Abstract
Twenty-six episilon-rhodomycinone glycosides have been synthesized. These include the episilon-rhodomycinone glycosides of 2-deoxy-L-fucose, 2-deoxy-L-rhamnose, and 2-deoxy-D-ribose as well as their 2-hydroxyl derivatives. NMR spectroscopy showed that all the glycosides prepared had the saccharide residues linked to position 10 of episilon-rhodomycinone and helped establish the anomeric purity and configuration of several glycosides. Preliminary screening results show that 2-deoxy-di-O-acetyl-D-ribopyranosyl-episilon-rhodomycinone has an activity T/C of 125 on P388 tumors.
