Abstract
A diallyl amine salt monomer bearing a β-CD substituent was cyclopolymerized for the first time. The reaction of 6-O-toluenesulfonyl-β-cyclodextrin [(C6H10O5)6-(C5H7)]-CH2OTs with diallylamine followed by protonation afforded the diallylamine salt monomer [(C6H10O5)6-(C5H7)]-CH2NH+(CH2CH=CH2)2 Cl-] (I). The cyclopolymerization of monomer I and its copolymerization with monomer [Me2N+(CH2CH=CH2)2 Cl-] (II), [-O2CCH2NH+(CH2CH=CH2)2] (III), [H2O3PCH2NH+(CH2CH=CH2)2 Cl-] (IV) or [HO2CCH2CH(CO2H)NH+(CH2CH=CH2)2 Cl-] (V) yielded a series of copolymers having residues of β-CD and glycine or methyl phosphonate or aspartic acid. Terpolymerization in the presence of SO2 afforded polymers with alternating placements of the SO2 units. The solution properties of the pH-responsive polyzwitterions, including their viscosity, were examined. The water-insoluble terpolymer I/V/SO2 with 20 mol% β-CD residues removed the organic micropollutant 2-naphthol from an aqueous system via host/guest complexation. This work paves the way for the possible synthesis of cross-linked polymers that can simultaneously remove organic micropollutants and toxic metal ions (by complexation with the chelating glycine, aspartic acid, and aminomethyl phosphonate ligands) from contaminated aqueous systems.

Abstract
''Chemistry beyond the molecule'' is the nickname for supramolecular chemistry. This branch of study is based on molecular recognition that is host-guest chemistry. A number of potential hosts have been defined and applied in scores of studies. Among all potential hosts, cyclodextrins occupy a high position due to their characteristic solubilisation capability and biocompatibility. In the present article we are revisiting the host-guest aspects of cyclodextrins from a physicochemical perspective. We present details of formation and applications of cyclodextrin nanoaggregates induced by guest molecules, the concerned thermodynamics behind the process and also the effect of concentration of the guest molecules on the morphology of the aggregates. This article reviews the topic mainly from the spectroscopic point of view.

Abstract
Today, approximately 60% of synthetic drugs are chiral and 88% of these chiral synthetic drugs are used therapeutically as racemates. However, for many racemic drugs, their stereospecific plasma pharmacokinetics in humans are not known due to the limitations of the analytical methods. Nowadays, liquid chromatography (LC)–tandem mass spectrometry (MS/MS) methods based on various chiral stationary phases (CSPs), with a high degree of specificity and sensitivity, have been widely used in enantioselective determination of chiral drugs and/or their metabolites in human plasma. The technologies and issues when coupling chiral chromatography with MS/MS detection in bioanalytical methods will be reviewed herein. The introduction and applications of various CPSs, including polysaccharide-, macrocyclic glycopeptide-, protein- and cyclodextrin-based phases, are described here. This review also includes a discussion of interface and matrix effects in enantioselective LC–MS/MS methods.

Abstract
A method for the determination of pindolol enantiomers in amniotic fluid and breast milk was developed, validated, and applied to the investigation of six pregnant women treated with rac-pindolol (10 mg/12 h). Biological samples were extracted with tert-methyl-butyl ether, and the pindolol enantiomers were resolved on a Chiralpak AD column. Amniotic fluid/plasma and milk/plasma concentrations ratios ranged from 0.4 to 4.5 and from 0.6 to 3.7, respectively, for (+)-R-pindolol and from 0.5 to 3.5 and from 1.1 to 2.8, respectively, for (-)-S-pindolol. Preliminary data suggest that amniotic fluid and breast milk are routes of fetal exposure to pindolol enantiomers.

Abstract
Determination of the chiral composition of drugs is nowadays a key step in order to determine purity, activity, bioavailability, biodegradation, etc., of pharmaceuticals. In this article, works published for the last 5 years on the analysis of chiral drugs by liquid separation techniques coupled with mass spectrometry are reviewed. Namely, chiral analysis of pharmaceuticals including, e.g., antiinflammatories, antihypertensives, relaxants, etc., by liquid chromatography-mass spectrometry and capillary electrophoresis-mass spectrometry are included. The importance and interest of the analysis of the enantiomers of the active compound and its metabolites in different biological fluids (plasma, urine, cerebrospinal fluid, etc.) are also discussed.

Abstract
Pindolol is a non-selective beta-adrenergic antagonist (beta-blocker) for the treatment of cardiovascular diseases such as hypertension and angina pectoris. It has one chiral center, and, therefore, two optical isomers. It was essential to develop an enantioselective assay to measure each enantiomer in human plasma. However, separation of enantiomers using chiral chromatography usually requires relatively long retention times. This can pose a problem for rapid turnaround of a large number of samples (i.e., clinical studies). In the present study, a simple and sensitive chiral liquid chromatography/electrospray ionization tandem mass spectrometry (LC/ESI-MS/MS) method was developed and validated for the determination of S-(-)- and R-(+)-pindolol in human plasma. To increase throughput, staggered sample injection was employed using a CTC Trio Valve system on a CTC HTS PAL autosampler. The method exhibited good intra- and inter-day accuracy and precision, and was linear over a dynamic range of 250 pg/mL to 250 ng/mL for each pindolol enantiomer. Intra- and inter-day accuracy ranged between 90.0-106% and 91.6-104% for both quality control (QC) samples of S-(-)- and R-(+)-pindolol, respectively. The respective intra- and inter-day precision ranged between 4.24-7.86% and 4.98-10.4%.

Abstract
A restricted access media-molecularly imprinted polymer (RAM-MIP) for propranolol (PRP) has been prepared for direct injection analysis of beta-blockers in biological fluids. First, the MIP for PRP was prepared using methacrylic acid and ethylene glycol dimethacrylate as the functional monomer and cross-linker, respectively, by a multi-step swelling and polymerization method. Next, a 1:1 mixture of glycerol monomethacrylate and glycerol dimethacrylate was used for hydrophilic surface modification, and added directly to the MIP for PRP after 4 h from the start of polymerization. Then further polymerization was carried out for 20 h. The obtained RAM-MIP for PRP showed excellent molecular recognition ability for PRP, good ones for alprenolol (ALP) and pindolol, and fair ones for other beta-blockers. The RAM-MIP was applied for direct injection analysis of ALP enantiomers in a rat plasma sample by a column-switching HPLC system using a beta-cyclodextrin phenylcarbamate-bonded silica column as the analytical column. The calibration graph, constructed from peak area versus each ALP enantiomer concentration, was linear with a correlation coefficient of > 0.999 over the concentration ranges of 12.5-250 ng ml(-1). The limit of quantitation was 12.5 ng ml(-1) with a 50 microl injection. This method could be applicable for the assay of ALP enantiomers at the therapeutic plasma levels, and have wide applicability for the assay of beta-blockers in biological fluids.

Abstract
We developed a determination method for human urinary 12-hydroxyeicosatetraenoic acid (12-HETE) using LC-MS-MS. This method, which includes simple extraction and detection in the SRM mode, allows precise and accurate determination of 12-HETE. There was a significant sex difference in urinary 12-HETE levels. Chiral analysis of 12-HETE using LC-MS-MS with column-switching technique revealed that the major enantiomer was 12(S)-HETE. Furthermore, the urinary level in patients with diabetes mellitus (DM) was analyzed. The present in vivo findings indicate that there could be difference in production of 12(S)-HETE between genders and 12(S)-HETE may play a role in the pathogenesis of DM.
