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.

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.

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.

Protocol: Cybrid cells were washed with PBS, trypsinized, spun down at 300g for 5 minutes, and resuspended in 10 mLs of PBS. Cells were counted, and the appropriate amount of cells were added to a vial containing DMEM (No Glucose) + 2%FBS + 1% P/S + 10mM Galactose, DMEM (No Glucose) + 2%FBS + 1% P/S + 10mM Galactose + 0.3% DMSO, DMEM No Glucose + 2% FBS + 1% P/S + 10mM Galactose + 1uM I-BET GSK 525762A, or DMEM (No Glucose) + 2%FBS + 1% P/S + 10mM Galactose + 1.25mM Glucose. Cells were then seeded in a Corning 3570 384-well plate (40 ul/well,1500 cells/well). Two replicates were prepared as described at the same time per library plate.

100 nl of compound was added to each well via pin transfer immediately after seeding. After the addition of compound, cells were incubated for 72 hours at 37 degrees C with 5% CO2.

Following the 72 hour incubation period, the 384 well plates were centrifuged for 1 minute at 1000 rpm. The media was aspirated using an aspiration wand and fresh media DMEM only, was added to the cells (40uL/ well) using a well-mate. Fifteen-microliters of Cell Titer Glow substrate was then added to each well using the well-mate. The plates were gently vortexed for 10 seconds and then centrifuged for 1 minute at 1000 rpm. The plates were then immediately read on the Envision instrument and the luminescence was detected for each individual well.

Positive control (strong): Cells seeded in DMEM (No Glucose) + 2%FBS + 1% P/S + 10mM Galactose + 1.25mM Glucose
Positive control (weak): Cells seeded in DMEM No Glucose + 2% FBS + 1% P/S + 10mM Galactose + 1uM I-BET GSK 525762A
Negative control: Cells seeded in DMEM (No Glucose) + 2%FBS + 1% P/S + 10mM Galactose + 0.3% DMSO

Comment: Data analysis method and criteria for scoring active compounds:

Z-scores were calculated for both replicates separately using the plate average and standard deviation of experimental well luminescence (Z = (x - mu)/sigma). Compounds were considered active if both replicate Z-scores >= 1.8. Activity scores were determined by scaling replicate average Z-scores from 0 (activity score = 0) to 4 (activity score = 100), with activity score > 45 being considered active. Z-scores < 0 were set to activity score = 0; Z-scores > 4 were set to activity score = 100 (100% activity).

Subsequently, 5 L of biotinylated pre-miRNA substrate (500 nM final) was dispensed into the plate using a Multidrop Combi Reagent Dispenser (Thermo Scientific). Plates were then centrifuged for 1 min at 1,000 RPM (223 g), sealed with plate tape, and incubated overnight at 4 C. The following morning, plates were washed three times with 50 L of PB7, followed by the addition of 5 L of Dicer digest buffer (20 mM Tris, 12 mM NaCl, 2.5 mM MgCl2, 1 mM fresh DTT, and 4.5% DMSO) and centrifugation. Compounds (50 nL of 5 mM DMSO stock, 25 M final) were then added into the sample wells using a Sciclone (Caliper) liquid handler with V&P pintool; the same volume of DMSO was added to the control wells. The plates were incubated at 25 C for 15 min before addition of 5 L of digest buffer containing 217 g/nL Dicer (108 g/mL Dicer, 5% glycerol and 0.01% Triton X-100 final, excess with respect to pre-miRNA). For the positive control wells, digest buffer without Dicer was added. The plates were centrifuged again and resealed before being placed in a 37 C incubator for 5 h. After Dicer cleavage, plates were washed three times with 50 L of PB7. mTet-HRP in PB7 (10 L, 750 nM final) was then dispensed into each well. The plates were subsequently centrifuged, sealed, and incubated at 25 C for 2 h. Plates were then washed three times with 50 L of wash buffer (2 mM imidazole, 260 mM NaCl, 0.5 mM EDTA, 0.1% Tween-20, pH 7.0), followed by washing three additional times with 50 L of PB7. Finally, SuperSignal West Pico (25 L; Pierce) was added, the plates were incubated at 25 C for 5 min, and chemiluminescence signal was detected using a PHERAstar plate reader using LUM plus module (BMG Labtech).

Comment: The activity outcome is based on a Z-score (number of standard deviations from the negative control mean) of 3 or higher on at least 50% times that the sample was screened.

For instance, if the sample was screened in n=4 runs, it would be considered active only if it had a Z-score of 3 or above in at least 2 runs.

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: Two uL of HEK293 cell suspension are dispensed at 1000 cells/well into solid white 1536-well plates (Grenier) using a Multidrop Combi (Thermo Scientific). After addition of 23 nL compound by a pin tool (Kalypsys), the plate is incubated 1 h at 37 degrees C and then 3 uL of virus 1:100 dilution VSV-MARV is added. After 28 hr, 4 uL of assay reagent is added and the plates are read using a ViewLux (Perkin Elmer). Assays are performed in sub-saturating amounts of virus (MOI <0.5), therefore luciferase signals reflect the amount (titer) of virus able to infect the cells in presence of the compound.

Comment: Compound Ranking:
