Protocol: Cation-adjusted Mueller Hinton II broth supplemented with 0.005% Tween-80 was inoculated with a single colony of S. aureus RN4220. Following overnight incubation, the culture was diluted 1:100 into fresh medium, and incubation was continued until the bacterial suspension reached an optical density at 600 nm (OD600) of 0.6, corresponding to a bacterial density of 5 x 10E8 colony forming units (CFU)/mL. An aliquot of this culture was diluted 1:400 with fresh medium and stored on ice until use. Assay plates were prepared for compound transfer in quadruplicate to enable screening of compounds at two temperatures in duplicate. The plate layout was as follows: wells in columns 1-22 were loaded with culture medium at 25 microL/well; wells in column 23 contained the screening negative control (medium only); wells in column 24 contained the screening positive control (medium containing 25 microg/mL chloramphenicol). 300 nL of experimental compounds were transferred by stainless steel pin array from library plate to assay plates.

25 microL of the bacterial suspension was added to each assay well. Assay plates were incubated at 42 degrees C in humidified chambers (humidity > 85%). After 20 h, the OD600 was measured using a plate reader in absorbance mode.

Comment: Data analysis description:

Absorbance values at 42 degrees C and 30 degrees C for each replicate were normalized to positive and negative control plate average absorbance, and replicate normalized values were averaged to calculate an average relative absorbance at both temperatures. A substance was considered a temperature-dependent positive at 42 degrees C if average relative absorbance <= 50 and the difference between relative absorbance at 30 degrees C and 42 degrees C >= 20 (relative absorbance 30 degrees C - relative absorbance 42 degrees C >= 20). A substance was considered a temperature-independent positive if relative absorbance at both 30 degrees C and 42 degrees C < 10.

Activity scores were calculated using average relative absorbance at both temperatures. Average relative absorbance <= 0 was scored as 100 for activity; average relative absorbance >= 100 was scored as 0 for activityy. Average relative absorbance between 0 and 100 was subtracted from 100 to generate activity scores for intermediate values (i.e. average relative absorbance = 40 corresponds to an activity score of 60).

Note that since this is treated as a panel assay, the query for active compounds includes many that were considered active at both temperatures. The final Pubchem activity score is the activity score at 42 degrees C, and compounds scored as active (PUBCHEM_ACTIVITY_OUTCOME = 2) include both temperature-dependent and temperature-independent active substances.

External ID: CBX7-Alpha-primary

Protocol: The protocol for the CBX7 AlphaScreen that we use is as follows: We create a standard alpha buffer (50mM HEPES, 150mM NaCl, 0.1% w/v BSA, 0.01% w/v Tween20) at pH 8.0 and make up two stock solutions at 2x final concentration in the alpha buffer. Solution A contains Human His6-CBX7 is used with biotinylated-H3K27me3 (residues 20-34), at 100nM and 50nM respectively. Solution B contains 20nM streptavidin donor beads and 20nM nickel acceptor beads. For 384 well assay formats, 10uL of solution A is added to each well of the assay plate and the plate is spun at 1000 rpm for 30 seconds. 100 nL of experimental ccompounds from stock plates are delivered by robotic pin transfer using a Janus Workstation (PerkinElmer), allowing the compounds to interact with CBX7 binding prior to assay measurement, followed by another spin and an incubation room temperature. Finally, 10uL of solution B is added to each well, the plate is spun again and then incubated at room temperature. AlphaScreen measurements are performed on an Envision 2104 (PerkinElmer) utilizing the manufacturer's protocol that has the correct excitation and emission wavelengths, cutoff filters, delay time, etc. We also do a crosstalk calculation through the Envision software to correct for luminescence for adjacent wells while reading the plate. The signal is then normalized to DMSO control wells on the compound plate prior to creation of the IC50 curves.

Protocol: Protocol:
PRC2 activity was measured using Dissociation-Enhanced Lanthanide Fluoro-ImmunoAssays (DELFIA) performed on 384-well, white, streptavidin-coated plates (PerkinElmer). In short, PRC2 was diluted to 30 ng and 3 ng per well in 20 uL 2X Enzyme Buffer (50mM Tris HCl pH 8.5, 10 mM DTT, 5 mM MgCl). Compounds were pinned at 100 nL per well and reactions were initiated with 20 uL of a 5 uM SAM (NEB) solution containing 600 nM H3[21-44]-GK-biotin (AnaSpec; PRC2).

Plates were incubated at room temperature for 1 hr and then washed three times with 100 uL of Wash Buffer (50mM Tris pH 7.4, 150 mM NaCl, 0.05% Tween 20, 0.2% BSA). 50 ul of Fluoroimmunoassay (FI) Buffer (50 mM Tris HCl pH 7.8, 150 mM NaCl, 0.05% Tween 40, 25 iM DTPA, 0.2% BSA, 0.05% BGG)containing a 1:4000 dilution of anti-H3K27me2 rabbit IgG (Cell Signaling, #9728) with 691 ng/mL Eu-N1-anti-rabbit IgG (PerkinElmer)was added to each well for PRC2 reactions.

Following 1 hr incubation at room temperature, the plates were washed three times with Wash Buffer and 50 uL of Enhancement Solution (PerkinElmer) was added to each well. Plates were incubated for 30 min at room temperature and time-resolved fluorescence (TRF) was measured on Wallac Envision 2104 Multilabel Reader (400 us window, 400 us delay, 320 excitation, 615 emission).

Comment: PRESENCE OF CONTROLS: Neutral control wells (NC) and positive control wells (PC) were included on every plate.

EXPECTED OUTCOME: Active compounds result in decreasing readout signal.

NORMALIZATION:
The raw signals of the plate wells were normalized using the 'Neutral Controls Minus Inhibitors' method in Genedata Assay Analyzer (v7.0.3):
The median raw signal of the intraplate neutral control wells was set to a normalized activity value of 0.
The median raw signal of the intraplate positive control wells was set to a normalized activity value of -100.
Experimental wells values were scaled to this range.
All well activities were then multiplied by -1 to create a positive activity readout value range, to match Pubchem convention.

PATTERN CORRECTION: No plate pattern correction algorithm from Genedata Condoseo (v.7.0.3) was applied.

PUBCHEM_ACTIVITY_SCORE:
This was set as equal to the mean of the normalized sample replicate activities, rounded to the nearest integer .
The minimum PUBCHEM_ACTIVITY_SCORE required for a compound to be called a hit (the activity threshold, or AT) was set at 50.

PERCENTAGE OF ACTIVE REPLICATES:
For each sample, the percentage of replicates (PCT_ACTIVE_REP) which had activity scores >= AT was determined.
The minimum percentage of replicates required for a compound to be called a hit (PAR_T) was set at 100.

PUBCHEM_ACTIVITY_OUTCOME:
Samples passing BOTH threshold criteria were assigned an outcome of 2 (active):
PUBCHEM_ACTIVITY_SCORE >= AT, and PCT_ACTIVE_REP >= PAR_T

Samples passing NEITHER threshold criteria were assigned an outcome of 1 (inactive):
PUBCHEM_ACTIVITY_SCORE < AT, and PCT_ACTIVE_REP < PAR_T

Samples passing AT only were assigned an outcome of 3 (inconclusive) :
PUBCHEM_ACTIVITY_SCORE >= AT, and PCT_ACTIVE_REP < PAR_T

Samples passing PAR_T only were assigned an outcome of 1 (inactive) :
PUBCHEM_ACTIVITY_SCORE < AT, and PCT_ACTIVE_REP >= PAR_T

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.
