(a) Percent
inhibition of intramacrophage MTB (Cell line J774A.1,
murine origin) in the presence of 5d, moxifloxacin (MOX),
or isoniazid (INH). Concentrations: 5d (1 x MIC = 0.32
μg/mL; 5 x MIC = 1.6 μg/mL, and 10 x MIC = 3.2 μg/mL);
INH (1 x MIC = 0.06 μg/mL; 5 x MIC = 0.30 μg/mL, and 10
x MIC = 0.60 μg/mL); MOX (1 x MIC = 0.07 μg/mL; 5 x MIC
= 0.35 μg/mL, and 10 x MIC = 0.70 μg/mL). The results
are the mean and standard error of experiments performed in duplicate.
* = Statistically different from the untreated control (P < 0.05) by GraphPad Prism (One-way ANOVA with Dunnett’s
Multiple Comparison Post Test). (b) Intracellular activity of 5d via HT-SPOTi assay.
