Elucidation of Fipronil Photodegradation Pathways

Journal of Agricultural and Food Chemistry, 2000
The phenylpyrazole insecticide fipronil (I) photolyzes to its desthio product (II) in aqueous solution. However, the necessity of an intervening oxidation to a sulfone intermediate (III) has not been resolved, and the photodegradation products of II have not been identified.

Analytical Method for Fipronil and Fipronil Sulfone in Livestock Products Using LC-MS/MS

Food Hygiene and Safety Science (Shokuhin Eiseigaku Zasshi), 2020
A rapid and sensitive method for the simultaneous determination of fipronil and fipronil sulfone (metabolite B) in livestock products was developed. The analytes were extracted from samples with acidic acetonitrile. The crude extracts were subjected to clean-up step using neutral alumina cartridge column.

Recent advances on the influence of fipronil on insect behavior.

Current Opinion in Insect Science
Fipronil, a pesticide widely used to control agricultural and household insect pests, blocks insect GABAA and glutamate (GluCl) ionotropic receptors, resulting in uncontrolled hyperexcitation and paralysis that eventually leads to death.

Multiple Mechanisms Confer Fipronil Resistance in the German Cockroach: Enhanced Detoxification and Rdl Mutation

Journal of medical entomology, 2022
Populations of Blattella germanica (L.) (German cockroach) have been documented worldwide to be resistant to a wide variety of insecticides with multiple modes of action. The phenylpyrazole insecticide fipronil has been used extensively to control German

P-coumaric acid ameliorates fipronil induced liver injury in mice through attenuation of structural changes, oxidative stress and inflammation.

Pesticide Biochemistry and Physiology, 2021
Fipronil is a broad-spectrum phenylpyrazole insecticide and has been used effectively in the agriculture. Due to its widespread use and bioaccumulation in the environment, it possesses significant threat to human and animals. P-coumaric acid is a natural

Synthesis of fipronil sulfide, an active metabolite, from the parent insecticide fipronil

Tetrahedron Letters, 2001
Abstract A convenient procedure for the synthesis of fipronil sulfide, one of several active metabolites identified from the insecticide fipronil, has been developed. Reduction of fipronil with trifluoroacetic anhydride–sodium iodide in acetone, followed by flash chromatography afforded fipronil sulfide in 60% yield and >99.9 percent purity.
