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.

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.

External ID: HMS1625

Protocol: The fix-reporter plasmid was conjugated into this strain which the stably integrates into the chromosome using the mini-Tn7 system (PMID: 15908923). This plasmid consists of the fixK promoter, which is a target of the fixLJ pathway driving expression of GFP.
The day before screen an overnight culture of B. multivorans strain VC7102, with fix reporter, is set up in tryptic soy broth (TSB) at 37 degrees C with shaking. The day of the screen the overnight culture is diluted 1:100 in fresh tryptic soy broth.
The day of the screen, 30 microL of tryptic soy broth (TSB) is pipetted into columns 1-22 of a 384-well plate (Corning 3764) using the Combi multidrop dispenser. To column 24, 30 microL of TSB containing 78 microM of Benserazide TSB is added for a positive control. To column 23, 30 microL of TSB containing with DMSO (0.078% v/v in TSB) is added for a negative control. 300 nL of each compound are pin-transferred to each plate. For every compound plate 2 replicate assay plates are set up. 30 microL of the 1:100 diluted-B. multivorans strain VC7102 is added to each well using the Combi. Initial OD600 and GFP are measured using the PerkinElmer EnVision. Plates are stacked 5 high, covered with lids and incubated at 37 degrees C overnight (~18 h).
The following day, assay plates are read using a PerkinElmer EnVision (600 nm filter and GFP).
Positive control: Benserazide 39 microM in column 24 (No positive control was used for plates 2089 & 2090; Plates 2091-2093: columns 1 & 24)
Negative control: DMSO 300 nL/well in column 23 (For plates 2089 & 2090 negative controls were located in columns 2 & 24; plates 2091-2093: columns 2 & 23)

Comment: Analysis method:
For each compound well, the initial GFP value was subtracted from overnight GFP value to calculate the deltaGFP. The mean and standard deviation of the negative control wells deltaGFP (column 23) on both replicate plates was calculated. Wells with replicate average deltaGFP at least 3 standard deviations above the plate negative control deltaGFP average were scored as potential positives.

To determine activity scores, Z-scores were calculated for each replicate separately based on the replicate negative control deltaGFP plate average and standard deviation. The replicate average deltaGFP Z-scores were used for activity scores, with activity score of 100 set to Z-score = 4 and activity score = 0 (no activity) set to Z-score = 0. Z-scores > 4 were considered activity score = 100, and Z-scores < 0 were considered activity score = 0.

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.

NOTES (numbers refer to Sequence numbers above)
1. The cell-based screening methods employed in this study were like those previously published [1]. Briefly, the corresponding myeloma cell lines were screened in 1,536-well plates with 500 cells, 5-uL per well for inhibition of cell viability (assessed by measuring ATP levels with CellTiterGlo).
2. NCATS MIPE 4.0 library of approved and investigational drugs were added using the Kalypsis pin tool. Wells treated with DMSO only for 100% viability and media only for 0% viability were used as controls.
3. The assay plates were covered and incubated for 48 hours in a 37C, 5% CO2 incubator with controlled humidity.
4. After 48 hours, CellTilter-GloTM luminescent substrate mix (Promega) reagent was added to the assay plate and plates we incubated for 5 min at room temperature.
5. Signal was measured as median relative luminescence units on a ViewLux (PerkinElmer) multiplate reader.

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 cytotoxic compounds are ranked higher than compounds that showed no activity.
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.
