Target: Phosphatidylinositol 4,5-bisphosphate 3-kinase catalytic subunit beta isoform (SINGLE PROTEIN), Homo sapiens
UniProt: P42338
Assay: Inhibition Assays: Class I PI3-Ks can be either purchased (p110α/p85α, p110β/p85α, p110δ/p85α from Upstate, and p110γ from Sigma) or expressed as previously described (Knight et al., 2004). IC50 values are measured using either a standard TLC assay for lipid kinase activity (described below) or a high-throughput membrane capture assay. Kinase reactions are performed by preparing a reaction mixture containing kinase, inhibitor (2% DMSO final concentration), buffer (25 mM HEPES, pH 7.4, 10 mM MgCl2), and freshly sonicated phosphatidylinositol (100 μg/mL). Reactions are initiated by the addition of ATP containing 10 μCi of γ-32P-ATP to a final concentration of 10 or 100 μM and allowed to proceed for 5 minutes at room temperature. For TLC analysis, reactions are then terminated by the addition of 105 μL 1N HCl followed by 160 μL CHCl3:MeOH (1:1). The biphasic mixture is vortexed, briefly centrifuged, and the organic phase is transferred to a new tube using a gel loading pipette tip precoated with CHCl3. This extract is spotted on TLC plates and developed for 3-4 hours in a 65:35 solution of n-propanol:1M acetic acid.

Assay: Omnia Assay: Briefly, 10x stocks of EGFR-WT (PV3872) from Invitrogen and EGFR-T790M/L858R (40350) from BPS Bioscience, San Diego, Calif., 1.13×ATP (AS001A) and appropriate Tyr-Sox conjugated peptide substrates (KCZ1001) were prepared in 1× kinase reaction buffer consisting of 20 mM Tris, pH 7.5, 5 mM MgCl2, 1 mM EGTA, 5 mM β-glycerophosphate, 5% glycerol (10× stock, KB002A) and 0.2 mM DTT (DS001A). 5 μL of each enzyme were pre-incubated in a Corning (#3574) 384-well, white, non-binding surface microtiter plate (Corning, N.Y.) for 30 min. at 27° C. with a 0.5 μL volume of 50% DMSO and serially diluted compounds prepared in 50% DMSO. Kinase reactions were started with the addition of 45 μL of the ATP/Tyr-Sox peptide substrate mix and monitored every 30-90 seconds for 60 minutes at λex360/λem485 in a Synergy4 plate reader from BioTek (Winooski, Vt.). At the conclusion of each assay, progress curves from each well were examined for linear reaction kinetics and fit statistics (R2, 95% confidence interval, absolute sum of squares). Initial velocity (0 minutes to 30 minutes) from each reaction was determined from the slope of a plot of relative fluorescence units vs time (minutes) and then plotted against inhibitor concentration to estimate IC50 from log[Inhibitor] vs Response, Variable Slope model in GraphPad Prism from GraphPad Software (San Diego, Calif.).

Target: Somatostatin receptor type 5 (SINGLE PROTEIN), Homo sapiens
UniProt: P35346
Assay: Radioligand Binding Assay: Receptor binding assays refer to a technique in which labeled receptor ligands are used to detect binding to a receptor. In competition experiments test compounds, which are not labeled, compete with the binding side of a labeled ligand. The displacement of the labeled ligand by the test compound leads to a decreased signal.Procedure:For the binding experiments 200 μL of membrane homogenate from one of the following protein amounts is used: hSSTR1 (40 μg/well); hSSTR2 (25 μg/well); hSSTR3 (1.5 μg/well); hSSTR4 (0.5 μg/well); hSSTR5 (25 μg/well). The homogenate is incubated with 0.05 nM of radioligand ([3-125I-Tyr]-Somatostatin-(1-14)) in addition to increasing concentrations of a test compound or vehicle (100% binding) in a total volume of 250 μL using a Hepes buffer (10 mM, EDTA 1 mM, MgCl2 5 mM, pH7.6, BSA 0.5%, Bacitracin 0.003%, DMSO 1%) for 180 min at room temperature. The incubation is terminated by filtration with ice cold NaCl 0.9% through polyethyleneimine treated (0.3%) GF/B glass fiber filters using a cell harvester. The protein-bound radioactivity is measured in a suitable reader. The non-specific binding is defined as radioactivity bound in the presence of 1 μM Somatostatin-14 during the incubation period.

Assay: Functional Uptake Assay (rSERT): Quantification of 5-HT uptake was performed using synaptosomes isolated in a 0.32M sucrose buffer from a male Wistar rat cortex. The uptake of radiolabelled 5-HT by synaptosomes (100 ug of proteins/point) was allowed by incubating them in a well for 15 min at 37° C. in presence of test compounds and [3H]5-hydroxytryptamine (serotonin; 0.1 uCi/point). Synaptosomes and [3H]serotonin were prepared in a Krebs buffer pH 7.4 containing 25 mM NaHCO3, 11 mM glucose and 50 uM ascorbic acid. This incubation buffer was oxygenated during 5 minutes before incubation. Basal control was incubated for 15 minutes at 4° C. in order to avoid any uptake. Following this incubation the uptake was stopped by filtration through a unifilter 96-wells GFB Packard plate washed with Krebs buffer containing 25 mM NaHCO3 in order to eliminate the free [3H]serotonin. The radioactivity associated to the synaptosomes retained on the unifilter corresponding to the uptake was then measured with a microplate scintillation counter (Topcount, Packard) using a scintillation fluid.

Assay: Functional Uptake Assay (rDAT): Quantification of dopamine uptake was performed using synaptosomes isolated in a 0.32 M sucrose buffer from a male Wistar rat striatum. The uptake of radiolabelled dopamine by synaptosomes (20 ug of proteins/point) was allowed by incubating them for 15 minutes at 37° C. in the presence of test compounds and [3H]-dopamine (0.1 uCi/point). The experiment was performed in a deep well. Synaptosomes and [3H]-dopamine were prepared in a Krebs buffer pH 7.4 containing 25 mM NaHCO3, 11 mM glucose and 50 uM ascorbic acid. This incubation buffer was oxygenated for 5 minutes before incubation. Basal control was incubated for 15 minutes at 4° C. in order to avoid any uptake. Following this incubation, the uptake was stopped by filtration through a unifilter 96-wells GFB Packard plate washed with Krebs buffer containing 25 mM NaHCO3 in order to eliminate free [3H]-dopamine. The radioactivity associated to the synaptosomes retained onto the unifilter corresponding to the uptake was then measured with a microplate scintillation counter (Topcount, Packard) using a scintillation fluid.

Assay: Inhibition Assays: Class I PI3-Ks can be either purchased (p110α/p85α, p110β/p85α, p110δ/p85α from Upstate, and p110γ from Sigma) or expressed as previously described (Knight et al., 2004). IC50 values are measured using either a standard TLC assay for lipid kinase activity (described below) or a high-throughput membrane capture assay. Kinase reactions are performed by preparing a reaction mixture containing kinase, inhibitor (2% DMSO final concentration), buffer (25 mM HEPES, pH 7.4, 10 mM MgCl2), and freshly sonicated phosphatidylinositol (100 μg/mL). Reactions are initiated by the addition of ATP containing 10 μCi of γ-32P-ATP to a final concentration of 10 or 100 μM and allowed to proceed for 5 minutes at room temperature. For TLC analysis, reactions are then terminated by the addition of 105 μL 1N HCl followed by 160 μL CHCl3:MeOH (1:1). The biphasic mixture is vortexed, briefly centrifuged, and the organic phase is transferred to a new tube using a gel loading pipette tip precoated with CHCl3. This extract is spotted on TLC plates and developed for 3-4 hours in a 65:35 solution of n-propanol:1M acetic acid.

Assay: Functional Uptake Assay (hSERT): Inhibition of human serotonin reuptake transporter was assayed using the recombinant human serotonin transporter expressed in HEK-293 cells. HEK-293 cells expressing human serotonin transporter were plated before the assay. Test compound and/or vehicle was preincubated with cells in modified HEPES buffer pH 7.1 or pH 7.4 for 20 minutes at 18 to 25° C. and 65 nM [3H]serotonin was then added for an additional timed incubation period (ten to thirty minutes). Cells with internalized [3H]serotonin were washed and the amount of tritium taken into cells is counted using a liquid scintillation counter to determine [3H]serotonin uptake. Non-specific binding of tritium was measured in a control reaction containing 10 uM fluoxetine, and was subtracted from the counts for assays to correct for non-specific binding of tritium. Reduction of [3H]serotonin uptake by 50 percent or more (50%) relative to an uninhibited control reaction indicates significant inhibitory activity. Compounds were screened at 10, 1, 0.1, 0.01 and 0.001 uM. The reference compound for the assay was fluoxetine, for which the IC50 value of 7.1 nM was obtained in a typical experiment.

Cells pellets (1×109 cells/pellet) were suspended in buffer containing 20 mM HEPES (4-(2-hydroxyethyl)-1-piperazineethanesulfonic acid), pH 7.5, 50 mM NaCl, 2 mM EDTA (Ethylenediaminetetraacetic acid) and Protease Inhibitor cocktail (Roche), and disrupted on ice using the Polytron homogenizer. The homogenate was centrifuged at 20,000 rpm (48,000 g) and the supernatant was discarded. The membrane pellets were resuspended in buffer containing 50 mM HEPES, pH 7.5, 100 mM NaCl, 1 mM MgCl2, 2 mM EDTA and stored in aliquots at −80° C. after protein concentration determination. Membranes (2 μg/well) and 0.03 nM final concentration of 33P-S1P ligand (1 mCi/ml, Perkin elmer or American Radiolabeled Chemicals) diluted in assay buffer (50 mM HEPES, pH7.4, 5 mM MgCl2, 1 mM CaCl2, 0.5% fatty acid free BSA (bovine serum albumin), 1 mM NaF) were added to the compound plates (384 Falcon v-bottom plate (0.5 μl/well in a 11 point, 3-fold dilution). Binding was performed for 45 minutes at room temperature, terminated by collecting the membranes onto 384-well Millipore FB filter plates, and radioactivity was measured by TOPCOUNT®. The competition data of the test compounds over a range of concentrations was plotted as percentage inhibition of radioligand specific binding. The IC50 is defined as the concentration of competing ligand needed to reduce specific binding by 50%.
