Rifampicin synthesis
WebRifampicin belongs to the rifamycin group of antibiotics and is used to treat numerous bacterial infections.This includes leprosy, tuberculosis and Legionnaire's disease. This medicine is administered either by mouth or intravenously. It works by interfering and preventing the production of RNA by bacteria. WebRifampicin is a wide-spectrum antibiotic in the frontline of the treatment of tuberculosis, leprosy, and other bacterial infections that are difficult to cure. ... Rifampin binds tightly to the beta subunit of bacterial DNA-dependent RNA polymerase, thereby inhibiting RNA synthesis. It is active in vitro against gram-positive and gram-negative ...

The rifamycins are a group of antibiotics that are synthesized either naturally by the bacterium Amycolatopsis rifamycinica or artificially. They are a subclass of the larger family of ansamycins. Rifamycins are particularly effective against mycobacteria, and are therefore used to treat tuberculosis, leprosy, and mycobacterium avium complex (MAC) infections.

WebApr 13, 2024 · Rifampin produces bactericidal antimicrobial activity by inhibiting DNA-dependent RNA polymerase (RNAP) either by sterically blocking the path of the elongating RNA at the 5′ end or by decreasing the affinity of the RNAP for short RNA transcripts. It specifically inhibits the microbial RNAP, halting further RNA synthesis. WebAug 5, 2024 · Rifampicin (also known as rifampin) inhibits RNA synthesis, and is used to treat tuberculosis, leprosy, staphylococcal infections and legionnaires’ disease.
