title: Solid-phase synthesis and antibacterial evaluations of N-demethylvancomycin derivatives.
abstract: Twenty-five N-demethylvancomycin derivatives were synthesized on solid-support and their structures were determined by LC-MS/MS. Biological evaluation of these compounds indicated that bulky hydrophobic substituent on vancosamine of N-demethylvancomycin can increase antibacterial activity against vancomycin-resistant Enterococcus faecalis.
