title: Moxifloxacin lethality against Mycobacterium tuberculosis in the presence and absence of chloramphenicol.
abstract: The C-8-methoxy fluoroquinolone moxifloxacin was more lethal against chloramphenicol-treated Mycobacterium tuberculosis than Bay y3114, a C-8-H cognate of moxifloxacin, and two C-8-methoxy fluoroquinolones, gatifloxacin and BMS-433368, which have different C-7 substituents. Thus, an optimal combination of C-7 and C-8 substituents is likely to be important for killing nongrowing M. tuberculosis.
