Molecular formula: C50H88N28O15

Little is known about capreomycin's exact mechanism of action, but it is thought to inhibit protein synthesis by binding to the 70S ribosomal unit. Capreomycin also binds to components in the bacterial cell which result in the production of abnormal proteins. These proteins are necessary for the bacteria's survival. Therefore the production of these abnormal proteins is ultimately fatal to the bacteria. Aminoglycosides are usually bactericidal in action. Although the exact mechanism of action has not been fully elucidated, the drugs appear to inhibit protein synthesis in susceptible bacteria by irreversibly binding to 30S ribosomal subunits. /Aminoglycosides/ Capreomycin is an important drug used for TB with multi-drug resistance. A recent study also indicates that this drug possesses unique bactericidal activity against non-replicating TB bacilli among known anti-TB drugs. Thus, there is an urgent need for investigating the full-spectrum action of capreomycin. Here /investigators/ conduct the first microarray-based study on capreomycin using the high-resolution Affymetrix oligonucleotide GeneChip system. The results indicate that capreomycin primarily acts on the information pathways but it also significantly affects cell wall, cell processes, intermediate metabolism and respiration in Mycobacterium tuberculosis. This study not only transcriptionally validates the specific molecular target, 16S rRNA, but also discovers potential new targets of capreomycin, including genes operating at the DNA level, such as Rv0054 (ssb) and Rv3715c (recR), as well as genes involved in cell division like Rv3260c (whiB2). In addition, the nuo gene cluster and the ATP synthase gene cluster are repressed.
