Impacts of structural photomodification on the toxicity of environmental contaminants: anthracene photooxidation products.
The toxicity of polycyclic aromatic hydrocarbons (PHAs) is known to be enhanced by light via photosensitization reactions (production of active oxygen) and photomodification of the chemicals (e.g., oxidation) to more toxic compounds. Anthracene (ANT) toxicity in particular has been found to increase dramatically following photomodification. The objective of this study was to identify the photoo...
متن کاملPhotooxidation by Pteridines'
Suinizary. A nunibl)er of pteridfines were examined( for activity in promotinig photop)hosphorylation in broken spinach chlioroplasts anid in stimlulating cvtochrome c photooxidation ill sonicated chloroplasts. Correlation was fouind between activities for the 2 reactions. Photophosphorylation promoted by pteridines was inhibited by DCMU and by anaerobic conditiolns. It is concluded that pterid...
متن کاملPhotooxidation of cytochrome P450-BM3.
High-valent iron-oxo species are thought to be intermediates in the catalytic cycles of oxygenases and peroxidases. An attractive route to these iron-oxo intermediates involves laser flash-quench oxidation of ferric hemes, as demonstrated by our work on the ferryl (compound II) and ferryl porphyrin radical cation (compound I) intermediates of horseradish peroxidase. Extension of this work to in...

متن کاملRetarded photooxidation of cyamemazine in biomimetic microenvironments.
Cyamemazine (CMZ) is a neuroleptic drug that mediates cutaneous phototoxicity in humans. Here, the photobehavior of CMZ has been examined within α1 -acid glycoproteins, β- and γ-cyclodextrins and SDS micelles. In all these microenvironments, CMZ emission was enhanced and blue-shifted, and its lifetime was longer. Irradiation of the entrapped drug at 355 nm, under air; led to the N,S-dioxide. Wi...
