Common marmosets (Callithrix jacchus), small New World primates, are increasingly attracting attention as potentially useful animal models for drug development. However, characterization of cytochrome P450 (P450) 3A enzymes involved in the metabolism of a wide variety of drugs has remained in marmosets. In this study, sequence homology, tissue distribution, and enzymatic property of marmoset P450 3A4 orthologue, 3A5 orthologue, and 3A90 were investigated. Marmoset P450 3A forms exhibited high amino acid sequence identities (88-90%) to the human and cynomolgus monkey P450 3A orthologues and evolutionary closeness to human and cynomolgus monkey P450 3A orthologues, compared with other P450 3A enzymes...

A sensitive microextraction method based on a new poly(methacrylic acid-ethylene glycol dimethacrylate-N-vinylcarbazole) monolithic capillary column, coupled with gas chromatography-electron capture detection, was established for the determination of three benzodiazepines (estazolam, alprazolam, and triazolam) in urine and beer samples. Owing to the abundant π electrons and polar surface of N-vinylcarbazole, N-vinylcarbazole-incorporated monolith showed a higher extraction performance than neat poly(methacrylic acid-ethylene glycol dimethacrylate) because of the enhanced π-π stacking interactions derived from the π-electron-rich benzene groups from N-vinylcarbazole...

To date, thorough clean-up of complex biological samples remains an essential part of the analytical process. The solid phase extraction (SPE) technique is the well-known standard, however, its main weaknesses are the labor-intensive and time-consuming protocols. In this respect, dispersive liquid-liquid microextractions (DLLME) seem to offer less complex and more efficient extraction procedures. Furthermore, ionic liquids (ILs) - liquid salts - are emerging as new promising extraction solvents, thanks to their non-flammable nature, negligible vapor pressure and easily adaptable physiochemical properties...

Children aged between 1 to 4 years are the most at risk of unintentional poisonings. Benzodiazepines are the most medicine often cause of the poisoning. Among the twenty-two most prescribed benzodiazepines in France, lorazepam ranks fifth behind zolpidem, alprazolam, bromazepam and zopiclone. However the automated assay currently available does not allow to detect and/or to quantify lorazepam. The alternative to the immunoassay is the liquid chromatography coupled with mass spectrometry (HPLC/MS). This technique, highly sensitive and specific, requires a pre-treatment phase and a good technical proficiency, justifying specialized staff...

Alprazolam is a pharmaceutical compound that it is detected in surface waters. Some degradation studies in aqueous solutions and pharmaceutical products are available, but there is not reliable information about its stability in river water. Here, assays have been conducted under forced biological, photochemical and thermal conditions, and non-forced conditions, to estimate the fate of alprazolam in river water and know its degradation products. The forced assays indicated that the biological and photochemical degradation of alprazolam was negligible, only the heating at 70 °C for a long time affected it scarcely...
