Enantioselectivity of chiral compounds is receiving growing concern. Lactofen, a chiral herbicide widely used in field crops and vegetables to control broadleaf weeds, is still sold as racemate. In this work, the herbicidal activity and metabolism behavior of lactofen were investigated on an enantiomeric level.

Lactofen – Electrochemical Sensing and Interaction with dsDNA
Electroanalysis, 2018AbstractThe electrochemical reduction of lactofen (LCT) at the glassy carbon (GCE) and silver amalgam film electrode (AMFE) is investigatedin detail by the means of square wave voltammetry (SWV), square wave stripping voltammetry (SWSV) and cyclic voltammetry. The influence of various factors such as supporting electrolyte composition and SW parameters

Effects of Salinity on Herbicide Lactofen Residues in Soil
Water, Air, & Soil Pollution, 2017Soil salinization is an increasing problem in agricultural soils on a worldwide scale. To assess the effects of salinity on the fate of herbicide lactofen in soil, laboratory degradation experiments were performed using soil with and without additional salinity.

Stereoselective toxicity and metabolism of lactofen in primary hepatocytes from rat.
Chirality, 2013ABSTRACTThe stereoselective metabolism of lactofen in primary rat hepatocytes was studied using a chiral high‐performance liquid chromatographic (HPLC) method. Rac‐lactofen and its two enantiomers, S‐(+)‐ and R‐(−)‐lactofen, as well as two of its major metabolites, acifluorfen, S‐(+)‐ and R‐(−)‐desethyl lactofen, were used as substrates,.

Potential defense-related prenylated isoflavones in lactofen-induced soybean.
Phytochemistry, 2011An integrated LC-MS and NMR metabolomic study was conducted to investigate metabolites whose formation was induced by lactofen (1), a soybean (Glycine max L.) disease resistance-inducing herbicide. First, LC-MS analyses of control and lactofen (1)-induced soybean extracts were performed.

The diphenyl ether herbicide lactofen is commonly used to control broadleaf weeds. Once released into the environment, this herbicide is subject to microbial reactions. This study describes the biotransformation of lactofen by Brevundimonas sp. LY-2 isolated from enrichment cultures inoculated with soil sample. This strain degraded about 80% of 50 mg L(

Chiral herbicides consist of two or more enantiomers, which usually differ in their biological properties and behave enantioselectively in biochemical process. Scant studies have been published in the past decades to characterize the enantiomers of herbicide lactofen.

Enantioselective toxicity of lactofen and its metabolites in Scenedesmus obliquus
Algal Research, 2015Abstract In this study, the acute toxicity of lactofen and its two metabolites desethyl lactofen and acifluorfen was determined in the aquatic algae Scenedesmus obliquus . After exposure for 96 h, the EC 50 values for S-(+)-, rac-, and R-(−)-lactofen were 0.896, 0.784, and 0.649 μg/L, respectively; the EC 50 values for S-(+)-, rac-, and R ...
