Rifampicin-d3 is a labeled version of Rifampicin (sc-200910). Rifampicin-d3 is a semi-synthetic antibiotic which inhibits the growth of bacteria by inhibiting RNA synthesis. It is known that Rifampicin-d3 inhibits RNA transcription by binding to the beta subunit of DNA-dependent RNA polymerase. Studies indicate that this antibiotic mostly inhibits the replication of gram-positive bacteria and Mycobacterium tuberculosis. One important feature of these bacteria is that their plasma membrane contains mycolic acid (sc-215402) and peptidoglycan complexes which enable the movement of the antibiotic into the cell. Furthermore, Rifampicin-d3 resistance is seen in bacteria and can potentially be reduced by the addition of ribosome inhibitors such as Chloramphenicol (sc-3594) or Streptomycin sulfate (sc-202821).
