Efficient Preparation of Homogenous Antibody Conjugates via Glycosite‐Specific Transglycosylation Enabled by Readily Available Glycosyl Donors

open access: yesAngewandte Chemie, EarlyView.
A streamlined platform for glycosite‐specific antibody conjugation is enabled by LacNAc‐derived cyclic acetal donors, which can be prepared in only two steps and used directly in single‐enzyme Endo S2‐mediated transglycosylation. The platform supports the broad construction of homogeneous gsADCs and gsDACs, with donor 7 producing glycoengineered ...

Caylobolide B: Structure Revision, Total Synthesis, Biological Characterization, and Discovery of New Analogues

open access: yesAngewandte Chemie, EarlyView.
Marine polyhydroxylated macrolides’ drug discovery potential is limited by structural complexity and scarce material supply, hindering structure assignment, synthesis, and biological studies. Here, we present an integrated workflow that combines chemogenomic profiling, ultra‐high‐resolution NMR‐guided structural revision and stereochemical assignment ...

Suggesting a Way to Understand the Actual Potential of Anti-Alzheimer's Disease Drugs That Show Promise in Transgenic Mouse Models. [PDF]

open access: yes, 2017
One conundrum in Alzheimer's disease (AD) research using transgenic mouse models is the high amount of successful memory-enhancing drugs. By contrast, very few drugs and of limited efficacy are available for humans having this pathology.

Stereodivergent Synthesis of Three Contiguous Stereogenic Centers by Cu/Ir‐Catalyzed Borylallylation

open access: yesAngewandte Chemie, EarlyView.
An alkene borylallylation strategy enabled by cooperative Cu/Ir‐catalysis has been uncovered for accessing three contiguous stereogenic centres. This strategy is notable given the inherent challenges of constructing molecules with multiple stereocenters while maintaining high selectivity bearing diverse functional groups.

Side-by-side comparison of recombinant human glutathione peroxidases identifies overlapping substrate specificities for soluble hydroperoxides

open access: yesRedox Biology, 2023
Five out of eight human glutathione peroxidases (GPXs) are selenoproteins, representing proteins that contain selenium as part of the amino acid selenocysteine. The GPXs are important for reducing hydroperoxides in a glutathione-consuming manner and thus
