Interleukin-15Rα-Sushi-Fc Fusion Protein Co-Hitchhikes Interleukin-15 and Pheophorbide A for Cancer Photoimmunotherapy

Pharmaceutics
Background: Interleukin-15 (IL-15) stimulates the proliferation of natural killer cells or T cells, which, in combination with photodynamic therapy (PDT), has emerged as an effective strategy for cancer photoimmunotherapy.

Inactivation of Mitochondrial Electron Transport by Photosensitization of a Pheophorbide a Derivative

Molecules and Cells, 2004
We examined the damage to mitochondrial electron transport caused by photosensitization of a pheophorbide a derivative, DH-I-180-3, shown recently to induce necrosis of lung carcinoma cells with low dark toxicity. Confocal microscopy showed that DH-I-180-3 co-localized with dihydrorhodamine-123 suggesting that it mainly accumulates in mitochondria. The

Pheophorbide a effect upon dark- and photooxidation of olefins

Тонкие химические технологии, 2006
Peculiarities of pheophorbide’s a behavior in conditions of photosensitized and dark oxidation of natural olefin limonene have been analyzed. It is shown that phaeophorbide a is the photosensitizer of limonene oxidation, but it does not act upon its dark

Photochemical Redox Reactions of Catecholamines: Detection of Cyclized Oxidation Products and Boronate Esters

Photochem
Our recent work has focused on red light-mediated photoreduction of p-benzoquinones and both o-, and p-naphthoquinones using methylene blue and the chlorophyll metabolite, pheophorbide A as photosensitizers.

Liposomes-based co-delivery of pheophorbide a and gold nanoparticles for thermo-photodynamic therapy purpose on lung cancer spheroids

Results in Chemistry
Co-delivery of drugs in nanotechnology is a novel area of cancer therapy. In this study, we designed and synthesized a new nanocomplex (Lipo@AuNPs@PPBa) as photosensitizer (PS) from gold nanoparticles (AuNPs) and pheophorbide a (PPBa) for photodynamic ...

Photochemical Redox Cycling of Naphthoquinones Mediated by Methylene Blue and Pheophorbide A

Molecules
The photoreduction of plastoquinone, a para-benzoquinone, by chlorophyll initiates photosynthesis in chloroplasts. The direct photoreduction of biologically relevant quinones by dietary chlorophyll metabolites has been reported and may influence health ...

Mechanistic insights into apoptosis induced by green synthesized liposomal gold nanoparticles enhancing photodynamic therapy in triple-negative breast cancer

Results in Chemistry
Breast cancer still presents a major challenge in oncology, even with treatment advances. Its complexity is attributed to high mortality, late-stage diagnosis, and the development of resistance to conventional therapies such as surgery, chemotherapy ...
