Organocatalytic C─O Bond Cleavage and Asymmetric Transformations via [1,3]‐Sigmatropic Rearrangement

Advanced Science, EarlyView.
A direct asymmetric strategy for fulfilling the functional group transfer by aryl ether cleavage and migration is developed, representing the first Brønsted base‐catalyzed asymmetric [1,3]‐sigmatropic rearrangement reaction. The resulting chiral benzofuran products generated through this strategy exhibit significant 3D‐dimensionality and demonstrate ...

A pH‐Sensitive Nanosized Covalent–Organic Polymer for Enhanced Tumor Photodynamic Immunotherapy by Hypoxia Relief and STAT3 Inhibition

Advanced Science, EarlyView.
The nanosized covalent organic polymer composed of photosensitizer porphyrin, pyruvate kinase inhibitor vitamin K3, and STAT3 inhibitor WP1066 is prepared for enhanced photodynamic immunotherapy by simultaneous hypoxia relief and STAT3 inhibition. Abstract Photodynamic therapy (PDT) is a promising cancer therapy modality by generating reactive oxygen ...

Nanofabricated Bacterial Cell Walls with Intrinsic Peroxidase‐Mimicking and Sonodynamic Activities for Cancer Combination Treatment

Advanced Science, EarlyView.
Bacterial cell walls (CWs) extracted from Porphyromonas gingivalis are nanofabricated to form the CW vesicles (CWV), which have intrinsic peroxidase‐mimicking and sonodynamic activities due to the presence of µ‐oxo bisheme and meanwhile retain a large amount of lipopolysaccharide.

Monitoring the Dynamics of Alzheimer's Disease Biomarkers and the APOE–Tau Axis via Human Cerebral Organoids with Immuno‐SERS

Advanced Science, EarlyView.
Noninvasive and sensitive detection of tau protein dynamics across developmental stages and APOE genotypes remain a challenge in Alzheimer's disease (AD) research. This study reveals the dynamics of tau secretion in label‐free manner using surface‐enhanced Raman spectroscopy (SERS) and human cerebral organoids (hCOs). This study provides novel insights

Impact of Virus‐Mediated Modifications in Bacterial Communities on the Accumulation of Soil Organic Carbon

Advanced Science, EarlyView.
This study illustrates the impact of viruses on carbon cycling in soils with different availabilities of carbon. In conditions of low carbon availability, viruses adopt a lysogenic lifestyle, integrate into the host genomes and facilitate the degradation of carbon.
