一般描述

Chemical structure: macrolide

应用

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.

生化/生理作用

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.

The formation of Mn2+- or Cu2+-rifamycin SV complex and the semiquinone radical of rifamycin SV was studied by electron spin resonance spectroscopy. The results indicate that: (1) the complexes Mn2+-rifamycin SV (g parallel = 2.265, g perpendicular = 2.087, A

Although small molecules that modulate amyloid formation in vitro have been identified, significant challenges remain in determining precisely how these species act. Here we describe the identification of rifamycin SV as a potent inhibitor of β(2) microglobulin (β(2)m) fibrillogenesis when

Macrolide antibiotics azithromycin (AZI) and clarithromycin (CLARI) are large molecular weight compounds and are substrates for apically polarized efflux transporters such as P-glycoprotein, which can potentially restrict intestinal absorption. However, despite these undesired physicochemical and biopharmaceutical properties, AZI and CLARI

Amycolatopsis, genus of a rare actinomycete, produces many clinically important antibiotics, such as rifamycin and vancomycin. Although GlnR of Amycolatopsis mediterranei is a direct activator of the glnA gene expression, the production of GlnR does not linearly correlate with the
