H2S‐Amplified “Three‐in‐One” Antibacterial Strategy for Periodontitis Treatment Using a Photosensitive Pillararene‐Embedded COF/MOF Hybrid

Advanced Science, EarlyView.
The integration of ROS‐generating systems with H2S depletion strategies effectively overcomes the limitations imposed by endogenous antioxidant defenses on ROS‐based antimicrobial therapies. In this study, the Cu‐MOF is incorporated into pillararene‐embedded COF, achieving a “three‐in‐one” antimicrobial effect that markedly alleviated periodontal ...

Supramolecular Assembly of Stepped‐Persistent ROS Nanogenerator for Sustained Tumor Immunotherapy

Advanced Science, EarlyView.
ROS catalytic systems often fail to achieve both effective tumor elimination and persistent immune activation due to their monotonous ROS production profiles. A stepped‐persistent ROS nanogenerator was developed by supramolecularly assembling multiple ROS generation modules within a nanofiber structure to simultaneously extend ROS generation duration ...

DNA‐mimic for Specific Surface Functionalization of Zr‐MOFs for Bacterial Targeting

Angewandte Chemie, EarlyView.
We introduce phosphotyrosine‐modified PNA as a superior, single‐step post‐synthesis surface coating for PCN‐222. The DNA mimic allows for controlled post‐functionalization with single‐stranded DNA for the attachment of protein moieties for bacterial targeting. ABSTRACT Nanosized metal–organic frameworks (MOFs) are versatile platforms used in biomedical

Heat Shock Protein 90: From Molecular Chaperone Function to Therapeutic Targeting in Malignancies

Advanced Science, EarlyView.
In this review, an integrated conceptual framework linking HSP90's molecular chaperone functions to its pathological roles in cancer is proposed. HSP90 serves as a central node that integrates oncogenic signaling, buffers proteotoxic stress, maintains cancer stem cell plasticity, and shapes tumor‐immune interactions, all of which converge to drive ...

Perilipin‐2‐Anchored Lipid Droplet‐Targeting Phototheranostics

Angewandte Chemie, EarlyView.
This study reports two NIR theranostic dyes, C‐BDP‐OH and C‐BDP‐OMe. C‐BDP‐OMe targets lipid droplets via a dual‐anchoring mechanism with PLIN2, enabling wash‐free tumor imaging. With 62.6% photothermal conversion efficiency, it achieves tumor ablation by downregulating PLIN2, disrupting LD‐mitochondria crosstalk, and triggering apoptosis and ...

Hypericin-Mediated Photodynamic Inactivation Against the Plant Pathogen Clavibacter michiganensis: Preventative Seed Decontamination Enhanced by Potassium Iodide

Microorganisms
Clavibacter michiganensis causes significant crop losses in tomatoes, and the disease may be transferred by plant seeds. This study evaluates the efficacy of Photodynamic Inactivation (PDI) with a water-soluble hypericin derivative, developed as a ...

Clinical Photodynamic Therapy and Photodynamic Detection

Biomedical Optics, 1999
In the present communication, we present results of the preclinical/clinical development of the hexyl ester of 5 aminolevulinic acid as a precursor of protoporphyrin IX for photodetection and phototherapy of early cancer in the bladder and other organs.

A Deep‐Red‐Absorbing Osmium(II) Complex as a Photosensitizer for Photodynamic Therapy Inducing Immunogenic Cell Death

Angewandte Chemie, EarlyView.
A deep‐red‐excited osmium(II) photosensitizer (Os2) induces immunogenic cell death (ICD) under 740 nm irradiation and triggers robust anti‐tumor immune responses both in vitro and in vivo. ABSTRACT Immunogenic cell death (ICD), which converts tumor cells into their own vaccine, plays a pivotal role in the development of novel anticancer therapies. Here,

Successful treatment of 7,12-dimethylbenz(a)anthracene-induced hamster buccal pouch precancerous lesions by topical 5-aminolevulinic acid-mediated photodynamic therapy

, 2014
Background: Our previous studies found that topical 5-aminolevulinic acid (ALA)-mediated photodynamic therapy (ALA-PDT) with a light dose of 100J/cm(2) is very effective for human oral precancerous lesions. Methods: In this study, 20 7,12-dimethylbenz(a)
