A Novel high throughput 96-well based Fluorimetric Method to Measure Amikacin in Pharmaceutical Formulations: Development using Response Surface Methodology. LUMINESCENCE 2022; 37:930-943.

Abstract
An aminoglycoside antibiotic, amikacin, is used to treat severe and recurring bacterial infections. Due to the absence of a chromophore, however, amikacin must be extensively derivatized before being quantified, both in analytical and bioanalytical samples. In this study, for the first time, we developed a simple and sensitive method for measuring amikacin sulfate by spectrofluorimetry using a 96-well plate reader, based on the design of the experiment's approach. To develop a robust and reproducible spectrofluorimetric method, the influence of essential attributes, namely pH of the buffer, heating temperature, and concentration of reagents, were evaluated by univariate analysis followed by multivariate analysis (central composite design). ICH guidelines were used to validate the optimized method. The developed technique is linear from 1.9 to 10 μg/mL with a regression coefficient of 0.9991. The detection and quantification limits were 0.649 μg/mL and 1.9 μg/mL, respectively. For the developed method, both intra- and inter-day precision (%RSD) were below 5%. Using the method, amikacin concentrations were quantified in prepared amikacin liposomes and commercial formulations of Amicin®. The developed method greatly reduces sample volume and is a rapid, high throughput microplate-based fluorescence approach for the convenient and cost-effective measurement of amikacin in pharmaceutical formulations. In comparison to previously published approaches, the suggested method allowed for quick analysis of a high number of samples in a short amount of time (96 samples in 125 seconds), resulting in an average duration of analysis of 1.3 seconds per sample.

Abstract
Amikacin (AMK) is one of the commonly used aminoglycoside antibiotics, introduced for clinical use in patients suffering from bacterial infections especially life-threatening gram-negative infections. Due to lack of chromophore in the molecule, the detection of AMK during analysis is a challenge. Thus, pre and post-column derivatization techniques are generally used for AMK estimation. This review focuses on different analytical methods used for detection and quantification of AMK in pure or fixed dose combination pharmaceutical formulations and biological samples. Various reported methods described in the literature include high-performance liquid chromatography techniques, pulsed electrochemical detection techniques, Chemiluminescence techniques, Capillary electrophoresis and immunological methods. High-performance-liquid-chromatography based methods with UV/Vis spectrophotometric, fluorescence and mass spectrometric detection are the most prevailing methods employed for the analysis of AMK. This review could be of significant importance in the area of future AMK analytical method development studies.

Abstract
Background:
Amikacin sulfate (AMK) belongs to the class of aminoglycoside antibiotics. It
is effective against the infections caused by Gram-negative and positive bacteria. AMK lacks a chromophore
group in its structure and, therefore, it does not absorb light in the 200-800 nm region which
makes it a difficult molecule to analyze by UV detector using high performance liquid chromatography
(HPLC).
Objective:
This study has been carried out to develop and validate a relatively simple, accurate, precise,
rapid, economical, and stability-indicating pre-column derivatization HPLC method for the determination
of AMK in pure and parenteral dosage forms.
Methods:
The stock solution of AMK was derivatized prior to its analysis. The mobile phase used for
the analysis was acetonitrile and water in the ratio of 50:50 (v/v) at pH 6.0. The method has been validated
according to the guideline of International Council for Harmonization (ICH) and different parameters
such as linearity, range, accuracy, precision, sensitivity, robustness, solution stability, specificity
and system suitability have been studied. AMK was subjected to stress degradation studies including
thermolysis, humidity exposure, acid-base hydrolysis, and oxidation in order to determine the specificity
of the test method.
Results:
The retention time of AMK has been found to be 4.7 min. The results indicated that the method
is linear in the concentration range of 12.5-125% and possesses high accuracy (99.88±0.42%), precision
((<1.2%) and robustness (<0.5%). The obtained results are compared statistically with a reference
method.
Conclusion:
It was observed that the stress degradation studies do not affect the accuracy of the
method. Hence the proposed method can be used for the assay of AMK and its parenteral dosage form.

Abstract
This work presents a rapid and sensitive high performance liquid chromatography method for the determination of amikacin in water samples with solid phase extraction and pre-column derivatization. Amikacin residue was extracted from water samples with solid phase extraction cartridge. Then the extraction solution was derivatized with 4-chloro-3,5-dinitrobenzotrifluoride in the presence of triethylamine at 70°C in 20 min. The amikacin derivative was separated on a C18 column and detected by application of UV detection at 238 nm. The limit of detection is 0.2 μg/L with a signal-to-noise ratio of 3 and linearity is established over the concentration range from 0 to 500.0 μg/L. Recoveries of the amikacin in three types of water samples are from 87.5 % to 99.6 % and RSDs are 2.1 %-4.5 %. This method can be used for the quantification of amikacin residues in water samples.

Abstract
Neuroprotective controlled therapeutic hypothermia is the standard of care for newborns suffering perinatal asphyxia. Antibiotic drugs, such as amikacin, gentamicin, and vancomycin are frequently administered during controlled hypothermia, which possibly alters their pharmacokinetic (PK) and pharmacodynamic (PD) profiles. In order to examine this effect an LC-MS/MS method for the simultaneous quantification of amikacin, the major gentamicin components (gentamicin C, C1a and C2), and vancomycin in plasma was developed. In 25μL plasma proteins were precipitated with trichloroacetic acid (TCA) and detection of the components was achieved using ion-pair reversed phase chromatography coupled with electrospray ionization tandem mass spectrometry. The chromatographic runtime was 7.5min per sample. Calibration standards were prepared over a range of 0.3-50mgL(-1) for amikacin and gentamicin and 1.0-100mgL(-1) for vancomycin. At LLOQ accuracy was between 103 and 120% and imprecision was less than 19%. For concentrations above LLOQ accuracy ranged from 98% to 102% and imprecision was less than 6%. Process efficiency, ionization efficiency, and recovery were acceptable. Samples and stock solutions were stable during the time periods and at the different temperatures examined. The applicability of the method was shown by analysing plasma samples from 3 neonatal patients. The developed method allows accurate and precise simultaneous quantification of amikacin, gentamicin, and vancomycin in a small volume (25μL) of plasma.

Abstract
The quantitative estimation of amikacin (AMK) in AMK sulfate injection samples is reported using FTIR-derivative spectrometric method in a continuous flow system. Fourier transform of mid-IR spectra were recorded without any sample pretreatment. A good linear calibration (r>0.999, %RSD<2.0) in the range of 7.7–77.0 mg/mL was found. The results showed a good correlation with the manufacturer's and overall they all fell within acceptable limits of most pharmacopoeial monographs on AMK sulfate.

Abstract
In recent years, the use and number of biotherapeutics has increased significantly. For these largely protein-based therapies, the quantitation of aggregates is of particular concern given their potential effect on efficacy and immunogenicity. This need has renewed interest in size-exclusion chromatography (SEC). In the following review we will outline the history and background of SEC for the analysis of proteins. We will also discuss the instrumentation for these analyses, including the use of different types of detectors. Method development for protein analysis by SEC will also be outlined, including the effect of mobile phase and column parameters (column length, pore size). We will also review some of the applications of this mode of separation that are of particular importance to protein biopharmaceutical development and highlight some considerations in their implementation.

Abstract
A novel analytical method based on laser desorption postionization mass spectrometry (LDPI-MS) was developed to investigate the competence and sporulation factor-a pentapeptide of amino acid sequence ERGMT-within intact Bacillus subtilis biofilms. Derivatization of the neat ERGMT peptide with quinoline- and anthracene-based tags was separately used to lower the peptide ionization potential and permit direct ionization by 7.87-eV vacuum ultraviolet radiation. The techniques of mass shifting and selective ionization of the derivatized peptide were combined here to permit detection of ERGMT peptide within intact biofilms by LDPI-MS, without any prior extraction or chromatographic separation. Finally, imaging MS specific to the derivatized peptide was demonstrated on an intact biofilm using LDPI-MS. The presence of ERGMT in the biofilms was verified by bulk extraction/LC-MS. However, MALDI imaging MS analyses were unable to detect ERGMT within intact biofilms.

Abstract
A two-step gradient liquid chromatographic method combined with pulsed electrochemical detection is described for the determination of amikacin and its impurities. The mobile phase is composed of an aqueous solution containing 1.8 g/l sodium 1-octanesulphonate, 14 ml/l tetrahydrofuran, 50 ml/l of phosphate buffer pH 3.0 and sodium sulphate, which was 20 g/l in mobile phase A and 28 g/l in mobile phase B. 0.5 M sodium hydroxide was added post-column to enhance the detection. An investigation of different reversed-phase columns indicated that the Discovery (C18, 5 microm, 250 mm x 4.6 mm i.d.) column was the most suitable. Compared to previously published investigations, the proposed method showed higher sensitivity and efficiency, allowing the separation of the main component amikacin from 16 impurities, 7 of which were of unknown identity. A central composite experimental design was used to assess the robustness. The method showed good repeatability and linearity in the assay range. The method was further applied to analyze some commercial samples.

Abstract
A simple and sensitive method was developed for the quantification of amikacin in human plasma and urine samples. The method involves centrifugation of body fluid plasma after dilution with an ethanol/sodium carbonate mixture, and then an aliquot of the supernatant is directly injected into the chromatograph. After separation on a reversed-phase C18 column (runtime 20 min), aminoglycoside is detected on the basis of its complex formation reaction with Cu(II), the catalyst of the luminol/hydrogen peroxide chemiluminescence system. Using a volume of 500 microl biological sample, linearity is established over the concentration range 0.15-2.0 microg/ml and the limit of detection (LOD) is ca. 50 microg/l in plasma or urine. The intra-day and inter-day precision (measured by relative standard deviation, R.S.D.%) are always less than 9%, and relative recoveries are found to be over 92%.
