General description
Rifamycin S is a chemical compound that belongs to the class of antibiotics known as rifamycins. It is a natural product produced by the bacterium Amycolatopsis mediterranei and is used primarily as a reference standard for the detection and quantification of rifamycins in various samples. Rifamycin S is chemically related to other rifamycin antibiotics, including rifampicin.
Application
However, it has been used as a precursor in the synthesis of other rifamycin antibiotics, and it has also been used in research studies to investigate the mechanism of action and resistance of rifamycin antibiotics.
Biochem/physiol Actions
Rifamycin S inhibitions bacterial RNA synthesis. Rifamycin S works by binding to a specific subunit of the bacterial RNA polymerase enzyme, which is necessary for the initiation of bacterial RNA synthesis. Binding of Rifamycin S to the RNA polymerase enzyme inhibits its activity, thereby preventing the transcription of bacterial genes into RNA molecules that are essential for bacterial survival. This leads to the inhibition of bacterial growth and ultimately, bacterial death. Rifamycin S has a broad-spectrum activity against different bacterial species.
