Profiling the Nematicidal Activity of Linear and Cyclic Compounds on the Pinewood Nematode

Chemistry Proceedings, 2021
The pinewood nematode (PWN), Bursaphelenchus xylophilus, has become one of the most damaging pests to forest health in Asia and Europe. In the screening for sustainable biopesticides, research has focused on highly active secondary metabolites.

The study of the optical activity of some S-derivatives 4-R-5-((((3-(pyridin-4-yl)-1H-1,2,4-triazole-5-yl)thio)methyl)-4H-1, 2,4-triazole-3-thiols

Aktualʹnì Pitannâ Farmacevtičnoï ì Medičnoï Nauki ta Praktiki, 2022
About half of the drugs currently produced are chiral compounds, and about 90 % of these compounds are sold as racemates, consisting of an equimolar mixture of two enantiomers.

Enantioselective effects of the fungicide metconazole on photosynthetic activity in Microcystis flos-aquae

Ecotoxicology and Environmental Safety, 2021
Enantiomers of chiral fungicides usually display different toxic effects on nontarget organisms in the surrounding environment, although there are rare reports on the enantioselective toxicity of metconazole (MEZ) to aquatic organisms, such as ...

Field-induced diastereomers for chiral separation [PDF]

, 2019
A novel approach for the state-specific enantiomeric enrichment and the spatial separation of enantiomers is presented. Our scheme utilizes techniques from strong-field laser physics, specifically an optical centrifuge in conjunction with a static ...

Putative ligand binding sites of two functionally characterized bark beetle odorant receptors

, 2021
Background: Bark beetles are major pests of conifer forests, and their behavior is primarily mediated via olfaction. Targeting the odorant receptors (ORs) may thus provide avenues towards improved pest control.

Enantiomers

, 2021
Only in exceptional cases, a pair of enantiomers do form a series of mixed crystals. The most well-known of the exceptions is the system laevorotatory carvoxime+dextrorotatory carvoxime; its properties are discussed in some detail. Also, attention is given to recent work on the polymorphism of optically active drugs.

Copper (II) Ions Induced Self-Disproportionation of Enantiomers in Capillary Electrophoresis for the Quantification of Atenolol Enantiomers

Molecules, 2023
Despite the fact that the self-disproportionation of enantiomers (SDE) has been found for several decades and has been widely used in crystallization, sublimation and chromatography for the purification or separation of nonracemic compounds, the ...

Kinetic resolution of racemates under chiral catalysis: connecting the dots [PDF]

, 2012
The current theory of the titled phenomenon is apparently based on an inconsistent use of concentration units, as employed in the derivation of the fundamental equations. Thus, manifestly, whilst the relation between extent of conversion and e.e.

Characterization of the conglomerate form of acetyl-dl-leucine by thermal analysis and solubility measurements [PDF]

, 2012
Starting from a mixture of enantiomers in solution, crystallization can generate different types of crystals. In order to determine which type of crystal is obtained in the case of acetylleucine, an active pharmaceutical ingredient (API), analytical ...
