● 產品簡介：
Rifis highly active against Gram-positive bacteria,
such as staphylococci, streptococci, pneumococci but is less active against
Gram-negative organisms.Rifhas activity
against a wide range of microorganisms such as mycobacteria including Mycobacterium tuberculosis and M. leprae. The minimum inhibitory
concentrations (MIC) for the most sensitive microorganisms (chlamydia,
staphylococci) are in the range of about 0.01-0.02 μg/ml. The inhibitory
activity ofRifremained practically unchanged
between pH 5.5-8.0.Rifinhibits bacterial
DNA-dependent RNA polymerase (the enzyme responsible for DNA transcription) by
forming a stable enzyme-drug complex with the ?-subunit of RNA polymerase
(RNAP-Rif), rpoB gene (binding constant of 10-9 Mat37°C).Rifsuppresses the initiation of chain
formation (but not chain elongation) in RNA synthesis. There is some inhibition
of mammalian RNA polymerases at much higher concentrations ofRifthan that for bacterial RNA polymerases.Rifhas also antifungal activity probably due to some other mechanism of action
than inhibition of a fungal RNA polymerase.
