Panoramica

Rifamycin S is a quinone and an antibiotic agnet against Gram-positive bacteria (including MRSA). Rifamycin S is the oxidized forms of a reversible oxidation-reduction system involving two electrons. Rifamycin S generates reactive oxygen species (ROS) and inhibits microsomal lipid peroxidation. Rifamycin S can be used for tuberculosis and leprosy.

• Descrizione: This compound belongs to the class of organic compounds known as macrolactams. These are cyclic amides of amino carboxylic acids, having a 1-azacycloalkan-2-one structure, or analogues having unsaturation or heteroatoms replacing one or more carbon atoms of the ring. They are nitrogen analogues (the a nitrogen atom replacing the o atom of the cyclic carboxylic acid group ) of the naturally occurring macrolides.
• External Descriptors: Ansamycins and related polyketides
