Airborne nano-TiO 2 particles: an innate or environmentally-induced toxicity ? [PDF]

, 2017
Titanium oxide (TiO2) is a known photocatalyst, able to produce reactive oxygen species (ROS) when exposed to UV light. TiO2 phototoxicity has been abundantly demonstrated in aqueous solutions.

Excited-State Dynamics of the Thiopurine Prodrug 6-Thioguanine: Can N9-Glycosylation Affect Its Phototoxic Activity?

Molecules, 2017
6-Thioguanine, an immunosuppressant and anticancer prodrug, has been shown to induce DNA damage and cell death following exposure to UVA radiation. Its metabolite, 6-thioguanosine, plays a major role in the prodrug’s overall photoreactivity.
