S. Riedel et al., Synthesis and transglycosylase-inhibiting properties of a disaccharide analogue of moenomycin A lacking substitution at C-4 of unit F, TETRAHEDRON, 55(7), 1999, pp. 1921-1936
A disaccharide analogue (A4 = 13c) of moenomycin A lacking the OH group in
the 4-position of the uronic acid moiety has been synthesized using the Sai
to deoxygenation reaction as key step. 13c does not inhibit the transglycos
ylase (PBP 1b), a key enzyme in the biosynthesis of bacterial peptidoglycan
. The result demonstrates the importance of this OH group for the binding o
f disaccharide moenomycin analogues to the enzyme. (C) 1999 Elsevier Scienc
