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.

How Van der Waals Interactions Influence the Absorption Spectra of Pheophorbide a Complexes: A Mixed Quantum-Classical Study

, 2015
The computation of dispersive site energy shifts due to van der Waals interaction (London dispersion forces) was combined with mixed quantum-classical methodology to calculate the linear optical absorption spectra of large pheophorbide a (Pheo ...

Mixed Quantum Classical Simulations of Electronic Excitation Energy Transfer and Related Optical Spectra: Supramolecular Pheophorbide-a Complexes in Solution

, 2009
Photoinduced electronic excitation energy transfer in chromophore complexes is studied by utilizing a mixed quantum classical methodology. In order to describe the electronic excitations a Frenkel–exciton model is used and treated quantum mechanically ...

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.

Conjugated PDT drug. Phptosensitizing activity and tissue distribution of PEGylated pheophorbide a

, 2010
Pheophorbide a (Pba) has been pegylated to methoxypolyethylene glycol (mPE G-Pba) to produce a soluble photosensitizer that exhibits a higher tissue distribution than free Pba.

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 ...

Light-Harvesting Nanorods Based on Pheophorbide-Appending Cellulose

, 2016
In contrast to the success in artificial DNA- and peptide-based nanostructures, the ability of polysaccharides to self-assemble into one-, two-, and three-dimensional nanostructures are limited.
