Balofloxacin (Q-35) is a fluoroquinolone antibiotic, in which a OMe group is substituted at the 8 position of the quinoline nucleus.
In vitro, it has a broad spectrum of activity against Gram-positive bacteria (eg.
Mycoplasma pneumoniae and
Staphylococcus aureus including MRSA) which is almost equal to that of sparfloxacin [
S0896] or tosufloxacin [
T2506]. In contrast, its activity against Gram-negative bacteria is lower. In animal studies, balofloxacin do not exhibit any phototoxicity which is a toxicity of fluoroquinolone antibiotic, in general.
