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.

External ID: 6PGD_Inhibitor_Screening_2015_09

Protocol: The screening assay was performed in a 96-well reading plate, the reaction of each well is 200ul which contains:

50 mM Tris (pH 8.1),
0.2 mM 6-phosphogluconate,
1 mM MgCl2,
0.1 mM NADP+,
0.5 ug recombinant human 6PGD protein,
and 10 uM compound candidate.

The increase in absorbance at 341 nm was measured using a SpectraMax Plus spectrophotometer (Molecular Devices)

Comment: Please note:
This is primary screening data, and for further confirmation, compound that shows equal or over 20% inhibition of 6PGD enzyme activity in this assay is considered as a potential inhibitor.
