Anal Chim Acta 2024; 1318:342960. [PMID: 39067929 DOI: 10.1016/j.aca.2024.342960] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/25/2024] [Revised: 06/09/2024] [Accepted: 07/08/2024] [Indexed: 07/30/2024]
Abstract
BACKGROUND Enantiodiscrimination of chiral drugs is critical for understanding physiological phenomena and ensuring medical safety. Although enantiomers of these drugs share identical physicochemical properties, they exhibit significant differences in pharmacodynamic, pharmacokinetic, and toxicological properties due to the differences in their three-dimensional shapes. Therefore, the development of effective methods for chiral recognition is of great significance and has been a hot topic in chemo/biological studies. RESULTS In this study, we designed a recognition receptor comprising a α-hemolysin (α-HL) nanopore and sulfobutyl ether-β-cyclodextrin (SBEβCD) for identifying the enantiomers of the antidepressant duloxetine at the single-molecule level. Chiral molecules were discriminated based on the different current blockages within the recognition receptor. The results indicated a strong interaction between R-duloxetine and the recognition receptor. By combining the experimental data and molecular docking results, we explored the recognition mechanism of the designed nanopore recognition receptor for chiral drug molecules. It was found that hydrophobic and electrostatic interactions play key roles in chiral recognition. Additionally, by comparing the binding kinetics of enantiomers to cyclodextrins in confined nanospace and bulk solution, we found that enantiomeric identification was better facilitated in the confined nanospace. Finally, the enantiomeric excess (ee) of the enantiomeric duloxetine mixture was measured using this recognized receptor. SIGNIFICANCE This strategy has the advantages of low cost, high sensitivity, and no need for additional derivative modifications, providing a new perspective on the development of chiral recognition sensors with excellent enantioselectivity in drug design, pharmaceuticals, and biological applications.

Abstract
OBJECTIVE During the COVID-19 pandemic, quarantine and staying at home is advised. The social relationship between people has become deficient, and human social isolation (SI) has become the consequence of this situation. It was shown that SI has made changes in hippocampal neuroplasticity, which will lead to poor cognitive function and behavioural abnormalities. There is a connection between SI, learning, and memory impairments. In addition, anxiety-like behaviour and increased aggressive mood in long-term isolation have been revealed during the COVID-19 outbreak. METHODS Term searches was done in Google Scholar, Scopus, ScienceDirect, Web of Science and PubMed databases as well as hand searching in key resource journals from 1979 to 2020. RESULTS Studies have shown that some drug administrations may positively affect or even prevent social isolation consequences in animal models. These drug treatments have included opioid drugs, anti-depressants, Antioxidants, and herbal medications. In addition to drug interventions, there are non-drug treatments that include an enriched environment, regular exercise, and music. CONCLUSION This manuscript aims to review improved cognitive impairments induced by SI during COVID-19.

Abstract
Duloxetine (DLX) is a widely used antidepressant drug belonging to the class of selective serotonin and norepinephrine reuptake inhibitors (SNRIs); its efficacy has been demonstrated in the treatment of not only major depressive disorders but also diabetic neuropathic pain, generalized anxiety disorder, fibromyalgia or stress urinary incontinence. It is a chiral substance and is used in therapy in the form of the enantiopure S-DLX, which is twice as active as R-DLX. Several methods have been published for the achiral and chiral determination of DLX in pharmaceuticals, biological materials and environmental samples, the majority using liquid chromatography and capillary electrophoresis coupled with different detection techniques (UV detection, fluorescence, mass spectrometry). The aim of the current review is to provide a systematic survey of the analytical techniques used for the determination of DLX from different matrices.

Abstract
Background:
Duloxetine (DL) is a selective serotonin and norepinephrine reuptake inhibitor.
The drug is used in the treatment of major depression, anxiety, pain related to diabetic peripheral neuropathy
and stress urinary incontinence.
</P><P>
Objective: This study described, for the first time, the development and validation of a highly selective
and sensitive microemulsion liquid chromatography-fluorescence (MELC-FL) method with low environmental
pollution and without extraction steps for the simultaneous quantification of DL, and its two
main metabolites; 5-hydroxy-6-methoxy duloxetine (5-HDL) and 4-hydroxy duloxetine glucuronide (4-
HDLG) in plasma.
Methods:
The studied analytes and methyl paraben (an internal standard) were detected using excitation
and emission wavelengths of 280 and 340 nm, respectively. The analysis was performed on Water
Symmetry C18 analytical column (100 Å, 150 mm x 3.9 mm, 5 µm) by directly injecting the plasma
after appropriate dilution with microemulsion mobile phase. Total analytical run time was 4 min.
Results:
The MELC-FL method was statistically validated according to the FDA guidelines for bioanalytical
methods for linearity, accuracy, precision, specificity, robustness, and stability. Linear calibration
plots were achieved in the ranges of 25-1200 ng/mL for DL and 50-1500 ng/mL for 5-HDL and 4-
HDLG (r2 ≥ 0.997) in rat plasma. The intra- and inter- assay precisions and accuracy were acceptable.
The overall recoveries of DL and its two main metabolites from rat plasma were between 97.12% and
103.12% with an RSD value between 0.34% and 4.57%.
Conclusion:
The present study supports the possible use of the microemulsion mobile phase in LC as a
“greener ” mobile phase. The developed method offered an advantage in the form of direct analysis of
biological samples after appropriate dilution with eco-friendly microemulsion mobile phase, which
decreased the possibility of sample loss during analysis. The developed assay was successfully applied
in a pharmacokinetic study and it established the applicability of the method for the determination of
concentration-time profiles of DL and its two main metabolites in rat plasma after systemic administration.

Abstract
Postmortem blood samples may not accurately reflect antemortem drug concentrations, as the levels of some drugs increase due to postmortem redistribution (PMR). The brain has been suggested as an alternative sampling site. The anatomically secluded site of the brain limits redistribution and prolongs the detection window, thereby enabling sampling from deceased individuals where blood is no longer suitable for analysis. We report concentrations in brain tissue and blood from 91 cases for the four antidepressants citalopram, duloxetine, mirtazapine and sertraline. The cases were classified according to their role in the cause of death, as follows: (A) concentrations where the drug was the sole cause of fatal intoxication; (B) concentrations where the drug contributed to a fatal outcome; and (C) concentrations where the drug was not related to the cause of death. The analytical method was successfully validated in brain tissue in terms of linearity, process efficiency, precision and accuracy. Quantification of analytes was performed by ultra-performance liquid chromatography with tandem mass spectrometry. Correlations between blood and brain concentrations were achieved with R2-values between 0.67 and 0.91. The following median brain-blood ratios were obtained: 3.71 for citalopram (range: 1.4-5.9), 11.0 for duloxetine (range: 5.0-21.6), 1.53 for mirtazapine (range: 1.02-4.71) and 7.38 for sertraline (range: 3.2-14.2). The S/R ratio of racemic citalopram was the same in brain (0.80) and blood (0.85), whereas the median citalopram/N-desmethylcitalopram ratio was higher in brain (9.1) than blood (4.1). The results of this study may serve as reference concentrations in brain for forensic cases.

Abstract
Complex diseases comprises of highly complicated etiology resulting in limited applicability of conventional targeted therapies. Consequently, conventional medicinal compounds suffer major failure when used for such disease conditions. Additionally, development of multidrug resistance (MDR), adverse drug reactions and clinical specificity of single targeted drug therapy has increased thrust for novel drug therapy. In this rapidly evolving era, natural product-based discovery of hybrid molecules or multi-targeted drug therapies have shown promising results and are trending now a days. Historically, nature has blessed human with different sources viz. plant, animal, microbial, marine and ethnopharmaceutical sources which has given a wide variety of medicinally active compounds. These compounds from natural origin are always choice of interest of medicinal chemists because of their minimum side effects. Hybrid molecules synthesized by fusing or conjugating different active molecules obtained from these sources are reported to synergistically block different pathways which contribute in the pathogenesis of complex diseases. This review strives to encompass all natural product-derived hybrid molecules which act as multi-targeting agents striking various targets involved in different pathways of complex diseased conditions reported in literature.

Abstract
Some vinyl hydrogels containing α-amino acid residues (l-phenylalanine, l-valine) were used as polyelectrolyte platforms for the evaluation of the controlled release of two antidepressants (paroxetine and duloxetine). The closer acidity constant (pKa) values of the two drugs show a closer release profile in physiological phosphate buffered saline (PBS) buffer (pH 7.40) and for long periods of time. The great electrostatic interaction forces between the COO- group of the hydrogel and the protonated secondary amino nitrogen of the drug are the main factor improving the release kinetics; this release was found to be slower compared to that of two structurally related drugs bearing the tertiary amino nitrogen atom (citalopram and trazodone). Moreover, at the lower value of pH 4.60, paroxetine showed a flatter release profile from the hydrogel containing the l-phenylalanine residues that, after six days, is half of that shown by duloxetine. Further effects due to steric and hydrophobic interactions may contribute to the different release profile. A further stimulation with alternating magnetic fields (AMF) of low frequency (20 kHz/50 W) enhanced the release of the drug at pH 7.40 from the hydrogel containing magnetic nanoparticles. Both AMF and PBS solution at pH 7.40 were used to trigger the 'on-demand' pulsatile paroxetine release from the nanocomposite hydrogel.

Abstract
Duloxetine is a second-generation selective serotonin and norepinephrine reuptake inhibitor used primarily for the treatment of depression. Relatively few fatalities have been reported in association with its use. Similarly, there are no known reports that provide a comprehensive analysis of blood, fluid and tissue samples in an overdose setting. Herein we present a fatal case of duloxetine toxicity with both the highest reported post-mortem blood concentration and a comprehensive toxicological analysis of duloxetine in femoral blood, vitreous humor, liver tissue, urine and gastric contents. In doing so, we hope to provide data that can assist both toxicologists and forensic pathologists with assessing duloxetine toxicity in the future.

Abstract
Vitreous humor (VH) is a gelatinous substance contained in the posterior chamber of the eye, playing a mechanical role in the eyeball. It has been the subject of numerous studies in various forensic applications, primarily for the assessment of postmortem interval and for postmortem chemical analysis. Since most of the xenobiotics present in the bloodstream are detected in VH after crossing the selective blood-retinal barrier, VH is an alternative matrix useful for forensic toxicology. VH analysis offers particular advantages over other biological matrices: it is less prone to postmortem redistribution, is easy to collect, has relatively few interfering compounds for the analytical process, and shows sample stability over time after death. The present study is an overview of VH physiology, drug transport and elimination. Collection, storage, analytical techniques and interpretation of results from qualitative and quantitative points of view are dealt with. The distribution of xenobiotics in VH samples is thus discussed and illustrated by a table reporting the concentrations of 106 drugs from more than 300 case reports. For this purpose, a survey was conducted of publications found in the MEDLINE database from 1969 through April 30, 2015.

Abstract
This paper describes a simple, rapid and sensitive liquid chromatography–tandem mass spectrometry assay for the determination of duloxetine in human plasma. A duloxetine stable labeled isotope (duloxetine d5) was used as an internal standard. Analyte and the internal standard were extracted from 100 μL of human plasma via solid phase extraction technique using Oasis HLB cartridges. The chromatographic separation was achieved on a C18 column by using a mixture of acetonitrile–5 mM ammonium acetate buffer (83:17, v/v) as the mobile phase at a flow rate of 0.9 mL/min. The calibration curve obtained was linear (r2≥0.99) over the concentration range of 0.05–101 ng/mL. Multiple-reaction monitoring mode (MRM) was used for quantification of ion transitions at m/z 298.3/154.1 and 303.3/159.1 for the drug and the internal standard, respectively. Method validation was performed as per FDA guidelines and the results met the acceptance criteria. A run time of 2.5 min for each sample made it possible to analyze more than 300 plasma samples per day. The proposed method was found to be applicable to clinical studies.

Abstract
A high-performance liquid chromatographic (HPLC) method is described for the determination of duloxetine hydrochloride in capsules. The method was based on pre-column derivatization with 4-chloro-7-nitrobenzo-2-oxa-1,3-diazole using the fluorimetric detection technique. Duloxetine hydrochloride was analyzed by HPLC using an Inertsil C18 column (5 μm, 150 × 4.6 mm) and mobile phase consisted of methanol and water (65:35, v/v). The fluorescence detector was adjusted at excitation and emission wavelengths of 461 and 521 nm, respectively. The linearity of the method was in the range of 10-600 ng/mL. Limits of detection and quantification were 0.51 and 1.53 ng/mL, respectively. The proposed method was successfully applied for determination of duloxetine hydrochloride in its pharmaceutical preparation. The results were in good agreement with those obtained using a reference method.

Abstract
The pharmaco-toxicological profile of duloxetine, a novel SNRI antidepressant, is still not completely known; in particular, intoxication cases have been scarcely studied. Here a duloxetine overdose case, in combination with other antidepressants and benzodiazepines, is reported and the chemical-clinical correlations discussed; this is probably the first detailed report of such a case. The patient referred to have ingested nine tablets of Cymbalta (more than 500 mg of duloxetine) and high amounts of four other drugs (venlafaxine, trazodone, sertraline and clonazepam). The patient was dozy and confused and some electrolyte imbalances were found. After gastrolavage, toxicological analyses revealed high plasma levels of duloxetine (384 ng/ml) and low levels of the other supposedly involved drugs. The overdose resulted to be not fatal and the outcome was relatively benign, also thanks to the fast emergency assistance. This case suggests that clinicians should be alerted to the possibility of toxic effects caused by simultaneous overdoses of duloxetine and other antidepressants and that caution should be used when prescribing more than one of these drugs to patients at risk of suicide.

Abstract
Serotonin–norepinephrine-reuptake inhibitors (SNRIs) and selective serotonin-reuptake inhibitors (SSRIs) belong to a new generation of antidepressants used in the treatment of depression and other mood disorders. SSRIs act as reuptake inhibitors primarily via the inhibition of the neuronal reuptake of serotonin (5-HT) in the CNS. SNRIs have additional inhibitory activity at noradrenaline-reuptake sites. Different analytical methods for the routine monitoring and toxicological screening of SNRIs and SSRIs have been developed. Rapid quantification is a necessity for clinical use, allowing the possibility of diagnostics. This review focuses on recent advances of the methods that concern the determination of SSRIs and SNRIs in human biological samples. Sample preparation methodologies are discussed, because sample pretreatment is the most limiting and crucial step in analysis of biological matrices. Furthermore, information concerning the mechanism of action, side effects and toxicity are also given.

Abstract
A rapid, sensitive and accurate liquid chromatographic-tandem mass spectrometry (LC-MS-MS) method is described for the determination of duloxetine in human plasma. Duloxetine was extracted from plasma using methanol and separated on a C18 column. The mobile phase consisting of a mixture of acetonitrile and 5mM ammonium acetate (45:55, v/v, pH 3.5) was delivered at a flow rate of 0.3 ml/min. Atmospheric pressure ionization (API) source was operated in positive ion mode. Multiple reaction monitoring (MRM) mode using the transitions of m/z 298.1-->m/z 44.0 and m/z 376.2-->m/z 123.2 were used to quantify duloxetine and internal standard (I.S.), respectively. The linearity was obtained over the concentration range of 0.1-50.0 ng/ml and the lower limit of quantitation (LLOQ) was 0.1 ng/ml. This method was successfully applied to pharmacokinetic study of a duloxetine formulation product after oral administration to healthy human subjects.

Abstract
Duloxetine is the most recent serotonin and norepinephrine reuptake inhibitor (SNRI) drug introduced for the therapy of depression. Thus, it is evident that there is a need for having on hand new reliable analytical methods for the determination of duloxetine plasma levels in depressed patients. The present paper deals with the development of a rapid and sensitive high-performance liquid chromatographic method for duloxetine analysis in human plasma. The assays were carried out using a C8 reversed-phase column and a mobile phase composed of 60% aqueous phosphate buffer containing triethylamine at pH 3.0 and 40% acetonitrile. The UV detector was set at 230 nm and loxapine was used as the internal standard. An original pre-treatment of plasma samples was developed, based on solid-phase extraction (SPE) with mixed-mode reversed phase-strong cation exchange cartridges (30 mg, 1 mL). The extraction yields values were higher than 90%. Linearity was found in the 2-200 ng mL(-1) duloxetine concentration range; the limit of quantitation was 2.0 ng mL(-1) and the limit of detection was 0.7 ng mL(-1). The method was applied to plasma samples from depressed patients undergoing therapy with duloxetine. Precision data and accuracy results were satisfactory and no interference from other drugs was found. Thus, the method seems to be suitable for the therapeutic drug monitoring of duloxetine in depressed patients' plasma.
