Glutathione-dependent cytotoxicity of the chloroacetanilide herbicides alachlor, metolachlor, and propachlor in rat and human hepatoma-derived cultured cells.

Cell Biol. Toxicol. 15(5) , 325-32, (1999)

Alachlor, metolachlor, and propachlor are widely used chloroacetanilide herbicides. Their cytotoxicity in rat (Fa32) and human (Hep G2) hepatoma-derived cells was investigated, in connection with thei...

Kinetics and mechanism of propachlor reductive transformation through nucleophilic substitution by dithionite

Chemosphere 85(9) , 1438-43, (2011)

Highlights ► The reductive dechlorination of propachlor was efficiently achieved by dithionite. ► The transformation of propachlor initiated by dithionite follows second-order kinetics. ► Dechlorinati...

Characterization of glutathione conjugates of chloroacetanilide pesticides using ultra-performance liquid chromatography/quadrupole time-of-flight mass spectrometry and liquid chromatography/ion trap mass spectrometry.

Rapid Commun. Mass Spectrom. 21(24) , 4017-22, (2007)

Glutathione S-transferases (GSTs) isolated from maize were used to catalyze the conjugation of glutathione (GSH) with chloroacetanilide herbicides, producing stable conjugates that were structurally c...
