Assay: Enzyme Assay: The affinity of compound binding to wild type and mutant human MET kinases is measured using Invitrogen's LanthaScreen Eu Kinase Binding technology. Briefly, GST-tagged recombinant human MET kinase domain from Signal Chem (see Table 8 below for concentration in assay) is incubated with 50 nM Alexa-Fluor® Tracer 236 (Invitrogen Cat No. PR9078A) and 2 nM Europium-anti-GST (Invitrogen Cat. No. A151 6) along with test compound in a buffer consisting of 25 mM HEPES, pH 7.4, 10 mM MgCl2, 0.01% Triton X-100, 1 mM DTT, and 2% DMSO. Compounds are typically prepared in a three-fold serial dilution in DMSO and added to the assay to give the appropriate final concentration. After a 60-minute incubation at 22° C., the reaction is measured using a PerkinElmer EnVision multimode plate reader via TR-FRET dual wavelength detection, and the percent of control (POC) calculated using a ratiometric emission factor. 100 POC is determined using no test compounds and 0 POC is determined using a concentration of control compound that completely inhibits the enzyme

Target: Sodium-dependent dopamine transporter (SINGLE PROTEIN), Homo sapiens
UniProt: Q01959
Assay: Functional Uptake Assay (hDAT): Inhibition of human dopamine reuptake transporter was assayed using the recombinant human dopamine transporter expressed in either CHO-K1 or HEK293 cells using a published method (Pristupa, Z. B. et al., Mol. Pharmacol. 45: 125-135, 1994). Either CHO-K1 or HEK293 cells expressing human recombinant dopamine 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 50 nM [3H]dopamine was then added for an additional timed incubation period (10 to 30 minutes). After washing the cells to remove [3H]dopamine not internalized, the cells were lysed, and the amount of tritium in the lysate was measured using a liquid scintillation counter to determine [3H]dopamine uptake. Non-specific binding of tritium was measured in a control reaction containing 10 uM nomifensine, and was subtracted from the counts for assays to correct for non-specific binding of tritium. Reduction of [3H]dopamine 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 nomifensine, for which the IC50 value of 11 nM was obtained in a typical experiment.

UniProt: Q9NR96
Assay: TLR7/8/9 Inhibition Reporter Assays: HEK-Blue-cells (Invivogen) overexpressing human TLR7, TLR8 or TLR9 receptors were used for screening inhibitors of these receptors using an inducible SEAP (secreted embryonic alkaline phosphatase) reporter gene under the control of the IFN-β minimal promoter fused to five NF-κc Band AP-1-binding sites. Briefly, cells are seeded into Greiner 384 well plates (15000 cells per well for TLR7, 20,000 for TLR8 and 25,000 for TLR9) and then treated with test compounds in DMSO to yield a final dose response concentration range of 0.05 nM-50 μM. After a 30 minute compound pre-treatment at room temperature, the cells are then stimulated with a TLR7 ligand (gardiquimod at a final concentration of 7.5 μM), TLR8 ligand (R848 at a final concentration of 15.9 μM) or TLR9 ligand (ODN2006 at final concentration of 5 nM) to activate NF-κB and AP-1 which induce the production of SEAP. After a 22 hour incubation at 37° C., 5% CO2, SEAP levels are determined with the addition of HEK-Bue Detection reagent (Invivogen), a cell culture medium that allows for detection of SEAP, according to manufacturer's specifications. The percent inhibition is determined as the % reduction in the HEK-Blue signal present in wells treated with agonist plus DMSO alone compared to wells treated with a known inhibitor.

Assay: Inhibition Assay: 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. The TLC plates are then dried, exposed to a phosphorimager screen (Storm, Amersham), and quantitated. For each compound, kinase activity is measured at 10-12 inhibitor concentrations representing two-fold dilutions from the highest concentration tested (typically, 200 μM). For compounds showing significant activity, IC50 determinations are repeated two to four times, and the reported value is the average of these independent measurements.

UniProt: Q9NYK1
Assay: TLR7/8/9 Inhibition Reporter Assays: HEK-Blue-cells (Invivogen) overexpressing human TLR7, TLR8 or TLR9 receptors were used for screening inhibitors of these receptors using an inducible SEAP (secreted embryonic alkaline phosphatase) reporter gene under the control of the IFN-β minimal promoter fused to five NF-κc Band AP-1-binding sites. Briefly, cells are seeded into Greiner 384 well plates (15000 cells per well for TLR7, 20,000 for TLR8 and 25,000 for TLR9) and then treated with test compounds in DMSO to yield a final dose response concentration range of 0.05 nM-50 μM. After a 30 minute compound pre-treatment at room temperature, the cells are then stimulated with a TLR7 ligand (gardiquimod at a final concentration of 7.5 μM), TLR8 ligand (R848 at a final concentration of 15.9 μM) or TLR9 ligand (ODN2006 at final concentration of 5 nM) to activate NF-κB and AP-1 which induce the production of SEAP. After a 22 hour incubation at 37° C., 5% CO2, SEAP levels are determined with the addition of HEK-Bue Detection reagent (Invivogen), a cell culture medium that allows for detection of SEAP, according to manufacturer's specifications. The percent inhibition is determined as the % reduction in the HEK-Blue signal present in wells treated with agonist plus DMSO alone compared to wells treated with a known inhibitor.

Compounds are typically prepared in a three-fold serial dilution in DMSO and added to the assay to give the appropriate final concentration. After a 60-minute incubation at 22° C., the reaction is measured using a PerkinElmer EnVision multimode plate reader via TR-FRET dual wavelength detection, and the percent of control (POC) calculated using a ratiometric emission factor. 100 POC is determined using no test compounds and 0 POC is determined using a concentration of control compound that completely inhibits the enzyme
