Novel targets for tuberculosis drug discovery

Abstract

Since the determination of the Mycobacterium tuberculosis genome sequence, various groups have used the genomic information to identify and validate targets as the basis for the development of new anti-tuberculosis agents. Validation might include many components: demonstration of the biochemical activity of the enzyme, determination of its crystal structure in complex with an inhibitor or a substrate, confirmation of essentiality, and the identification of potent growth inhibitors either in vitro or in an infection model. If novel target validation and subsequent inhibition are matched by an improved understanding of disease biology, then new antibiotics could have the potential to shorten the duration of therapy, prevent resistance development and eliminate latent disease.
