External ID: Sarm1 Tir NADase inhibitors screen

Protocol: NRK1-HEK293T cells were seeded onto 150 cm2 plates at 20 x 106 cells per plate. The next day, the cells were transfected with 15 microg FCIV-SST (SAM-TIR expression plasmid) using X-tremeGENE 9 DNA Transfection Reagent (Roche product #06365787001). The cultures were supplemented with 1 mM nicotinamide riboside at time of transfection to minimize toxicity from SAM-TIR overexpression. Forty-eight hours after transfection, cells were harvested, pelleted by centrifugation at 1,000 rpm (Sorvall ST 16R centrifuge, Thermo Fisher), and washed once with cold PBS (0.01 M phosphate buffered saline NaCl 0.138 M; KCl 0.0027 M; pH 7.4). The cells were resuspended in PBS with protease inhibitors (Complete protease inhibitor cocktail, Roche product # 11873580001) and cell lysates were prepared by sonication (Branson Sonifer 450, output = 3, 20 episodes of stroke). The lysates were centrifuged (12,000xg for 10 min at 4 degrees C) to remove cell debris and the supernatants (containing SARM1 SAM-TIR protein) were stored at -80 degrees C for later use in the in vitro SARM1 SAM-TIR NADase assay (see below). Protein concentration was determined by the Bicinchoninic (BCA) method.

This screen is an adaptation of the NAD/NADH Glo assay (Promega G9071). In this assay, NAD cycling enzymes convert NAD into NADH. In the presence of NADH, the reductase enzymatically converts a proluciferin reductase substrate into luciferin. Luciferin is detected using Ultra-GloTM rLuciferase, and the chemiluminescence intensity is proportional to the amount of NAD and NADH in the sample. In our diluted lysate alone, the amount of NAD and NADH is undetectable with this assay precluding any endogenous contribution to the final NAD detected. The assay was set up as follows: 2 microl candidate inhibitor (final concentration 1 microM, 2% DMSO), 0.07 microg lysate (2 microl), and 2 microl of 400 nM NAD. The reaction was incubated at 37 degrees C for 60 min, then 6 microl NAD/NADH Glo detection reagent was added. After 30 min at room temperature, the luminescent signals were quantified using a Cytation5 imaging reader (BioTek). The SARM1 SAM-TIR lysate catalyzed a dose-dependent depletion of NAD, whereas NAD levels did not decline when reactions were performed with lysate prepared from control NRK1-HEK293T cells.

Protocol: Black, standard capacity streptavidin-coated 384-well plates (Pierce 15407) were first washed with 50 L of phosphate buffer (100 mM, pH 7.0; PB7) three times using a Biotek 405 ELX plate washer. 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.

After 23 nL compound or DMSO vehicle was transferred into assay plate by a pintool work station (Kalypsys, San Diego, CA), fluorescence intensities in the assay plates were measured by an Envision (PerkinElmer, Shelton, CT) plate reader using three labels for measuring blue, green and red fluorescence at excitations 460, 535 and 590nm respectively.

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. Alternative analysis methods and interpretations of the data are available at EPA (http://actor.epa.gov) and NTP (http://tools.niehs.nih.gov/cebs3/ui/).

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 activators are ranked higher than compounds that showed apparent inhibition.
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: 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.
