[PMID: 38897013 DOI: 10.1016/j.talanta.2024.126440] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/05/2024] [Revised: 06/12/2024] [Accepted: 06/14/2024] [Indexed: 06/21/2024]
Abstract
Owing to their incomplete digestion in the human body and inadequate removal by sewage treatment plants, antiepileptic drugs (AEDs) accumulate in water bodies, potentially affecting the exposed humans and aquatic organisms. Therefore, sensitive and reliable detection methods must be urgently developed for monitoring trace AEDs in environmental water samples. Herein, a novel phenylboronic acid-functionalized magnetic cyclodextrin microporous organic network (Fe3O4@CD-MON-PBA) was designed and synthesized via the thiol-yne click post-modification strategy for selective and efficient magnetic solid-phase extraction (MSPE) of trace AEDs from complex sample matrices through the specific B-N coordination, π-π, hydrogen bonding, electrostatic, and host-guest interactions. Fe3O4@CD-MON-PBA exhibited a large surface area (118.5 m2 g-1), rapid magnetic responsiveness (38.6 emu g-1, 15 s), good stability and reusability (at least 8 times), and abundant binding sites for AEDs. Under optimal extraction conditions, the proposed Fe3O4@CD-MON-PBA-MSPE-HPLC-UV method exhibited a wide linear range (0.5-1000 μg L-1), low limits of detection (0.1-0.5 μg L-1) and quantitation (0.3-2 μg L-1), good anti-interference ability, and large enrichment factors (92.2-104.3 to 92.3-98.0) for four typical AEDs. This work confirmed the feasibility of the thiol-yne click post-synthesis strategy for constructing novel and efficient multifunctional magnetic CD-MONs for sample pretreatment and elucidated the significance of B-N coordination between PBA and N-containing AEDs.

Abstract
Favipiravir and remdesivir are drugs to treat COVID-19. This study aims to find an optimum and validated method for simultaneous analysis of favipiravir and remdesivir in Volumetric Absorptive Microsampling (VAMS) by Ultra High-Performance Liquid Chromatography-Tandem Mass Spectrophotometry. The use of VAMS can be an advantage because the volume of blood is small and the sample preparation process is simple. Sample preparation was done by precipitation of protein using 500 μL of methanol. Analysis was carried out by ultra high-performance liquid chromatography-tandem mass spectrophotometry with ESI+ and MRM with m/z 157.9 > 112.92 for favipiravir, 603.09 > 200.005 for remdesivir, and at m/z 225.968 > 151.991 for acyclovir as the internal standard. The separation was carried out using an Acquity UPLC BEH C18 column (100 × 2.1 mm; 1.7 m), 0.2% formic acid-acetonitrile (50:50), flow rate was 0.15 mL/min, and column temperature was 50°C. The analytical method has been validated with the requirements issued by the Food and Drug Administration (2018) and European Medicine Agency (2011). The calibration range of favipiravir is 0.5-160 μg/mL and 0.002-8 μg/mL for remdesivir.

[PMID: 36030754 DOI: 10.1016/j.jpba.2022.115017] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/13/2022] [Revised: 08/16/2022] [Accepted: 08/19/2022] [Indexed: 11/21/2022]
Abstract
The plasma concentration of lamotrigine (LTG) and its metabolites has great interindividual variability. An UHPLC-MS/MS method for simultaneous determination of LTG and lamotrigine N2-glucuronide (LTG N2-GLUC), lamotrigine N2-oxide was developed, validated, and applied in 58 plasma samples. The ion transition was m/z 256.0 > 144.9 for LTG, 432.1 > 256.0 for LTG N2-GLUC, 272.2 > 241.9 for LTG N2-oxide, and 259.1 > 144.8 for LTG-13C3 (internal standard). The flow rate was 0.4 mL/min with a run time of 3 min. The calibration range was 0.025-2 mg/L for LTG and LTG N2-GLUC, and 0.000625-0.05 mg/L for LTG N2-oxide. For all analytes, the intra-day and inter-day bias and imprecision were -11.7-5.7 % and less than 14.3 %, and the internal standard normalized recovery and matrix factor were 91.7-101.5 % and 98.1-110.1 % with CV < 13. 7%. Ten- and twenty-fold dilution with blank plasma did not affect the analysis. All analytes were stable in plasma at room temperature for 8 h, at -80 °C for 80 days, and after 3 freeze-thaw cycles. The LTG N2-GLUC/LTG ratio was 0.44 in LTG monotherapy group. The ratio was reduced to 0.17 when co-administrated with valproic acid, while elevated to 0.82 when co-administrated with enzyme inducer. In conclusion, this method is suitable for simultaneous determination of LTG, LTG N2-GLUC and LTG N2-oxide in human plasma.

Abstract
Background:
Lamotrigine (LTG) is a broad-spectrum and first-line anti-epileptic drug.
To monitor the serum levels of LTG in epileptic seizures patients, high-performance liquid chromatography
with diode-array detection (HPLC-DAD) and ultra-performance liquid chromatography--
tandem mass spectrometry (UPLC-MS/MS) methods were established and compared.
Methods:
Imatinib was used as the internal standard (IS) for both methods. LTG and IS were detected
at 246 nm by HPLC-DAD. In UPLC-MS/MS, LTG and IS positive ion were detected by
multiple reaction monitoring (MRM), with m/z of 256/210.9 and 494/394.02, respectively. A total
of 37 blood samples from epileptic patients were determined and studied by these two methods.
Results:
There was an acceptable linearity for the two methods. The concentration range of LTG
was 0.59 ~ 22.20 mg/L by HPLC, and 0.28 ~ 23.97 mg/L by UPLC-MS/MS. The Pearson regression
coefficient of Deming regression was 0.9653 (95% CI: 0.9332 to 0.9821). Bland–Altman
method demonstrated that the concentration of LTG determined by UPLC-MS/MS was 8.3% higher
than that determined by HPLC (limits of agreement, -32.0% to +48.6%).
Conclusion:
There was a significant correlation between the two methods. Both HPLC and UPLC-
MS/MS can be used for routine clinical monitoring of LTG.

Abstract
A dual-template magnetic molecularly imprinted polymer (Dt-MMIP) with a specific recognition capability for carbamazepine (CBZ) and lamotrigine (LTG) was synthesized using methacrylic acid as a functional monomer, and ethylene glycol dimethylmethacrylate as a cross-linking agent. A magnetic non-molecularly imprinted polymer without templates (MNIP) was also prepared using the same procedure. The prepared polymers were characterized using scanning electron microscopy, Fourier-transform infrared spectroscopy and adsorption experiments. Results indicated that both Dt-MMIPs and MNIPs were microspherical nanoparticles, and the surface of the Dt-MMIP was rougher than that of the MNIP. In addition, the prepared Dt-MMIPs possessed a higher adsorption capacity and better selectivity for CBZ and LTG than the MNIPs. The maximum static adsorption capacities of Dt-MMIP for CBZ and LTG were 249.5 and 647.9 μg g-1, respectively, whereas those of MNIP were 75.8 and 379.8 μg g-1, respectively. The obtained Dt-MMIPs were applied as a magnetic solid-phase extraction sorbent for the rapid and selective extraction of CBZ and LTG in rat serum samples, and determination was performed by high-performance liquid chromatography with UV detection (HPLC-UV). The developed method of dispersive SPE based on Dt-MMIPs coupled to HPLC-UV has good rapidity and selectivity, and application prospects in serum.

Abstract
Background Cyclophosphamide is a nitrogen mustard chemotherapy drug that damages DNA through alkylation in the DNA base and produces DNA adducts. Alkylation that occurs in the N7 position of guanine base has a cytotoxic effect which is useful for cancer therapy. However, the alkylation that occurs in the O6 position of guanine bases can have mutagenic and carcinogenic effects that can trigger secondary cancer. This carcinogenic compound can be found in very low concentrations in cancer patients who had been receiving alkylating agents as their anticancer therapy. Analysis of O6-methylguanine can be one of the ways of therapeutic drug monitoring to avoid secondary cancer risk. This study aims to develop a sensitive, selective, and validated analytical method using Ultra-High-Performance Liquid Chromatography-Tandem Mass Spectrometry (UPLC-MS/MS). Methods Analysis of O6-methylguanine was done in Dried Blood Spot (DBS) and using allopurinol as an internal standard. The optimal analysis conditions were obtained using a C18 Acquity® Bridged Ethylene Hybrid (BEH) column (1.7 µm, 100 mm x 2.1 mm); mobile phase was 0.05% formic acid - acetonitrile (95:5 v/v); flow rate 0.1 mL/minute; gradient elution for 6 minutes; and detection at m/z 165.95 > 149 for O6-methylguanine and m/z 136.9 > 110 for allopurinol. Results The present study has fulfilled the FDA validation parameter requirements. The method provides rapid, sensitive, and selective analysis of O6-methylguanine using UPLC-MS/MS with a linear concentration range between 0.5–20 ng/mL.

Abstract
Dried blood spot as biosampling method offers a less invasive and easier procedure. This study aimed to develop the validated analytical method of doxorubicin hydrochloride and doxorubicinol simultaneously in dried blood spot with hexamethylphosphoramide as the internal standard. A total of 30 μL blood was spotted on DBS paper and dried for 3 hours before it was extracted by protein precipitation method using water and methanol. The separation was performed on column Acquity UHPLC BEH C-18 (2.1 × 100 mm; 1.7 μm), with 0.15 mL/min flow rate and using 0.1% acetic acid and acetonitrile as mobile phase in gradient elution for 7 min. Quantification analysis was performed by a triple quadrupole mass spectrometry with electrospray ionization (ESI) in positive ion mode. The multiple reaction monitoring (MRM) was set at m/z 544.22 > 397.06 for doxorubicin hydrochloride; m/z 546.22 > 361.05 for doxorubicinol; and m/z 180.03 > 135.16 for hexamethylphosphoramide. The lower limit of quantitation was 10 ng/mL for doxorubicin and 4 ng/mL for doxorubicinol. Concentration range acquired was 10–200 ng/mL for doxorubicin and 4–100 ng/mL for doxorubicinol. The precision and accuracy were within acceptable criteria of <15%. Dried blood spot samples acquired was stable for at least 30 days before analysis. This method fulfilled the validation requirement refers to Bioanalytical Method Validation Guideline of European Medicines Agency 2011 and US Food and Drug Administration 2018.

Abstract
Background:
Lamotrigine (LTG), topiramate (TPM), and oxcarbazepine (OXC) are
commonly used antiepileptic drugs. The bioactivity and toxicity of these drugs were related to their
blood concentrations which varied greatly among individuals and required to be monitored for dose
adjustment. However, the commercial method for monitoring of these drugs is not available in China.
Methods:
A UHPLC-MS/MS method for simultaneous determination of LTG, TPM, OXC, and OXC
active metabolite (10,11-dihydro-10-hydroxycarbazepine, MHD) was developed and validated according
to the guidelines and applied in clinical practice.
Results:
he separation was achieved by using methanol and water (both contain 0.1% formic acid)
at 0.4 mL/min under gradient elution within 3 min. For all analytes, the isotope internal standard was
used; the selectivity was good without significant carry over; LTG and TPM were linear between
0.06 to 12 mg/L while OXC and MHD were linear between 0.03 to 6 mg/L, the upper limit could be
10-fold higher because 10-fold dilution with water did not affect the results; the intra-day and interday
bias and imprecision were -13.11% to 5.42% and < 13.32%; the internal standard normalized recovery
and matrix factor were 90.95% to 111.94% and 95.57% to 109.91%; and all analytes were
stable under tested conditions. LTG and OXC-D4 shared two ion pairs m/z 257.1 > 212.0 and 257.1 >
184.0, and m/z 257.1 > 240.0 was suggested for OXC-D4 quantitation. Lamotrigine and lamotrigine-
13C3 shared three ion pairs m/z 259.0 > 214.0, 259.0 > 168.0 and 259.0 > 159.0, and m/z 259.0 >
144.9 was suggested for LTG-13C3 quantitation. CBZ had a slight influence on OXC analysis only at
0.225 mg/L (bias, 20.24%) but did not affect MHD analysis. Optimization of chromatography conditions
was useful to avoid the influence of isobaric mass transitions on analysis. This method has been
successfully applied in 208 patients with epilepsy for dose adjustment.
Conclusions:
An accurate, robust, rapid, and simple method for simultaneous determination of LTG,
TPM, OXC, and MHD by UHPLC-MS/MS was developed, validated, and successfully applied in patients
with epilepsy for dose adjustment. The experiences during method development, validation,
and application might be helpful for other researchers.

Abstract
Objective: Ethinyl estradiol and levonorgestrel as a combination of oral contraceptive drugs have very low dosage levels; hence, a highly sensitive and selective method of using ultra-performance liquid chromatography–tandem mass spectrometry (UPLC-MS/MS) is needed. Materials and Methods: This method was developed using prednisone as an internal standard, thus the purpose of this research was to get the optimum condition. The analytical method had been fully validated according to the European Medicines Agency guidelines, 2011. A reverse-phase chromatography separation was performed on ACQUITY UPLC ethylene bridged hybrid C18 column (1.7 μm, 2.1 × 50mm), eluted at a 0.3 mL/min flow rate under a gradient of mobile phase of 0.1% formic acid in water and acetonitrile within 5 min. Sample preparation used protein precipitation followed by liquid–liquid extraction. Quantification analysis was performed by a triple quadrupole mass spectrometry with electrospray ionization in positive-ion mode. The multiple reaction monitoring was set at m/z: 530.16 → 171.08 for ethinyl estradiol derivatized by dansyl chloride; m/z: 313.16 → 245.10 for levonorgestrel; and m/z: 359.10 → 147.04 for prednisone. Results: The validated method was accurate, precise, and sensitive with a lower limit of quantification at 5 and 100 pg/mL for ethinyl estradiol and levonorgestrel, respectively.

Abstract
Combination of asenapine with valproic acid received regulatory approval for acute treatment of schizophrenia and maniac episodes of bipolar disorders. A simple LC–MS/MS method was developed and validated for simultaneous quantification of asenapine and valproic acid in human plasma. Internal standards were added to 300 μL of plasma sample prior to liquid–liquid extraction using methyl tertiary butyl ether (MTBE). Chromatographic separation was achieved on Phenomenex C18 column (50 mm×4.6 mm, 5 μm) in isocratic mode at 40 °C. The mobile phase used was 10 mM ammonium formate–acetonitrile (5:95, v/v) at a constant flow rate of 0.8 mL/min monitored on triple quadrupole mass spectrometer, operating in the multiple reaction monitoring (MRM) mode. The injection volume used for LC–MS/MS analysis was 15 μL and the run time was 2.5 min. These low run time and small injection volume suggest the high efficiency of the proposed method. The method was validated over the concentration range of 0.1–10.02 ng/mL and 10–20,000 ng/mL for asenapine and valproic acid respectively. The method recoveries of asenapine (81.33%), valproic acid (81.70%), gliclazide (78.45%) and benzoic acid (79.73) from spiked plasma samples were consistent and reproducible. The application of this method was demonstrated by a pharmacokinetic study in 8 healthy male volunteers with 5 mg asenapine and 250 mg valproic acid administration.
