Incorporating Molecule's Stereisomerism within the Machine Learning Framework

open access: yes, 2014
International audienceAn important field of chemoinformatics consists in the prediction of molecule's properties, and within this field, graph kernels constitute a powerful framework thanks to their ability to combine a natural encoding of molecules by ...

Stereoisomerism of Molecular Multipropellers. 1. Static Stereochemistry of Bis- and Tris-triaryl Systems

open access: yes, 2016
The static stereoisomerism of bis- and tris-triaryl systems has been analyzed by a systematic stereochemical analysis, and the resulting theoretical predictions have been experimentally confirmed by using reversed-phase HPLC and ESR and 1H NMR ...

Anti-atherosclerotic activity of catechins depends on their stereoisomerism

open access: yes, 2015
In terms of stereochemistry, catechins are divided into two groups: (-) epi forms (2R, 3R) and (-) forms (2S, 3R). Most of the catechins present in green tea are (-) epi forms (2R, 3R).

Stereoisomerism‐controlled Packing in Ladder‐type Indacenodithieno[3,2‐b]thiophene Crystals

open access: yesAggregate
Stereochemistry is a potent way to direct the molecular packing in condensed phases. Here, we synthesized the enantiopure, racemic, and achiral isomers of p‐type small molecule, that is, indacenodithieno[3,2‐b]thiophene, to understand the impact of ...

A new bonded silica based on an amino acid derivative as a TLC stationary phase to solve nitrophenol structural isomerism and ibuprofen stereoisomerism

open access: yesFuture Journal of Pharmaceutical Sciences, 2020
Background Many amino acids and their derivatives have been used previously as chiral selectors in thin layer chromatography. Herein, we reported the synthesis, characterization, and chromatographic evaluation of a new modified stationary phase based on (

MAGNETIC SUSCEPTIBILITY AND OPTICAL ROTATORY POWERS OF p-HYDROXY-α-NAPHTHYLIMINOCAMPHOR.

open access: yes, 1940
The magnetic susceptibility and rotatory powers of p-hydroxy-α-naphthylimino­camphor have been described. The two forms of the compound have different suscep­tibilities which suggest that the differences are not due to the size of the aggregate of the ...
