Protocol: Assay Protocol Summary:

Two ul of enzyme-substrate mix was dispensed into medium binding white/solid 1536-well plates (Greiner Bio-One North America Inc., Monroe, NC) using a Flying Reagent Dispenser (FRD, Aurora Discovery, San Diego, CA). Test compounds dissolved in DMSO and positive control (ketoconazole) were transferred to the assay plates at 23 nl using a Pintool station (Wako, San Diego, CA). The assay plates were incubated at room temperature for 10 min. Then 2 ul of NADPH regeneration solution was added to each well of the assay plates using an FRD and incubated at room temperature for 1 h. The reaction was stopped by adding 4 ul of detection reagent using an FRD and after 20 min incubation at room temperature, the luminescence signal was measured using a ViewLux plate reader (Perkin Elmer, Shelton, CT). Data were expressed as relative luminescence units.

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.

Protocol: Microsomal Stability Assay
The substrate depletion method, also called the in vitro t1/2 method was used to analyze test compounds. Incubation and liquid handling were carried out using a previously described method (Shah et al., 2016). Briefly, each reaction mixture (110 muL) consisted of a test article (1 muM), human liver microsomes (0.5 mg/mL), and NADPH regenerating system in phosphate buffer at pH 7.4. Samples were incubated in 384-well plates at 37 degrees C for 0, 5, 10, 15, 30 and 60 min. At each time point, 10 muL of the incubation mixture was aspirated into another 384-well plate which contained cold acetonitrile (ACN) with internal standard (albendazole). All plates were centrifuged at 3000 rpm for 20 min at 4 degrees C, and the supernatants were transferred to a 384-well injection plate. Sample quantification and analysis was performed using a previously described method (Shah et al., 2016, Siramshetty et al., 2020). Compounds are classified as Unstable (t1/2 < 30 min) or stable (t1/2 > 30 min)

The interpretations presented here are based on the NCATS analysis methods.

Compound Ranking:
1. Phenotype compound classification is based on the half-life observed. Compound is "stable" if half-life (t1/2) is more than 30 minutes (class = 0); "unstable" if t1/2 is less than 30 minutes (class = 1). For this assay, stable compounds are ranked higher than compounds that are unstable.
2. PUBCHEM_ACTIVITY_OUTCOME corresponds to the phenotype observed. For all compounds with phenotype "stable", PUBCHEM_ACTIVITY_OUTCOME is "active". For all compounds with phenotype "unstable", PUBCHEM_ACTIVITY_OUTCOME is "inactive".

1. Briefly, 20 nL DMSO, positive control ZnAc (20nM final concentration), and test compounds were transferred into a 1,536-well solid bottom black plate (789176-F, Greiner One) via Echo 655 acoustic dispenser (Beckman Coulter). For primary screens, compounds were tested at 7 concentrations, 1:3 dilution points ranging from 25 uM to 34 nM. Follow-up confirmatory screens were carried out at 11 concentrations, 1:3 dilution points from 25 uM to 0.42 nM.
2. Four uL nsP2pro enzyme mix (150 nM final concentration) in 10 mM Tris-HCl pH 8.0 with 0.01% Tween 20 assay buffer was dispensed into the plate using a BioRAPTR FRD liquid dispenser (Beckman Coulter).
3. The plate was incubated at room temperature (protected from light) for 15 min
4. Four microliter of peptide 2 substrate (2.5 uM final concentration) in assay buffer was added to the plate.
5. After 1 hour, plates were immediately read on a ViewLux high-throughput CCD imager (Exposure = 10 sec, Gain = High, Speed = Slow, Binning = 2X). The above assay was also incorporated in the NCATS HTS facility41, which allowed for robotic liquid and compound dispensing, microplate handling, and fluorescence reading..
