Linear solvation energy relationships in normal phase chromatography based on gradient separations
Journal of Chromatography A, 2017Coupling the modified Soczewiñski model and one gradient run, a gradient method was developed to build a linear solvation energy relationship (LSER) for normal phase chromatography. The gradient method was tested on dinitroanilinopropyl (DNAP) and silica columns with hexane/dichloromethane (DCM) mobile phases.

Quantum chemical descriptors for linear solvation energy relationships
Computers & Chemistry, 1995Linear solvation energy relationships (LSER) have been successfully used to correlate over 300 complex chemical and biochemical properties with small sets of descriptors related to fundamental characteristics of molecular structure and chemistry. This is a branch of the unnamed science (after Hansch) which is concerned with the intricate interactions ...

Microplastics (MPs) could act as vectors of organic pollutants such as per- and polyfluoroalkyl substances (PFAS). Therefore, understanding adsorptive interactions are essential steps towards unraveling the fate of PFAS in the natural waters where MPs are ubiquitous.

Solvatochromism and linear solvation energy relationship of the kinase inhibitor SKF86002
Spectrochimica Acta Part A: Molecular and Biomolecular Spectroscopy, 2017We studied the spectroscopic characteristics of SKF86002, an anti-inflammatory and tyrosine kinase inhibitor drug candidate. Two conformers SKF86002A and SKF86002B are separated by energy barriers of 19.68kJ·mol(-1) and 6.65kJ·mol(-1) due to H-bonds, and produce the three major UV-Vis absorption bands at 325nm, 260nm and 210nm in cyclohexane solutions.

Abstract A linear free energy relationship was found between ν max, the energy of the absorption maximum of the solvated electron in various solvents, and the alpha solvatochromic parameter which is a measure of the hydrogen bond donor ability of the solvent.

Modeling Drug‐Melanin Interaction With Theoretical Linear Solvation Energy Relationships
Pigment Cell Research, 1997The affinity of drugs and other xenobiotic agents for melanin is a well‐known phenomenon, often occurring with serious physiological consequences. For example, the interaction of anti‐psychotic drugs with neuromelanin may play a pivotal role in the induction of extrapyramidal movement disorders associated with the chronic administration of ...

Characterization of novel metallacarborane-based sorbents by linear solvation energy relationships
Journal of Chromatography A, 2014Two novel metallacarborane-based stationary phases for high performance liquid chromatography were synthesized and characterized utilizing linear solvation energy relationships concept. Interactions taking place between selected probes (45 analytes) and the stationary phases and the mobile phases consisting of a mixture of acetonitrile with buffer were

Abstract The separation of phospholipids was studied using supercritical fluid chromatography. The 2-ethylpyridine (2-EP), hybrid fluoro-phenyl (FP), C18, 2-picolylamine (2-PIC), 1-aminoanthracene (1-AA), DIOL and ethylene bridged hybrid (BEH) were used as stationary phases. Methanol with 0.1% formic acid was used as a co-solvent. For the first time,
