| pubmed-article:11811618 | pubmed:abstractText | Sparfloxacin, a difluorinated quinolone is a potent anti-mycobacterial agent used in the treatment of mycobacterial infections. We have investigated whether sparfloxacin had other, more subtle effects on mycobacteria besides its interaction with DNA gyrase that could contribute to its therapeutic efficacy. Mycobacterium smegmatis cells grown in media with sub-inhibitory concentration of sparfloxacin were observed to have significant reduction in the biosynthesis of vital macromolecules, as shown by the incorporation of various radiolabelled precursors. The analysis of subcellular distribution of phospholipids of sparfloxacin-treated cells demonstrated an increase in the cell membrane and reduction in the cell wall, suggesting changes in the cell envelope architecture by sparfloxacin. Significant changes were also observed in other chemical constituents of the cell wall, especially in the arabinose and glucosamine contents. Mycolic acids, the major component of mycobacterial cell wall were reduced in the presence of MIC50 of sparfloxacin. There was a decrease in the limiting fluorescence intensity (Fmax) of 1-anilinonaphthalene 8-sulfonate (ANS) indicating alterations in the organization and conformation of mycobacterial cell surface. These results suggest that the mechanism of action of anti-mycobacterial action of sparfloxacin involves mycobacterial cell envelope. | lld:pubmed |
