Los ácidos micólicos, en específico, poseen funciones biológicas importantes, entre las que se encuentra el papel que desempeñan en la persistencia de la. como los ácidos micólicos, ácido micoserósido, fenoltiocerol, lipoarabinomanano y arabinogalactano contribuyen a la longevidad, a la respuesta inflamatoria. Aunque el análisis de los lípidos de la pared celular (ácidos micólicos) mediante cromatografía líquida de alta presión es una opción Buena y bien conocida, los.

Mechanism of action of diazaborines. A mechanism of drug action revealed by structural studies of enoyl reductase.

Tuberculosis, Mycobacterium smegmatis, lipids. Crystal structure and fuction of the isoniazid target of Mycobacterium tuberculosis. Biosynthesis of mycobacterial lipoarabinomannan: An application to a set of peptidometic rennin inhibitors.

Lepr Rev ; 68 4: Trends in Microbiology ;9 Inhibition of the Staphylococcus aureus NADPH-dependent enoyl-acyl carrier protein reductase by triclosan and hexachlorophene. The enoyl-reductases are essential enzymes in the fatty acids elongation pathway towards the mycolic acids, the main mycobacteria cell wall constituents, biosynthesis and so they are potential targets to the rational new antimycobacteria drug design.

Overexpression of inhA, but not kasAconfers resistance to isoniazid and ethionamide in Mycobacterium smegmatisM.

However, the biochemical and functional differences between the bacterial and mammals’ fatty acid synthetic pathway have endowed the mycobacterial enzymes with distinct properties. The mabA gene from the inhA operon of Mycobacterium tuberculosis encodes a 3-ketoacyl reductase that fails to confer isoniazid resistance. Crystallographic studies on the binding of isonicotinyl-NAD adduct to wild-type and isoniazid resistant 2-trans-enoyl-ACP CoA reductase from Mycobacterium tuberculosis.

These results indicate the relevance of continuing immunoprotection studies with mycobacterial lipid antigens. Characterization of a ligand-receptor binding event using receptor-dependent four-dimensional quantitative structure-activity relationship analysis.

High affinity InhA inhibitors with activity against drug-resistant strains of Mycobacterium tuberculosis. These provide valuable opportunities for structure- or catalytic mechanism-based design of selective inhibitors as novel anti-TB drugs with micolicso properties.

Probing mechanisms of resistance to the tuberculosis drug isoniazid: J Bacteriol ; Em geral, as tiofeno-diazoborinas foram os inibidores mais potentes, seguidos pelas benzo-diazoborinas e furano-diazoborinas, enquanto que as pirrol-diazoborinas foram totalmente inativas. Mycobacteria resistance to the drugs currently used in the therapeutics is the main cause of TB resurgence.
