Abstract
A collection of 24 rifampin-resistant clinical isolates of Mycobacteri um tuberculosis with characterized RNA polymerase beta-subunit (rpoB) gene mutations was tested against the antimycobacterial agents rifampi n, rifapentine, and KRM-1648 to correlate levels of resistance with sp ecific rpoB genotypes. The results indicate that KRM-1648 is more acti ve in vitro than rifampin and rifapentine, and its ability to overcome rifampin resistance in strains with four different genetic alteration s may prove to be useful in understanding structure-function relations hips.
