“…Other methods concern electrochemical techniques, which are interesting for their rapidity, affordability and selectivity. In this area, LNZ was also the oxazolidinone object of most studies [ 21 , 43 , 44 , 45 , 46 , 47 ]. In [ 45 ], the electrochemistry of LNZ was investigated and a method based on differential pulse voltammetry (DPV) was developed for its quantification, using a glass carbon electrode.…”

“…The method was tested for the quantification of LNZ in pharmaceutical preparation and in urine, with LOD of 50 mg/L and linear response up to 200 mg/L. More recently, the use of new electrode materials, which is one of the main research topics in the field of electrochemistry, has led to the development of new methods [ 21 , 43 , 44 , 45 , 46 , 47 ]. The most recent are based on the use of graphene oxide–bentonite sodium composite modified electrodes [ 47 ], multiwalled carbon nanotubes modified carbon paste electrodes [ 43 , 46 ], unmodified renewable pencil graphite electrodes [ 44 ] or boron-doped diamond electrodes pretreated cathodically [ 21 ].…”

“…All were used for the detection of LNZ in pharmaceutical or biological samples, showing good performance concerning both linear concentration range and LOD. As an example, by using a boron-doped diamond electrode pretreated cathodically for LNZ determination in pharmaceutical formulations [ 21 ], calibration curves were linear over concentration ranges of 0.25–6.41 μg/mL, with LOD of 0.05 μg/mL. The best performance obtained by the different instrumental techniques are summarized in Table 2 .…”

“…Due to worrying growth around the world of bacterial resistance to antibiotics, their analytical determination in biological fluids has gained increasing interest. Analytical methods for oxazolidinone determination are also relevant for environmental applications, since antibiotics are released into natural waters and accumulate in the soil, threatening the health of living beings [ 21 ].…”

This review covers the main aspects concerning the chemistry, the biological activity and the analytical determination of oxazolidinones, the only new class of synthetic antibiotics advanced in clinical use over the past 50 years. They are characterized by a chemical structure including the oxazolidone ring with the S configuration of substituent at C5, the acylaminomethyl group linked to C5 and the N-aryl substituent. The synthesis of oxazolidinones has gained increasing interest due to their unique mechanism of action that assures high antibiotic efficiency and low susceptibility to resistance mechanisms. Here, the main features of oxazolidinone antibiotics licensed or under development, such as Linezolid, Sutezolid, Eperezolid, Radezolid, Contezolid, Posizolid, Tedizolid, Delpazolid and TBI-223, are discussed. As they are protein synthesis inhibitors active against a wide spectrum of multidrug-resistant Gram-positive bacteria, their biological activity is carefully analyzed, together with the drug delivery systems recently developed to overcome the poor oxazolidinone water solubility. Finally, the most employed analytical techniques for oxazolidinone determination in different matrices, such as biological fluids, tissues, drugs and natural waters, are reviewed. Most are based on HPLC (High Performance Liquid Chromatography) coupled with UV-Vis or mass spectrometer detectors, but, to a lesser extent are also based on spectrofluorimetry or voltammetry.

The electrochemical properties of ibrutinib (IBR), a new generation smart anti‐cancer drug, one of the Bruton's tyrosine kinase (BTK) inhibitors were investigated by a voltammetric method in the anionic surfactant (sodium dodecyl sulfate, SDS) medium with the boron‐doped diamond electrode (BDDE). IBR showed an oxidation step at about +1.56 V (vs Ag/AgCl (3.0 mol L−1 KCl) by cyclic voltammetry (CV) technique in 0.1 mol L−1 H2SO4 solution. IBR was found to be irreversible and diffusion‐controlled on the surface of the BDDE with studies of scan rate. The possible electrochemical oxidation reaction of IBR with the electroactive ring (pyrazole‐pyrimidine ring) in the structure of IBR is discussed. Square wave voltammetry (SWV) was preferred as the study method due to reproducibility for the determination of IBR in pharmaceutical and urine samples. At optimal values of SWV parameters, IBR showed good linearity in the concentration range of 0.01–2.00 μg mL−1 (5.7×10−8–2.3×10−6 mol L−1) in 0.1 mol L−1 H2SO4 with 6×10−4 M SDS. The detection (LOD) and quantification (LOQ) limits for IBR were set at 0.003 μg mL−1 (6.9×10−9 mol L−1) and 0.01 μg mL−1 (2.27×10−8 mol L−1), respectively. The relative standard deviation of the intra‐day and inter‐day repeatability of the proposed method was found 2.15 and 3.76, respectively. The necessary validation parameters have also been studied, and the recovery results obtained from both pharmaceutical dosage form and human urine samples show that the developed method is accurate and precise.

Dabrafenib (DAB) is an organofluor compound and a protein kinase inhibitor used as the mesylate salt in the treatment of metastatic melanoma. For the first time, the electrochemical investigation of the anticancer drug DAB in human serum was conducted using a glassy carbon electrode modified with multi‐walled carbon nanotubes (MWCNTs), employing cyclic voltammetry and square wave voltammetry (SWV) techniques. Electrochemical impedance spectroscopy, cyclic voltammetry, and scanning electron microscopy (SEM) techniques were utilized to analyze the surface morphology and structure of the MWCNT/GC electrode. In the proposed method using optimized experimental conditions, two different linearities were obtained for DAB in the concentration range of 0.04–0.8 μM and 1.0–10.0 μM. The LOD value obtained is 0.014 μM. In this study, the resulting electrochemical sensor was applied for the first time to investigate the electrochemical behavior of DAB with high sensitivity and reproducibility, as well as the possible electrochemical oxidation mechanism.
