คำอธิบายสินค้า

Product Description
 
D-cycloserine is a peptide class of broad-spectrum antibiotics produced or chemically synthesized by Streptomyceslavendulae and S.orchidaceus. White crystal, hygroscopic, easy to dissolve in water, soluble in low alcohol, ace tone and dio xane, difficult to dissolve in chloro form and petroleumether; In alkaline solution is relatively stable, in acidic and neutral solution is rapidly decomposed. Cycloserine has a wide antibacterial spectrum, in addition to mycobacterium tuberculosis, most gram-positive and negative bacteria, rickettsia and some protozoa also have an inhibitory effect on strep tomycin, violamycin, p-aminosalicylic acid, iso niazid, pyra zinamide and other drug-resistant mycobacterium tuberculosis. Cycloserine had a mild synergistic effect with iso niazid on mycobacterium tuberculosis H37RV, but showed neither synergistic nor antagonistic effect with strep tomycin. This product is bacteriostatic agent, increase the dose or prolong the time of action with bacteria, also does not appear bactericidal effect. The mechanism of antibacterial action of D-cycloserine is to inhibit the biosynthesis of cell wall peptidoglycan, because it is the structural analogized of D-alanine, it can competitively inhibit two important Chemicalbook enzymes in the process of peptidoglycan synthesis, namely alanine racemase and D-alanyl-d-alanine synthetase. The ability of the anti mycobacterium tuberculosis (Mycobacteriumtuberculosis) weak, only 1/10 ~ 1/20 for strep tomycin. The advantage is that it is effective against the resistant strains of the bacterium, and it is not easy to develop resistance to it. This product can be used in combination with other antituberculosis agents to treat tuberculosis caused by drug-resistant Mycobacterium tuberculosis. Cycloserine is a second-line anti-tuberculosis drug, which can inhibit the growth of mycobacterium tuberculosis, but its effect is weaker than that of first-line drugs, and its efficacy against tuberculosis is also lower. Drug resistance can be generated by single use, but drug resistance occurs more slowly than other anti-tuberculosis drugs, and there is no cross-resistance between cycloserine and other anti-tuberculosis drugs. Its antibacterial mechanism is to inhibit the synthesis of mucopeptide in bacterial cell wall, thus causing cell wall defects. The main structural component of bacterial cell wall is the cell wall mucopeptide, which is formed by repeated and alternating binding of n-acetylglucosamine (GNAc) and N-acetylmicylic acid (MNAc) which is associated with pentapeptide. The formation of intracytoplasmic mucopeptide precursors is hindered by cycloserine, which inhibits the formation of n-acetyl-paraceptides by inhibiting D-alanine racemase and synthetase.
