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.

Protocol: C-terminally 6xHis tagged CDK2/Cyclin A complex and N-terminally Flag tagged CDC25B C473S (372-566) were expressed and purified. Proteins were incubated together at a final concentration of 125 nM each for 1 hr prior to incubation with compound for 1 hr, followed by addition of anti-6xHis europium cryptate donor beads (Cisbio) and anti-Flag XL-665 acceptor beads (Cisbio) at a final dilution of 1:350 for 1 hr. 20mM potassium fluoride was added 10 minute prior to plate reading. Assay reagents were dispensed using a multidrop liquid dispenser (Thermo Scientific) onto uncoated, black, low-volume, 384-well plates (Corning). Assay plates were quantified using an Envision plate reader (Perkin-Elmer) with excitation of the europium crytate donor at 337 nm wavelength and emission of the donor at 620 nm and emission of the XL-665 acceptor at 665 nm in 18 uL volumes. Assays were performed in a buffer containing 50 mM Tris (pH 7.5), 50 mM NaCl, 10mM MgCl2, 1mM TCEP, with addition of and 1mM ATP, 0.05% BSA, and 0.05% Tween-20 immediately prior to the start of the assay.

Comment: The activity outcome is based on a Z-score (number of standard deviations from the negative control mean) of 3 or higher on at least 50% times that the sample was screened.
For instance, if the sample was screened in n=4 runs, it would be considered active only if it had a Z-score of 3 or above in at least 2 runs.

This screen was funded by NIH grant number: R01CA181185
