Estimation of Beta-Lactam Antibiotics-Serum Albumin Conjugated Proteins by High Performance Liquid Chromatography with Ultraviolet Detector
β-lactam antibiotics represented the oldest class of antibiotics used in the treatment of infections in a human being, livestock, and aquaculture. Drugs residues in the edible tissues or foodstuffs of animal pose a potential threat to human health. At present, extensive antibiotic-resistant strains are now being detected and the development of antibiotic-resistant strains of epidemic and zoonotic pathogens is a major concern. Therefore, the purpose of this study was to estimate the extent of β-lactam antibiotics-HSA/BSA conjugations via three conjugation methods by using high-performance liquid chromatography (HPLC) with ultraviolet (UV) detector. We wish that the technique will be applied to preliminarily detect the residues of β-lactam antibiotics may persist in edible tissues or foodstuffs in the livestock and aquaculture farms in clinical.
Relative Bioavailability of Ciprofloxacin Doses (750 and 1000) mg in Healthy Male Volunteers by Using HPLC Method
A new, stable and accurate high performance liquid chromatography ultraviolet spectrophotometric method for quantitation of Ciprofloxacin in human plasma was developed and validated.
Identification of Pyrrolidinophenone-type Designer Drugs by Gas Chromatography/ Time-of-Flight Mass Spectrometry
Use of gas chromatography (GC) combined with time-of –flight mass spectrometry (TOFMS) with soft ionization generated with three different plasma gases (i.e., Xe, Kr, Ar) was evaluated for the identification of several pyrrolidinophenone-type designer drugs that are commercially available.
The Ni(II) Complex of 2-Hydroxy-Pyridine-N-Oxide 2-Isothionate: Synthesis, Characterization, Biological Studies, and X-ray Crystal Structures using (1) Cu Kα Data and (2) Synchrotron Data
C12H20N6NiO6S2 or NiL2(SCN)2](NH4)2.2H2O, where L is 2-hydroxy-pyridine-N-oxide, has been prepared and characterized using elemental analyses, IR, UV and visible spectrometry, magnetic moment measurements, thermal analyses and single crystal X-ray analyis. The results indicate that the complex reacts as a bidentate ligand and is bound to the metal ion via the two oxygen atoms of the ligand (HL).
Identification of Designer Drugs using Gas Chromatography High-Resolution Mass Spectrometry and a Soft-Ionization Source
Gas chromatography-mass spectrometry (GC-MS) with electron ionization (EI) or chemical ionization (in positive or negative mode) plays an important role in the forensic analysis of designer drugs.
