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.

Protocol: Tox21 Assay Protocol Summary:

MDA-kb2 AR-luc cells were dispensed at 3,000 cells/4 uL/well of culture medium into white wall/solid-bottom 1536-well plates using a Multidrop Combi (ThermoFisher Scientific, Waltham, MA) dispenser. After the assay plates were incubated at a 37C and 0% CO2 for 5 hr, 23 nL of compounds dissolved in DMSO, positive controls or DMSO only was transferred to the assay plate by a Pintool station (Kalypsys, San Diego, CA), followed by addition of 1 uL of agonist (R1881) in culture medium using a Bioraptr Flying Reagent Dispenser (FRD) workstation (Beckman Coulter, Indianapolis, IN, USA). The plates were incubated at a 37C and 0% CO2 for 16 h. After 15.5 h incubation, 1uL of CellTiter-Fluor reagent (Promega) was added using a Bioraptr FRD to each plate for measuring cytotoxicity. The fluorescence intensity was quantified on a ViewLux plate reader (PerkinElmer, Shelton, CT) following 30 min incubation at 37C and 0% CO2.
