Discovery and Biosynthesis of the Novel Glycotetrapeptide Antibiotic Biffamycin A
Angewandte Chemie, EarlyView.Genetic de‐regulation of a silent biosynthetic pathway allowed isolation and characterisation of a novel glycopeptide antibiotic named biffamycin A, which harbours unprecedented 5‐chloro‐4‐methoxy tryptophan and 3R‐hydroxy(α‐D‐mannoysl)‐D‐lysine moieties and is bioactive against MRSA and VRSA.

One-Pot Conversion of Glycals to cis-1,2-Isopropylidene-α-glycosides
, 2016 Described is a general method for the conversion of glycals to the corresponding 1,2-cis-isopropylidene-α-glycosides. Epoxidation of glycals with dimethyldioxirane followed by ZnCl2-catalyzed addition of acetone converted a variety of protected glycals ...

Angewandte Chemie, EarlyView.We prepared five glycosylated liposomal nanoparticles (G‐LNPs) to investigate the role of glycosylation and protein corona in modulating the in vivo behavior of G‐LNPs. We show that IgG and complement C3 adsorption enhanced liposomal nanoparticle clearance, with IgG promoting subsequent C3 binding.

Advanced Science, EarlyView.Antibody–drug conjugates (ADCs) transform breast cancer therapy, yet resistance limits their durability. Emerging evidence reveals that ADC failure is not solely tumor‐intrinsic but shaped by dynamic tumor–microenvironment interactions that alter drug delivery, processing, and response.

Angewandte Chemie, EarlyView.We report plate‐based coupled assays to rapidly and quantitatively determine the activity and selectivity of mucin‐active carbohydrate sulfatases. This fluorogenic assay further enables inhibitor identification and allows determination of (sub‐)cellular location. ABSTRACT Sulfated glycans play a central role in human health and influence cell signaling,
