). Harvesting was performed using a 96-well tissue harvester (Packard) followed by five filtration washes with 500 uL ice-cold binding buffer. Filter plates were subsequently dried at 50 °C. for 1-2 hours. Fifty uL/well scintillation cocktail (MicroScint20, Packard) was added.

UniProt: Q2L8D9
Assay: Assay of ABAD Enzymatic Activity: The assay for the inhibition of reduction of S-acetoacetyl-CoA (SAAC) by ABAD was carried out with ABAD (418 ng/ml), SAAC (172 μM), NADH (102 μM), and different concentrations of inhibitors (from 0 to 1000 μM) in 93 mM potassium phosphate buffer (pH 7.3). Before the assay, all the assay components except SAAC were pre-incubated for 5 minutes, and the reaction started with the addition of SAAC into the reaction mix. The reaction was carried out for a total 6 minutes at room temperature under steady-state conditions, and the decrease of NADH absorbance at 340 nm was determined every 10 seconds. Kinetic data were analyzed by PRISM (Scitech, San Diego, Calif.) to determine IC50 values and Ki. One unit of enzyme activity was defined as that which converted 1.0 μmol of substrate to product per minute.
