Biological Activity:
Fleroxacin(Quinodis) is a new broad-spectrum fluoroquinolone. In a study, fleroxacin significantly inhibited cell proliferation in a dose- and time-dependent manner at concentrations of 50-800 microg/mL for 12, 24, and 48 hours. The inhibitory effects of fleroxacin combined with 5-FU appeared synergistic using normalized isobologram and combination index analysis. In vivo, no significant changes in bladder tumor frequency were noted between the control and fleroxacin and 5-FU groups. Significant inhibition of tumor frequency was observed only when fleroxacin was administered with 5-FU.Fleroxacin combined with 5-FU inhibited the proliferation of bladder tumor cell lines both in vitro and in vivo. This combination therapy might be applicable in clinical settings. [1] |
