日期:——
On the basis of the de novo and salvage biosynthetic pathways, diverse dTDP-activated sugarnucleotides, which are important but difficult to access, were successfully prepared on a large scale from readily available starting materials. This high-yielding synthetic strategy avoids the need for complicated purification procedures.

The present invention provides combinatorial methods for rapidly generating a diverse library of glycorandomized structures, comprising incubating one or more aglycons and a pool of NDP-sugars in the presence of a glycosyltransferase. The glycosyltransferase may be one that is associated with or involved in production of natural secondary metabolites, or one which is putatively associated with or involved in production of natural secondary metabolites. The glycosyltransferase may show significant flexibility with respect to its NDP-sugar donors and/or its aglycons. NDP-sugar donors may be commercially available, or may be produced by utilizing mutant or wild type nucleotidyltransferases significant flexibility with respect to their substrates.
