Enantioselective Separation of 4,8-DHT and Phytotoxicity of the Enantiomers on Various Plant Species

Molecules, 2016
As a candidate for bioherbicide, 4,8-dihydroxy-1-tetralone (4,8-DHT) was isolated from Caryospora callicarpa epicarp and its two enantiomers, S-(+)-isosclerone and R-(−)-regiolone, were separated by chiral high-performance liquid chromatography (HPLC) on

The effect of amino acid enantiomers on activity of selected enzymes in soil

Acta Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 2011
This work was aimed to test the effect of selected amino acid enantiomers on activity of casein-protease and acid phosphomonoesterase in soil. Casein-protease was selected due to its key role in nitrogen mineralization and acid phosphomonoesterase due to

Separation of chiral particles in micro- or nanofluidic channels

, 2012
We propose a method to separate enantiomers in microfluidic or nanofluidic channels. It requires flow profiles which break chiral symmetry and have regions with high local shear. Such profiles can be generated in channels confined by walls with different

Theoretical Investigation on H2O2-Ng (He, Ne, Ar, Kr, Xe, and Rn) Complexes Suitable for Stereodynamics: Interactions and Thermal Chiral Rate Consequences

Frontiers in Chemistry, 2019
Although molecular collisions of noble gases (Ng) can be theoretically used to distinguish between the enantiomers of hydrogen peroxide - H2O2 (HP), little is known about the effects of HP-Ng interactions on the chiral rate. In this work, the chiral rate

The Binding of 3-O-Methylfluorescein Phosphate to the Catalytic Domain of the Human CDC25B Phosphatase: A Structural Investigation. [PDF]

Chembiochem
Structural studies on the complex that CDC25B C473S (CDC25B‐S) forms with the 3‐O‐methylfluorescein phosphate (3‐OMFP) reveal how the fluorogenic substrate binds CDC25B‐S, engaging key binding regions and inducing structural adjustments that stabilize the protein.

Reaction-noise induced homochirality

, 2006
Starting from the chemical master equation, we employ field theoretic techniques to derive Langevin-type equations that exactly describe the stochastic dynamics of the Frank chiral amplification model with spatial diffusion.

General Anesthetics: Aspects of Chirality, Pharmacodynamics, and Pharmacokinetics

Pharmaceuticals
The introduction of general anesthetics in the mid-19th century is considered one of the greatest contributions to medical practice. It was the first time that complicated surgical interventions became feasible, without putting an excessive strain on the

o‐Terphenyl‐Based Family of Conjugated Macrocycles: Selective Recognition of Phenylalanine in Water and Interaction With Insulin

Angewandte Chemie International Edition, EarlyView.
This study presents the synthesis and binding properties of a new family of o‐terphenyl‐based macrocycles, TP[n] (n = 2‐8). The trimer variant efficiently binds phenylalanine in water with a 10‐fold selectivity compared to other amino acids and aromatic neurotransmitters.

Dynamical Casimir-Polder interaction between a chiral molecule and a surface

, 2015
We develop a dynamical approach to study the Casimir-Polder force between a initially bare molecule and a magnetodielectric body at finite temperature.
