3-Formyl Rifamycin SV

Product name:3-Formyl Rifamycin SV 
Product description:It is reddish crystalline powder.a family of antibiotics divided into naphthalenic ansamycins. Ansamycins are natural compounds characterized by a macrocyclic structure consisting of an aromatic ring system connected to an aliphatic chain that forms an amide linkage to the amino group of the aromatic moiety. 3-Amino-5-hydroxybenzoic acid (AHBA) is the start unit for the biosynthesis of ansamycins. Based on the structure of the AHBA derived aromatic moiety, this family of compounds can be further subdivided into a benzenic and a naphthalenic sub-group. Geldanamycins, ansatrienins, and ansamitocins are the benzenic ansamycins, which have been isolated from actinomycetes or higher plants. They are mainly cytotoxic agents against eukaryotes. the naphthalenic ansamycins, such as naphthomycins, streptovaricins, rifamycins, and tolypomycins, represent antibacterial activity against gram-positive cocci, some gram-negative bacilli, and Mycobacterium tuberculosis and certain other mycobacterial infections.
