Description

Rifamycin B is a rifamycin antibiotic that inhibits the bacterial enzyme DNA-dependent RNA polymerase. It is used to treat infectious diseases, such as tuberculosis and staphylococcal infections. Rifamycin B has been shown to be active against methicillin-resistant Staphylococcus aureus (MRSA) and penicillin-resistant Streptococcus pneumoniae. The process optimization of rifamycin B was performed by reacting the compound with inorganic acid, p-hydroxybenzoic acid, and metal hydroxides in order to improve its antimicrobial activity profile. Rifamycin B has also been shown to be an effective agent against resistant mutants of bacteria through surface methodology experiments.
