Abstract
Alectinib is known as an effective targeted drug, which has excellent therapeutic effect on non-small cell lung cancer and can significantly prolong the survival of patients. Therapeutic drug monitoring is necessary due to the photo-instability of alectinib and the individual differences in patients. In this work, a porous polydopamine graphene oxide composite (PDAG) was prepared by a simple surface modification method. A PDAG-based pipette-tip solid-phase extraction (PT-SPE) coupled with HPLC-UV detection was proposed for the separation and detection of alectinib and its active metabolite M4 in plasma. The method was methodologically validated and showed good linearity in the range of 50-5000 ng mL-1 (R2 > 0.9995). The limit of detection (LOD) was 4.8 ng mL-1 and 3.9 ng mL-1 for alectinib and M4, respectively, and the limit of quantitation (LOQ) was 16.1 ng mL-1 and 13.1 ng mL-1, respectively. The intra-day and inter-day precision expressed by coefficient of variation was less than 4.8 %. The recovery of this method ranged from 84.9 % to 103.5 % with a standard deviation of less than 4.3 %. In conclusion, the established method is accurate, stable and inexpensive, and can be used to monitor the levels of alectinib and M4 in plasma, which provide technical and data support for exploring optimal individualized remedial dosing regimens.

Medicina (B Aires) 2023; 59:medicina59030441. [PMID: 36984441 PMCID: PMC10053830 DOI: 10.3390/medicina59030441] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/22/2023] [Revised: 02/18/2023] [Accepted: 02/20/2023] [Indexed: 02/25/2023] Open
Abstract
Background and Objectives: This study presents the development and validation of the 96-microwell-based spectrofluorimetric (MW-SFL) and high performance liquid chromatography (HPLC) with fluorescence detection (HPLC-FD) methods for the quantitation of alectinib (ALC) in its bulk powder form and in urine samples. Materials and Methods: The MW-SFL was based on the enhancement of the native fluorescence of ALC by the formation of micelles with the surfactant cremophor RH 40 (Cr RH 40) in aqueous media. The MW-SFL was executed in a 96-microwell plate and the relative fluorescence intensity (RFI) was recorded by utilizing a fluorescence plate reader at 450 nm after excitation at 280 nm. The HPLC-FD involved the chromatographic separation of ALC and ponatinib (PTB), as an internal standard (IS), on a C18 column and a mobile phase composed of methanol:potassium dihydrogen phosphate pH 7 (80:20, v/v) at a flow rate of 2 mL min–1. The eluted ALC and PTB were detected by utilizing a fluorescence detector set at 365 nm for excitation and 450 nm for emission. Results: Validation of the MW-SFL and HPLC-FD analytical methods was carried out in accordance with the recommendations issued by the International Council for Harmonization (ICH) for the process of validating analytical procedures. Both methods were efficaciously applied for ALC quantitation in its bulk form as well as in spiked urine; the mean recovery values were ≥86.90 and 95.45% for the MW-SFL and HPLC-FD methods, respectively. Conclusions: Both methodologies are valuable for routine use in quality control (QC) laboratories for determination of ALC in pure powder form and in human urine samples.

Abstract
Alectinib and its metabolite, M4, have demonstrated a satisfactory clinical therapeutic effect in the treatment of anaplastic lymphoma kinase-positive advanced non-small-cell lung cancer. Due to individual differences among patients, therapeutic drug monitoring (TDM) is critical for guaranteeing appropriate clinical drug use. To realize TDM for alectinib and its metabolite, M4, a honeycomb phenol-formaldehyde resin (PFR) with excellent hydrophilic properties, abundant adsorption force, and a stable porous structure was synthesized by modifying the porogens F127 and P123. The prepared PFR was employed as an adsorbent in a simple and efficient spin-column solid-phase extraction (SPE) process. A rapid method for detecting alectinib and its metabolite M4 in urine was thereby established. The established method showed a linear range of 0.0200 μg mL-1-5.00 μg mL-1 and the recovery range of 98.8-103% for spiked urine samples, with relative standard deviations of ≤ 4.87% (n = 3). Our results proved the practicability of the proposed honeycomb-PFR spin-column SPE method in TDM for alectinib and its metabolite, M4.

Development and validation of UPLC-MS/MS method for the simultaneous quantification of anaplastic lymphoma kinase inhibitors, alectinib, ceritinib, and crizotinib in Wistar rat plasma with application to bromelain-induced pharmacokinetic interaction. J Pharm Biomed Anal 2021; 204:114276. [PMID: 34325247 DOI: 10.1016/j.jpba.2021.114276] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/21/2020] [Revised: 07/11/2021] [Accepted: 07/20/2021] [Indexed: 12/29/2022]
Abstract
Bromelain, the aqueous extract of pineapple, has been used as a food supplement with reported nutritional and therapeutic benefits. Bromelain has anti-cancer, anti-inflammatory, antithrombotic, and fibrinolytic effects. Anaplastic lymphoma kinase (ALK) inhibitors, including alectinib (ALC), ceritinib (CER), and crizotinib (CRZ), have been efficiently used in the management of non-small cell lung cancer (NSCLC). The solubility of ALC, CER, and CRZ is much higher at low acidic pH (pH 1) and it decreases as the pH increases affecting their absorption with a subsequent decrease in their bioavailability. It was thought that the intake of bromelain could result in a decrease in the bioavailability of ALC, CER, and CRZ due to bromelain-induced alkalizing effect following digestion. On the contrary, bromelain could possibly increase plasma exposure of the cited drugs due to its known muco-permeation enhancing effect. The therapeutic-anticancer effect of bromelain can be possibly increased/enhanced with concomitant intake of other anticancer medications or it can add to the value of food supplements for its known nutritional benefits. Thus, this work aims at studying the possibility of any PK interaction when bromelain was taken while on ALC/CER/CRZ therapy. In this work, a new UPLC-MS/MS method was developed and validated for the simultaneous determination of ALC, CER, and CRZ in rat plasma. Further application of the proposed method was performed to test the possibility of the PK interaction between bromelain and the selected ALK inhibitors in Wistar rats. Simple protein precipitation with acetonitrile was used for sample preparation. Chromatographic analysis was performed on Waters BEH™ C18 column with a mixture of acetonitrile/water containing 0.1 % formic acid (70: 30, v/v) as the mobile phase. The method permitted the analysis of ALC, CER, and CRZ in concentration ranges of 2-200, 0.4-200, and 4.0-200 ng/mL, respectively. Bromelain administration caused a significant decrease in plasma levels of CER and CRZ with lowered Cmax, AUC0-t and AUC0-∞, along with an increase in the apparent clearance. However, no significant effect was noticed with ALC. Thus, attention should be paid to avoid the intake of bromelain with CER or CRZ.

Abstract
Alectinib is a central nervous system-active small molecule anaplastic lymphoma kinase (ALK) inhibitor that is effective in the treatment of patients with ALK positive tumors, including advanced non-small cell lung cancers and lymphomas. A simple, isocratic high-performance liquid chromatography–photo diode array detection (HPLC–PDA) assay for measurement of alectinib in human plasma is described. Alectinib is extracted from the plasma matrix by addition of methanol, followed by centrifugation and acidification with 0.1% formic acid. It elutes with a run time of 4.6 min using a 250 mm × 4.6 mm RP-C18 column with 0.1% aqueous formic acid and methanol (35:65, v/v) and a flow rate of 1 mL/min. Detection was at 339 nm. Linear calibration plots were achieved in the range of 0.1–20 μg/mL for alectinib (r2 = 0.9996). With limits of detection and quantification of 0.05 and 0.1 μg/mL, respectively, and excellent precision (%CV < 10%), accuracy (bias < ±12%), and recovery (>97%) within the 1–20 μg/mL concentration range, this assay was suitable for measuring pre-dose alectinib concentrations in an adolescent receiving 600-mg doses twice daily.

Abstract
A novel small molecule tyrosine kinase inhibitor 6-[6-Amino-5-[(1R)-1-(2,6-dichloro-3-fluorophenyl)ethoxy]-3-pyridyl]-1'-methylspiro[indoline-3,4'-piperidine]-2-one (SMU-B) had good activity against ALK (anaplastic lymphoma kinase) and ROS1 (c-ros oncogene 1) targets in non-small-cell lung cancer. The excellent bioactivity of SMU-B highlights the importance of determining its metabolic traits, which could provide meaningful information for further pharmacokinetic studies of SMU-B. In this work, we studied the metabolism of SMU-B in human liver microsomes. Three metabolites of SMU-B were identified by a quadrupole-time of flight tandem mass spectrometer (Q-TOF-MS), and the metabolic pathways of SMU-B were demethylation, dehydrogenation and oxidation. CYP3A4/5 was the principal isoform involved in SMU-B metabolism, as shown by chemical inhibition and recombination human enzyme studies. Additionally, a predication with a molecular docking model confirmed that SMU-B could interact with the active sites of CYP3A4 and CYP3A5. This study illuminates the metabolic profile of the anti-tumor drug SMU-B, which will accelerate its clinical use.

Abstract
Background In this work, we aim to develop and validate a fast, simple, and sensitive method for the quantitative determination of flibanserin and the exploration of its pharmacokinetics. Methods Ultra-performance liquid chromatography-tandem mass spectrometry (UHPLC-MS/MS) was the method of choice for this investigation and carbamazepine was selected as an internal standard (IS). The plasma samples were processed by one-step protein precipitation using acetonitrile. The highly selective chromatographic separation of flibanserin and carbamazepine (IS) was realised using an Agilent RRHD Eclipse Plus C18 (2.1 × 50 mm, 1.8 µ) column with a gradient mobile phase consisting of 0.1% formic acid in water and acetonitrile. The analytes were detected using positive-ion electrospray ionization mass spectrometry via multiple reaction monitoring (MRM). The target fragment ions were m/z 391.3 → 161.3 for flibanserin and m/z 237.1 → 194 for carbamazepine (IS). The method was validated by linear calibration plots over the range of 100-120,000 ng/mL for flibanserin (R2 = 0.999) in rat plasma. Results The extraction recovery of flibanserin was in the range of 91.5-95.8%. The determined inter- and intra-day precision was below 12.0%, and the accuracy was from - 6.6 to 12.0%. No obvious matrix effect and astaticism was observed for flibanserin. The target analytes were long-lasting and stable in rat plasma for 12 h at room temperature, 48 h at 4 °C, 30 days at - 20 °C, as well as after three freeze-thaw cycles (from - 20 °C to room temperature). The proposed method has been fully validated and successfully applied to the pharmacokinetic study of flibanserin.

Abstract
Dacomitinib is a highly selective irreversible small-molecule inhibitor of the human epidermal growth factor receptor (HER) family of tyrosine kinases. A simple and quick bioanalytical method was completely developed and validated for the assay and pharmacokinetic investigation of dacomitinib in rat plasma using ultra-performance liquid chromatography tandem mass spectrometry (UPLC-MS/MS). Proteins in 0.1 mL plasma samples were prepared by precipitant acetonitrile containing ibrutinib as the internal standard (IS). Separation of the analyte from plasma samples was carried out on an Acquity UPLC BEH C18 column using acetonitrile and 0.1% formic acid in water as mobile phase for gradient elution. The total run time and the elution time of dacomitinib were 3.0 min and 1.07 min, respectively. Positive-ion electrospray ionization (ESI) and multiple reaction monitoring (MRM) on a triple quadrupole tandem mass spectrometer were used for detection at the transitions of m/z 470.1 → 124.1 for dacomitinib and m/z 441.2 → 84.3 for ibrutinib (IS), respectively. In the range of 1-150 ng/mL, the calibration curve of dacomitinib was linear with a lower limit of quantitation (LLOQ) of 1 ng/mL. Mean recovery of dacomitinib in plasma was in the range of 76.9-84.1%. The inter- and intra-day precision (RSD) was in the scope of 1.7-8.7% and the accuracy (RE) ranged from -6.1 to 8.5%. Stability studies under different conditions were indicated to be stable. A pharmacokinetic study after oral administration of 40 mg/kg dacomitinib in rats illustrated the applicability of the new presented determination of dacomitinib.

Abstract
Several second and third generation ALK inhibitors have been introduced in recent years. A bioanalytical assay for simultaneous quantification of alectinib, brigatinib, and lorlatinib was developed and validated for human plasma. The method was also partially validated for diluted mouse plasma and tissue homogenates of brain, liver, kidney, and spleen. Samples (40 μl) were pretreated in a 96-well plate by protein precipitation with acetonitrile containing the internal standard [2H8]-alectinib. After chromatographic separation on an ethylene bridged octadecyl silica column by gradient elution at 600 μl/min using 1% (v/v) formic acid (in water) and acetonitrile, compounds were ionized by a turbo electrospray and monitored by selected reaction monitoring on a triple quadrupole mass spectrometer. Validation was performed in a 2-2000 ng/ml concentration range for alectinib and lorlatinib and a 4-4000 ng/ml range for brigatinib. Precisions (within-day and between-day) were in the range 2.2-15.0% and accuracies were in between 87.2 and 110.2% for all matrices and levels. Compounds were sufficiently stable under most investigated conditions. Results of a pilot pharmacokinetic and tissue distribution study for brigatinib in mice are reported. Finally, successful incurred samples reanalysis of tissue homogenate samples containing brigatinib and lorlatinib is presented. Lorlatinib homogenate samples were also successfully reanalyzed using a second independent assay (cross-validation).
