Rufomycins
Webb15 juni 2000 · The present invention provides rufomycin factors and derivatives thereof, and pharmaceutical compositions thereof, which are useful as antimicrobials. WebbThe antimycobacterial peptides, rufomycins, have their antibiotic activity conferred by oxidative tailoring of the cyclic peptide. Here we elucidate the roles of cytochrome P450s RufS and RufM in regioselective epoxidation and alkyl oxidation respectively and demonstrate how RufM and RufS create a complex product profile dependent on redox …

WebbTo estimate the relative abundance of rufomycins, a calibration curve was created using fmoc-3-nitro-L-tyrosine monitoring the absorbance at max 355 nm. It was assumed that the extinction coefficients of fmoc-3-nitro-L-tyrosine and the 3 rufomycin compounds at 355 nm are the same. Solid amino acid was weighed and dissolved in Webb3 aug. 2024 · Recent Developments on the Synthesis and Bioactivity of Ilamycins/Rufomycins and Cyclomarins, Marine Cyclopeptides That Demonstrate Anti-Malaria and Anti-Tuberculosis Activity.

WebbRifamycin. The rifamycins are a group of antibiotics that are synthesized either naturally by the bacterium Amycolatopsis rifamycinica or artificially. They are a subclass of the larger family of ansamycins. Rifamycins are particularly effective against mycobacteria, and are therefore used to treat tuberculosis, leprosy, and mycobacterium avium ...
WebbThe rufomycins are neutral cyclic heptapeptides and are known to be very insoluble in water and require the presence of organic solvents for ready isolation. See US Patent No. 3,655,879. The use of organic solvents greatly increases the expense and complexity of isolating these factors, particularly at large scale, as well as greatly increasing the …
