Descripción

General description

Chemical structure: macrolide

Application

Rifamycin SV is a broad-spectrum semisynthetic antimicrobial agent of the rifamycin group. It is used to study potential genes, such as rif15 and rif16, which may be involved in the conversion of rifamycin SV into rifamycin B.

Biochem/physiol Actions

Rifamycin SV inhibits selective (E. coli, B. subtilis) bacterial DNA-dependent RNA polymerase by binding to the polymerase β-subunit, a mechanism similar to rifabutin. It acts as a selective cytochrome P450 3A4 inducer. It is active against Gram-positive bacteria and is moderately active against Gram-negative organisms.

Packaging
