Chemical Properties:
  1. Rifaximin is an antibiotic structurally related to rifamycin. It is reported to be efficacious in the treatment of gastrointestinal infections and hepatic encephalopathy, being highly active against Gram-positive and -negative aerobic and anaerobic bacteria. Due to poor systemic absorption, rifaximin is effective in presurgical sterilization of the GI tract.It displays good activity against a wide spectrum of bacteria, including Salmonella spp., S. aureus, and E. coli.
  2. The mechanism of action of pyrazinamide is unknown, but recent findings suggest that pyrazinamide may be active either totally or in part as a pro-drug. Susceptible organisms produce pyrazinamidase, which is responsible for conversion of pyrazinamide to pyrazinoic acid intracellularly. Mutation in the pyrazinamidase gene (pncA) results in resistant strains of M . tuberculosis. Pyrazinoic acid has been shown to possess biological activity at a pH 5.4 or lower, in contract in vitro tests that show pyrazinoic acid is 8- to 16-fold less active than pyrazinamide . Pyrazinoic acid may lower the pH in the immediate surroundings of the M . tuberculosis to such an extent that the organism is unable to grow, but this physicochemical property appears to account for only some of the activity. The protonated pyrazinoic acid also can permeate the mycobacterial membrane to lower the pH of the cytoplasm. Recent evidence suggests that pyrazinoic acid decreases membrane potential in older, nonreplicating bacilli, thus decreasing membrane transport, and interferes with the energetics of the membrane.
Application:
  1. Rifaximin antibacterial, RNA synthesis inhibitor
  2. Rifaximin muscle Relaxant
  3. Rifaximin Non-absorbable semisynthetic Rifamycin antibiotic
  4. ChEBI: A semisynthetic member of the class of rifamycins and non-systemic gastrointestinal site-specific broad spectrum antibiotic. Used in the treatment of traveller’s diarrhoea, hepatic encephalopathy and irritable bowel syndrome.
  5. It is used for a variety of gastrointestinal diseases, including the treatment of traveler’s diarrhea. Preliminary results suggest clinical efficacy in the therapy of hepatic encephalopathy and of C. difficile infections.
