Compound Ranking:
1. Compounds are assayed at single point activity (40 uM).
2. Active / Inactive compound calling is based on the results of the enzyme assay panel. ACTIVE compounds have PUBCHEM_ACTIVITY_SCORE = 50 and are compounds that have <= -50% max response in ANY ONE of the six enzymes. INACTIVE compounds have PUBCHEM_ACTIVITY_SCORE = 0 and are those that have >= -30% max response in ALL SIX enzymes. The remaining compounds are INCONCLUSIVE and have PUBCHEM_ACITIVITY_SCORE = 30.

Protocol: Assay Protocol Summary:

Two ul of enzyme-substrate mix was dispensed into medium binding white/solid 1536-well plates (Greiner Bio-One North America Inc., Monroe, NC) using a Flying Reagent Dispenser (FRD, Aurora Discovery, San Diego, CA). Test compounds dissolved in DMSO and positive control (ketoconazole) were transferred to the assay plates at 23 nl using a Pintool station (Wako, San Diego, CA). The assay plates were incubated at room temperature for 10 min. Then 2 ul of NADPH regeneration solution was added to each well of the assay plates using an FRD and incubated at room temperature for 1 h. The reaction was stopped by adding 4 ul of detection reagent using an FRD and after 20 min incubation at room temperature, the luminescence signal was measured using a ViewLux plate reader (Perkin Elmer, Shelton, CT). Data were expressed as relative luminescence units.

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.

External ID: NSD2-synergy-p-2C

Protocol: High-throughput drug screening of isogenic RCH-ACV cell lines was performed at the National Center for Advancing Translational Science (NCATS), National Institutes of Health as previously described (1). Briefly, isogenic RCH-ACV NSD2 p.E1099K mutant (9B) and WT cells (2C) were plated at 500 cells/well in a 1536-well plate with a 72-hour incubation with compounds prior to addition of CellTiter-Glo to assess cell viability. NCATS libraries screened include: NPC, MIPE 5.0, Kinase and NPACT. To determine compound activity in the qHTS assay, the concentration-response data for each sample was plotted and modeled by a four-parameter logistic fit yielding IC50 and efficacy (maximal response) values. The area under the curve (AUC) of the dose-response curve ensures both efficacy (magnitude of cell killing) and potency (concentration that elicits cell killing) are accounted for in the analysis of activity.
