Modest potentiation of the genotoxic effect of MMS exhibited by 16 prioritized hits (designated I in Table S1).

<p>HeLa cells were exposed to a dilution series of each compound shown in the absence (empty squares) and presence of 400 µM MMS (filled squares), and after a 24-hour incubation the cell viability was measured by ATP-content detection using CellTiter Glo. Results are presented as averages and standard deviations from duplicate samples, normalized against vehicle control.
