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.

NOTES (numbers refer to sequence above)
1; SH-SY5Y human neuroblastoma cells stably expressing GLuc-SERCaMP (SH-SY5Y-GLuc-ASARTDL) cells were seeded in 1,536 well white tissue culture treated plates (Corning, Cat# 7464) in DMEM-high glucose-sodium pyruvate (ThermoFisher Scientific, Cat #10569) supplemented with 10% bovine growth serum (Hyclone), 10 U/ml penicillin (Gibco), 10 ug/ml streptomycin (Gibco), and 20 mM HEPES.
2; Assay plates were incubated for 5 hour at 37C in a humidified incubator containing 5% CO2.
3; qHTS libraries (23 nl, final concentrations of 1.53 uM, 7.67 uM, 38.3 uM) or controls (neutral control: DMSO, positive control: dantrolene) were added using a Kalypsis pin-tool Robotic System equipped with 1536 pinheads.
4; Cells were then incubated for 16 hours at 37C, 5% CO2.
5; Thapsigargin was added at 100 nM to deplete ER calcium stores.
6; Cells were incubated for 4 hour (37oC, 5% CO2)
7; Gaussia luciferase in the medium was measured by adding 1 ul of 0.5x coelenterazine (final concentration 0.07x) prepared in Gaussia Luciferase Glow Assay Buffer (Pierce), without addition of the Cell Lysis Buffer Reagent.
8; Luminescence was measured using a ViewLux high-432 throughput CCD imaging system (Perkin Elmer) equipped with clear filters. Compounds exhibiting inhibitory activity (defined as curve class -1.1, -1.2, -1.3, -1.4, -2.1, -2.2, -2.3, -2.4, -3) were identified by normalizing plate-wise to corresponding intra-plate controls (neutral control = Tg only; positive control (100% inhibition) = DMSO vehicle) with percent activity derived using in-house software (https://tripod.nih.gov/curvefit). The same controls were also used for the calculation of the Z' factor, a measure of assay quality control, as previously described (Zhang et al., 1999). For the initial validation of activity in the SERCaMP assays, hits from the primary screen were assayed again at 11-concentrations (1.3 nM - 76.6 uM). SH-SY5Y-GLuc-SERCaMP cells were assayed for ER Ca2+ depletion as outlined above.

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.

Protocol: NCGC Assay Protocol Summary:

The assay buffer, prepared fresh at the day of the assay, contains 20mM Tris-HCl pH 8.0, 2mM CaCl2, 2mM beta-Mercaptoethanol, 0.05% CHAPS. 3ul of 20nM (10nM final) USP2 core, which is stored on ice, is dispensed into a medium-binding black solid Kalypsys 1,536 well plate using the Kalypsys dispenser. The assay plate is then pinned with 23nL compound with the Kalypsys pintool in columns 5-48. The controls are pinned as follows: column 1 two-fold dilutions of 2M NEM in duplicate; column 2 2M NEM (final concentration 38.2mM); column 3&4 DMSO. The assay plate is incubated at RT for 30min. Subsequently, 1.5uL of 100nM (25nM final) Ub-CHOP2 and 1.5uL of 100nM (25nM final) Reporter Substrate (both stored on ice and protected from light) were dispensed into the plate using the Kalypsys dispenser. Plates were read after 60min RT incubation on a ViewLux (Perkin Elmer) plate reader using the following wavelengths Ex 485nm /Em 531nm.

Data were normalized to the to AC100 inhibition (NEM). Concentration-response curves were fitted to the normalized data and the concentration-response curves were then classified based on curve quality (r2), response magnitude and degree of measured activity. The time zero reading was used to flag fluorescence artifacts.

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: Briefly, three uL of reagents (100 nM EPAC1, 250 nM RAP1B-BODIPY-GDP, 50 uM GDP) were dispensed into a 1536-well Greiner black solid-bottom medium binding assay plate. Controls and test compounds (23 nL) were transferred to the plate via a Kalypsys pin tool equipped with a 1536-pin array. The plates were centrifuged at 1,000 rpm for 15 seconds followed by 5 minute incubation at room temperature. The assay plates were read at 5 minute intervals for 30 minutes in the ViewLux plate reader using 480nm excitation and 540nm emission filters. The results were normalized to the agonist positive control of 6.5 mM cAMP.

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.
