Compound (SMILES): CCOc1cc([C@@H]2NC(=O)NC(c3cccnc3)=C2c2ccsc2)cc([N+](=O)[O-])c1O
InChIKey: OOLWDJTWVWHETJ-IBGZPJMESA-N
Target: Alcohol dehydrogenase class-3 (SINGLE PROTEIN), Homo sapiens
UniProt: P11766
Assay: Binding Assay: Receptor binding assays were performed using crude membranes prepared from CHO cells expressing human NK3 receptor. Osanetant (SR142801), a non-peptide NK3 antagonist, was used as a ligand, and SB222200 was used as a positive control reference compound. The assay was performed with cell membrane homogenates (24 ug protein) incubated for 120 min at 22 C. with 0.4 nM [3H]SR142801 in the absence or presence of the test compound in a buffer containing 20 mM Hepes/NaOH (pH 7.4), 120 mM NaCl, 1 mM MnCl2, 0.01% bacitracin, 0.002% aprotinin and 0.1% BSA. Following incubation, the samples were filtered rapidly under vacuum through glass fiber filters (GF/B, Packard) that had been presoaked with 0.3% PEI. The filters were rinsed several times with ice-cold 50 mM Tris/HCl using a 96-sample cell harvester (Unifilter, Packard), dried, and counted for radioactivity in a scintillation counter (Topcount, Packard) using a scintillation cocktail (Microscint 0, Packard).

Assay: Enzyme Inhibition Assay: DPP4 activity was measured using a continuous fluorometric assay. The substrate, Gly-Pro-AMC, was cleaved by DPP4 to release the fluorescent AMC group. The reaction was monitored at the excitation wavelength of 360 nm and emission wavelength of 460 nm in a black 384-well plate using a PHERAstar Plus plate reader (BMG Labtech., Inc.) set at 37 C. The 30 ul assay solution contained 20 uM recombinant human DPP4 and 50 uM Gly-Pro-AMC substrate in assay buffer (100 mM HEPES, 100 mM NaCl, 0.1 mg/ml BSA, pH 7.5). The reaction was linear for at least 30 min (initial velocity) after addition of the substrate (no inhibitor control). All materials and reagents were pre-incubated at 37 C. prior to start of the experiment. Test compounds were serially diluted (3-fold) in 100% DMSO to avoid solubility issues; working solutions in 3% DMSO were prepared using assay buffer. 101 each of enzyme and compound solutions were mixed and pre-incubated at 37 C. for 30 minutes.

In this homogeneous test the amount of ATP remaining after the kinase reaction is quantified by a luciferin-luciferase reaction using luminescence. The luminescence signal obtained correlates with the amount of ATP still present and thus correlates inversely with the activity of the protein kinase.MethodThe test compounds were dissolved in 100% DMSO at a concentration of 10 mM and diluted in DMSO to a concentration of 1 mM.

Assay: Kinase Assay: Recombinant human Syk (amino acids 342-635) was expressed as a fusion protein with an N-terminal GST tag, affinity-purified and deep-frozen at a concentration of approx. 50-100 uM in test buffer (25 mM HEPES pH7.5; 25 mM MgCl2; 5 mM MnCl2; 50 mM KCl; either 0.2% BSA or 0.2% HSA; 0.01% CHAPS; 100 uM Na3VO4; 0.5 mM DTT) and 10% glycerol at -80 C. until use.The catalytic activity of the GST-Syk kinase fusion protein was determined using the Kinase Glo Luminescence Kinase test (Promega; V6712). In this homogeneous test the amount of ATP remaining after the kinase reaction is quantified by a luciferin-luciferase reaction using luminescence. The luminescence signal obtained correlates with the amount of ATP still present and thus correlates inversely with the activity of the protein kinase.MethodThe test compounds were dissolved in 100% DMSO at a concentration of 10 mM and diluted in DMSO to a concentration of 1 mM.

Assay: Inhibition Assay: MDCK cells stably transfected with rat PGT (Endo et al., 2002) were seeded at 15-20% confluence on 24-well plates. The day on which the cells were seeded was considered day 1. PGE2 uptake experiments were conducted on day 4. All of the PGE2 uptake experiments were conducted at room temperature. On day 4, cells were washed twice with Waymouth buffer (135 mM NaCl, 13 mM H-Hepes, 13 mM Na-Hepes, 2.5 mM CaCl2, 1.2 mM MgCl2, 0.8 mM MgSO4, 5 mM KCl, and 28 mM D-glucose). Then 200 μL of Waymouth buffer containing [3H]PGE2 (purchased from Perkin Elmer) was added to each well. At the designed time, the uptake of [3H]PGE2 was stopped by aspiration of uptake buffer; this was followed by immediate washing twice with 500 μL of chilled Waymouth buffer. Cells were then lysed with 100 μL lysis buffer containing 0.25% SDS and 0.05 N NaOH. 1.5 mL of scintillation solution was added to each well, and intracellular [3H]PGE2 was counted by MicroBeta Counter.

Target: Solute carrier organic anion transporter family member 2A1 (SINGLE PROTEIN), Rattus norvegicus
UniProt: Q00910
Assay: Inhibition Assay: MDCK cells stably transfected with rat PGT (Endo et al., 2002) were seeded at 15-20% confluence on 24-well plates. The day on which the cells were seeded was considered day 1. PGE2 uptake experiments were conducted on day 4. All of the PGE2 uptake experiments were conducted at room temperature. On day 4, cells were washed twice with Waymouth buffer (135 mM NaCl, 13 mM H-Hepes, 13 mM Na-Hepes, 2.5 mM CaCl2, 1.2 mM MgCl2, 0.8 mM MgSO4, 5 mM KCl, and 28 mM D-glucose). Then 200 μL of Waymouth buffer containing [3H]PGE2 (purchased from Perkin Elmer) was added to each well. At the designed time, the uptake of [3H]PGE2 was stopped by aspiration of uptake buffer; this was followed by immediate washing twice with 500 μL of chilled Waymouth buffer. Cells were then lysed with 100 μL lysis buffer containing 0.25% SDS and 0.05 N NaOH. 1.5 mL of scintillation solution was added to each well, and intracellular [3H]PGE2 was counted by MicroBeta Counter.
