AbstractThe metabolic transformation pathways of the 1,4-benzodiazepine tetrazepam (C16H17ClN2O, average mass: 288.772) were studied with capillary LC-QqTOF-MS and -MS/MS by analyzing human plasma and urine samples collected from healthy volunteers. Each volunteer took 50 mg of tetrazepam, given in the form of one tablet of Myolastan (Sanofi-Synthelabo, Vienna, Austria). Accurate molecular mass measurements in full-scan mode (scan range: 50–700) were used to survey the collected samples for…

Reduction of temazepam to diazepam and lorazepam to delorazepam during enzymatic hydrolysis
TLDR
It is reported that this unusual reductive transformation of urinary oxazepam by commercial β-glucuronidase enzyme preparations, from Escherichia coli, Helix pomatia and Patella vulgata, results in production of nordiazepam (desmethyldiazepam) artefact.
Metabolic studies of tetrazepam based on electrochemical simulation in comparison to in vivo and in vitro methods.
TLDR
The present study demonstrates that this metabolic conversion of tetrazepam can also be predicted on the basis of a purely instrumental method, consisting of an electrochemical cell coupled to online liquid chromatography (LC) and mass spectrometry (MS).
Evaluation of the performance of a tandem mass spectral library with mass spectral data extracted from literature.
TLDR
The overall sensitivity of library search was found to be 96.4%, which clearly proves that the MSforID library can successfully handle data from a huge variety of mass spectrometric instruments to allow accurate compound identification.
An optimized electrochemistry-liquid chromatography-mass spectrometry method for studying guanosine oxidation
TLDR
The combination of electrochemistry/liquid chromatography/mass spectrometry (EC/LC/MS) is presented as convenient, fast and simple method to study nucleic acids oxidation to resolve isobaric oxidation products.
Quality evaluation of tandem mass spectral libraries
TLDR
Only the MSforID library was shown to be efficiently transferable to different kinds of tandem mass spectrometers, including “tandem-in-time” instruments; this is due to the coverage of a large range of different collision energy settings—including the very low range—which is an outstanding characteristics of the MS forID library.

A Derivative Method with Free Radical Oxidation to Predict Resveratrol Metabolites by Tandem Mass Spectrometry
TLDR
An oxidative method with free radical to generate 3,5,4′-trihydroxy-trans-stilbene (trans-resveratrol) metabolites and detect sequentially by an autosampler coupling with liquid chromatography electrospray ionization tandem mass spectrometer (LC-ESI–MS/MS).
Applying Tandem Mass Spectral Libraries for Solving the Critical Assessment of Small Molecule Identification (CASMI) LC/MS Challenge 2012
TLDR
T tandem mass spectral library search was applied to solve Category 2 of the CASMI Challenge 2012 (best identification for high resolution LC/MS data), and in the absence of any reference spectrum, a false positive identification was obtained for 1-aminoanthraquinone.
Detection and identification of drugs and toxicants in human body fluids by liquid chromatography-tandem mass spectrometry under data-dependent acquisition control and automated database search.
Ascorbic acid for homogenous redox buffering in electrospray ionization–mass spectrometry
TLDR
Ascorbic acid offered superior antioxidant activity, a relatively inert oxidation product, and hardly any negative effect on the ionization efficiency of analytes, compared to hydroquinone and glutathione.

Biotransformation and pharmacokinetics of tetrazepam in man.
TLDR
It seems reasonable, at least from the pharmacokinetic point of view, to attribute pharmacologic activity of tetrazepam mainly to the parent drug.
Analytical strategies for identifying drug metabolites.
With the dramatic increase in the number of new chemical entities (NCEs) arising from combinatorial chemistry and modern high-throughput bioassays, novel bioanalytical techniques are required for the…
A study of the electrospray ionisation of pharmacologically significant 1,4-benzodiazepines and their subsequent fragmentation using an ion-trap mass spectrometer.
TLDR
The data presented in this paper provide useful information on the effect of different substituents on the ionisation/fragmentation processes and can be used in the characterisation of this important class of drugs and their metabolites.
Medicolegal aspects of tetrazepam metabolism
TLDR
Toxicological analyses revealed that tetrazepam is also metabolized to diazepam and further to nordazepam, which has not yet been reported, and the importance of the detection of these newly described metabolites is shown.
Application of mass spectrometry for metabolite identification.
TLDR
The general strategies employed for metabolite identification in both drug discovery and drug development settings together with sample preparation techniques are reviewed and a discussion of the various ionization methods, mass analyzers, and tandem mass spectrometry (MS/MS) techniques used for structural characterization in a modern drug metabolism laboratory is discussed.
Detection of diazepam in urine, hair and preserved oral fluid samples with LC-MS-MS after single and repeated administration of Myolastan® and Valium®
TLDR
It is demonstrated that diazepam can be observed in urine samples even after a single dose of Myolastan®, and the possible metabolic conversion of tetrazepam todiazepam is a more plausible explanation for the detection of diazep am in biological samples after the intake of Myoliastan®,.
Liquid chromatography/atmospheric pressure ionization-mass spectrometry in drug metabolism studies.
TLDR
The feasibility of LC/API-MS techniques in the identification, structure characterization and quantitation of drug metabolites is reviewed and suitability of different MS techniques, such as tandem mass spectrometry, and high-resolution MS in drug metabolite analysis, are summarized and discussed.
Combined use of ESI–QqTOF-MS and ESI–QqTOF-MS/MS with mass-spectral library search for qualitative analysis of drugs
TLDR
Experiments revealed that because of the mass accuracy, the stability of calibration, and the reproducibility of fragmentation, the QqTOF mass spectrometer is an appropriate platform for establishment of a tandem-mass-spectral library.
Identification and differentiation of beta-blockers and their metabolites in urine by computerized gas chromatography-mass spectrometry.

A method for the identification and differentiation of beta-blockers and their metabolites in urine after acid hydrolysis is described and the identity of positive signals in the reconstructed ion chromatogram is confirmed by a comparison of the stored entire mass spectra with the reference spectra.
Gas-phase fragmentation of protonated benzodiazepines.
TLDR
Protonated 1,4-benzodiazepines dissociate in the gas phase by the common pathway of CO elimination and by unique pathways dictated by the substituents; Mechanisms of these reactions are proposed with ionic products being resonance stabilized.
