External ID: LDHA

Protocol: The assay was optimized to 1536-well plates. Briefly, 3 muL of human lactate dehydrogenase 5 (#A38558H, Meridian Life Science, Inc., Memphis, TN) in LDH assay buffer (200 mM Tris HCl pH 7.4, 100 microM EDTA and 0.01% Tween-20) was added to a black solid bottom 1536-well assay plate (Greiner Bio-One) using a BioRAPTR FRD dispenser (Beckman Coulter, Brea, CA). A 1536-well pintool dispenser outfitted with 20 nL pins (Wako Automation, San Diego, CA) was used to transfer 23 nL of DMSO-solubilized compound (both library and vehicle controls) to each 1536-well assay plate. Following compound transfer, 1 muL of substrate solution containing NADH and sodium pyruvate (Sigma-Aldrich, St. Louis, MO) in LDH assay buffer was dispensed via BioRAPTR FRD to initiate the reaction. Final concentrations in the 4 microL reaction volume were 2 nM LDHA enzyme, 0.06 mM NADH and 0.2 mM sodium pyruvate. Following a 5 minute incubation period at room temperature, 1 muL of detection reagent (C. kluyveri diaphorase (Sigma-Aldrich) and resazurin sodium salt (Sigma-Aldrich) in LDH assay buffer) was added to a total volume of 5 muL. Final concentrations of detection reagents were 0.133 mg/mL diaphorase and 37 muM resazurin. Plates were immediately transferred to a ViewLux microplate imager (PerkinElmer, Waltham, MA), and any resulting resorufin fluorescence was measured (ex540, em590 nm) at 0 and 20 minutes. Fluorescence was normalized using enzyme-free and DMSO-treated control wells on each plate.

Comment: PubChem score indicates % inhibition at 229 uM or 114 uM of the compound (Max_response). Active compounds with Max_response greater than -100%, PUBCHEM_ACTIVITY_SCORE is 100. Active compounds with Max_response between -80% and -100%, PUBCHEM_ACTIVITY_SCORE is 80. Active compounds with Max_response between -60% and -80%, PUBCHEM_ACTIVITY_SCORE is 60. Active compounds with Max_response between -30% and -60%, PUBCHEM_ACTIVITY_SCORE is 40. Inconclusive Compounds with Max_response between -25% and -30% have PUBCHEM_ACTIVITY_SCORE 20. For all inactive compounds with Max_response greater than -25%, PUBCHEM_ACTIVITY_SCORE is 0

External ID: stopgo-p2-SytraCBC-dual-FF

Protocol: Reagents:
StopGo2A HEK-NPG-Luc cells and other necessary media and controls were provided by Dr. Atkins's lab. Compound PTC124 was used as a control. Dose response was assessed using a 1:2 dilution of control compound, with the top dose of 50uM final concentration. Background signal was normalized to wells treated with DMSO only.

Assay Protocol:
In brief, four microliters (2400 cells/well) of StopGo2A HEK-NPG-Luc cells were plated and incubated overnight at 37C. Twenty-three nanoliters of compounds and control were added to the wells using a 1536 array Kalypsys pintool workstation. After an over night incubation (at 37C) with compounds / control, 2.5 uL of Dual/Glo Firefly reagent was added. Firefly luciferase signal was obtained using the PerkinElmer ViewLux plate reader after 20min of room temperature incubation. Dual/Glo Renilla Lucifrase reagents were then added followed by additional 20 min room temperature incubation. Finally, the renilla luciferase signal was obtained using the PerkinElmer ViewLux reader.

Comment: Disclaimer:
Although all reasonable efforts have been made to ensure the accuracy and reliability of the data, caution should be exercised when interpreting the results as artifacts are possible from nonspecific effects such as assay signal interference. The curve fitting and activity calls presented here are based on the NCATS analysis methods.

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. For this assay, apparent inhibitors are ranked higher than compounds that showed apparent activation.
2. For all inactive compounds, with a ratio activity curve class of 4, 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. For a ratio activity curve class = -1.1, score = 80+abs((log_ac50+4.5)*inf_activity/20). For ratio.curve_class == -1.2 && abs(ratio.max_response) > 6*10, score = 60+abs((log_ac50+4.5)*inf_activity/20). For ratio.curve_class == -2.1 || ( ratio.curve_class==-2.2 && abs(ratio.max_response) > 6*10), score = 40+abs((log_ac50+4.5)*inf_activity/20). For ratio.curve_class == -1.2 || ratio.curve_class == -2.2, score = 20+abs((log_ac50+4.5)*inf_activity/20). Inconclusive compounds, with a donor curve class other than 4, have PUBCHEM_ACTIVITY_SCORE of 10. Inconclusive compounds have PUBCHEM_ACTIVITY_SCORE between 1 and 39.
