IBG inhibits S. aureus growth without detectable mutant development. (A) Structure of IBG. (B) Viability of S. aureus ATCC 29213 treated with IBG or VAN. (C) Viability of MRSA ATCC 43300 treated with IBG or VAN for 4 h. (D) IBG treatment could not result in S. aureus ATCC 29213 lysis; (E) Appearance of spontaneous IBG and CIP-resistant S. aureus mutants over 100 days of serial passages. IBG, isopropoxy benzene guanidine; VAN, vancomycin; CIP, ciprofloxacin; Individual data points (n = 3 biologically independent experiments) and mean ± SD. are shown.
