Multifunctional Nano Immunostimulant: Overcoming Immunosuppressive Microenvironment for Antitumor Immunotherapy

Advanced Science, EarlyView.
A multifunctional nano immunostimulant is first proposed for efficient tumor immunotherapy. The ER targeted ability, superior ROS production, efficient GSH consumption, coupled with the HIF suppression, jointly arouses ICD/ferroptosis pathways to realize efficient tumor immunotherapy.

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.

Copper(II)-Catalyzed Direct C3 Chalcogenylation of Indoles

Molecules
3-Chalcogenylindoles serve as crucial building blocks in organic synthesis and pharmaceutical chemistry. Herein, we describe a simple and general synthesis of 3-chalcogenylindoles through the direct C–H chalcogenation of indoles using N-selenophthalimide

Phocaeicola coprophilus‐Derived 6‐Methyluracil Attenuates Radiation‐Induced Intestinal Fibrosis by Suppressing the IDO1‐Kynurenine‐AHR Axis

Advanced Science, EarlyView.
IR‐induced dysbiosis depletes P. coprophilus and its metabolite 6‐methyluracil, leading to disinhibition of the IDO1‐Kyn‐AHR axis. This results in sustained fibroblast activation and collagen deposition, driving radiation induced intestinal fibrosis. ABSTRACT Therapeutic options for radiation‐induced intestinal fibrosis (RIF) remain limited. This study

Stable BF2 Boracycles as Versatile Reagents for Selective Ortho C–H Functionalization

Angewandte Chemie, EarlyView.
We report a robust, metal‐free and scalable synthesis of stable BF2 boracycles via directed ortho CH borylation, delivering isolable, shelf‐stable reagents without chromatographic purification. These BF2 boracycles exhibit unique and tunable reactivity, enabling highly selective ipso‐functionalization across a broad range of transformations.

Epidermal Cell Dynamics Regulates Rice Lamina Joint Morphogenesis and Leaf Angle Formation through OsZHD1 and OsZHD2 Regulation

Advanced Science, EarlyView.
The lamina joint determines leaf angle and plant architecture. Xu et al. establish a live‐imaging system for the rice lamina joint and reveal that asymmetric epidermal cell elongation and division between the lateral and medial edges drive leaf angle formation.
