Toward the Synthesis of Pestalustaine A: Structural Revision and Formation of Original Strained Tricyclic Architectures

Angewandte Chemie, EarlyView.
Our synthetic endeavor toward the total synthesis of the reported unprecedented tricyclic skeleton of the sesquiterpene pestalustaine A allowed us to perform divergent cyclizations of a bicyclo[4.4.1]undec‐3‐ene into complex tricyclic architectures and to revise the structure of the natural product.

Adipose‐derived mesenchymal stem cell injection into the KI10 acupoint mitigates cartilage damage in KOA rats through PGE2‐mediated α7nAChR/NF‐κB pathway

Animal Models and Experimental Medicine, EarlyView.
In our research, KOA rat models were established and treated with ADSC injection into the KI10 acupoint. Pain relief, behavioral function, and joint structural improvements were systematically assessed using ethological tests, imaging, histopathological staining, transmission electron microscopy, and molecular analyses.

Photometallobiocatalytic Asymmetric Radical‐Mediated Cross‐Coupling of Organotrifluoroborate Salts and Pyridotriazoles

Angewandte Chemie, EarlyView.
An enantioselective photometallobiocatalytic cross‐coupling of pyridotriazoles and secondary alkyltrifluoroborate salts is developed. Cooperative catalysis using eosin B and an engineered protoglobin combines visible‐light‐mediated radical generation with enzymatic metal carbenoid activation, affording valuable N‐heterocyclic products in excellent ...

Natural Aging of Biomaterials in Ambient and Physiological Environments

Advanced NanoBiomed Research, EarlyView.
Biomaterials used in biomedical applications can change their physical properties over time, even under ambient and physiological conditions. This review highlights key studies on the natural aging of materials ranging from soft hydrogels to metals and ceramics, emphasizing how time‐dependent changes influence function and performance.

Remapping the Synthetic Landscape of α‐Tertiary Alkylamines via Dual‐Functional Catechol

Angewandte Chemie, EarlyView.
A three‐component assembly strategy has been developed for the modular synthesis of hindered α‐tertiary aliphatic amines from readily available precursors through unlocking the dual role of catechol. The practicality of this methodology has been demonstrated in over 90 examples, including compounds that are otherwise difficult to access, along with ...
