PHARMACHOLOGIC EFFECT
Antituberculous antibiotic. It acts bacteriostatically or bactericidal, depending on the concentration in the focus of infection and the sensitivity of microorganisms. It is an analog of the amino acid D-alanine. The activity of L-alanine-racemase enzymes, which converts L-alanine to D-alanine, and D-alanyl-D-alanine synthetase, including D-alanine to the pentapeptide, necessary for constructing the bacterial cell wall, competitively depresses enzymes.
It is active against Mycobacterium tuberculosis, Mycobacterium avium.
