MIC data were converted into fractional inhibitory concentration (FIC), defined as ratio of the concentration of the antimicrobial at an inhibitory concentration with a second compound to the concentration of the antimicrobial by itself as previously reported [ 27].
In this assay, the SMN2-luciferase reporter cells were treated at six doses increasing from 124 nM to 30 µM of one compound and combined with either DMSO or a second compound at concentrations of 1.1, 3.3, or 10 µM.
