Background:
Rifampicin-d3is intended for use as an internal standard for the quantification of rifampicin by GC- or LC-MS. Rifampicin is a rifamycin antibiotic and inhibitor of bacterial RNA polymerase (IC50= 0.01 μg/ml for theE. colienzyme).1It inhibits the growth ofM. tuberculosisH37Rv in mouse peritoneal macrophages (MIC = 0.8 μg/ml) as well as clinical isolates of various species ofStaphylococcus,Streptococcus,Haemophilus, andNeisseria(MICs = 0.009-1.4 μg/ml).2,3Rifampicin increases survival in a mouse model of tuberculosis infection.3It is also an agonist of the human pregnane X receptor (PXR; EC50= ~2 μM).4Formulations containing rifampicin have been used in the treatment of tuberculosis and meningococcal carriers.
