Fig. 1. — Screening the Library of Pharmacologically Active Compounds (LOPAC) set to identify redox cycling compounds (RCCs). (A) The 4 × 384-well plate overlay scatter plot of the % activation of H₂O₂ production data from the first iteration of the LOPAC screen. An ActivityBase™ HTS template was written to calculate the % activation based on the maximum (n = 32) and minimum (n = 24) plate controls for the HRP-PR H₂O₂ detection assay. A Spotfire^® visualization of the % activation data from 4 × 384-well plates of the HRP-PR H₂O₂ production data for the first iteration of the LOPAC screen overlaid in a single scatter plot is presented; () maximum (100 μM H₂O₂ in 1% Dimethyl Sulfoxide (DMSO), n = 32) plate controls, () minimum (1% DMSO, n = 24) plate controls, () 50% (50 μM H₂O₂ in 1% DMSO, n = 8) plate controls, and () 10 μM compounds in 0.8 mM DTT (1% DMSO, n = 320). (B) Chemical structures, names, and PubChem substance identity numbers (SIDs) of the RCCs identified in the LOPAC set. The chemical structures of 2,3-bis(2-hydroxyethylthio)naphthalene-1,4-dione (NSC 95397, PubChem-SID 400206), and 2,2-dimethyl-3,4-dihydro-2H-benzo[h]chromene-5,6-dione (β-lapachone, PubChem-SID 207115) are presented.
