Bimetallic Peroxide Nanocomposites‐Driven Redox Dyshomeostasis to Activate Sequential Cuproptosis and Pyroptosis for Amplified Tumor Immunotherapy

Advanced Science, EarlyView.
Hyaluronic acid‐modified bimetallic peroxide nanocomposites (MgO2‐CuO2@HA) are designed for synergistic tumor therapy. The nanocomposites release Mg2+, H2O2, and Cu2+ in tumor cells, induce cuproptosis via Cu+‐mediated protein aggregation, and activate pyroptosis through caspase‐1/gasdermin D pathways for inducing immunogenic cell death, collectively ...

Regioselective synthesis of 7,8-dihydroimidazo[5,1-c][1,2,4]triazine-3,6(2H,4H)-dione derivatives: A new drug-like heterocyclic scaffold

Beilstein Journal of Organic Chemistry, 2012
Dihydroimidazo[5,1-c][1,2,4]triazine-3,6(2H,4H)-dione derivatives were prepared by successive N3- and N1-alkylation of hydantoins, followed by regioselective thionation and subsequent cyclization under mild conditions.

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 ...

Investigation of Covalent Adaptable Networks (CANs) Based on Dynamic Acylhydrazone Bonds Featuring Shape‐Memory Ability

Journal of Applied Polymer Science, EarlyView.
Application of dynamic acylhydrazones to achieve CANs with shape‐memory properties. ABSTRACT Covalent adaptable networks (CANs) are based on reversible crosslinks, which are present within the polymer network structure. Due to these reversible moieties, CANs feature interesting properties/abilities such as self‐healing after damage, shape‐memory ...
