“…The effect of surfactants on the electrochemical process of analytes on BDDEs has been fruitfully explored along with electrochemical pretreatments, mostly by Yardim and collaborators, [234,240,243,265,[271][272][273][274][275][276] but also by others. [200,[277][278][279] Yardim et al [271] reported that the use of surfactants significantly enhanced the voltammetric response of an APT-BDDE (+ 1.30 V vs. Ag/AgCl (3 mol L À 1 NaCl)/30 s) for the polycyclic aromatic hydrocarbon benzo[a]pyrene; using SW-AdASV and the anionic surfactant sodium dodecylsulfate (SDS), this analyte was determined in the concentration range of 0.016-200 nmol L À 1 (LOD = 2.86 nmol L À 1 ) in a Britton-Robinson buffer, pH 2.0 con- APT or CPT conditions: + 0.5 A cm À 2 /30 s or À 0.5 A cm À 2 /120 s, in 0.5 mol L À 1 H 2 SO 4 .…”

The several outstanding properties of boron‐doped diamond electrodes (BDDEs) have allowed their application for various purposes, among them electrochemical sensing. However, the electrochemical response of many redox species on BDDEs can be strongly dependent on whether their surfaces are predominantly hydrogen‐ (HT) or oxygen‐terminated (OT). Fortuitously, electrochemical pretreatments themselves can be used to enrich in situ the BDEE surface in one or the other type of termination. The surface of a cathodically pretreated BBDE (CPT‐BDDE) becomes enriched in HTs, whereas that of an anodically pretreated BDDE (APT‐BDEE) becomes enriched in OTs. Thus, when suitable, the electrochemical activity of a BDDE for a given analyte may be tuned by electrochemical pretreatments, yielding enhanced sensing properties. The main purpose of this review is the compilation and discussion of papers published after 2009 reporting on electroanalytical applications based on a CPT‐BDDE or an APT‐BDDE. Procedures to perform proper electrochemical pretreatments are also discussed.

The present work describes the electroanalytical investigation and a novel voltammetric method for a cheap, fast and simple quantification of tramadol (TRH) using a boron-doped diamond (BDD) electrode. TRH displayed one well-defined, irreversible and adsorption-controlled oxidation peak at about +1.58 V (vs. Ag/AgCl) in Britton-Robinson buffer (BR, 0.1 mol L -1 , pH 3.0) using cyclic voltammetry (CV) technique. The voltammetric responses of the oxidation peaks are dependent on pH and its sensitivity was significantly enhanced in the existence of surfactant media (sodium dodecyl sulphate, SDS). In optimized experiment conditions, employing square-wave stripping mode, it was found that there was an excellent correlation between oxidation peak current and TRH concentration in the range of 0.25 to 50.0 μg mL -1 (8.34×10 -7 --1.67×10 -4 mol L -1 ), with a detection limit of 0.072 μg mL -1 (2.40×10 -7 mol L -1 ) in 0.1 mol L -1 BR buffer (pH 3.0) solution comprising 8×10 -4 mol L -1 SDS at +1.52 V (after 30 s accumulation at open-circuit condition). The developed approach can be used for the quantification of TRH in the pharmaceutical formulations and the spiked human urine samples with acceptable recoveries.

“…The quinoline ring is an essential structure for the antibacterial action of fluoroquinolones including enrofloxacin. 3,[6][7][8] Fluorine atom is a characteristic substituent of fluoroquinolones, which is on the C 6 position of the drug, that can enhance DNA gyrase affinity, 9 increase the permeability of the bacterial cell wall, and enhance the antibacterial effect against of G + bacteria such as Staphylococcus. The introduction of piperazinyl in the C 7 position of the drug, on the one hand, improved its antibacterial activity (such as anti-Pseudomonas aeruginosa activity) and its antibacterial spectrum, on the other hand, induced the production of side effects.…”

Introduction: Enrofloxacin is used in the treatment of a wide variety of bacterial infections in mammals. However, its poor solubility limits the clinical use. Methods: In order to improve the solubility of enrofloxacin, the enrofloxacin mesylate (EM) were obtained by a chemical synthesis method. The characterization of EM was carried out using ultraviolet scan (UV), synchronous thermal analysis (SDT), fourier transform infrared spectrometer (FTIR) and mass spectrometry (MS), nuclear magnetic resonance (NMR) and X-ray powder diffraction analysis (XRPD). Acute toxicity of EM in Kunming mice was studied. Besides, pharmacokinetic studies were performed in New Zealand rabbits at a single oral dose of 10 mg/kg, and the antibacterial activity of EM was also evaluated. Results: EM was successfully synthesized and purified. The stoichiometric ratio of mesylate to enrofloxacin was 1:1 and the aqueous solubility of EM was 483.01±4.06 mg/mL, the solubility of EM was about 2000 times higher than enrofloxacin. The oral lethal dose (LD 50 ) of EM was 1168.364 mg/kg, and the pharmacokinetics indicated that the oral relative bioavailability of EM was about 1.79 times and 1.48 times higher than that of enrofloxacin and enrofloxacin hydrochloride, respectively. In addition, the in vitro antibacterial activity of EM was not significantly changed compared with enrofloxacin and enrofloxacin hydrochloride. Conclusion: EM has higher solubility, low toxicity for oral use, and increases the oral bioavailability in rabbit. This study may be of benefit for the development of new enrofloxacin drugs.
