Protocol: HCT116 colorectal cancer cells are infected with Ad-hTR-mut and cytotoxicity is assessed 5-days post infection, measured by standard MTT assay. Ad-hTR-mut constructed using the Adeasy system (Agilent) and purified and quantified using Adeno-x purification and rapid titre kits (Clontech). Cells are seeded at 10000 cells per well and infected with 500pfu/cell in 96 well plates (Costar) then incubated for 48h prior to addition of compounds. Compounds were screened at 10uM in duplicate 2 days post-infection and MTT assay performed 3 days later at 5 days post-infection. A negative control adenovirus was included on every plate as a control for non-specific viral toxicity and all wells were expressed relative to untreated cells. Absorbance at 570nm was determined using a Molecular Devices spectramax plus instrument and analysed using SoftMax Pro software. Hits were taken to be compounds giving greater than 2.5-fold increase in absorbance indicating increased cell survival.

Comment: Target cell viability at time of assay was 30-50% after infection with this stock of Ad-hTR-mut. Compounds giving 2.5-fold increase in survival relative to this condition were taken to be hits.

Protocol: NCI-60 Human Tumor Cell Lines Screen was performed using the standard one-dose NCI protocol, which is described in more detail at https://dtp.cancer.gov/discovery_development/nci-60/default.htm.

Compounds with GIPRCNT values below 10 were considered active. Activity score was based on GIPRCNT using the following formula:
max(-GIPRCNT/2 + 50, 0)
Score is 0 for GIPRCNT values of 100 or above, 50 for GIPRCNT values of 0, and 100 for GIPRCNT values of -100.

Comment: These data are a subset of the data from the NCI human tumor cell line screen. Compounds are identified by the NCI National Service Center (NSC) number, which is contained in the
PUBCHEM_EXT_DATASOURCE_REGID field. In the NCI cell line identification system, MCF7 is panel number 5, cell number 1. PANELCODE or PANELNAME identify the NCI-60 cell panel. PANELNBR does NOT identify the NCI-60 panel.

EXPID is the NCI internal tracking number for the experiment identifier, and PREFIX = 'S' for the NSCs submitted through the NCI Chemical Agents repository.

Substance concentration unit is indicated in the data table, using the following abbreviations: M = molar (M), u = micrograms/milliliter (microg/mL), V = volumetric fraction.

M_GIPRCNT represents the mean growth percent for that experiment, and N_GIPRCNT indicates the number of values for that NSC within an experiment, while STDEV_GIPRCNT is the standard deviation. Most NSCs are tested once per experiment, resulting in EXP_COUNT = 1.

Protocol: N/A

Comment: Compounds with any of Ki, IC50, Kd, or EC50 activity value <= 10uM are labeled as "Active".
If multiple measurements are available for a given compound, it is labeled as "Active" if any of the measurements meet the criterion. Activity values are checked in the order of Ki, IC50, Kd, and EC50. The first entry that meets the above activity threshold is used to determine "Standard Type", "Standard Relation", and "PubChem Standard Value". Otherwise, the first non-empty entry will be used to set those values.

Protocol: 1; Dispense 45 nl compounds (10 mM stocks) using ECHO 555 to Alpha 384 well assay plates. Dispense 45 nl DMSO to control columns 1 and 2 of 384 well plates.
2; Incubate 5 ul of 6XHis-mHTT (Final, 13 nM) with the compounds for 40 mins at room temperature in buffer containing 10 mM Tris.HCl pH 7.4, 1 mM calcium chloride, 150 mM sodium chloride, 0.1% BSA and 20% glycerol.
3; Dispense 5 ul of 6XGST-CaM (Final 13 nM) in buffer A.
4; Incubation; 1 hour (dark at 25C)
5; Dispense 20 ul of Nickel chelate acceptor beads (Final, 20 ugs/ml) and Glutathione donor beads (Final, 30 ugs/ml). Incubate for 2h, room temperature.
6; Detector: Perkin Elmer Enspire, Alphascreen Module (Excitation 680nm/Emission 570nm).

NOTES (numbers refer to Sequence numbers above)
1. Alphascreen bead incubations were performed in green light, TiterTek setting 400rpm.
2. All incubation and addition steps were followed by mixing and centrifugation at 400g,1 min.
3. The percent inhibition for each compound was calculated as follows:
100- [100 *((Test Compound-Median Low Control) / (Median High Control - Median Low Control))]

Where:
Test_Compound is defined as wells containing His mHTT + GST CaM in the presence of test compound

High_Control is defined as wells containing His mHTT + GST CaM and DMSO.

Low_Control is defined as wells containing His mHTT and DMSO.

Comment: All percent inhibition data reported were normalized to high and low controls on a per-plate basis. The results of primary screening data include compounds contributing to assay signal interference, interference with tags binding to Alpha beads, chelators, process related artifacts etc.. The actives were defined as compounds that inhibited Alphascreen reads to greater than 50%.
