Int J Biol Macromol 2023; 241:124547. [PMID: 37094646 DOI: 10.1016/j.ijbiomac.2023.124547] [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: 02/14/2023] [Revised: 04/10/2023] [Accepted: 04/14/2023] [Indexed: 04/26/2023]
Abstract
The genotoxic and carcinogenic adverse effects of various drugs should be considered for assessing drug benefit/risk ratio. On that account, the scope of this study is to examine the kinetics of DNA damage triggered by three CNS acting drugs; carbamazepine, quetiapine and desvenlafaxine. Two precise, simple and green approaches were proposed for probing drug induced DNA impairment; MALDI-TOF MS and terbium (Tb3+) fluorescent genosensor. The results revealed that all the studied drugs induced DNA damage manifested by the MALDI-TOF MS analysis as a significant disappearance of the DNA molecular ion peak with the appearance of other peaks at smaller m/z indicating the formation of DNA strand breaks. Moreover, significant enhancement of Tb3+ fluorescence occurred, proportional to the amount of DNA damage, upon incubation of each drug with dsDNA. Furthermore, the DNA damage mechanism is examined. The proposed Tb3+ fluorescent genosensor showed superior selectivity and sensitivity and is significantly simpler and less expensive than other methods reported for the detection of DNA damage. Moreover, the DNA damaging potency of these drugs was studied using calf thymus DNA in order to clarify the potential safety hazards associated with the studied drugs on natural DNA.

Abstract
A novel fluorescent sensor based on an asymmetric anthracene derivative (SSAPA) was designed and synthesized. Using this molecule, a rapid and sensitive assay for detecting Tb3+ and ATP in aqueous solutions was established. The SSAPA molecule had excellent aggregation-induced emission (AIE) performance and good aqueous dispersion ability. This molecule could coordinate with Tb3+ and the fluorescence quenched linearly with the increase in the concentration of Tb3+ from 0.005 to 1.2 μM. Since both Tb3+ and adenosine triphosphate (ATP) have strong binding ability, ATP can compete with Tb3+ from the SSAPA/Tb3+ complex leading to fluorescence recovery. In this way, a brand-new fluorescent "turn-on" assay for ATP in the range from 0.01 to 0.4 μM was developed using the Tb3+-based complex probe. The detection limits for Tb3+ and ATP both reached single-digit nanomole per millilitre (2.8 nM and 4.5 nM, respectively), which demonstrated that this method has high sensitivity. Besides, Tb3+ and ATP also could be well detected in other complex environments such as real water samples or serum samples. This study provides a feasible assay for detecting trace amounts of Tb3+ and ATP in aqueous solutions.

Abstract
The pyridinedicarboxylate-Tb(III) complexes, TbPDC and Tb(PDC)3, as luminescent probes for ATP monitoring have been conveniently prepared and characterized by FT-IR, 1H-NMR, ESI-MS, UV-Vis, excitation, and emission spectroscopy. Interestingly, these two Tb(III) complexes were quenched by ATP by a similar mechanism via π-π stacking interaction between the chelating ligand and adenine moiety. The ability of luminescent probes applied for the determination of ATP in aqueous solution has been investigated. The dynamic ranges for the quantification of ATP are within 10-90 μM and 10-100 μM with detection limits of 7.62 and 11.20 μM for TbPDC and Tb(PDC)3, respectively. The results demonstrated that these luminescent probes would be a potential candidate assay for ATP monitoring in hygiene assessment.

J Pharm Biomed Anal 2020; 194:113806. [PMID: 33280995 PMCID: PMC7703390 DOI: 10.1016/j.jpba.2020.113806] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/04/2020] [Revised: 11/24/2020] [Accepted: 11/25/2020] [Indexed: 01/18/2023]
Abstract
A robust and reliable LC–MS/MS method for the quantification of RMP and RTP was optimized and validated. The novel method solved the major challenges of direct determination of RMP and RTP in biological matrix through improvement of LC retention, stability and recovery. The method was validated and successfully applied to mouse tissue distribution study. This method provides useful information for further study of remdesivir as well as extends the approach for phosphate determination. The method solved the major challenges for determining RMP and RTP in biological matrix such as LC retention, stability and recovery.
Remdesivir is a prodrug of the nucleotide analogue and used for COVID-19 treatment. However, the bioanalysis of the active metabolites remdesivir nucleotide triphosphate (RTP) and its precursor remdesivir nucleotide monophosphate (RMP) is very challenging. Herein, we established a novel method to separate RTP and RMP on a BioBasic AX column and quantified them by high-performance liquid chromatography-tandem mass spectrometry in positive electrospray ionization mode. Stepwise, we optimized chromatographic retention on an anion exchange column, improved stability in matrix through the addition of 5,5′-dithiobis-(2nitrobenzoic acid) and PhosSTOP EASYpack, and increased recovery by dissociation of tight protein binding with 2 % formic acid aqueous solution. The method allowed lower limit of quantification of 20 nM for RMP and 10 nM for RTP. Method validation demonstrated acceptable accuracy (93.6%–103% for RMP, 94.5%–107% for RTP) and precision (RSD < 11.9 % for RMP, RSD < 11.4 % for RTP), suggesting that it was sensitive and robust for simultaneous quantification of RMP and RTP. The method was successfully applied to analyze RMP and RTP in mouse tissues. In general, the developed method is suitable to monitor RMP and RTP, and provides a useful approach for exploring more detailed effects of remdesivir in treating diseases.

Abstract
Breast cancer which is the most commonly diagnosed cancer among women; have been known as a serious threat for health and life around the world. So development of an approach for early-stage diagnosis of breast cancer is vital. In this study, we designed a double aptamer-nanoparticle conjugates-based (DANP) complex for specific detection and visualization of MCF-7 cells using Mucin 1 (MUC 1) aptamer-conjugated gold nanoparticles (MUC1 apt - GNPs) and adenosine triphosphate (ATP) aptamer-conjugated CdTe quantum dots (ATP apt-QDs). The ATP apt-QDs was attached onto MUC1 apt - GNPs surface through Van der Waals forces and electrostatic interactions between ATP aptamer and GNPs leading to the formation of DANP complex. Atomic force microscopy asserted DANP complex formation. The imaging process was based on the recognition of MUC1 protein on the surface of MCF-7 cells by MUC1 aptamer and specific internalization of DANP complex into target cells (MCF-7). Existence of abundant amounts of ATP in lysosome led to release of ATP apt-QDs from the MUC1 apt-GNPs surface resulting in strong fluorescence emission. The flow cytometry analysis and fluorescence microscopy confirmed significant internalization of DANP complex into MCF-7 cells (target) in comparison with CHO cells (non-target). Based on the obtained results, the DANP complex possesses high potency for efficient detection and monitoring of breast cancer cells (MCF-7).

Abstract
Recently, it has been crucial to be able to detect and quantify small molecular targets simultaneously in biological samples. Herein, a simple and conventional double-T type microchip electrophoresis (MCE) based platform for the multiplex detection of quality indicator molecule targets in urine, using ampicillin (AMPI), adenosine triphosphate (ATP) and estradiol (E2) as models, was developed. Several programmable hairpin probes (PHPs) were designed for detecting different targets and triggering isothermal polymerase-catalyzed target recycling (IPCTR) for signal amplification. Based on the target-responsive aptamer structure of PHP (Domain I), target recognition can induce PHP conformational transition and produce extension duplex DNA (dsDNA), assisted by primers & Bst polymerase. Afterwards, the target can be displaced to react with another PHP and initiate the next cycle. After several rounds of reaction, the dsDNA can be produced in large amounts by IPCTR. Three targets can be simultaneously converted to dsDNA fragments with different lengths, which can be separated and detected using MCE. Thus, a simple double-T type MCE based platform was successfully built for the homogeneous detection of multiplex targets in one channel. Under optimal conditions, the assay exhibited high throughput (48 samples per hour at most, not including reaction time) and sensitivity to three targets in urine with a detection limit of 1 nM (ATP), 0.05 nM (AMPI) and 0.1 nM (E2) respectively. The multiplex assay was successfully employed for the above three targets in several urine samples and combined the advantages of the high specificity of programmable hairpin probes, the excellent signal amplification of IPCTR, and the high through-put of MCE which can be employed for screening in biochemical analysis.

Abstract
A kind of nitrogen doped carbon dots (NCDs) with excellent stable luminescence performance was prepared by pyrolysis using ethanolamine as precursor. By simply mixing solution of NCDs and calcein-Eu3+, a ratio fluorometric probe with carbon dots as "internal reference" and calcein-Eu3+ as recognition group was constructed for ATP detection. The fluorescence of the calcein can be selectively quenched by Eu3+, and can be restored when ATP was added because Eu3+ ions exhibit higher affinity to the oxygen-donor atoms originated from phosphates than that from carboxylate groups. Meanwhile, fluorescence of NCDs was not affected by Eu3+, calcein or ATP. By adding NCDs as "internal reference" in the above system, a new ratiometric strategy for detecting ATP was conducted. The dynamic linear range for ATP detection was 5.0 × 10-8 mol L-1~ 2.0 × 10-6 mol L-1, and the detection limit was 2.0 × 10-8 mol L-1.The method was successfully applied to detecting ATP in adenosine disodium triphosphate injection. Compared with calcein- Eu3+ probe without NCDs as reference, the ratio fluorometric probe effectively reduced interference and improved the accuracy and sensitivity.

Abstract
An electrochemical biosensor was developed for the detection of adenosine triphosphate (ATP) based on target-induced conformation switching and nicking endonuclease (NEase)-assisted signal amplification. The electrochemical biosensor was constructed by base pairing and target recognition. After capture DNA hybridized with the gold electrode, a significant current of Methylene Blue (MB) was obtained by differential pulse voltammetry. In the presence of ATP, the hairpin DNA formed a G-quadruplex structure due to the specific recognition between hairpin DNA and ATP. Then the exposed part of the target-aptamer complex hybridized with the 3'-terminus of capture DNA to form a specific nicking site for Nb.BbvCI, which led to NEase-assisted target-aptamer complex recycling. The released target-aptamer complex hybridized with the remaining capture DNA. Nb.BbvCI-assisted target-aptamer complex recycling caused the continuous cleavage of capture DNA with MB at its 5'-terminus, resulting in release of a certain amount of DNA fragment labeled with MB. Then the current value decreased significantly. The reduced current showed a linear range from 10 nM to 1 μM with a limit of detection as low as 3.4 nM. Furthermore, the proposed strategy can be used for the detection of similar substances.

Abstract
A new and sensitive spectrofluorimetric method has been proposed to determine trace amount of adenosine disodium triphosphate (ATP). The method is based on the fluorimetric interaction between gatifloxacin (GFLX)-aluminium (III) (Al(3+) ) complex and ATP and studied using UV-visible and fluorescence spectroscopy. Weak luminescence spectra of Al(3+) were enhanced after complexation with GFLX at 423 nm upon excitation at 272 nm due to energy transfer from the ligand to the Al(3+) ion. It was observed that the FL emission spectrum of GFLX-Al(3+) was enhanced significantly by the addition of ATP. Under the optimal conditions, the enhancement of FL intensity at 423 nm was responded linearly with the concentration of ATP in the range 1.3 × 10(-10) - 1.0 × 10(-8) mol L(-1) with correlation coefficient (r) of 0.9981. The limit of detection (LOD) was found to be 1.1 × 10(-11) mol L(-1) for ATP with the standard deviation (RSD) of 1.21% for five repeated measurement of 2.3 × 10(-8) mol L(-1) ATP. The presented method is simple, sensitive, free from coexisting interferents and can be applied successfully to determine ATP in the real samples.

Abstract
A target-induced structure-switching electrochemical aptasensor for sensitive detection of ATP was successfully constructed which was based on exonuclease III-catalyzed target recycling for signal amplification. With the existence of ATP, methylene blue (MB) labeled hairpin DNA formed G-quadruplex with ATP, which led to conformational changes of the hairpin DNA and created catalytic cleavage sites for exonuclease III (Exo III). Then the structure-switching DNA hybridized with capture DNA which made MB close to electrode surface. Meanwhile, Exo III selectively digested aptamer from its 3'-end, thus G-quadruplex structure was destroyed and ATP was released for target recycling. The Exo III-assisted target recycling amplified electrochemical signal significantly. Fluorescence experiment was performed to confirm the structure-switching process of the hairpin DNA. In fluorescence experiment, AuNPs-aptamer conjugates were synthesized, AuNPs quenched fluorescence of MB, the target-induced structure-switching made Exo III digested aptamer, which restored fluorescence. Under optimized conditions, the proposed aptasensor showed a linear range of 0.1-20 nM with a detection limit of 34 pM. In addition, the proposed aptasensor had good stability and selectivity, offered promising choice for the detection of other small molecules.

Abstract
A cost-effective microfluidic paper analysis device (μPAD) was developed with a special Z-folding design for controlling the fluidic flowing and substrate transportation. This presented μPAD can be easily fabricated through wax printing by using a solid ink printer which deposits wax onto the surface of a chromatographic paper, and then baked on a hotplate by penetrating the molten wax into the paper to create a hydrophobic barrier. After μPAD fabrication, liquid control and substrate transportation can be easily carried out by twice folding the μPAD following Z shape. The Z folding made two separated reagent holding zone connected while the detection reaction occurred with the connection. In this paper, a pathogens detection indicated by ATP quantification was took as a proof-in-principle application of using this presented μPAD, the limit of detection (LOD) was 1 μM for ATP detection and 2.6×10(7) CFU/mL for Salmonella live cell detection, which showed a great potential for Point-of-Care Testing (POCT) applications.

Highly selective and sensitive electrochemical biosensor for ATP based on the dual strategy integrating the cofactor-dependent enzymatic ligation reaction with self-cleaving DNAzyme-amplified electrochemical detection. Biosens Bioelectron 2014; 63:14-20. [PMID: 25048448 DOI: 10.1016/j.bios.2014.07.007] [Citation(s) in RCA: 49] [Impact Index Per Article: 4.9] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/03/2014] [Revised: 07/04/2014] [Accepted: 07/04/2014] [Indexed: 11/22/2022]
Abstract
A dual strategy that combines the adenosine triphosphate (ATP)-dependent enzymatic ligation reaction with self-cleaving DNAzyme-amplified electrochemical detection is employed to construct the biosensor. In this design, the methylene blue-labeled hairpin-structured DNA was self-assembled onto a gold electrode surface to prepare the modified electrode through the interaction of Au-S bond. In the procedure of ATP-dependent ligation reaction, when the specific cofactor ATP was added, the two split oligonucleotide fragments of 8-17 DNAzyme were linked by T4 DNA ligase and then released to hybridize with the labeled hairpin-structured DNA substrate. The linked 8-17 DNAzyme catalyzes the cleavage of the hairpin-structured substrate by the addition of Zn(2+), causing the methylene blue which contains high electrochemical activity to leave the surface of the gold electrode, therefore generating a dramatic decrease of electrochemical signal. The decrease of peak current was readily measured by square wave voltammetry and a relatively low detection limit (0.05 nM) was obtained with a linear response range from 0.1 to 1000 nM. By taking advantage of the highly specific cofactor dependence of the DNA ligation reaction, the proposed ligation-induced DNAzyme cascades demonstrate ultrahigh selectivity toward the target cofactor ATP. A catalytic and molecular beacons strategy is further adopted to amplify the electrochemical signal detection achieved by cycling and regenerating the 8-17 DNAzyme to realize enzymatic multiple turnover, thus one DNAzyme can catalyze the cleavage of several hairpin-structured substrates, which improves the sensitivity of the newly designed electrochemical sensing system.

Abstract
In this work, an ultrasensitive fluorescent polarization immunoassay (FPIA) method based on the quantum dot/aptamer/antibody/gold nanoparticles ensemble has been developed for the detection of adenosine triphosphate (ATP). DNA hybridization is formed when ATP is present in the PBS solution containing the DNA-conjugated quantum dots (QDs) and antibody-AuNPs. The substantial sensitivity improvement of the antibody-AuNPs-enhanced method is mainly attributed to the slower rotation of fluorescent unit when QDs-labeled oligonucleotides hybridize with antibody modified the gold nanoparticle. As a result, the fluorescent polarization (FP) values of the system increase significantly. Under the optimal conditions, a linear response with ATP concentration is ranged from 8×10(-12) M to 2.40×10(-4) M. The detection limit reached as low as 1.8 pM. The developed work provides a sensitive and selective immunoassay protocol for ATP detection, which could be applied in more bioanalytical systems.

Abstract
In spite of the promising applications of aptamers in the bioassays, the development of aptamer-based electrochemical biosensors with the improved limit of detection has remained a great challenge. A strategy for the amplification of signal, based on application of nanostructures as platforms for the construction of an electrochemical adenosine triphosphate (ATP) aptasensor, is introduced in the present manuscript. A sandwich assay is designed by immobilizing a fragment of aptamer on a nanoporous gold electrode (NPGE) and its association to second fragment in the presence of ATP. Consequently, 3, 4-diaminobenzoic acid (DABA), as a molecular reporter, is covalently attached to the amine-label of the second fragment, and the direct oxidation signal of DABA is followed as the analytical signal. The sensor can detect the concentrations of ATP as low as submicromolar scales. Furthermore, 3.2% decrease in signal is observed by keeping the aptasensor at 4 °C for a week in buffer solution, implying a desirable stability. Moreover, analog nucleotides, including GTP, UTP and CTP, do not show serious interferences and this sensor easily detects its target in deproteinized human blood plasma.

Abstract
Glutathione-bound gold nanoclusters (AuNCs@GSH) can emit reddish photoluminescence under illumination of ultraviolet light. The luminescence of the AuNCs@GSH is quenched when chelating with iron ions (AuNCs@GSH-Fe(3+)), presumably resulting from the effective electron transfer between the nanoclusters and iron ions. Nevertheless, we found that the luminescence of the gold nanoclusters can be restored in the presence of phosphate-containing molecules, which suggested the possibility of using AuNCs@GSH-Fe(3+) complexes as the selective luminescent switches for phosphate-containing metabolites. Phosphate-containing metabolites such as adenosine-5'-triphosphate (ATP) and pyrophosphate play an important role in biological systems. In this study, we demonstrated that the luminescence of the AuNCs@GSH-Fe(3+) is switched-on when mixing with ATP and pyrophosphate, which can readily be observed by the naked eye. It results from the high formation constants between phosphates and iron ions. When employing fluorescence spectroscopy as the detection tool, quantitative analysis for phosphate-containing metabolites such as ATP and pyrophosphate can be conducted. The linear range for ATP and pyrophosphate is 50 μM to sub-millimolar, while the limit of detection for ATP and pyrophosphate are ∼43 and ∼28 μM, respectively. Additionally, we demonstrated that the luminescence of the AuNCs@GSH-Fe(3+) can also be turned on in the presence of phosphate-containing metabolites from cell lysates and blood plasma.

Abstract
The capability of silver nanoparticles (SNP) as redox tag in the construction of an electrochemical aptasensor for the detection of adenosine triphosphate (ATP) is investigated in the present manuscript. To construct the aptasensor, a well-known ATP binding aptamer (ABA) splits into two segments. The first amino-labeled segment of the aptamer was covalently immobilized on 3-mercaptopropionic acid modified gold electrode surface by the formation of carbodiimide bond. The second segment was modified by SNPs and associated with the first segment in the presence of ATP. The direct oxidation signal of SNPs is followed as the analytical signal to detect ATP. The sandwich assay shows a suitable signal gain and importantly, a good response time. The sensor can detect the concentrations of ATP as low as micromolar scales with a desirable stability under optimum conditions. Furthermore, analog nucleotides including GTP, UTP and CTP, do not show serious interferences and this sensor readily detects its target in a complex media such as human blood plasma.

Abstract
Detection and quantification of small molecules have played essential roles in environmental analysis and clinical diagnosis. Aptamers are oligonucleic acids that bind to a specific target molecule with high specificity and affinity which are promising features for sensing small molecules. Electrochemical detection is an attractive way to exploit aptamer sensors (aptasensors) because of its high sensitivity, simple instrumentation, low cost, fast response and portability. Herein, we describe a label-free small molecular aptasensor based on a signal-amplification mechanism which uses gold nanoparticles. This aptasensor can selectively detect low nanomolar levels of ATP, the example target compound.

Abstract
A fluorimetric method based on fluorescence enhancement effect was developed for the determination of adenosine 5'-monophosphate (AMP) with 9-anthracene carboxylic acid (9-ANCA)-cetyl trimethyl ammonium bromide (CTAB) system. Fluorescence intensity of 9-ANCA was decreased by the addition of CTAB but addition of AMP again rose the intensity of 9-ANCA gradually. The observed fluorescence enhancement is attributed to the competitive binding reaction of 9-ANCA and adenosine to CTAB. The enhancement in the fluorescence intensity was found proportional to the concentration of AMP over the range 2.0 × 10(-4) to 1.2 × 10(-3) mol dm(-3). The ion pair complex is formed spontaneously between 9-ANCA and CTAB. Since the binding interaction is larger for the adenosine-CTAB pair, the fluorophore 9-ANCA will be released. The quantum yield of free 9-ANCA is higher therefore its fluorescence observed at 417 nm wavelength is enhanced. This mechanism of competitive molecular interaction is further confirmed by conductometric measurements. The method was applied successfully for the determination of AMP from pharmaceutical sample. The method is more selective, sensitive and relatively free from interferences.

Abstract
A simple spectrofluorimetric method is described for the determination of buparvaquone (BPQ), based on its quenching effect on the fluorescence intensity of Tb(3+)-deferasirox (DFX) complex as a fluorescent probe. The excitation and emission wavelengths were 328 and 545nm, respectively. The optimum conditions for determination of BPQ were investigated considering the effects of various affecting parameters. The variations in fluorescence intensity of the system showed a good linear relationship with the concentration of BPQ in the range of 10-1500μgL(-1), its correlation coefficient was 0.999 with the detection and quantification limits of 1.1 and 3.4μgL(-1), respectively. Linearity, reproducibility, recovery, limits of detection and quantification made the method suitable for BPQ assay in biological fluids, meat, dairy products and BPQ parenteral solutions (vials). The method was applied to real samples of serum and milk of three cows receiving BPQ.

Abstract
The characteristics of host-guest complexation between cucurbit[n]uril (CB[n], n=5, 6, 7, 8) and sanguinarine (SA) were investigated by spectrofluorimetry. The result showed that CB[n] (n=5, 6, 7, 8) reacted with SA to form an inclusion complex. At the optimum reaction conditions, the rectilinear calibration graphs were obtained in the range from 0.1 to 2800 ng mL(-1) for the investigated drug, with correlation coefficients 0.9998, 0.9997, 0.9999 and 0.9997 and detection limits 0.052, 0.26, 0.03 and 0.058 ng mL(-1) using CB[5], CB[6], CB[7], and CB[8], respectively. The apparent association constants of the complexes were 1.23 x 10(4), 6.73 x 10(3), 4.53 x 10(4) and 1.21 x 10(4) L mol(-1), for the reagents in the same order. The result demonstrated that CB[7] exhibited a higher fluorescence signal than CB[5], CB[6], and CB[8]. The proposed method was successfully applied for the determination of the drug in human urine and serum samples.

Abstract
A new spectrofluorimetric method was developed for the determination of trace amounts of DNA using the calcein as a fluorescent probe. In the presence of appropriate amounts of the cationic surfactant cetyl trimethyl ammonium bromide (CTAB), the anionic dye calcein dimerizes. The weak fluorescence intensity of the dimer was enhanced by adding DNA at pH 6-7. The interaction between calcein-CTAB and DNA was studied on the basis of this behavior and a new method was developed for determining DNA. Under the optimal conditions, the enhanced fluorescence intensity was in proportion to the concentration of DNA in the range of 4.0x10(-6) to 8.0x10(-5) g L(-1) for fsDNA and thermally denatured ctDNA (4.5x10(-6) to 9.0x10(-5) g L(-1)). The detection limits (S/N=3) were 2.0x10(-6) and 2.2x10(-6) g L(-1), respectively. This method was used for determining the concentration of DNA in synthetic samples with satisfactory results.
