Future 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 (

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

Pracaxi Oil as a Potential Inhibitor of Fat Bloom
Journal of the American Oil Chemists' Society, EarlyView.ABSTRACT Fat bloom is one of the major technological challenges faced by the chocolate industry, caused by the polymorphic transition from β2(V) to β1(VI) crystals in cocoa butter (CB). One strategy to slow down this polymorphic transition is the addition of lipids rich in very long chain fatty acids (VLCFA), such as behenic acid.

The Effect of Stereoisomerism on the 4D-QSAR Study of Some Dipeptidyl Boron Derivatives
, 2019 The electron conformational genetic algorithm (EC-GA) method had been employed by distinguishing between enantiomers for the first time as a 4D-QSAR approach to reveal the pharmacophore (Pha) and to predict the bioactivity of the dipeptidyl boron ...

Chemistry – A European Journal, EarlyView.A series of structurally diverse exoglycals was synthesized using a modified Julia‐olefination approach from sugar‐derived precursors. These glycosidase transition‐state mimics were further diversified via CuAAC chemistry to yield triazole‐conjugated analogues.

Chemistry – A European Journal, EarlyView.Males of the tropical frog Gephyromantis granulatus carry unique ethyl‐branched sesquiterpenoid macrolactones in their scent glands. Their structure elucidation was performed by GC/MS, leading to the proposed structures of the granolides. A flexible enantioselective synthesis confirmed the structures and allowed determination of their absolute ...
