Multimodal AI‐Driven Identification of Dehydrocostus Lactone as a Potent Renal Fibrosis Attenuator Targeting IQGAP1

Advanced Science, EarlyView.
Renal fibrosis, a hallmark of CKD, lacks effective treatments. Herein, we developed a multimodal AI model (TCM‐SPred) to identify anti‐fibrotic agents and found that dehydrocostus lactone (DCL) targets IQGAP1 to inhibit Wnt signaling, blocking the interaction between IQGAP1 and CCT3, demonstrating potent anti‐fibrotic activity in vitro and in vivo ...

Development and Structural Characterization of UTE‐156, a Covalent Inhibitor of the VCP/p97 AAA+ ATPase

Advanced Science, EarlyView.
The AAA+ ATPase Valosin‐containing protein (VCP/p97) regulates protein homeostasis by unfolding ubiquitinated substrates. Here, we describe UTE‐156, a novel irreversible covalent inhibitor that modifies Cys522 in the D2 ATPase motor domain. Although its pharmacochemical limitations preclude immediate therapeutic use, UTE‐156 serves as a valuable ...

Hepatocyte BDNF Acts as a Novel Immune Checkpoint to Restrain TLR4‐Mediated Acute Hepatitis

Advanced Science, EarlyView.
This study identifies hepatocyte‐derived BDNF as an endogenous TLR4 antagonist that alleviates acute hepatitis. BDNF is downregulated in hepatocytes via REST‐mediated transcriptional repression during ALI/ALF. Mechanistically, BDNF binds to TLR4 on macrophages to suppress inflammation.

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 ...

Covalent Protein Inhibitors via Tyrosine and Tryptophan Conjugation with Cyclic Imine Mannich Electrophiles

Angewandte Chemie, EarlyView.
Targeted covalent inhibitors (TCI) containing cyclic imine warheads react with tyrosine and tryptophan residues via the Mannich reaction. These cyclic imine warheads show comparable reaction kinetics to cysteine‐reactive electrophiles commonly used in TCIs.

Hydrophilic Janus Micelles From an ABC Triblock Copolymer

Angewandte Chemie, EarlyView.
An amphiphilic triblock copolymer with poly(ethylene glycol) (PEG) and poly(N‐vinylpyrrolidone) (PVP) coronas self‐assembles into spherical micelles with Janus‐type surface segregation in water. Cryo‐TEM, enabled by selective PVP labeling, and 1H‐NOESY NMR reveal phase separation.

Designing Scalable Mechano‐Virucidal Nanostructured Acrylic Surfaces for Enhanced Viral Inactivation

Advanced Science, EarlyView.
Can a surface be designed to physically break viruses? This study explores how nanoscale geometry—specifically the spacing of tiny pillars—can determine whether viruses remain intact or rupture. Using flexible acrylic and a scalable fabrication process, the authors develop nanopillared, transparent surfaces that show strong antiviral activity without ...

Harnessing Methyltransferase‐Guided Targeting for Sequence‐Specific Proximity Labeling of DNA

Angewandte Chemie, EarlyView.
A novel methyltransferase‐mediated approach leveraging rationally designed S‐adenosyl‐L‐methionine (SAM) analogues was developed to achieve sequence‐specific DNA labeling but in proximity to the natural transfer site, addressing key limitations of previously established methods, including ligand instability and methylation‐sensitive labeling.

Alquilação seletiva na posição N1 de timina e uracil em sistema de Mitsunobu/Selective alkylation at the N1 position of thymine and uracil in the Mitsunobu system

Orbital: The Electronic Journal of Chemistry, 2010
Selectivity of alkylation at the N1 position in pyrimidines (thymine and uracil) was achieved by the application of N3-benzoyl thymine and N3-benzoyl uracil as substrates, where the N3 atom was temporarily protected, exposing the N1 atom as the ...
