  • Patent number: 6274716
    Abstract: A combinatorial chemical library of compounds structurally related to the moenomycin class of antibiotics has the formula wherein D is a donor mono- or disaccharide, A is an acceptor monosaccharide, and P-R is a lipophosphoglycerate mimetic group. Members of the library have a glycosidic linkage between the anomeric carbon of D and the C2 carbon of A, and the D-A moiety is in turn covalently linked through the anomeric carbon of A to the P-R group. Members of the library exhibit their greatest structural diversity in terms of substitutions occurring at the C3 position of the A residue, substitutions at the C2 position of the D residue, and different P-R groups used in assembling the compounds. Members of the library are preferably synthesized by solid phase techniques involving stepwise coupling of the respective units to a support, functionalizing the A and/or D saccharides either before or after immobilizing them on the support, and cleaving the assembled compounds from the support.
