TLDR
The antioxidant efficiency of some polyhydric phenols was determined kinetically and found to be catechol greather than pyrogallol greater than hydroquinone greater than resorcinol more than n-propyl gallate for the benzaldehyde photooxidation.About:

Photosensitization by drugs
TL;DR: UV irradiation of air-saturated methanol solutions of 20 drugs absorbing in the 300--400 nm region gave rise to oxygen uptake, as determined with a polarographic oxygen electrode.

Oxidation Photosensitized by Tetracyclines
Joy Anne Wiebe,Douglas E. Moore +1 more
TL;DR: Variation of tetracycline concentration, UV light intensity, and temperature showed the characteristics normally associated with a sensitized photo-oxygenation mechanism rather than a free-radical process, which has implications for the mechanism of in vivo photosensitivity reactions that occur when tetrACYclines are taken internally.
