Liquid Chromatographic Enantioseparation of Some Fluoroquinoline Drugs Using Several Polysaccharide-Based Chiral Stationary Phases [PDF]

Journal of Chromatographic Science, 2018
The enantioseparation of three fluoroquinoline antibacterial drugs, namely, flumequine, ofloxacin and lomefloxacin using high-performance liquid chromatography was optimized on seven polysaccharide-derived chiral stationary phases, namely, Chiralpak® IB, chiralpak® IA, Chiralpak® AD, Chiralcel® OJ, Chiralcel® OD, Chiralcel® OD-H and Chiralcel® OZ-3 and

Ions as Architects of DNA Nanostructures: Mechanisms, Simulations, and Technological Frontiers

Small Structures, Volume 7, Issue 3, March 2026.
Ions are not merely passive electrolytes but active regulators of DNA nanostructures. This review shows how ion valence, hydration, and specificity govern electrostatic screening, correlation, and confinement, enabling DNA origami, metallized DNA, nanopores, hydrogels, DNAzymes, molecular machines, and energy devices through integrated experimental and

Influence of mobile phase composition on the preparative separation of profens by chiral liquid chromatography [PDF]

, 2005
Liquid chiral chromatography of ketoprofen and flurbiprofen enantiomers is carried out using an amylose-based stationary phase. The mobile phases used for profens chiral separations are usually a hydrocarbon-alcohol combination, with high hydrocarbon ...

Designing a Green Chiral High‐Performance Liquid Chromatography Method: Proof‐of‐Concept with Crizotinib

Chemistry–Methods, Volume 6, Issue 2, February 2026.
A sustainable HPLC approach was developed for the enantioseparation of crizotinib using polysaccharide‐based chiral stationary phases under polar‐organic and reversed‐phase conditions. Experimental‐design optimization and greenness/whiteness assessment (AGREE, Eco‐Scale, Complex MoGAPI, AMGS, and RGB‐fast) identified an ethanol–water system as the most

On the effect of aqueous organic mobile phases on the enantioseparation of halogenated 4,4’-bipyridines using polysaccharide carbamate-based chiral columns

Journal of Chromatography Open
In the last decade, the contribution of halogen bond (HaB) in liquid phase enantioseparation of halogenated analytes was demonstrated by using polysaccharide-based chiral stationary phases (CSPs) and n-hexane-containing mixtures as mobile phases.
