A One Step Synthesis of the Ciclamycin Trisaccharide
-
of outstanding interest, In this work differential activation of two 2-deoxy glycosyl donors as substituted anomeric phenyl sulfoxides and silyl masking of one of two hydroxy acceptors has allowed, for the first time, a completely selective one-pot synthesis of a trisaccharide with two different donors. It remains to be seen whether the approach can find general application in oligosaccharide synthesis.

A Strategy for the Solid-phase Synthesis of Oligosaccharides
-
of special interest, The first successful solid-phase synthesis of a more complex oligosaccharide was achieved by Danishefsky et al.. This elegant work uses the anomeric oxidation of glycals into oxiranes, which are activated on the solid phase for stereoselective glycosylation reactions. A silyl linkage to the non-reducing end allows selective release of the oligosaccharide at the end of the synthesis. The complete stereoselectivity of the glycosylation is still a matter of debate [21].

Only highly selective β-glycosylation reactions were used.

x-containing Hexasaccharide Found on 0-linked Glycoproteins
-
of outstanding interest, This incredibly fast synthesis of a sialyl Lewis-X containing hexasaccharide uses a lipophilic spacer for the solid phase extraction of glycosylation products in combination with virtually quantitative glycosylations using glycosyltransferases. This method will have considerable potential as the transferases become more available.

Silyl Protection in the Solid-phase Synthesis of N-Linked Glycopeptides. Preparation of Glycosylated Fluorogenic Substrates for Subtilisins
-
of special interest, in press, In this work a method was developed for an efficient two-step preparation affording completely protected large building blocks for N-linked glycopeptide assembly. By synthesis of glycosylated internally quenched fluorogenic peptide substrates, the authors provide the first evidence that the glycosylation may confer specificity on the proteolytic cleavage of glycosylated peptides and proteins.

Synthetic Glycosylation of Peptides Using Unprotected Saccharide Glycosylamines
-
of special interest, Both this and [38•] describe a convergent approach to the synthesis of N-linked glycopeptides which allow even large complex structures isolated from nature to be incorporated into glycopeptides on the solid phase by selective activation of an aspartic acid residue. Partial suppression of side reactions such as aspartimide formation was achieved.

Total Synthesis of the Carbohydrate-protein Linkage Region Common to Several Mammalian Proteoglycans
-
of special interest, A tetrasaccharide trichloroacetimidate from the proteoglycan core was prepared as a shelf-stable building block. It was used for glycosylation of a dipeptide and the resulting glycopeptide was used in fragment condensations to construct impressive model compounds of proteoglycans.

A New strategy for Fast Solid-Phase Synthesis of O-Glycopeptiden via 2-Azido-glycopeptide
-
of special interest, [in German], A much improved and more direct procedure for the preparation of mucin glycopeptides was described. The 2-azido-2-deoxygalactose obtained by azidonitration was directly incorporated into an activated amino acid to form a building block for solid-phase synthesis. The azide was quantitatively converted into the desired acetamide after peptide assembly.

Synthesis of Glycosylated Peptide Templates Containing 6′-O-Phosphorylated Mannose Disaccharides and Their Binding to the Mannose-6-phosphate Receptor
-
of outstanding interest, This work defines the minimum requirement for the successful synthesis of high-affinity glycopeptide ligands for receptors in which several domains are involved in the interaction with a complex carbohydrate ligand. The authors demonstrated that the mannose 6-phosphate receptor interacts directly with two Man6P-(1→2)-Man disaccharides and the rest of the oligosaccharide can be replaced with peptide templates. The approach may have considerable potential for defining the structure, function and distribution of mammal lectins.

Chemical and Enzymatic Synthesis of Multivalent Sialoglycopeptides
-
of special interest, The use of enzymes to glycosylate several identical glycosyl acceptors has allowed the efficient synthesis of a number of multivalent sialoglycopeptides as possible inhibitors of the influenza virus. This approach is a general method for obtaining glycopeptides containing several identical complex oligosaccharides. Unfortunately, the prepared compounds did not show the expected activity.

Solid-phase Chemical-enzymatic Synthesis of Glycopeptides and Oligosaccharides

of outstanding interest, The first successful solid-phase enzymatic oligosaccharide synthesis was reported. Two enzymatic glycosylations of a small glycopeptide were performed on a silica-gel surface, and in this way the previous problems of inaccessibility of the interior of polystyrene resins were overcome to yield 55–65% in enzyme-catalyzed reactions.

A PEGA Resin for Use in Solid Phase Chemical/Enzymatic Synthesis of Glycopeptides
-
of outstanding interest, The design of a new type of highly swelling and flexible PEG-based polymer in the form of a beaded resin has allowed quantitative solid phase glycosylatioin of a glycopeptide using glycosyltransferase. The resin, which is a versatile alternative to the silica gel approach mentioned above, allows full access of transferases of up to 5O kDa into the interior and may be modified to accommodate even larger proteins.

De Novo Design and Synthesis of Somatostatin Non-peptide Peptidomimetics Utilizing β-d-Glucose as a Novel Scaffolding
-
of outstanding interest, This outstanding research describes the synthesis of a non-peptide peptidomimetic in which a glucopyranose scaffold mimics the cyclic part of the peptide backbone of somatostatin. The interacting side chains of the peptide are simulated by the attachment of similar functional groups to the hydroxy groups of the glucopyranose. This approach may well be a general way of mimicking small-peptide hormones.

Synthesis of Glycosyl-enkephalin Analogues which Rapidly Cross the Blood-Brain Barrier to Produce Analgesia in Mice An Entirely New Class of ‘Designer Drugs’
-
of special interest, Enkephalin glycopeptides were synthesized and found to rapidly cross the blood-brain barrier. This new principle of glycosylation of peptides in order to introduce glycans as markers for recognition and active transport across membranes may have great potential for drug delivery. Furthermore, the glycosylation can increase the lifetime of the active peptide by providing protection against proteolylic degradation.
