NOTES (numbers refer to sequence above)
1; HEK-293-SNCA-luc were cultured and suspended in phenol-red free DMEM (4.5 g/L glucose, 25 mM HEPES, cat #21063 (Thermo)).
3; Compounds were added to the assay plate in an 11-point intra plate dose response, 1:3 titration in DMSO with a final concentration range of xxx - yyy uM. Vehicle-only plates, with DMSO being pin-transferred to every well, were inserted at the beginning of screening runs to confirm expected assay performance. Activity was normalized to wells containing medium only (-100% activity, full inhibition) and SNCA-luc cells treated with DMSO vehicle control (0% activity), contained on the same plate as test samples.
10; Signals were analyzed, and dose-response curves were fit using the Hill equation. Compounds in curve classes -1.1, -1.2, -2.1, -2.2 in the SNCA-luc assay were considered active. Compounds were eliminated from further consideration if also active (curve class -1.1, -1.2, -1.3, -1.4, -2.1, -2.2, -2.3, -2.4) in the GF-AFC cytotoxicity assay.

Comment: Disclaimer:
Although all reasonable efforts have been made to ensure the accuracy and reliability of the data, caution should be exercised when interpreting the results as artifacts are possible from nonspecific effects such as assay signal interference. The curve fitting and activity calls presented here are based on the NCATS analysis methods.

Compound Ranking:
1. Compounds are first classified as having full titration curves, partial modulation, partial curve (weaker actives), single point activity (at highest concentration only), or inactive. For this assay, apparent inhibitors are ranked higher than compounds that showed apparent activation.
2. For all inactive compounds, with a ratio activity curve class of 4, PUBCHEM_ACTIVITY_SCORE is 0. For all active compounds, a score range was given for each curve class type given above. Active compounds have PUBCHEM_ACTIVITY_SCORE between 40 and 100. For a ratio activity curve class = -1.1, score = 80+abs((log_ac50+4.5)*inf_activity/20). For ratio.curve_class == -1.2 && abs(ratio.max_response) > 6*10, score = 60+abs((log_ac50+4.5)*inf_activity/20). For ratio.curve_class == -2.1 || ( ratio.curve_class==-2.2 && abs(ratio.max_response) > 6*10), score = 40+abs((log_ac50+4.5)*inf_activity/20). For ratio.curve_class == -1.2 || ratio.curve_class == -2.2, score = 20+abs((log_ac50+4.5)*inf_activity/20). Inconclusive compounds, with a donor curve class other than 4, have PUBCHEM_ACTIVITY_SCORE of 10. Inconclusive compounds have PUBCHEM_ACTIVITY_SCORE between 1 and 39.

Protocol: Tox21 Assay Protocol Summary:

Two ul of enzyme-substrate mix was dispensed into medium binding white/solid 1536-well plates (Greiner Bio-One North America Inc., Monroe, NC) using a BioRaptr Flying Reagent Dispenser (FRD, Beckman Coulter, Brea, CA). Compounds dissolved in DMSO and positive control (furafyllline) were transferred to the assay plates at 23 nl using a Pintool station (Wako, San Diego, CA). The assay plates were incubated at room temperature for 10 min. Then 2 ul of NADPH regeneration solution was added to each well of the assay plates using an FRD and incubated at room temperature for 1 h. The reaction was stopped by adding 4 ul of detection reagent using an FRD and after 20 min incubation at room temperature the luminescence signal was measured using a ViewLux plate reader (Perkin Elmer, Shelton, CT). Data were expressed as relative luminescence units.

External ID: IucA Pilot Assay Tocris Library

Protocol: A solution containing 55.6 mM HEPES pH 7.5, 0.11% Tween 20, 16.7 mM MgCl2, 55.6 mM hydroxylamine, 55.6 microM ATP, 55.6 microM citrate, and 0.28 U/mL IPP was dispensed (45 microL) into clear polystyrene microplates (Corning, Inc.) using a BioTek MicroFlo dispenser.

Next, 40 nL of test compounds (10 mM in DMSO, 8 microM final concentration) were transferred from deep-well blocks to the reaction solution using a stainless-steel pin tool operated by a robotic workstation (JANUS, PerkinElmer, Waltham, MA). The IucA-catalyzed reaction was initiated by adding 5 microL of 3 microM IucA in 25 mM HEPES, 75 mM NaCl, and 0.1 mM TCEP at pH 7.5.

The reactions were allowed to proceed for 30 min at room temperature before being quenched by dispensing (microFill, BioTek) 13 microL of MG developing solution, containing 1.0 mg/mL MG oxalate, 1.5% (w/v) ammonium molybdate, 0.15% (v/v) Tween 20, and 4.7 N sulfuric acid. After allowing the assay color to develop/stabilize for 30 min, the absorbance at 620 nm was measured (EnVision 2103 Multilabel Microplate Reader, PerkinElmer).

Average positive controls from 24 wells with no test compound and average negative controls from 8 wells with no enzyme were calculated. Dynamic range was calculated by difference between Avg Pos Control and Avg Neg Control. Percent inhibition was calculated by the ratio of (Avg. Pos. Ctrl - Sample OD) to Dynamic Range.

Protocol: The International Union of Basic and Clinical Pharmacology/British Pharmacological Society (IUPHAR/BPS) Guide to PHARMACOLOGY Database (GtoPdb) uses expert subcommittees to collate peer-reviewed information from the published literature regarding individual protein targets, and describes the pharmacology, genetics, function and anatomy of each target. Its pages provide a richly curated overview of the pharmacology of receptors, ion channels, enzymes and other target types, which can be found by following the external link to the GtoPdb website.

Comment: The data collected focuses on ligands at human receptors. Data are provided at rat or mouse orthologues where there are significant species differences, or where data are not yet available at the human target.

Information on individual experimental protocols can be found in the primary references listed for each ligand.

Affinity data are expressed as pKi [-log(Ki)], pKd [-log(Kd)], pIC50 [-log(IC50)], pEC50 [-log(EC50)], pKB [-log(KB)], pA2 or as a micromolar concentration range. In most cases the original concentration can be found in the primary reference.

Protocol:
Protocol:
1) Plate 10 uL BL2-NFkB-luc cells at 12.5K cells/well, using a Multidrop Combi reagent dispenser (1,250 cells/uL).
2) Add 25 nL compound or positive control, by pin transfer; IKK inhibitor VII will be used at 50 uM.
3) Incubate at 37 masculineC for 1 hour (allowing compounds to enter cells for action).
4) Add 5 uL 192 ng/mL tCD40L per well for a final concentration of 64 ng/ml using a Thermo Multidrop Combi.
5) Incubate at 37 masculineC for 4 hrs, then leave plate at RT for 30 minutes.
6) Add 15 uL SteadyGlo luciferase substrate (Promega) per well using a Thermo Multidrop Combi.
7) Incubate at RT for 5min, then read Luminescence using LJL Analyst HT plate reader.

Comment: PRESENCE OF CONTROLS: Neutral control wells (NC) and positive control wells (PC) were included on every plate.

EXPECTED OUTCOME: Active compounds result in decreasing readout signal.

NORMALIZATION:
The raw signals of the plate wells were normalized using the 'Neutral Controls Minus Inhibitors' method in Genedata Assay Analyzer (v10.0.2):
The median raw signal of the intraplate neutral control wells was set to a normalized activity value of 0.
The median raw signal of the intraplate positive control wells was set to a normalized activity value of -100.
Experimental wells values were scaled to this range.

PATTERN CORRECTION: No plate pattern correction algorithm from Genedata Condoseo (v.10.0.2) was applied.

PUBCHEM_ACTIVITY_SCORE:
This was set as equal to the mean of the normalized sample replicate activities, rounded to the nearest integer .
The minimum PUBCHEM_ACTIVITY_SCORE required for a compound to be called a hit (the activity threshold, or AT) was set at -50.

PERCENTAGE OF ACTIVE REPLICATES:
For each sample, the percentage of replicates (PCT_ACTIVE_REP) which had activity scores >= AT was determined.
The minimum percentage of replicates required for a compound to be called a hit (PAR_T) was set at 55.

PUBCHEM_ACTIVITY_OUTCOME:
Samples passing BOTH threshold criteria were assigned an outcome of 2 (active):
PUBCHEM_ACTIVITY_SCORE >= AT, and PCT_ACTIVE_REP >= PAR_T

Samples passing NEITHER threshold criteria were assigned an outcome of 1 (inactive):
PUBCHEM_ACTIVITY_SCORE < AT, and PCT_ACTIVE_REP < PAR_T

Samples passing AT only were assigned an outcome of 1 (inactive) :
PUBCHEM_ACTIVITY_SCORE >= AT, and PCT_ACTIVE_REP < PAR_T

Samples passing PAR_T only were assigned an outcome of 1 (inactive) :
PUBCHEM_ACTIVITY_SCORE < AT, and PCT_ACTIVE_REP >= PAR_T
