Biosynthetic Origin of the Atypical Stereochemistry in the Thioheptose Core of Albomycin Nucleoside Antibiotics

Albomycins are peptidyl thionucleoside natural products that display antimicrobial activity against clinically important pathogens. Their structures are characterized by a thioheptose with atypical stereochemistry including a d-xylofuranose ring modified with a d-amino acid moiety. Herein it is demonstrated that AbmH is a pyridoxal 5′-phosphate (PLP)-dependent transaldolase that catalyzes a threo-selective aldol-type reaction to generate the thioheptose core with a d-ribofuranose ring and an l-amino acid moiety. The conversion of l-to d-amino acid configuration is catalyzed by the PLP-dependent epimerase AbmD. The d-ribo to d-xylo conversion of the thiofuranose ring appears according to gene deletion experiments to be mediated by AbmJ, which is annotated as a radical S-adenosyl-l-methionine (SAM) enzyme. These studies establish several key steps in the assembly of the thioheptose core during the biosynthesis of albomycins.

, p. 591 - 594 (2007/10/03)
A practical synthesis of 4′-thioribonucleosides starting from inexpensive l-arabinose is described. 1,4-Anhydro-2,3-O-isopropylidene-4- thioribitol, which was prepared by using a novel reductive ring-contraction reaction, was converted to the 5-O-silylated sulfoxides. The Pummerer-type thioglycosylation of the sulfoxides gave the 4′-thioribonucleosides stereoselectively.
