CSF‐Compartmentalized Antibody Glycoprofiles in NMDAR Encephalitis Associate with Etiology and Functional Recovery

Annals of Neurology, EarlyView.
Objective To characterize Fc‐glycosylation profiles in patients with anti‐N‐methyl‐D‐aspartate receptor encephalitis (NMDARe) and assess their association with antibody compartmentalization (cerebrospinal fluid [CSF] vs serum), disease triggers (viral, tumor‐related or idiopathic), and 1‐year outcomes.

Photoinduced Selective Construction of Densely Functionalized Spirocyclic Ethers With Carbyne Equivalents

Angewandte Chemie, EarlyView.
A reactivity programmed cascade between carbyne equivalents and allylic benzoates was developed that sequentially orchestrates all three reactivity modes of carbyne equivalents, enabling the rapid installation of three σ‐bonds at a single carbon center and providing efficient, scalable access to structurally diverse spirocyclic ethers. ABSTRACT Carbyne

Fast Ultra‐Selective 1H‐15N 1D NMR Spectroscopy Unlocks Atom‐Resolved Dynamics of Low‐Complexity Protein Regions

Angewandte Chemie, EarlyView.
NMR 15N spin‐relaxation rates are a primary source of information for deciphering protein conformational dynamics, but they require unreasonable experimental times when their 1H‐15N 2D spectra are highly congested. We propose an ultra‐selective method, SNIPER, that greatly accelerates data collection of individual residues. This allows characterization

Yb2‐Tb Upconversion in a Hetero‐Trimetallic Molecular Lanthanide Complex

Angewandte Chemie, EarlyView.
Lanthanides are at the forefront of photon upconversion in molecular systems; however, the chemical nature of the lanthanides makes site‐specific coordination chemistry difficult to achieve. Here, we employ kinetically stabile building blocks to achieve hetero‐trimetallic 4f complexes with complete site‐specific chemical control.

From Covalent Traps to Fluorescent Beacons: The Expanding Arsenal of Chemical Probes for Studying Ubiquitin and Ubiquitin‐Like Proteins

Angewandte Chemie, EarlyView.
A large variety of chemistry‐based ubiquitin probes have been developed. ABSTRACT Ubiquitin (Ub) and ubiquitin‐like proteins (Ubls) orchestrate diverse cellular processes through reversible post‐translational modification of target proteins. Their conjugation is governed by a cascade of E1 activating, E2 conjugating, and E3 ligating enzymes, while ...
