Chiral HPLC Separation of Phosphonothrixin and Phosphonate Derivatives and Electronic Circular Dichroism Characterization of the Isolated Enantiomers

ELECTROPHORESIS, EarlyView.
Natural compound phosphonothrixin's herbicidal activity resides exclusively in its (S)‐enantiomer, yet existing enantioselective syntheses are cumbersome, and direct chiral LC separation is hampered by the compound's high polarity, lack of aromatic groups, and metal chelation–induced peak tailing.

Antiseizure potency and neurotoxicity of the enantiomers of fenfluramine and norfenfluramine in rats and correlations with their concentrations in plasma and brain

Epilepsia, EarlyView.
Abstract Objective Based on the evidence that fenfluramine‐induced anorexia, weight loss, and cardiovascular toxicity are primarily mediated by the d‐enantiomers of fenfluramine and its metabolite norfenfluramine, we investigated pharmacokinetic/pharmacodynamic correlations for the active enantiomers of fenfluramine and norfenfluramine in the rat ...

Dose–response modelling uncovers compound‐specific inhibitory effects of host defence volatiles on mountain pine beetle fungal symbionts

Pest Management Science, EarlyView.
Host defence volatiles inhibit mountain pine beetle fungal symbionts in a compound‐ and enantiomer‐specific manner, with distinct dose–response profiles that reveal the multitarget chemical defences of beetle–fungi symbiotes. Abstract BACKGROUND The mountain pine beetle relies on symbiotic fungi to overcome host tree defences, yet these fungi must ...

Novel tetronamides derived from mucobromic acid: synthesis, structural elucidation, DFT calculations and phytotoxic activity

Pest Management Science, EarlyView.
The acyclic mucobromic acid, activated by (1S)‐(+)‐10‐camphorsulfonic acid, afforded the chiral compound 1b, precursor for aza‐Michael addition/elimination on the butenolide yielding tetronamides 2b‐7b. Their relative SRSR configuration was confirmed by the spectrometric methods, DFT calculation and statistical methods.

The continuing significance of chiral agrochemicals

Pest Management Science, Volume 81, Issue 4, Page 1697-1716, April 2025.
In the time frame 2018–2023, around 43% of the 35 chiral agrochemicals introduced to the market (herbicides, fungicides, insecticides, acaricides, and nematicides) contain one or more stereogenic centers in the molecule, and almost 69% of them have been marketed as racemic mixtures of enantiomers or stereoisomers.
