Background: Marbofloxacin (MAR) is a veterinary antimicrobial, marketed in injectable solution, oral suspension, and tablets. MAR has no monograph for tablet evaluation in official compendiums. High Performance Liquid Chromatography (HPLC) methods present in the literature for evaluating MAR in tablets do not follow the principles of green and sustainable analytical chemistry.

Objective: A green, clean, and sustainable method by HPLC was developed and validated to evaluate the content and stability of MAR in tablets, in addition to comparing it with other methods available in the literature.

Method: A C8, 5 µm, 4.6 × 150 mm (ACE®) column, purified water with 0.2% formic acid-ethanol (70:30, v/v) as the mobile phase, and a flow rate of 0.7 mL/min at 296 nm were used.

Results: The method was linear over a concentration range of 1-10 μg/mL, selective for tablet matrix and forced degradation, precise with relative standard deviations (RDS) less than 5%, accurate with recovery of 99.99%, and robust to changes in the mobile phase, flow rate, wavelength, equipment, and column brand. The retention time for MAR was approximately 3.1 min.

Conclusions: The method can be used in routine analysis of MAR in tablets in chemical-pharmaceutical laboratories. Furthermore, it can be used to verify the stability of MAR-based products and proved to be interchangeable with spectrophotometric method in the UV region and turbidimetric microbiological method.

Highlights: A green method for evaluation of marbofloxacin tablets by HPLC was developed and validated. Additionally, it has been shown to be interchangeable with UV and turbidimetric methods.

背景:马波沙星(MAR)是一种兽医抗菌药物,以注射溶液、口服混悬液和片剂的形式上市。MAR在官方汇编中没有关于片剂评价的专著。文献中用于评估片剂中MAR的高效液相色谱(HPLC)方法不符合绿色和可持续分析化学的原则。目的:建立并验证了一种绿色、清洁、可持续的高效液相色谱法来评价MAR在片剂中的含量和稳定性,并与文献中的其他方法进行了比较。方法:A C8,5 µm,4.6×150 mm(ACE®)柱,流动相为0.2%甲酸乙醇(70:30,v/v)的纯化水,流速为0.7 296时为mL/min nm。结果:该方法在1-10的浓度范围内呈线性 μg/mL,对片剂基质和强制降解具有选择性,精密度相对标准偏差(RDS)小于5%,准确度回收率为99.99%,对流动相、流速、波长、设备和柱品牌的变化具有鲁棒性。MAR的保留时间约为3.1 结论:该方法可用于化学制药实验室片剂中MAR的常规分析。此外,它可用于验证MAR基产品的稳定性,并被证明可与紫外区域的分光光度法和浊度微生物法互换。亮点:建立并验证了高效液相色谱法评价马波沙星片的绿色方法。此外,它已被证明可以与紫外线和浊度法互换。

Background: Rifaximin, a medication of the rifamycin family with two distinct strengths of 200 mg and 550 mg in tablet form, is useful for the treatment of travelers' diarrhea. It has a solid yellow hue and is very hygroscopic in nature. It exhibits a variety of polymorphic forms such as α, β, γ, δ, and ε depending on bonded moisture. These polymorphs' varying chemical and physical characteristics, such as solubility and water content, may have a big impact on in vivo absorption, which in turn affects efficacy and safety. Therefore, understanding the polymorphic stability of rifaximin is crucial for formulating rifaximin tablets.

Objective: The current effort focuses on the understanding of water vapor sorption properties to control the polymorphic stability of rifaximin in the tablet formulation using the appropriate selection of excipients and manufacturing process.

Methods: The dynamic vapor sorption method in the range of 0-90% relative humidity at 25°C is used for understanding the sorption properties of drug substances and drug excipient mixtures; the state-of-the-art techniques of the X-ray diffraction method are used to identify polymorph conversions; and dissolution procedures are used for in vitro correlation studies.

Results: The sorption study data reveals that rifaximin is highly unstable at relative humidity conditions above 36%. When using excipients that have a low tendency to adsorb water in the formulation, the polymorphic results do not show any change in their intended form, and the in vitro dissolution data show an equivalency with the reference drug product.

Conclusion: The study prompted a successful outcome-oriented development of the formulation processing environment conditions design to develop a test formulation that has adequate polymorphic stability and also similarity in in-vitro dissolution profiles, with the reference product with highest similarity.

Highlights: The overall study described here is useful for swiftly gaining insight into the sorption characteristics of rifaximin, and it contributes to the widespread acceptance of rifaximin tablets as a treatment option.

背景:利福霉素家族的一种药物,具有两种不同的200 mg和550 片剂形式的mg可用于治疗旅行者腹泻。它有一个坚实的黄色色调,是非常吸湿性的性质。根据结合水分的不同,它表现出多种多晶型,如α、β、γ、δ和ε。这些多晶型物不同的化学和物理特性,如溶解度和含水量,可能会对体内吸收产生重大影响,进而影响疗效和安全性。因此,了解利福昔明的多态性稳定性对于配制利福昔敏片剂至关重要。目的:目前的工作重点是了解水蒸气吸附特性,通过适当选择辅料和生产工艺来控制利福昔明在片剂配方中的多态性稳定性。方法:采用25°C相对湿度0-90%范围内的动态气相吸附法,了解原料药和辅料混合物的吸附性能;使用X射线衍射方法的最先进技术来鉴定多晶型转化率;以及溶出程序用于体外相关性研究。结果:吸附研究数据表明,利福昔明在相对湿度超过36%的条件下是高度不稳定的。当使用制剂中吸水性低的赋形剂时,多晶型结果没有显示其预期形式的任何变化,体外溶出度数据显示与参考药物产品相当。结论:该研究促进了以结果为导向的制剂加工环境条件设计的成功开发,以开发一种具有足够多态性稳定性和体外溶出度相似性的试验制剂,与相似性最高的参考产品。亮点:本文所述的整体研究有助于迅速深入了解利福昔明的吸附特性,并有助于利福昔敏片作为一种治疗选择的广泛接受。

Background: Propylene chlorohydrins (PCHs) are formed as byproducts in the reaction between starch and propylene oxide (PO). For hydroxypropylated (HP) starch applications in food, Joint FAO/WHO Expert Committee on Food additives (JECFA) set the maximum allowed total propylene chlorohydrin (PHC-t) residues level at 1 mg/kg.

Objective: To develop an improved analytical method for the determination of the PCH-t content in starches in the low mg/kg range to replace the outdated JECFA method.

Methods: A new GC-MS method that utilizes aqueous methanol as extraction medium for PCH. The GC-MS system is equipped with a programmable temperature vaporization injector and Stabilwax-DA column and uses helium as carrier gas. Quantitative detection is achieved in selected ion monitoring mode.

Results: This single-laboratory validation (SLV) study showed good linear calibrations for both 1-chloro-2-propanol (PCH-1) and 2-chloro-1-propanol (PCH-2) in the concentration range of 0.5-4 mg/kg in dry starch. The lower LOQ of PCH-1 and PCH-2 was 0.2-0.3 mg/kg in dry starch, the reproducibility RSD (RSDR) at the concentration level of 1-2 mg/kg in dry starch was 3-5%, and the recovery values for both PCH-1 and PCH-2 were in the range of 78-112% at a concentration level of about 0.6 mg/kg in dry starch. Compared with the current, outdated JECFA method, the new GC-MS method is more sustainable, less laborious, and therefore more economical. The analytical capacity of the new method is 4-5 times higher than the analytical capacity of the old JECFA method.

Conclusion: The GC-MS method is fit for a multi-laboratory trial (MLT).

Highlights: Based on the results of this SLV and the MLT (will be published in a second paper), the Joint FAO/WHO Expert Committee on Food Additives has recently decided to replace the outdated GC-FID JECFA method with the new GC-MS method for the determination of PCH-t content in starches.

背景:丙二氯丙烷(PCHs)是淀粉和环氧丙烷(PO)反应的副产物。对于在食品中应用的羟丙基化(HP)淀粉,粮农组织/世卫组织食品添加剂联合专家委员会(JECFA)将丙烯-氯丙烷(PHC-t)的最大允许残留量定为每公斤1毫克。目的:建立一种改进的低mg/kg范围内测定淀粉中PCH-t含量的分析方法,以取代过时的JECFA法。方法:采用气相色谱-质谱联用技术,以甲醇水溶液为提取介质提取PCH。GC-MS系统配备可编程温度汽化注射器和Stabilwax-DA柱,并使用氦气作为载气。定量检测在选定的离子监测模式下实现。结果:在0.5 ~ 4mg /kg的浓度范围内,对干淀粉中1-氯-2-丙醇(PCH-1)和2-氯-1-丙醇(PCH-2)均具有良好的线性校准效果。PCH-1和PCH-2在干淀粉中的下限限为0.2 ~ 0.3 mg/kg, 1 ~ 2 mg/kg干淀粉浓度下的重复性RSD (RSDR)为3 ~ 5%,在约0.6 mg/kg干淀粉浓度下,PCH-1和PCH-2的回收率在78 ~ 112%之间。与目前过时的JECFA方法相比,新的GC-MS方法更具可持续性,更省力,因此更经济。新方法的分析能力是旧方法的4-5倍。结论:气相色谱-质谱法适用于多实验室试验。根据SLV和MLT的结果(将在第二篇论文中发表),粮农组织/世卫组织食品添加剂联合专家委员会最近决定用新的GC-MS方法取代过时的GC-FID JECFA方法来测定淀粉中PCH-t的含量。

Background: Peramivir is a neuraminidase inhibitor that serves as a transition state analogue for influenza neuraminidase, inhibiting the formation of new viruses in infected cells, and has been approved for intravenous administration.

Objective: To validate an HPLC method used to identify the degraded products of the antiviral drug peramivir.

Methods: Herein, we report the identification of compounds formed after the degradation of peramivir through acid, alkali, peroxide, thermal, and photolytic degradation. At the level of toxicology, a technique was devised for the isolation and measurement of peramivir.

Results: A sensitive and reliable LC-tandem mass spectrometry technique for the quantitative measurement of Peramivir and its impurities was developed and verified in order to comply with the recommendations made by the International Council for Harmonisation (ICH). The proposed protocol was in the 50-750 µg/mL range. Relative Standard Deviation values of less than 2.0% indicated good recovery in the range of 98.36-102.57%. Within the studied range, the calibration curves demonstrated good linearity and, in addition, the fitting of correlation coefficient was more than 0.999 for every impurity. Quantitative analysis of contaminants revealed the high efficiency at a low level.

Conclusion: Given its ability to separate degradation products, quantitative analysis is used to detect and quantify known and unknown impurities and degradants in the peramivir drug substance during routine analysis and stability studies. No significant degradation was found in peroxide and photolytic degradation studies.

Highlights: An HPLC method was developed and put to the test in order to analyze the behavior of the impurities of peramivir as they degraded when subjected to the stress conditions suggested by the ICH. Peramivir was found to be stable under peroxide and photolysis conditions but not stable or degradable when exposed to the acid, base, and thermal stress conditions. The method developed was extremely precise, linear, accurate, robust, and rugged. As a result, this technology has the potential to be used in the medication production process for regular impurity analysis as well as for the stability analysis of peramivir.

背景:Peramivir是一种神经氨酸酶抑制剂,作为流感神经氨酸酶的过渡状态类似物,抑制感染细胞中新病毒的形成,已被批准用于静脉注射。目的:建立高效液相色谱法鉴别抗病毒药物帕拉米韦降解产物的方法。方法:本文报道了帕拉米韦经酸、碱、过氧化物、热和光解降解后形成的化合物的鉴定。在毒理学水平上,设计了一种分离和测定帕拉米韦的技术。结果:建立了一种灵敏可靠的液相色谱-串联质谱法定量测定帕拉米韦及其杂质的方法,并经验证符合国际协调理事会(ICH)的建议。提议的方案在50-750µg/mL范围内。相对标准偏差小于2.0%,回收率为98.36 ~ 102.57%。在研究范围内,各杂质的线性关系良好,相关系数均在0.999以上。污染物的定量分析表明,该方法在低水平下效率高。结论:鉴于其降解产物的分离能力,在常规分析和稳定性研究中,定量分析可用于检测和定量帕拉米韦原料药中已知和未知的杂质和降解物。在过氧化和光解降解研究中没有发现明显的降解。重点:建立了高效液相色谱法,并进行了测试,以分析帕拉米韦中杂质在ICH建议的应激条件下降解的行为。Peramivir在过氧化和光解条件下是稳定的,但在酸、碱和热应力条件下不稳定或可降解。所开发的方法非常精确,线性,准确,坚固耐用。因此,该技术有潜力用于药物生产过程中的常规杂质分析以及帕拉米韦的稳定性分析。

Background: The replacement of traditional oils with a camphor and menthol-based eutectic mixture is done to prepare oil-less emulsion-like dispersions for co-delivery of cinnarizine (CNZ) and morin hydrate (MH) for managing Meniére's disease (MD). Since two drugs are loaded into the dispersions, the development of a suitable reverse phase-high performance liquid chromatography (RP-HPLC) method for their simultaneous analysis becomes inevitable.

Objective: By applying the analytical quality by design (AQbD) approach, the RP-HPLC method conditions were optimized for the concomitant determination of two drugs.

Methods: The systematic AQbD started with identifying critical method attributes (CMA) through an Ishikawa fishbone diagram, risk estimation matrix, and risk priority number-based failure mode effect analysis followed by screening using fractional factorial design and optimization by face-centered central composite design. The concomitant determination of two drugs by the optimized RP-HPLC method condition was substantiated via specificity checking using combined drug solution, drug entrapment efficiency, and in vitro release of the two drugs from emulsion-like dispersions.

Results: The AQbD optimized RP-HPLC method conditions revealed the retention time for CNZ and MH at 5.017 and 5.323, respectively. The studied validation parameters were found within the ICH-prescribed limits. Exposing the individual drug solutions to acidic and basic hydrolytic conditions yielded extra chromatographic peaks for MH, probably due to the degradation of MH. The DEE % values of 87.40 ± 4.70 and 74.79 ± 2.94, respectively, were noticed for CNZ and MH in emulsion-like dispersions. More than 98% CNZ and MH release was occurred from emulsion-like dispersions within 30 min post-dissolution in artificial perilymph.

Conclusions: Overall, the AQbD approach could be helpful for systematic optimization of RP-HPLC method conditions to estimate concomitantly other therapeutic moieties.

Highlights: The proposed article shows the successful application of AQbD for the optimization of RP-HPLC method conditions to concomitantly estimate CNZ and MH in combined drug solution and dual-drug-loaded emulsion-like dispersions.

背景:以樟脑和薄荷醇为基础的共晶混合物取代传统油,制备无油乳剂状分散体,用于联合递送肉桂嗪(CNZ)和水合桑胺(MH),以治疗menisamure病(MD)。由于两种药物被装载到分散体中,因此开发一种合适的反相高效液相色谱(RP-HPLC)方法来同时分析它们就成为必然。目的:采用设计质量法(AQbD),优化两种药物同时测定的反相高效液相色谱法条件。方法:系统AQbD首先通过石川鱼骨图、风险估计矩阵和基于风险优先级数的失效模式效应分析识别关键方法属性(CMA),然后采用分数析因设计进行筛选,再采用面心中心复合设计进行优化。通过联合药液的特异性检查、药物包封效率检查和两种药物在乳状分散体中的体外释放度检查,验证了优化后的反相高效液相色谱法条件下两种药物的同时测定。结果:AQbD优化的反相高效液相色谱法条件下,CNZ和MH的保留时间分别为5.017和5.323。所研究的验证参数均在ich规定的限度内。将单个药物溶液暴露于酸性和碱性水解条件下,可能是由于MH的降解,产生了额外的MH色谱峰。在乳状分散体中,CNZ和MH的DEE %分别为87.40±4.70和74.79±2.94。乳状分散体在人工淋巴周围溶出后30 min内释放出98%以上的CNZ和MH。结论:总体而言,AQbD方法有助于系统优化RP-HPLC方法条件,以估计伴随的其他治疗成分。重点:本文成功应用AQbD优化RP-HPLC法同时测定复方药物溶液和双载乳状分散体中CNZ和MH的条件。

Background: Atractylodes chinensis (DC.) Koidz. (A. chinensis) is a perennial herbaceous plant that is widely used as a Chinese medicine herb for gastric diseases. However, the bioactive compounds of this herbal medicine have not been defined, and quality control is imperfect.

Objective: Although the method of quality evaluation method for A. chinensis by high-performance liquid chromatography (HPLC) fingerprinting has been reported in related papers, it remains unknown whether the chemical markers selected are representative of their clinical efficacy. To develop methods for qualitative analysis and improved quality evaluation of A. chinensis.

Method: In this study, HPLC was used to establish fingerprints and conduct similarity evaluation. Principal component analysis (PCA) and orthogonal partial least squares discriminant analysis (OPLS-DA) were used to reveal the differences of these fingerprints. Network pharmacology was used to analyze the corresponding targets of the active ingredients. Meantime, an active ingredient-target-pathway network was constructed to investigate the characteristics of the medical efficacy of A. chinensis and to predict potential Q-markers.

Results: Combining network pharmacological effectiveness and composition specificity with the Q-marker concept, atractylodin (ATD), β-eudesmol, atractylenolide Ι (AT-I) and atractylenolide III (AT-III) were predicted to be potential Q-markers of A. chinensis that showed anti-inflammatory, antidepressant, anti-gastric, and antiviral effects by acting on 10 core targets and 20 key pathways.

Conclusions: The HPLC fingerprinting method established in this study is straightforward, and the identified four active constituents can be used as Q-markers of A. chinensis. These findings facilitate effective quality evaluation of A. chinensis and suggest this approach could be applied to evaluate the quality of other herbal medicines.

Highlights: The fingerprints of Atractylodis rhizoma were organically combined with network pharmacology to further clarify its criteria for quality control.

背景:苍术(Atractylodes chinensis)Koidz。(a . chinensis)是一种多年生草本植物,被广泛用作治疗胃病的中药。然而,该草药的生物活性成分尚未确定,质量控制也不完善。目的:虽然已有相关文献报道了高效液相色谱(HPLC)指纹图谱质量评价方法,但所选择的化学标记物是否能代表其临床疗效尚不清楚。目的:建立羊草的定性分析方法和改进的质量评价方法。方法:采用高效液相色谱法建立指纹图谱并进行相似度评价。采用主成分分析(PCA)和正交偏最小二乘判别分析(OPLS-DA)分析指纹图谱的差异。采用网络药理学方法对活性成分对应靶点进行分析。同时,通过构建有效成分-靶点-通路网络,探讨五倍子药用功效的特点,预测潜在的q -marker。结果:结合网络药理有效性和成分特异性,结合Q-marker概念,预测白术素(ATD)、β-苦参酚(β-eudesmol)、白术内酯Ι (AT-I)和白术内酯III (AT-III)通过作用于10个核心靶点和20个关键通路,具有抗炎、抗抑郁、抗胃和抗病毒的潜在Q-marker作用。结论:本研究建立的高效液相色谱指纹图谱方法简便,鉴定出的4种有效成分可作为羊草的q标记。本研究结果可为五倍子药材质量评价提供有效依据,并为其他药材质量评价提供参考。重点:将苍术的指纹图谱与网络药理学有机结合,进一步明确了苍术的质量控制标准。

Background: Despite the broad adoption of Soleris® technology in the food industry as semiquantitative method, it is almost completely unexplored in the pharmaceutical industry as a quantitative method for quantification of Burkholderia cepacia complex (Bcc).

Objective: The efficacy of an automated growth-based system for a quantitative determination of the Bcc in an antacid oral suspension was studied. The main purpose of this validation study was to prove that the alternative method's entire performance is not inferior to the conventional method for a quantitative determination of Bcc.

Method: The antacid oral suspension's preservatives were neutralized, leading to the Burkholderia complex's recovery by means of the alternative method and the reference method. A calibration curve was generated for each strain by plotting DTs relative to the corresponding log CFU values. An equivalence of results was done through the construction of calibration curves that allowed the establishment of numerically equivalent results between the enumeration data from the reference method and the alternative method.

Results: Thus following the guidelines of USP, essential validation parameters were shown, such as equivalence of results (CC >0.95), linearity (R2 >0.9025), accuracy (% recovery >70%), operating range, precision and ruggedness (DS <5 and CV <35%), specificity (inclusivity and exclusivity), limit of detection (LOD), and limit of quantification (LOQ).

Conclusions: It was shown that all the test results obtained from the alternative method were in statistical agreement with the standard method. Thus this new technology was found to meet all the validation criteria needed to be considered as an alternative method for the quantification of the Burkholderia complex in the antacid oral suspension tested.

Highlights: As outlined in USP chapter <1223> and demonstrated in this research the implementation of alternative methods can offer benefits in execution and automation while improving accuracy, sensitivity, and precision and can reduce the microbiological process time compared to the traditional ones.

背景:尽管Soleris技术作为半定量方法在食品工业中被广泛采用,但在制药工业中,作为洋葱伯克霍尔德菌复合体(Bcc)的定量方法,它几乎完全没有被探索过。目的:研究基于生长的自动系统定量测定抗酸口服混悬液中Bcc的效果。本验证研究的主要目的是证明替代方法的整体性能不低于常规方法用于Bcc的定量测定。方法:采用替代法和参比法对抗酸口服混悬液中的防腐剂进行中和,使伯克霍尔德菌复体恢复。通过绘制dt相对于相应的对数CFU值生成每个应变的校准曲线。通过建立校准曲线,使参考方法和备选方法的枚举数据在数值上等效。结果:在USP的指导下,给出了基本的验证参数,如结果的等效性(CC >0.95)、线性度(R2 >0.9025)、准确度(回收率>70%)、工作范围、精密度和坚固性(DS)。结论:替代方法得到的所有试验结果与标准方法在统计学上一致。因此,这项新技术被发现满足所有的验证标准,需要考虑作为一种替代方法,定量伯克霍尔德菌复合体在抗酸口服混悬液测试。要点:正如USP章节所概述的和本研究中所展示的,替代方法的实施可以在执行和自动化方面提供好处,同时提高准确性,灵敏度和精度,并且与传统方法相比可以减少微生物处理时间。

Background: The CompactDry "Nissui" BC is a ready-to-use dry media sheet using a chromogenic medium with selective agents for the detection and enumeration of Bacillus cereus in products after incubation at 30 ± 1°C for 24 ± 2 h.

Objective: The CompactDry "Nissui" BC method was validated to achieve AOAC Performance Tested MethodsSM certification.

Method: The performance of the CompactDry "Nissui" BC was compared to that of ISO 7932:2004 for 10 matrixes, including panna cotta, double cream, dried baby food, dried vegetable soup mix, seafood sticks, salmon pâté, sliced ham, pork liver pâté, ham and cheese sandwich, and Caesar pasta salad with chicken and bacon. Performance indicators included repeatability, difference of means (DOM), and inclusivity/exclusivity.

Results: After log10 transformation of the data, the relative standard deviation of repeatability (RSDr) was ≤9.2% for 28 of the 30 materials (10 matrixes each at three contamination levels) analyzed by the CompactDry "Nissui" BC method and ≤13% for 27 of the 30 matrix/level combinations analyzed by the reference method. Method equivalence was demonstrated in 28 of the 30 matrix/level combinations based on the 90% confidence interval of the DOM being within (-0.5, 0.5). For inclusivity, 47 of 50 strains tested showed typical colonies and confirmed positive. For exclusivity, 28 of 33 strains tested resulted in no growth or were negative, and five were positive. Inclusivity and exclusivity results were similar on the reference method agar. The method was shown to be robust to changes in sample volume, incubation temperature, and incubation time, and data are presented supporting product consistency and 18-month shelf life.

Conclusions: The CompactDry "Nissui" BC method is validated for the determination of Bacillus cereus in a variety of matrixes.

Highlights: The CompactDry "Nissui" BC method is equivalent to the ISO 7932:2004 reference method and is suitable for Performance Tested MethodsSM certification for the matrixes tested.

Background: Computationally designed molecular imprinted polymer (MIP) incorporation into electrochemical sensors has many advantages to the performance of the designed sensors. The innovative self-validated ensemble modeling (SVEM) approach is a smart machine learning-based (ML) technique that enables the design of more accurate predictive models using smaller data sets.

Objective: The novel SVEM experimental design methodology is exploited here exclusively to optimize the composition of four eco-friendly PVC membranes augmented by a computationally designed magnetic molecularly imprinted polymer to quantitatively determine drotaverine hydrochloride (DVN) in its combined dosage form and human plasma. Furthermore, the application of hybrid computational simulations such as molecular dynamics and quantum mechanical calculations (MD/QM) is a time-saving and eco-friendly provider for the tailored design of the MIP particles.

Method: Here, for the first time, the predictive power of ML is assembled with computational simulations to develop four PVC-based sensors decorated by computationally designed MIP particles using four different experimental designs known as central composite, SVEM-LASSO, SVEM-FWD, and SVEM-PFWD. The pioneering AGREE approach further assessed the greenness of the analytical methods, proving their eco-friendliness.

Results: The proposed sensors showed decent Nernstian responses toward DVN in the range of 58.60-59.09 mV/decade with a linear quantitative range of 1 × 10-7 - 1 × 10-2 M and limits of detection in the range of 9.55 × 10-8 to 7.08 × 10-8 M. Moreover, the proposed sensors showed ultimate eco-friendliness and selectivity for their target in its combined dosage form and spiked human plasma.

Conclusions: The proposed sensors were validated in accordance with International Union of Pure and Applied Chemistry (IUPAC) recommendations, proving their sensitivity and selectivity for drotaverine determination in dosage form and human plasma.

Highlights: This work presents the first ever application of both the innovative SVEM designs and MD/QM simulations in the optimization and fabrication of drotaverine-sensitive and selective MIP-decorated PVC sensors.

背景:计算设计的分子印迹聚合物(MIP)结合到电化学传感器中,对设计的传感器性能有许多优点。创新的自我验证集成建模(SVEM)方法是一种基于智能机器学习(ML)的技术,可以使用更小的数据集设计更准确的预测模型。目的:利用新型SVEM实验设计方法,优化四种环保PVC膜的组成,通过计算设计磁性分子印迹聚合物增强,定量测定盐酸曲维林(DVN)的联合剂型和人血浆。此外,混合计算模拟的应用,如分子动力学和量子力学计算(MD/QM),为MIP粒子的定制设计提供了节省时间和环保的服务。方法:本文首次将机器学习的预测能力与计算模拟相结合,采用四种不同的实验设计,即中心复合、svm - lasso、svm - fwd和svm - pfwd,开发了四种基于pvc的传感器,这些传感器由计算设计的MIP颗粒装饰。开创性的AGREE方法进一步评估了分析方法的绿色程度,证明了它们的生态友好性。结果:该传感器对DVN在58.60 ~ 59.09 mV/ 10年范围内表现出良好的Nernstian反应,线性定量范围为1 × 10-7 ~ 1 × 10-2 M,检出限为9.55 × 10-8 ~ 7.08 × 10-8 M。此外,该传感器在其联合剂型和加标血浆中对靶标具有良好的生态友好性和选择性。结论:该传感器符合国际纯粹与应用化学联合会(IUPAC)推荐标准,对盐酸曲维林剂型和人血浆中盐酸曲维林的检测具有较高的灵敏度和选择性。这项工作首次提出了创新的SVEM设计和MD/QM模拟在优化和制造盐酸敏感和选择性mip装饰PVC传感器中的应用。
