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.

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).

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.

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.
