Comment: This summary is written for the purposes of summarizing the compound activities from the project combining the results from both the AR antagonist mode assay (AID 743042) and cell viability counter screen (AID 743041). For all inactive compounds, PUBCHEM_ACTIVITY_SCORE is 0. Active compounds have PUBCHEM_ACTIVITY_SCORE between 40 and 100. Potency and efficacy were used for determining relative score. Inconclusive compounds have PUBCHEM_ACTIVITY_SCORE between 5 and 30 determined by phenotype.

Protocol: DT40-hTDP1 cells without 20 nM Camptothecin (add 20 microL of DMSO in 1 L of cell culture medium) were dispensed at 400 cells/5microL/well in tissue culture treated 1536-well white wall/solid bottom assay plates (Greiner Bio-One North America, NC, U.S.A.) using a Multidrop Combi 8 channel dispenser (Thermo Fisher, Waltham, MA, USA). 23 nL compounds and controls were transferred using the pin tool (Kalypsys, San Diego, CA, USA) to the assay plates. The assay plates were then incubated at 37 masculineC for a minimum 48 hr. Three microL of Cell Titer Glo solution was added to the plates and incubated at RT in dark for 30 min. Luminescence was read using ViewLux (Perkin Elmer) with 1 sec exposure slow speed, high gain and 2x binning.

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.

The plates were incubated at 37 C and 5% CO2 for additional 30 min, and fluorescence intensity was measured by a ViewLux plate reader (PerkinElmer, Shelton, CT). For measuring luciferase reporter gene activity, 4 uL of ONE-Glo Luciferase Assay reagent (Promega) was added to each well using a Bioraptr FRD (Beckman Coulter), followed by 30 min incubation at room temperature. The luminescence intensity of plates was recorded by a ViewLux plate reader (PerkinElmer, Shelton, CT).

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.
