Moenomycin A: The role of the methyl group in the moenuronamide unit and a general discussion of structure-activity relationships

Abstract Two disaccharide analogues 1b and 17a of moenomycin A have been synthesized and their antibiotic and transglycosylase-inhibiting properties have been determined. The results permit for the first time to arrive at a general view of the structural requirements in this class of compounds necessary to elicit antibiotic activity.
