naturally-occurring glycopeptide antibiotic, differing fromvancomycin in the stereochemistry of the amino-sugar of the disaccharide function, and the presence of a third sugar attached at the benzylic position of amino acid residue 6. Despite these seemingly subtle differences, LY264826 is approximately 10 times more active than vancomycin against the enterococci. In the pursuit of new antibiotics active against multiresistant
