Abstract
Derivatives of lactose with the galactose ring substituents replaced by deoxy or acylamino functions were prepared. The 2'-, 3'-. 4'- and 6'-deoxy, 3'-acetamido and 3'-benzamido derivatives of phenyl 4-O-(beta-D-galactopyranosyl)-beta-D-glucopyranoside (phenyl P-lactoside) were synthesized from disaccharide or monosaccharide precursors. The derivatives were tested as substrates for the N-acetylglucosaminyltransferase from Neisseria meningitidis, which uses lactosyl derivatives as acceptors and UDP-GlcNAc as the donor in a beta-(1-->3) glycosylation reaction. The 6'-deoxy derivative was nearly threefold as active as phenyl beta-lactoside, whereas the 2'- and 4'-deoxy derivatives were less active. The other derivatives were inactive, as expected.
