Abstract
The use of mass spectrometry for chiral recognition and quantification has attracted great interest owing to its speed, sensitivity, specificity, and tolerance. However, searching for chiral selectors in chiral analyses using mass spectrometry is still problematic. In this study, chiral drugs could be applied as references for the chiral recognition and enantiomeric quantification of valsartan and voriconazole. Two novel pairs of metal-bound diastereomeric complex ions were detected by mass spectrometry, namely, nickel (II)-bound dimeric ions [NiII (2R,5S-emtricitabine) (S-valsartan)-H]+ and [NiII (2R,5S-emtricitabine) (R-valsartan)-H]+ and copper (II)-bound dimeric ions [CuII (S,S,S-enalaprilat) (2S,3R-voriconazole)-H]+ and [CuII (S,S,S-enalaprilat) (2R,3S-voriconazole)-H]+ . The resulting diastereomers were successfully identified based on the relative intensities of their characteristic fragments using tandem mass spectrometry. The logarithm of the characteristic fragment ion abundance ratio exhibited a good linear relationship with the enantiomeric excess. Density functional theory calculations were also performed to elucidate the mechanism of the structural differences observed in the MS results. This established approach proves that chiral drugs can serve as ligands for the rapid recognition and quantitative analysis of other chiral drugs without a chiral chromatographic column or complex sample pretreatment.

Abstract
Acyl chlorides react rapidly with hydroxyl and amino groups in the absence of catalysts and therefore hold great promise for chiral mass spectrometry. Herein, a tandem mass spectrometry method based on derivatization with (-)-camphanic acid chloride as a simple chiral probe was developed for the highly sensitive detection and quantitation of levodropropizine and its enantiomer, namely, dextrodropropizine. The diastereomeric derivatization products were quantified based on the relative abundances of their fragment ions produced upon collision-induced dissociation in positive-ion mode. The reactive site was elucidated using nuclear magnetic resonance spectroscopy and two-dimensional total correlation spectroscopy, and the reaction mechanism was proved by stoichiometry studies. The degree of isomer recognition was investigated at different collision energies and determined as Rchiral ≈ 1.5. Thus, this study gives the way to the mass spectrometric identification and quantitation of levodropropizine and its enantiomer, and the developed method represents a new and practical technique for rapid and sensitive determination and quality control of enantiomers of chiral drugs.

Abstract
A facile mass spectrometric kinetic method for quantitative analysis of chiral compounds was developed by integrating mass spectrometry based on chemical derivatization and the spectral shape deformation quantitative theory. Chemical derivatization was employed to introduce diastereomeric environments to the chiral compounds of interest, resulting in different abundance distribution patterns of fragment ions of the derivatization products of enantiomers in mass spectrometry. The quantitative information of the chiral compounds of interest was extracted from complex mass spectral data by an advanced calibration model derived based on the spectral shape deformation quantitative theory. The performance of the proposed method was tested on the quantitative analysis of R-propranolol in propranolol tablets. Experimental results demonstrated that it could achieve accurate and precise concentration ratio predictions for R-propranolol with an average relative predictive error (ARPE) of about 4%, considerably better than the corresponding results of the mass spectrometric method based on chemical derivatization and the univariate ratiometric model (ARPE: about 12%). The limit of detection (LOD) and limit of quantification (LOQ) of the proposed method for the concentration ratio of R-propranolol were estimated to be 1.5% and 6.0%, respectively. The proposed method is complementary to the existing methods designed for the quantification of enantiomers such as the Cooks kinetic method.

Abstract
Rapid differentiation, characterization and quantification of isomers from complex mixtures by direct mass spectrometry (MS) remained an analytical challenge due to their similar or identical MS/MS spectra and matrix interferences. Here, we reported a novel online extraction-quadrupole time-of-flight tandem mass spectrometry (OLE-QTOF-MS/MS) system to rapid, efficient and sensitive analysis of interglycosidic linkage isomers (hesperidin and neohesperidin) in Citrus paradisi cv. Changshanhuyou (Changshanhuyou). OLE system packed with solid Changshanhuyou (0.02 mg) could be firstly used to online remove interferences with large polarities, and then online extract and enrich hesperidin and neohesperidin, which shows great potential to diminish the analysis time of sample pretreatment, as well as to reduce matrix effects and instrument consumption. Detailed fragmentation analysis found that, under positive ion mode, relative abundance of specific fragment ions m/z 449 to m/z 303 showed linear correlation to the mass content of hesperidin (0% to 100%) with good correlation coefficient (R2 = 0.9958). Utilizing this method, the mass ratio of hesperidin to neohesperidin in Changshanhuyou was relatively quantified as 3.7:96.3 with RSD at 2.9%. Finally, using internal standard method, the absolute quantitative analysis was performed with acceptable reproducibility (RSD 1.3 and 4.5% for intra- and inter-day variations) and recoveries (from 95.9% to 108.9%), acceptable limit of detection (0.33 ng). In general, OLE-QTOF-MS/MS represented a promising and practical method for simple, rapid and effective analysis of isomeric compounds in complex matrices.

Abstract
Here, a novel fluorescent chiral poly(ionic liquid) ( S)-PCIL-4 with nonconjugated backbone is designed and synthesized in the control of micelle through free-radical polymerization, whose fluorescence emission maximum is at λem,max = 430 nm. It is observed that polymers with spatially proximate units (phenyl group and pyridinium cation) have photoluminescence through spatial π-π and ion-π interaction. Then, ( S)-PCIL-4 can be served as a fluorescent turn off/on sensor for chiral recognition of phenylalaninol and tryptophan in the presence of Cu(II). For example, when ( S)-PCIL-4-Cu(II) is treated with ( R/ S)-phenylalaninol, it will exhibit different fluorescence responses. Values of the enantiomeric fluorescence difference ratio for phenylalaninol and tryptophan are 1.10 and 1.08, respectively. In brief, we believe that the approach opens up a possible pathway to prepare a variety of fluorescent polymers with nonconjugated backbone and proves to be desirable in further application.

Abstract
RATIONALE Quantitative analysis of cholesterol and its metabolic steroid hormones plays a vital role in diagnosing endocrine disorders and understanding disease progression, as well as in clinical medicine studies. Because of their extremely low abundance in body fluids, it remains a challenging task to develop a sensitive detection method. METHODS A hyphenated technique of dual ultrasonic-assisted dispersive liquid-liquid microextraction (dual-UADLLME) coupled with microwave-assisted derivatization (MAD) was proposed for cleansing, enrichment and sensitivity enhancement. 4'-Carboxy-substituted rosamine (CSR) was synthesized and used as derivatization reagent. An ultra-high performance liquid chromatography tandem mass spectrometry (UHPLC-MS/MS) method was developed for determination of cholesterol and its metabolic steroid hormones in the multiple reaction monitoring mode. RESULTS Parameters of dual-UADLLME, MAD and UHPLC-MS/MS were all optimized. Satisfactory linearity, recovery, repeatability, accuracy and precision, absence of matrix effect and extremely low limits of detection (LODs, 0.08-0.15 pg mL(-1) ) were achieved. CONCLUSIONS Through the combination of dual-UADLLME and MAD, a determination method for cholesterol and its metabolic steroid hormones in human plasma, serum and urine samples was developed and validated with high sensitivity, selectivity, accuracy and perfect matrix effect results.

Abstract
RATIONALE Miglitol (1) derived from 1-deoxynojirimycin is an iminosugar that is useful in the treatment of type 2 diabetes mellitus. Isomers (2, 3, 4) that differ at the C2 and C3 positions of hydroxyl groups from miglitol are impurities resulting from the synthesis of miglitol. The impurity profile of a drug substance is critical to its safety assessment and is important for monitoring the manufacturing process. Therefore, developing a fast and simple method that can rapidly identify the configuration of miglitol and its isomers (2, 3, 4) is necessary. METHODS Miglitol (1) and its isomers 2-4 were derivatized with benzoboroxole (o-hydroxymethyl phenylboronic acid) at room temperature, and the cyclic boronate esters of different configurations were generated. Protonated miglitol and its isomers 2-4, as well as their derivatives, were subjected to collision-induced dissociation (CID) experiments by using electrospray ionization tandem mass spectrometry (ESI-MS/MS). Elemental compositions of all the ions were verified by electrospray ion-trap time-of-flight mass spectrometry. RESULTS Fragmentation of the protonated miglitol and its isomers gave the same fragment ions at m/z 190 and m/z 146. Both their fragmentation behavior and abundances were similar. Whereas the CID mass spectra of the precursor ions (m/z 322) of cyclic boronate esters showed four characteristic fragment ions, m/z 214 ([M-C7 H8 O](-) ), m/z 196 ([M-C7 H8 O-H2 O](-) ), m/z 151 ([M-C8 H13 NO3 ](-) ), and m/z 133 ([M-C8 H15 NO4 ](-) ). The abundances of these fragments are different which are related to the stereostructure of miglitol and its isomers. CONCLUSIONS A facile method was established for the differentiation of the spatial configuration of miglitol and its isomers using the relative abundances of the fragment ions of boronate esters generated from in-situ reaction between analytes and benzoboroxole by ESI-MS/MS. This approach could be used to rapidly identify the stereoisomers and monitor the epimerization of miglitol and its isomers in chemical reactions and manufacturing processes.
