Metabolite Identification
Common Name25-O-Desacetyl rifabutin
Description25-O-Desacetyl rifabutin is a metabolite of rifabutin. Rifabutin (Rfb) is a bactericidal antibiotic drug primarily used in the treatment of tuberculosis. The drug is a semi-synthetic derivative of rifamycin S. Its effect is based on blocking the DNA-dependent RNA-polymerase of the bacteria. It is effective against Gram-positive and some Gram-negative bacteria, but also against the highly resistant Mycobacteria, e.g. Mycobacterium tuberculosis, M. leprae and M. avium intracellulare.

Chemical Taxonomy
Description Belongs to the class of organic compounds known as naphthofurans. Naphthofurans are compounds containing a furan ring fused to a naphthalene moiety. Furan is a 5 membered- ring aromatic ring with four carbon and one oxygen atoms. Naphthalene is a polycyclic aromatic hydrocarbon made up of two fused benzene rings.
