External ID: FATTTLab-Algae-Lipid

Protocol: Cells were pre-grown to mid-log phase in TAP media. For primary screen, cells were seeded at low density of 500,000 / well in 384-well plate. Compound in DMSO was added to each well at a final concentration of 10 micromolar and cells were allowed to grow for 72 hours. At the end of assay, Nile Red (30 uM f.c.) was added and plates were incubated at 37 C for 60 mins in dark. Fluorescence intensity was measured. Readouts were reported as normalized fold change in the intensity of treated versus control.

External ID: MCF7_OneDose

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.

External ID: ST2_IL33_Inhibitors_Primary_Screening_77700

Protocol: High-throughput screening was performed at Indiana University screening facility (Indiana University, Indianapolis, IN).

In summary, a mixture of ST2 and IL-33 was prepared by adding 0.30 microL of 14.1 microM recombinant human ST2-Fc Chimera and 0.30 microL of 55.25 biotinylated recombinant human IL-33 to 1.4 mL of assay buffer. In the HTS, each well of a 384-well Proxi-plate was first blocked by 100 microL of assay buffer for 1 h at room temperature. After removing the blocking buffer, 20 microL of ST2/IL-33 mixture was pipetted into each well and incubated at room temperature for 1 h followed by addition of compounds at 17 microM (0.8 microL) to each well and incubated at room temperature for 1 h. Ten microliters of 60 microg/mL anti-6xHis-conjugated AlphaLISA acceptor beads were added to each well and incubated at room temperature for 1 h before addition of 10 microL of 60 microg/mL of streptavidin-labeled AlphaLISA donor beads for incubation at room temperature for 30 min. Incubation of acceptor and receptor beads was conducted in darkness. The well with 3 nM ST2 alone was used as a negative control, whereas the ST2/IL-33 mixture with a human ST2 antibody added at 0.45 ng/microL was used as the positive control. Plates were read using the Envision Plate Reader. The buffer used in the assay contains 14.37 mL PBS, 30 microL Tween 20, and 600 microL of 5% bovine serum albumin in PBS.

Comment: PubChem active indicates >= 30% inhibition of ST2/IL-33 at 17 uM of the compound. Inconclusive: >=10% and < 30% inhibition.

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%.
