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: ZIK159

Protocol: Assay Protocol Summary:

The medium for SNB-19 cells is composed of RPMI 1640 (ATCC, Cat.# 30-2001), 10% fetal bovine serum (FBS) (GE healthcare Life Sciences, Cat.# SH30071.03), and 1% Pen/Strep (Gibco, Cat.# 15140-122). A Caspase-Glo 3/7 assay kit (catalog number G8092; Promega, Madison, WI) was used to detect caspase-3 activity induced by Zika virus infection in human cells. The reagent mixture was reconstituted as described in the protocol from the manufacturer. Polystyrene tissue culture treated and PDL coated white plates were obtained from Greiner Bio-One (Monroe, NC). Cells were seeded in 384- or 1536-well assay plates and cultured at 37 C with 5% CO2 for 16 to 20 hours. The typical cell seeding density in the 1536-well plate assay is 250 cells/well in 3ul medium for SNB-19 cells in tissue culture treated plates. Compounds were added to cells and incubated for one hour before addition of ZIKV solution to cells (2 FFU/cell). After incubation at 37 C with 5% CO2 for 6 hours, the reagent mixture of Caspase-Glo 3/7 assay kit was added to each well, followed by incubation at room temperature for 30 minutes. The luminescence intensity of the assay plates was measured using a ViewLux plate reader (PerkinElmer). Data were normalized by using the cell-containing wells without ZIKV as a negative control (0% induction of caspase 3/7 activity) and wells containing ZIKV infected cells (Caspase-3 activity induced) as a positive control (100% induction of caspase 3 activity). The percentage inhibitions of the increased Caspase-3 activity by small molecule inhibitors were then calculated.

Comment: 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. See data field "Curve Description". For this assay, apparent inhibitors are ranked higher than compounds that showed apparent activation.
2. For all inactive compounds, 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. Inconclusive compounds have PUBCHEM_ACTIVITY_SCORE between 1 and 39. Fit_LogAC50 was used for determining relative score and was scaled to each curve class' score range.

External ID: CF Folding

Protocol: A high throughput 384-well microplate based fluorescence assay was developed using HeLa cells engineered to express F508del-CFTR. Cells were maintained in cell culture media (High Glucose DMEM (Gibco) supplemented w/ 10% FBS (Gibco)). For the assay, cells were trypsinized (0.25% Trypsin-EDTA solution (Gibco)) and resuspended in assay media (cell culture media + 1% Pen/Strep (Gibco)) at a density of 320,000 cells per ml. Cells were dispensed to the assay plates (Corning 3712) in 25 ul using a Wellmate (Matrix/Thermo). Plates were incubated overnight at 37C, 5% CO2 and high humidity. The next day, compounds were prepared by making a dilution in assay media to a concentration of either 150 uM or 60 ug/ml (6x) depending on the library being screened. Then 5 ul of the diluted compound was transferred to the assay plate containing the cells. Assay plates were incubated for 24 hours 37C, 5% CO2 and high humidity. Following incubation with the compounds, relative cell number was determined by adding 3 ul of alamarBlue (TREK Diagnostics) and incubating the plates at 37C, 5% CO2 and high humidity, until cell control values reached ~4 million, as measured with a fluorescent intensity protocol on an Envision multimode plate reader (Perkin Elmer) (excitation 535 nm, emission 595 nm wavelengths) . Following the alamarBlue read, the media was removed and the cells were fixed with the addition of 13 ul of 4% paraformaldehyde in PBS (pH 7.4) and incubated for 10 minutes at room temperature. Plates were washed twice with PBS to remove the fixative. Cells were permeabilized with the addition of blocking solution (PBS, 0. 1% Triton X-100, 10 mg/ml BSA) and incubated at room temperature for 30 minutes. The blocking solution was removed and the primary antibody mixture was added in 13ul (Antibodies UNC570 and UNC596; CFF Therapeutics, Inc., Bedford, MA) at a 1/5000 dilution of each antibody in blocking solution. Plates were then incubated over night at 4oC. Primary antibody was removed by washing three times with 50 ul of wash solution (PBS, 0.1% Triton X-100) with at least 5 minutes between wash cycles. Secondary antibody (Alexa 488 anti-mouse IgG Invitrogen) was then added in a volume of 13 ul (1/1000 dilution in blocking solution) and incubated for two hours at room temperature in the dark. To remove excess secondary antibody, plates were washed three times with 50 ul of wash solution and one time with 50 ul of PBS. Plates were read from the bottom using a fluorescent intensity protocol on an Envision multimode plate reader (485 nm excitation and 535 nm emission).
To minimize the disruption of the cell monolayer during the numerous washes, the following process was used. The removal of media or other reagents for the wells of the microtiter plate was done using a Biomek FX (Beckman, Fullerton CA) with a 384 tip multichannel head. Aspiration was done at a slow rate following the liquid level with the tip positioned in the top right corner of the well. All solution additions, starting with the fixative, were done with a Matrix Wellmate. Again to avoid disturbing the cell monolayer, the plate offset was adjusted so that the liquid dispensed to the left wall of the well rather than directly on the cell monolayer.
For the screen, approximately ten thousand compounds from a mix of FDA and diverse libraries (MicroSource Pharmacon-1600 (FDA), Enzo (FDA), Selleck (FDA) and Enamine) were tested at a final concentration 25 uM (Enzo, Selleck & MS Pharmakon) or 10 ug/ml (Enamine 30K diversity set). The proteasome inhibitor ALLN was used as the positive control (50 uM) and 100 uM Hyamine was used as a viability control on all microtiter plates. All wells including the cell controls contained 0.5% DMSO. In-plate controls were used to normalize the data and results were reported as fold increase above the cell control and normalized to relative cell number derived from the alamarBlue data.
Ninety six compounds identified in the single dose screen were evaluated further in dose response. Compound high dose was twice the screening concentration and a ten point series of two fold dilutions were done for each compound. DMSO concentration was 1% for in all wells. Compounds were evaluated in both the immunostain assay and in the cell viability assay.

Data Analysis: Thirty two control wells containing cells only, 24 wells containing Hyamine and 8 wells containing ALLN were included on each assay plate and used to calculate Z' value for each plate and to normalize the data on a per plate basis. Data were analyzed using the IDBS Activity Base software. Results were expressed as Fold Increase (FI) for the immunostain assay and cell viability (V) for the alamarBlue assay. Final data was reported as Normalized fold increase (NFI). Data was analyzed as follows FI=DataValue/Median cell control, V= (DataValue-median Hyamine control)/(median cell control -median Hyamine control) and NFI=FI/V.

For the immunostain dose response assay, IC50 values were calculated for active compounds by plotting the FI for each concentration, and using a 4 parameter Levenburg-Marquardt algorithm with the minimum limit set at 0. Similarly, EC50 values were calculated for the cell viability dose response assay, plotting the % Viability at each concentration and also using a 4 parameter Levenburg-Marquardt algorithm with the minimum limit set at 0 and the maximum limit set at 100.

Outcome- From the primary screen, compounds selected as Active were those that met one of the following two criteria: (1) Fold Induction >/= 1.5, Cell Viability >/= 50% and the ratio of Fold Induction to Cell Viability >/= 1.5; or (2) Fold Induction >/= 1, Cell Viability >/= 50% and the ratio of Fold Induction to Cell Viability >/=1.75. While 101 compounds met this criteria, 96 were ultimately selected for confirmatory screening. For the dose response screen, compounds were labeled as "Active" if they showed at least 8 fold increase over the ALLN control at any concentration.

Comment: Possible Artifacts: Possible artifacts in this assay include, but are not limited to, compounds that are fluorescent, absorb at the excitation or emission wavelengths, or non-specifically upregulate protein expression

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.

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.

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.
