Fig. 4: The effects of commonly used antibiotics and Mito-PEG-ATO analogs on the proliferation of gram-positive and gram-negative bacteria.

The effects of commonly used antibiotics (chloramphenicol [Cam] and ampicillin [Amp]), Mito-PEG2-ATO, and Mito-PEG5-ATO on the proliferation were monitored at OD600 for 6 h in gram-positive E. faecalis (a) and S. aureus (b) and in gram-negative E. coli (c) and P. aeruginosa (d). Data shown are the mean ± SD, n = 4.
