Abstract: The present invention relates to novel benzothiazinone derivatives and their use as antibacterial agents in infectious diseases of mammals (humans and animals) caused by bacteria, especially diseases like tuberculosis (TB) and leprosy caused by mycobacteria. The present invention aims at the generation of new compounds with activity against mycobacteria as potential new tuberculosis drugs to overcome problems concerning resistance and drug intolerance. The solution of the present invention is a compound of formula I wherein R1 to R6 are as defined in the specification.

Abstract: The present invention is directed to a method of selection of purified nucleotidic sequences or polynucleotides encoding proteins or part of proteins carrying at least an essential function for the survival or the virulence of mycobacterium species by a comparative genomic analysis of the sequence of the genome of M. tuberculosis aligned on the genome sequence of M. leprae and M. tuberculosis and M. leprae marker polypeptides of nucleotides encoding the polypeptides, and methods for using the nucleotides and the encoded polypeptides are disclosed.

Abstract: Multi-drug resistant strains of Mycobacterium tuberculosis represent a considerable threat to public health worldwide. Resistance to isoniazid (INH), a key component of anti-tuberculosis regimens, is often associated with loss of catalase activity and virulence. The katG gene, encoding HPI catalase-peroxidase, mediates INH-sensitivity and that the high level resistance encountered clinically may be due to deletions, insertions or point mutations which reduce or eliminate the expression of the catalase gene in the chromosomal region encompassing katG. INH-resistant strains of Mycobacterium tuberculosis are detected by nucleic acid hybridization with a unique nucleic acid sequence or by amplification techniques.
