Eur J Med Chem 2024; 276:116633. [PMID: 38968785 DOI: 10.1016/j.ejmech.2024.116633] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/05/2024] [Revised: 06/25/2024] [Accepted: 06/25/2024] [Indexed: 07/07/2024]
Abstract
Influenza remains a global public health threat, and the development of new antivirals is crucial to combat emerging drug-resistant influenza strains. In this study, we report the synthesis and evaluation of a sialyl lactosyl (TS)-bovine serum albumin (BSA) conjugate as a potential multivalent inhibitor of the influenza virus. The key trisaccharide component, TS, was efficiently prepared via a chemoenzymatic approach, followed by conjugation to dibenzocyclooctyne-modified BSA via a strain-promoted azide-alkyne cycloaddition reaction. Biophysical and biochemical assays, including surface plasmon resonance, isothermal titration calorimetry, hemagglutination inhibition, and neuraminidase inhibition, demonstrated the strong binding affinity of TS-BSA to the hemagglutinin (HA) and neuraminidase (NA) proteins of the influenza virus as well as intact virion particles. Notably, TS-BSA exhibited potent inhibitory activity against viral entry and release, preventing cytopathic effects in cell culture. This multivalent presentation strategy highlights the potential of glycocluster-based antivirals for combating influenza and other drug-resistant viral strains.

[PMID: 38342079 DOI: 10.1016/j.bmc.2024.117615] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/27/2023] [Revised: 01/25/2024] [Accepted: 01/26/2024] [Indexed: 02/13/2024]
Abstract
sTF (sialyl-Thomsen-Friedenreich) is a type of tumor-associated carbohydrate antigens (TACAs) and is highly expressed in various human malignancies. To validate if sTF could be a valuable molecular target for future cancer vaccine development, in this work the sTF antigen was prepared by adopting a strategy combining chemical and enzymatic methods, and then was covalently conjugated to a carrier protein, CRM197. The preliminary immunological evaluation, performed on BALB/c mice, revealed that the sTF-CRM197 conjugate elicited high titers of specific IgG antibodies. FACS experiments showed that the antisera induced by sTF-CRM197 conjugate could specifically recognize and bind to sTF-positive cancer cells T-47D. Furthermore, the conjugate mediated effective and specific antibody-mediated complement-dependent cytotoxicity (CDC).

Harvey DJ. Analysis of carbohydrates and glycoconjugates by matrix-assisted laser desorption/ionization mass spectrometry: An update for 2019-2020. MASS SPECTROMETRY REVIEWS 2022:e21806. [PMID: 36468275 DOI: 10.1002/mas.21806] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Indexed: 06/17/2023]
Abstract
This review is the tenth update of the original article published in 1999 on the application of matrix-assisted laser desorption/ionization (MALDI) mass spectrometry to the analysis of carbohydrates and glycoconjugates and brings coverage of the literature to the end of 2020. Also included are papers that describe methods appropriate to analysis by MALDI, such as sample preparation techniques, even though the ionization method is not MALDI. The review is basically divided into three sections: (1) general aspects such as theory of the MALDI process, matrices, derivatization, MALDI imaging, fragmentation, quantification and the use of arrays. (2) Applications to various structural types such as oligo- and polysaccharides, glycoproteins, glycolipids, glycosides and biopharmaceuticals, and (3) other areas such as medicine, industrial processes and glycan synthesis where MALDI is extensively used. Much of the material relating to applications is presented in tabular form. The reported work shows increasing use of incorporation of new techniques such as ion mobility and the enormous impact that MALDI imaging is having. MALDI, although invented nearly 40 years ago is still an ideal technique for carbohydrate analysis and advancements in the technique and range of applications show little sign of diminishing.

Abstract
A highly efficient chemoenzymatic method for synthesizing ganglioside GM3 and lyso-GM3 was reported here. Enzymatic extension of the chemically synthesized lactosyl sphingosine using efficient one-pot multienzyme (OPME) reaction allowed glycosylation to be carried out in aqueous solutions realizing the greening of reactions. Ganglioside GM3 was synthesized through 10 steps with a total yield of 22%. Lyso-GM3 was very useful for kinds of derivatization. The anti-proliferation activity studies demonstrated that these compounds 14-16 with sphingosine exhibited more potency than the corresponding lyso-GM3 with ceramide. All ganglioside GM3 and lyso-GM3 can effectively inhibit the migration of melanoma B16-F10 cells. These chemoenzymaticlly synthesized GM3 and lyso-GM3 exhibited antitumor activities, which can provide valuable sights to search new antitumor agents for cancer therapy.

Abstract
In this study, we designed and developed a novel asialoglycoprotein receptor (ASGPR)-targeted PEGylated paclitaxel (PTX) nanoliposome for hepatocellular carcinoma (HCC). N-acetylgalactosamine with α configuration (Tn) was synthesized and used as the active targeting ligand. Notably, Tn modified nanoliposomes loaded with PTX (Tn-Lipo-PTX) showed a narrow distribution (PDI = 0.18-0.20) with 74 ± 0.36 nm of average sizes. Tn-Lipo-PTX has a high encapsulation efficiency of more than 93.0% and 13% of drug loading (DL). Compared with no targeted Con-Lipo-PTX, Tn-Lipo-PTX showed lower and sustained release characteristic in PBS in vitro. Tn targeting ASGPR was confirmed by HepG-2 cells uptake experiment by fluorescence microscopy analysis. Tn-Lipo-PTX accumulated in HepG-2 cells and this process was inhibited by adding Tn ligand, supporting receptor-mediated endocytosis mechanism. MTT assays was implemented in four cell lines. Tn-Lipo-PTX exhibited superior inhibition against ASGPR on over-expressing HepG-2 (IC50 = 1.93 nM). The cell cycle experiments showed that Tn-Lipo-PTX could efficiently increase the percentage of cells arrest in the G2/M phase. Through western blotting analysis, the β-tubulin and cyclin B1 expression in the Tn-Lipo-PTX group were significantly higher compared with other groups and the CDK1 was down-regulated compared with PTX group, which indicated that targeting liposome delivery system could not only change periodic proteins expression, but also improve the killing effect of PTX on hepatocarcinoma cell. Tn-installed PEGylated nanoliposomes have a great potential for targeted cancer chemotherapy.

Recent progress in synthesis of carbohydrates with sugar nucleotide-dependent glycosyltransferases. Curr Opin Chem Biol 2020; 61:81-95.

Abstract
Sugar nucleotide-dependent glycosyltransferases (GTs) are key enzymes that catalyze the formation of glycosidic bonds in nature. They have been increasingly applied in the synthesis of complex carbohydrates and glycoconjugates with or without in situ generation of sugar nucleotides. Human GTs are becoming more accessible and new bacterial GTs have been identified and characterized. An increasing number of crystal structures elucidated for GTs from mammalian and bacterial sources facilitate structure-based design of mutants as improved catalysts for synthesis. Automated platforms have also been developed for chemoenzymatic synthesis of carbohydrates. Recent progress in applying sugar nucleotide-dependent GTs in enzymatic and chemoenzymatic synthesis of mammalian glycans and glycoconjugates, bacterial surface glycans, and glycosylated natural products from bacteria and plants are reviewed.
