Perylenequinones in photodynamic therapy: cellular versus vascular response.

Journal of Environmental Pathology, Toxicology and Oncology, 2006
Photodynamic therapy (PDT) is a promising new modality in the treatment of cancers, which employs the interaction between a tumor-localizing photosensitizer and light of an appropriate wavelength to bring about molecular oxygen-induced cell death. We have investigated the efficacy of photosensitizers from the family perylenequinone, namely Hypericin ...

Deuterium isotope effect on 1H and 13C chemical shifts of intramolecularly hydrogen bonded perylenequinones

, 1997
The primary and secondary deuterium isotope effects on proton and carbon chemical shifts were measured for a number of natural pigments and their derivatives, which contain the perylenequinone system and present a phenol–quinone tautomerism, cercosporin ...
