Chimeramycins: new macrolide antibiotics produced by hybrid biosynthesis.
Sir: Microbial conversion of antibiotically inactive macrocyclic lactones to active compounds is an important approach in the search for new macrolide antibiotics. Mutational biosynthesis originally proposed by SHIER et al.1) was proved useful also for constructing new macrolide antibiotics and many new derivatives were obtained. However, these were virtually inactive,2-1) or weakly active and ...
متن کاملHybrid biosynthesis of derivatives of protylonolide and M-4365 by macrolide-producing microorganisms.
Biotransformation of a macrolide antibiotic and a related compound was studied using various macrolide-producing microorganisms grown in the presence of cerulenin, an inhibitor of de novo synthesis of the aglycone moiety. Protylonolide (1) was transformed into 5-O-(4'-O-propionylmycarosyl)protylonolide (2) by a leucomycin-producing strain, Streptoverticillium kitasatoensis KA-429. M-4365 G2 (3)...
متن کاملAlbocycline: structure determination by x-ray crystallography.
The structure and absolute configuration of the macrolide antibiotic albocycline (1a) has been determined by X-ray crystallographic analysis on the derived p-bromobenzoate (1b). The absolute configuration of albocycline is 4R, 7S, 12S, 13R.
متن کاملSanctolide A, a 14-membered PK-NRP hybrid macrolide from the cultured cyanobacterium Oscillatoria sancta (SAG 74.79).
Sanctolide A (1), a 14-membered polyketide-nonribosomal peptide (PK-NRP) hybrid macrolide, was isolated from the cultured cyanobacterium Oscillatoria sancta (SAG 74.79). The planar structure was determined using various spectroscopic techniques including HRESIMS, and 1D and 2D NMR analyses. The relative configuration was assigned by J-based configurational analysis in combination with NOE corre...
