Domino Polymerization for the Synthesis of Reductively Degradable Poly(disulfide)s With Arbitrary Side‐Chain Structures

Angewandte Chemie, EarlyView.
We developed a novel domino polymerization to synthesize reductively degradable poly(disulfide)s with tunable side chains. A novel monomer bearing thiolactone and pyridyl disulfide groups reacts with various amines, enabling continuous ring‐opening and disulfide exchange.

The ITGB2‐COPS3‐SOX2 Axis and SOX2 Liquid‐Liquid Phase Separation: Dual Mechanisms Governing Osteosarcoma Stemness

Advanced Science, EarlyView.
Osteosarcoma stemness is driven by the ITGB2‐COPS3‐SOX2 signaling axis. This study reveals that nuclear COPS3 stabilizes SOX2, which in turn undergoes liquid‐liquid phase separation to promote stemness. Based on this mechanism, a novel COPS3 inhibitor, Z‐5891, was developed, effectively suppressing tumor growth and stemness in vivo, offering a ...

Trinuclear Heptamethine Dyes for Shortwave Infrared In Vivo Imaging

Angewandte Chemie, EarlyView.
The reactivity of cyclopentenyl‐bridged polymethine dyes is leveraged to synthesize shortwave infrared (SWIR)‐emissive di‐ and trinuclear polymethine dyes. Chromenylium‐ and flavylium‐based trinuclear dyes demonstrate increased nucleophilic stability, minimal aggregation in micelle formulations, and notable lymph node accumulation.

Semi‐Reduction of Allenes to Access Deuterated Allylic Isotopomers, Isotopologs and Enantioisotopomers

Angewandte Chemie, EarlyView.
Modular and Precise Deuteration: The synthesis of molecules precisely deuterated at allylic, vinylic or both positions remains a challenging task. This work discloses a modular semi‐reductive deuteration that enables the synthesis of various isotopologs including precisely labeled d1‐, d2‐, d3‐, d5‐, and d7‐products.

Synthesis of New Azo Compounds Based on N-(4-Hydroxypheneyl)maleimide and N-(4-Methylpheneyl)maleimide

Molecules, 2010
Maleic anhydride was reacted with p-aminophenol and p-toluidine in the presence of di-phosphorus pentoxide (P2O5) as a catalyst to produce two compounds: N-(4-hydroxy-phenyl)maleimide (I) and N-(4-methylphenyl)maleimide (II). The new azo compounds I(a-c)

Aggregation‐Induced Resonance Energy Transfer in Polymer Dots to Boost Electrochemiluminescence Performance for Bioimaging of Glycan on Cells

Advanced Science, EarlyView.
This study pioneers an aggregation‐induced resonance energy transfer mechanism by synergistically integrating aggregation‐induced emission (AIE), resonance energy transfer (RET), and thermally activated delayed fluorescence (TADF) within co‐reactant conjugated polymers to develop self‐enhanced ECL emitters, which achieves an ECL efficiency up to 92.6 ...
