CYP450-Dependent Biotransformation of the Insecticide Fipronil into Fipronil Sulfone Can Mediate Fipronil-Induced Thyroid Disruption in Rats [PDF]
Toxicological Sciences, 2012 In rats, the widely used insecticide fipronil increases the clearance of thyroxine (T(4)). This effect is associated with a high plasma concentration of fipronil sulfone, the fipronil main metabolite in several species including rats and humans. In sheep, following fipronil treatment, fipronil sulfone plasma concentration and thyroid disruption are ...

Fipronil and fipronil sulfone in chicken: From in vitro experiments to in vivo PBK model predictions
Food and Chemical Toxicology, 2022 In 2017 a large-scale fipronil contamination in eggs occurred in several European countries. Fipronil and its metabolites have the potential to be transferred into the eggs of laying hens, thereby entering the human food chain. Here, first the metabolism of fipronil was measured in vitro using chicken liver S9.

Bench‐Stable Electrophilic Reagents for the Direct Di‐ and Trifluoroethylthiolation of Indoles
Advanced Synthesis &Catalysis, Volume 365, Issue 20, Page 3438-3443, October 24, 2023., 2023 Abstract Two saccharine‐based electrophilic reagents were developed for the direct introduction of SCH2CF3 and SCH2CF2H motifs via a C−S bond forming reaction. Their large‐scale preparation and reactivity performance has been carefully examined, enabling access to a series of indoles through open‐flask reactions.
