Abstract
Glycoproteins and glycopeptides are an interesting focus of research, because of
their potential use as therapeutic agents, since they are related to carbohydrate-carbohydrate,
carbohydrate-protein, and carbohydrate-lipid interactions, which are commonly involved in
biological processes. It has been established that natural glycoconjugates could be an important
source of templates for the design and development of molecules with therapeutic applications.
However, isolating large quantities of glycoconjugates from biological sources
with the required purity is extremely complex, because these molecules are found in heterogeneous
environments and in very low concentrations. As an alternative to solving this
problem, the chemical synthesis of glycoconjugates has been developed. In this context,
several methods for the synthesis of glycopeptides in solution and/or solid-phase have been
reported. In most of these methods, glycosylated amino acid derivatives are used as building
blocks for both solution and solid-phase synthesis. The synthetic viability of glycoconjugates is a critical parameter
for allowing their use as drugs to mitigate the impact of microbial resistance and/or cancer. However, the
chemical synthesis of glycoconjugates is a challenge, because these molecules possess multiple reaction sites and
have a very specific stereochemistry. Therefore, it is necessary to design and implement synthetic routes, which
may involve various protection schemes but can be stereoselective, environmentally friendly, and high-yielding.
This review focuses on glycopeptide synthesis by recapitulating the progress made over the last 15 years.

Multifaceted antibodies development against synthetic α-dystroglycan mucin glycopeptide as promising tools for dystroglycanopathies diagnostic. Glycoconj J 2019; 37:77-93. [PMID: 31823246 DOI: 10.1007/s10719-019-09893-z] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/17/2019] [Revised: 10/23/2019] [Accepted: 10/31/2019] [Indexed: 01/19/2023]
Abstract
Dystroglycanopathies are diseases characterized by progressive muscular degeneration and impairment of patient's quality of life. They are associated with altered glycosylation of the dystrophin-glycoprotein (DGC) complex components, such as α-dystroglycan (α-DG), fundamental in the structural and functional stability of the muscle fiber. The diagnosis of dystroglycanopathies is currently based on the observation of clinical manifestations, muscle biopsies and enzymatic measures, and the available monoclonal antibodies are not specific for the dystrophic hypoglycosylated muscle condition. Thus, modified α-DG mucins have been considered potential targets for the development of new diagnostic strategies toward these diseases. In this context, this work describes the synthesis of the hypoglycosylated α-DG mimetic glycopeptide NHAc-Gly-Pro-Thr-Val-Thr[αMan]-Ile-Arg-Gly-BSA (1) as a potential tool for the development of novel antibodies applicable to dystroglycanopathies diagnosis. Glycopeptide 1 was used for the development of polyclonal antibodies and recombinant monoclonal antibodies by Phage Display technology. Accordingly, polyclonal antibodies were reactive to glycopeptide 1, which enables the application of anti-glycopeptide 1 antibodies in immune reactive assays targeting hypoglycosylated α-DG. Regarding monoclonal antibodies, for the first time variable heavy (VH) and variable light (VL) immunoglobulin domains were selected by Phage Display, identified by NGS and described by in silico analysis. The best-characterized VH and VL domains were cloned, expressed in E. coli Shuffle T7 cells, and used to construct a single chain fragment variable that recognized the Glycopeptide 1 (GpαDG1 scFv). Molecular modelling of glycopeptide 1 and GpαDG1 scFv suggested that their interaction occurs through hydrogen bonds and hydrophobic contacts involving amino acids from scFv (I51, Y33, S229, Y235, and P233) and R8 and α-mannose from Glycopeptide 1.
