Quantitative Mass Spectrometry‐Based Biodistribution of Monoclonal Antibodies: An Alternative to Radio‐Biodistribution

Advanced Science, EarlyView.
Monoclonal antibodies are powerful anticancer therapeutics targeting tumor‐associated antigens. Mass spectrometry enables precise and accurate quantification of mAbs in tumor plasma and healthy organs. Unlike ligand binding assay and radioactivity, mass spectrometry does not suffer from matrix effects and labelling artefacts while facilitating method ...

MVP Inhibits Influenza A Virus‐Induced Ferroptosis by Targeting IRF1 and Increasing FSP1 Activity

Advanced Science, EarlyView.
During IAV infection, MVP inhibits IRF1 polyubiquitination, thereby relieving IRF1‐mediated transcriptional inhibition of FSP1. Consequently, this leads to an upregulation of FSP1 expression, thereby reinforcing the inhibition of ferroptosis. In addition, the MVP can promote myristoylation and ubiquitination of FSP1, enabling its membrane localization ...

Hierarchical Channeled Graphitized Nanoarchitecture as a Diagnostic Platform for Maternal Fever Warning

Advanced Science, EarlyView.
This study presents a hierarchically channeled graphitized nanoarchitecture (HPGC‐Z67) as a novel nano‐diagnostic platform. It enables sensitive and efficient N‐glycan extraction from plasma, significantly reducing processing time and cost. The platform identifies pivotal N‐glycans to accurately differentiate between infectious and non‐infectious ...

A Reliable Strategy to Unravel the Structure and Composition of Semiconducting Conjugated Donor‐Acceptor Block Copolymers

Advanced Science, EarlyView.
This work proposes a reliable strategy to elucidate the structure and composition of conjugated donor‐acceptor block copolymers. The method, based on NMR analysis, allows to extract key structural information such as the number of heterojunctions (NoH) and the number of blocks (NoB) of the copolymers.

Phosphine Catalyzed Michael-Type Additions: The Synthesis of Glutamic Acid Derivatives from Arylidene-α-amino Esters

Molecules
The reaction of arylidene-α-amino esters with electrophilic alkenes to yield Michael-type addition compounds is optimized using several phosphines as organocatalysts. The transformation is very complicated due to the generation of several final compounds,
