“…The coexistence of CNT and conducting polymers provides the fabrication of new multifunctional and active surfaces towards different analytes . This type of composites can be constructed with various polymers such as; 3‐methylthiophene , poly(methylene green) ,poly(aniline) , poly(glutamic acid) , poly(crystal violet) , poly(L‐aspartic acid) , poly(brilliant green) and poly(thionine) . On the other hand, co‐glutathione‐taurine combined CNT composites will be proposed as a novel electrode surface for the first time in this study.…”

A new highly sensitive and selective electrochemical levofloxacin sensor based on co‐polymer‐carbon nanotube composite electrode was developed. Taurine and Glutathione were electrochemically co‐polymerized on multiwalled carbon nanotubes modified glassy carbon electrode (Poly(TAU‐GSH)/CNT/GCE) and used as a levofloxacin sensor in pH 6 phosphate buffer solution. The new composite electrode surfaces were characterized by scanning electron microscopy, atomic force microscopy and electrochemical impedance spectroscopy. Under the optimized conditions, two linear segments were obtained for increasing LEV concentrations between 20 nmol L−1‐1 μmol L−1 and 1.5 μmol L−1‐55 μmol L−1 LEV with a detection limit of 9 nmol L−1 using amperometry. Poly(TAU‐GSH)/CNT/GCE exhibited high sensitivity, selectivity with good stability. The new sensor was employed for real samples of LEV tablets and urine. Promising results were obtained with good accuracy which were also in accordance with LC‐MS/MS analysis.

“…1,8 Several methods have been reported, suggesting separation of β 2 -Agonist compounds by using different analytical methods for the determination of β 2 -Agonists from biological fluids such as Liquid Chromatography-Mass Spectrometry (LC-MS), 1,2,9,10 Gas Chromatography-Mass Spectrometry (GC-MS) 11,12 and flow injection analysis coupled with electro generated chemiluminescence (FIA-ECL). 13 Moreover, the procaterol is metabolized into two metabolites (DM-251 and DM-252) along with the parent drug. However, the metabolites are only measurable up to 12 hr after administration, whereas unchanged procaterol is detectable up to 24 hr after administration.…”

Background: A simple, sensitive and accurate method for the determination of procaterol in human urine was developed and validated using Gas Chromatography coupled to tandem mass spectrometry (GC-MS/MS) as per the requirements of World Anti-Doping Agency (WADA) and ICH guidelines. Methodology: The sample processing includes deconjugation with enzymatic hydrolysis, Solid Phase Extraction (SPE) procedure using XAD2 column and Liquid-liquid Extraction (LLE) followed by the derivatisation using N-methyl trimethylsilysl trifluoroacetamide (MSTFA). Results: The method included a chromatographic run of 17 min and the calibration curve was linear over the concentration range of 5-40 ng/mL with a correlation coefficient (r) of 0.98. The intra-and inter-day assay precision ranged from 0.75 to 0.94% and 1.2 to 1.70%, respectively. The absolute recovery percentage for procaterol was found to be 83%. The recovery was sufficient to reliable identify the procaterol at or below the level prescribed by WADA ie MRPL 20ng/ ml. The LOQ and LOD was found to be 5 and 3 ng/ml respectively. Conclusion: A simple and sensitive GC-MS/MS method for quantitative estimation of Procaterol was developed and validated as per the WADA ISL and ICH guidelines. This developed method could be also used for therapeutic drug monitoring purposes.
