AI Article Synopsis
- Cu-Cy nanoparticles are new sensitizers that can activate under various types of energy (UV light, X-rays, microwaves, and ultrasound) to produce reactive oxygen species, which are useful for treating cancer.
- The study investigates the effectiveness of Cu-Cy nanoparticles in killing both gram-positive and gram-negative bacteria, revealing that they are particularly effective against gram-positive bacteria like methicillin-resistant strains.
- The primary method of bacteria inactivation is through the production of singlet oxygen, suggesting that Cu-Cy nanoparticles could be promising agents for bacterial control despite their limited effect on gram-negative bacteria.
Article Abstract
Copper-cysteamine (Cu-Cy) nanoparticles (NPs) are a new type of sensitizers that can be activated by UV light, X-rays, microwaves and ultrasound to produce reactive oxygen species for cancer treatment. Here, for the first time, we explored Cu-Cy NPs for bacteria inactivation by treating gram-positive bacteria (methicillin-resistant and ) and gram-negative bacteria ( and ), respectively. The results show that Cu-Cy NPs are very effective in killing gram-positive bacteria but are quite limited in killing gram-negative bacteria yet. The major killing mechanism is cell damage by singlet oxygen and Cu-Cy NPs are potential agents for bacteria inactivation.

Copper-Cysteamine nanoparticles (Cu-Cy NPs) have emerged as promising radiosensitizers in cancer treatment. This study aims to investigate the combined therapeutic effect of these nanoparticles and cisplatin using a clinical linear accelerator to enhance the efficacy of chemoradiation therapy for cervical cancer. Following successful synthesis and characterization of Cu-Cy NPs, the cytotoxicity effect of these nanoparticles and cisplatin in various concentrations was evaluated on HeLa cancer cells, individually and in combination.

Article Synopsis
- Copper-cysteamine (Cu-Cy) acts as a new sensitizer that can be activated by various methods, including light and X-rays, to produce reactive oxygen species for cancer treatment.
- Recent studies investigated the effectiveness of Cu-Cy based X-ray induced photodynamic therapy (X-PDT) under clinical conditions using deep-seated tumor models, where it showed low toxicity and significant impact on cell proliferation and migration.
- MRI assessments confirmed that Cu-Cy X-PDT effectively inhibited tumor growth in animal models without obvious side effects, highlighting its potential for clinical applications in improving radiotherapy for deep tumors.
Combination of Disulfiram and Copper-Cysteamine Nanoparticles for an Enhanced Antitumor Effect on Esophageal Cancer.

Esophageal cancer (EC) is the sixth leading cause of cancer deaths worldwide with a low 5-year survival rate. More effective chemotherapeutic drugs, either new or repurposing ones, are urgently needed. Disulfiram (DSF) is a safe and public domain drug for alcohol addiction treatment and later shown to have anti-cancer capability, especially when administrated together with copper.

Herein, for the first time, we demonstrate that the combination of copper-cysteamine (Cu-Cy) nanoparticles (NPs) and potassium iodide (KI) can significantly inactivate both Gram-positive MRSA and Gram-negative E. coli. To uncover the mystery of the killing, the interaction of KI with Cu-Cy NPs was investigated systematically and the products from their interaction were identified.

Herein, for the first time, we report copper-cysteamine (Cu-Cy) nanoparticles having Cu instead of Cu as an efficient heterogeneous Fenton-like catalyst for highly selective cancer treatment. Initial measurements of Cu-Cy's hydroxyl radical generation ability show that it behaves as a Fenton-like reagent in the presence of HO (100 μM) at pH 7.4, and that its Fenton-like activity is dramatically enhanced under acidic conditions (pH 6.
