Synthesis and Biological Evaluation of Well‐Defined M6P(n)‐Modified Glycopeptides for Targeted Protein Degradation

Chemistry – A European Journal, EarlyView.
A synthetic methodology has been developed to prepare multifunctional M6P and M6Pn ligands of different valency. The glycopeptides were conjugated to cetuximab and then examined to mediate cellular uptake of fluorescently labeled EGFRvIII. Only cetuximab modified by glycopeptides having 3 or 6 M6P or M6Pn residues demonstrated greater uptake.

Hybrid Macrocyclic Peptides — Synthetic Strategies to Diversify and Cyclize Peptide Libraries in Phage Display Selections

Chemistry – A European Journal, EarlyView.
Hybrid macrocyclic peptides unite genetically encoded peptide libraries with the structural complexity of synthetic small molecules. This Review critically analyzes phage‐compatible cyclization and diversification chemistries, highlights emerging opportunities beyond traditional cysteine‐based approaches, and outlines how future advances may enable the

Prevalence of Non-Toxigenic Clostridioides difficile in Diarrhoea Patients and Their Clinical Characteristics

Antibiotics, 2023
Non-toxigenic Clostridioides difficile (NTCD) has been shown to decrease the risk of recurrent C. difficile infection (CDI) in patients following metronidazole or vancomycin treatment for CDI. Limited data on the prevalence of NTCD strains in symptomatic

Stereoselective Synthesis of β‐C‐glycosides From Exoglycals Through Radical C─C Bond Formation

Chemistry – A European Journal, EarlyView.
We describe herein a convenient strategy for the preparation of β‐C‐glycosides via the addition of radical species onto exoglycals. This method is efficient, general and achieved in mild conditions starting from xanthates derivatives and using triethylborane as initiator and 4‐tert‐butylcatechol as hydrogen atom source. This hydroalkylation reaction is

Synthetic glycopeptides and glycoproteins with applications in biological research

Beilstein Journal of Organic Chemistry, 2012
Over the past few years, synthetic methods for the preparation of complex glycopeptides have been drastically improved. The need for homogenous glycopeptides and glycoproteins with defined chemical structures to study diverse biological phenomena further

Glycopeptide Antibiotic Resistance Genes in Glycopeptide-Producing Organisms [PDF]

Antimicrobial Agents and Chemotherapy, 1998
ABSTRACT The mechanism of high-level resistance to vancomycin in enterococci consists of the synthesis of peptidoglycan terminating in d -alanyl- d -lactate instead of the usual d -alanyl- d -alanine.

The utility of serum markers in the conservative management of placenta accreta spectrum (PAS) by leaving the placenta in situ in women with high‐grade PAS

International Journal of Gynecology &Obstetrics, EarlyView.
Abstract Objective To investigate the association between serum markers and successful conservative management of patients with placenta accreta spectrum (PAS). Methods This was a retrospective case–control study where patients with high‐grade PAS between 2011 and 2025 undergoing conservative leaving the placenta in situ were included.

Solid-Phase Synthesis and Evaluation of Glycopeptide Fragments from Rat Epididymal Cysteine-Rich Secretory Protein-1 (Crisp-1) ‡

Molecules, 2010
Three 18-residue peptides with the sequence Glp-Asp-Thr-Thr-Asp-Glu-Trp-Asp-Arg-Asp-Leu-Glu-Asn-Leu-Ser-Thr-Thr-Lys, taken from the N-terminus of the rat epididymal cysteine-rich secretory protein (Crisp-1) that is important in the fertilization process,

Maternal and infant gut microbiome

iMeta, EarlyView.
The maternal–infant continuum involves critical windows of host–microbiota co‐adaptation. Preconception, maternal and paternal microbiomes modulate immunity and reproduction. During pregnancy, a gut–placenta axis emerges, where microbial metabolites influence fetal growth or contribute to complications like gestational diabetes mellitus (GDM ...
